They are a cornerstone of modern restorative dentistry, offering a permanent and aesthetically pleasing way to rebuild a patient's smile and restore their ability to chew and speak with ease. Meeting this need requires a blend of clinical skill and advanced technology to deliver predictable, high-quality outcomes.
The challenge lies in choosing the right solution for each unique patient scenario, from a single missing tooth to a full edentulous arch. Fixed prostheses provide the stability and security that many patients crave, eliminating the worries associated with removable dentures. By understanding the full range of available fixed options, you can better guide your patients toward a solution that fits their clinical needs, lifestyle, and long-term health goals. The advancements in digital dentistry have made these treatments more accessible and precise than ever, allowing us to create restorations that integrate seamlessly with the patient's existing dentition and provide durable, beautiful results that stand the test of time.
An Introduction to Fixed Prosthetic Solutions
Fixed prosthetic solutions are designed to be a permanent part of a patient's smile. Unlike removable options like partial or full dentures, these restorations are securely attached in the mouth, typically by being cemented or bonded to existing teeth or dental implants. Because they are not taken out, they offer a level of convenience and confidence that many patients find life-changing. The primary goal of any fixed prosthesis is to provide a reliable and visually appealing replacement that restores proper function. Whether you are addressing a single damaged tooth or an entire arch, the result should feel stable and natural, allowing the patient to forget they even have a restoration.
Achieving this seamless integration requires incredible precision, which is why digital workflows have become so valuable. When you design a prosthesis digitally, you can ensure an exact fit that minimizes the need for chairside adjustments and reduces patient discomfort. This modern approach also allows for the use of advanced materials that offer superior strength and aesthetics. For example, AvaDent's monolithic design creates a prosthesis that is significantly stronger and more bacteria-resistant than traditional dentures. By combining a secure fit with high-performance materials, you can provide a fixed solution that not only looks great but is also built for long-term success and patient health.
Replacing Single or Multiple Teeth
When a patient is missing only one or a few teeth, the focus is on restoring the smile while preserving as much of the healthy surrounding structure as possible. Fixed prosthetics are an excellent choice for these common clinical situations because they provide a durable and non-removable solution that blends in with the natural dentition. The two most well-known options for replacing a small number of teeth are crowns and bridges. Each serves a distinct purpose, but both are designed to restore the integrity of the dental arch, improve function, and deliver a natural-looking aesthetic that gives patients the confidence to smile freely again.
Crowns
A dental crown is essentially a custom-made cap that is placed over a single damaged or decayed tooth. Its purpose is to restore the tooth's original shape, size, and strength while also improving its appearance. Crowns are an ideal solution for teeth that are cracked, severely worn down, or have undergone root canal therapy. By covering the entire visible portion of the tooth, a crown provides comprehensive protection and reinforcement, allowing a compromised tooth to function properly for years to come.
Bridges
When a patient has one or more missing teeth in a row, a dental bridge can be used to "bridge" the gap. A traditional bridge consists of one or more artificial teeth, known as pontics, which are held in place by crowns attached to the adjacent natural teeth, called abutments. This creates a single, solid restoration that fills the empty space, preventing neighboring teeth from shifting and restoring the patient's ability to chew properly. It's a reliable and time-tested method for replacing multiple teeth without resorting to a removable appliance.
Full-Arch Tooth Replacement
For patients who are fully edentulous, fixed prostheses supported by dental implants offer a transformative solution. The majority of dental implants placed each year are used to support fixed restorations, providing a stable foundation for full-arch crowns and bridges. This approach gives patients the security and function of a permanent set of teeth, a significant improvement over traditional removable dentures. Solutions like the AvaMax hybrid combine a precision-milled titanium substructure with high-density PMMA, delivering a prosthesis that is not only incredibly strong but also lightweight and beautiful. This digital approach ensures a passive, precise fit that promotes the long-term health of the implants and surrounding tissues.
Tooth-Supported vs. Implant-Supported Prostheses
Fixed prosthetics are defined by how they are anchored in the mouth. A tooth-supported prosthesis, like a traditional bridge, relies on healthy adjacent teeth for support. This often requires preparing those teeth by removing some enamel to fit the crowns that will hold the bridge in place. In contrast, an implant-supported prosthesis is anchored directly to dental implants that have been surgically placed in the jawbone. This method is often preferred because it doesn't require altering healthy teeth. Furthermore, because implants integrate with the bone, they help preserve jaw structure and provide a remarkably stable foundation for crowns, bridges, and full-arch restorations.
What is a Locator Fixed Prosthesis?
As a clinician, you’re always looking for effective ways to meet your patients' needs, especially for those who are fully edentulous. The locator fixed prosthesis is a fantastic full-arch solution that fills the crucial gap between removable overdentures and more complex fixed restorations. It offers patients the security and confidence of permanent teeth without the surgical complexity or financial commitment of some alternative treatments. Think of it as a way to provide a life-changing upgrade for your denture patients.
How Does a Locator Fixed Denture Work?
The locator fixed prosthesis is a permanent, full-arch restoration that is secured in the patient's mouth but can be removed by you for maintenance. The mechanism builds on a system many clinicians are already familiar with, using LOCATOR abutments that attach to dental implants. A patient will typically need a minimum of four implants to support the prosthesis. Special housings are processed into the denture, which then snap onto the abutments. This creates a secure, stable connection that gives patients a fixed-in-place experience while offering a straightforward workflow to convert existing dentures into a permanent solution.
Locator Fixed vs. Traditional Dentures: What's the Difference?
For patients accustomed to traditional removable dentures, the difference is night and day. A locator fixed prosthesis eliminates the need for messy adhesives and the daily anxiety of a denture that might slip or click while talking or eating. It provides a more accessible fixed option for patients who may not be candidates for more invasive procedures. When paired with advanced materials, the results are even better. For example, the AvaMax prosthesis uses a monolithic design that combines a durable titanium substructure with a high-density PMMA exterior. This delivers the exceptional strength needed for a long-lasting restoration along with the beautiful, natural-looking esthetics your patients desire.
Why Choose Locator Fixed Prosthetic Solutions?
When you're guiding an edentulous patient through their options, the conversation often centers on achieving a final result that feels secure, looks natural, and functions comfortably. A Locator fixed prosthesis delivers on all these fronts, offering significant clinical advantages over traditional removable dentures. This fixed-removable solution provides the stability of an implant-supported restoration while still allowing for straightforward maintenance by you, the clinician. For your patients, this means a dramatic improvement in their quality of life, from eating their favorite foods with confidence to smiling without a second thought. For your practice, it means delivering predictable, high-quality outcomes that build patient trust and satisfaction.
Give Your Patients Unmatched Stability and Confidence
One of the most significant challenges with conventional dentures is the lack of stability, which can lead to discomfort, difficulty eating, and social anxiety for patients. Locator fixed cases are an innovative solution for edentulous patients who seek superior denture stability and improved function. By anchoring the prosthesis to dental implants using Locator abutments, you can virtually eliminate the slipping and shifting that plagues so many denture wearers. This secure attachment gives patients the confidence to speak and chew without fear of their prosthesis dislodging, providing a life-changing improvement in their daily function and overall well-being.
Restoring Full Biting and Chewing Power
Imagine the look on your patient's face when they realize they can bite into an apple or enjoy a steak for the first time in years. This is the reality you can offer with a locator fixed prosthesis. Unlike traditional dentures that rest on the gums and can shift under pressure, this solution is anchored directly to implants, providing a stable foundation that mimics the function of natural tooth roots. This direct connection is what allows patients to regain strong biting power, enabling them to chew food properly and enjoy a much wider, more nutritious diet. It’s not just about stability; it’s about restoring one of life’s simple pleasures and dramatically improving their overall health and confidence at every meal.
Enhance Daily Comfort for Eating and Speaking
A secure fit directly translates to greater comfort. Because a Locator fixed prosthesis is implant-retained, it doesn’t rely on suction or adhesives, which reduces gum irritation and sore spots. The design also allows for a palate-less upper prosthesis, which feels less bulky and improves the patient's sense of taste and speech. Advanced materials further enhance the patient experience. For example, the AvaMax hybrid solution combines a strong titanium substructure with a high-density PMMA outer layer. This creates a prosthesis that is not only durable but also lightweight, stain-resistant, and comfortable for all-day wear, making daily function feel effortless and natural again.
A More Natural Feel Than Removable Options
The ultimate goal for any restoration is to mimic the feel of natural teeth, and a locator fixed prosthesis excels at this. Your patients can leave behind the daily inconvenience of adhesives and the persistent fear of their denture slipping during a conversation or meal. This secure, implant-retained connection provides a profound psychological lift by restoring confidence and also transforms their sensory experience. For patients with an upper prosthesis, the palate-less design is particularly impactful. It eliminates the bulky feeling of a traditional denture, allowing them to experience the full taste of their food and speak with greater clarity. It’s about returning the simple, everyday functions that make life feel normal again.
Create a Beautiful, Natural-Looking Smile
Your patients want a smile that not only functions well but also looks beautiful and authentic. Digital design and manufacturing processes have revolutionized prosthetic aesthetics, allowing for incredibly precise and personalized results. AvaDent’s monolithic digital dentures are designed and milled with exacting accuracy, ensuring a seamless fit and lifelike appearance.

The result is a prosthesis that complements your patient’s facial features perfectly, moving far beyond the one-size-fits-all look of traditional dentures and restoring a truly confident smile.
Support Better Long-Term Oral Health
While the immediate benefits are clear, a Locator fixed prosthesis also supports better long-term oral health. The implants help preserve jawbone density, preventing the facial collapse that often occurs after tooth loss. The stability of the prosthesis also prevents chronic irritation of the soft tissues. Of course, success depends on a partnership between you and your patient. It’s critical that patients perform routine hygiene and that you establish a professional maintenance schedule. Regular check-ups to clean the components and assess the implants are essential for the longevity of the prosthesis and the health of the surrounding tissues, as outlined in the LOCATOR Overdenture Implant System guidelines.
Materials Used for Fixed Prostheses
Choosing the right material is one of the most critical decisions you'll make when planning a fixed prosthesis. The material directly impacts the restoration's strength, longevity, aesthetics, and biocompatibility. For years, the industry standard was predictable and reliable, but patient expectations have evolved. They’re looking for solutions that are not only functional but also indistinguishable from natural teeth. This has pushed material science forward, giving us an incredible range of options, from time-tested metal-ceramics to advanced all-ceramic and hybrid solutions. Understanding the unique properties of each material allows you to tailor your treatment plan to the specific clinical situation and deliver a result that meets both your standards and your patient's desires.
Traditional Metal-Ceramic Restorations
For decades, porcelain-fused-to-metal (PFM) restorations were the gold standard for crowns and bridges, and for good reason. They offer a proven track record of strength and durability, thanks to a metal framework layered with veneering ceramic. This combination provides the robust support needed to withstand occlusal forces, making them a reliable choice for posterior teeth and long-span bridges. While they have a long history of clinical success, their primary drawback is aesthetics. The underlying metal can sometimes create a dark line at the gumline, and the opaque nature of the restoration can make it difficult to achieve the natural translucency of enamel, which has led many clinicians to explore more modern alternatives.
Modern Metal-Free Options
The demand for more natural-looking restorations has fueled the rise of metal-free options. These materials eliminate the aesthetic challenges of PFM crowns, offering superior translucency and a more seamless blend with the patient's existing dentition. A fixed dental prosthesis made from modern ceramics can replicate the look of a natural tooth with incredible accuracy. Materials like zirconia and lithium disilicate have become go-to choices in cosmetic dentistry, each with its own set of advantages depending on the clinical requirements of the case. They allow you to provide strong, durable, and beautiful restorations without compromising on biocompatibility.
Full Zirconia
Full zirconia has become a powerhouse material in restorative dentistry, prized for its exceptional strength and fracture resistance. This makes it an ideal choice for posterior crowns and bridges where durability is the top priority. While early versions were criticized for being too opaque, newer formulations offer improved translucency, making them more versatile for a wider range of applications. It's a reliable workhorse material that provides both function and good aesthetics.
Lithium Disilicate
When aesthetics are paramount, lithium disilicate is often the material of choice. It is renowned for its excellent optical properties, including a natural-looking translucency that mimics enamel beautifully. This makes it perfect for anterior restorations like crowns, veneers, and inlays. While not as strong as zirconia, studies have shown that bridges made from lithium disilicate can have fewer complications, like chipping, than their metal-ceramic counterparts over the long term, making it a fantastic blend of beauty and durability.
Advanced Hybrid Materials
Innovation in dental materials has led to the development of hybrid solutions that combine the best properties of different materials into one prosthesis. These advanced options aim to deliver both elite strength and superior aesthetics without compromise. A perfect example is the AvaMax hybrid prosthesis, which is built on a precision-milled titanium substructure for incredible durability and a secure fit. This strong foundation is then fused with a monolithic, high-density PMMA exterior that provides beautiful, natural-looking aesthetics. This combination creates a restoration that is not only incredibly strong and long-lasting but also lightweight, stain-resistant, and gentle on opposing dentition.
Research on Material Performance and Longevity
With so many options available, it's easy to wonder if there's one "best" material. The clinical research provides valuable guidance, but it also highlights the complexity of the decision. Currently, there isn't enough conclusive evidence to definitively say that metal-free materials outperform traditional metal-based restorations in every single scenario. The truth is, material selection is case-dependent. Factors like the location of the restoration, the patient's bite forces, and aesthetic demands all play a role. The most successful outcomes come from carefully matching the material's properties to the unique clinical needs of each patient, ensuring a durable and beautiful result that stands the test of time.
Comparing Top Locator Fixed Systems
When you’re ready to add a locator fixed prosthesis to your practice’s offerings, you’ll find several systems on the market. While they all aim to provide a stable, full-arch solution for edentulous patients, they differ in materials, design, and clinical workflow.

By dedicating time to these considerations, you minimize surprises down the road and reinforce the value of the care you provide. This approach also helps in identifying potential roadblocks early, whether they are clinical, financial, or psychological, allowing you to create a more tailored and effective treatment strategy for each individual. Ultimately, a well-considered plan is the bedrock of predictable, high-quality results that both you and your patient can be proud of.
Is Your Patient a Good Candidate?
The initial consultation is your opportunity to understand a patient’s goals and determine if they are a good candidate for a locator fixed prosthesis. Many patients aren't aware that a stable, fixed solution is within reach. It's our job to educate them on their options beyond traditional removable dentures. Often, patients have deep-seated functional or psychological concerns about removable prosthetics, making them prime candidates for a fixed solution. You can grow your implant practice by proactively discussing these advanced treatments and addressing any fears they have about the surgical process. A candidate who strongly desires a fixed solution and understands the procedure is already on the path to a successful outcome.
Assessing Gum and Bone Tissue Loss
A comprehensive clinical assessment is the first step in determining candidacy. This goes beyond a simple visual check; you need to evaluate the quality and quantity of the patient's bone and surrounding soft tissues. This is the foundation upon which the entire restoration will be built. Implants are a game-changer here because they actively help preserve jawbone density, preventing the facial collapse that often follows complete tooth loss. A stable prosthesis also prevents the chronic soft tissue irritation common with ill-fitting dentures. A thorough assessment ensures you can create a treatment plan that not only restores a beautiful smile but also supports lasting oral health for your patient.
The Importance of Implant Strategy
Once you've assessed the patient's anatomy, the next step is to map out your implant strategy. This isn't just about picking spots; it's about creating a blueprint for a predictable and successful outcome. A locator fixed prosthesis typically requires a minimum of four implants to create a stable, supportive base that can withstand functional forces. The placement must be precise to distribute chewing forces evenly and ensure the final prosthesis functions correctly without rocking or instability. A well-thought-out implant strategy is crucial for achieving a predictable outcome, which is why understanding the different implant systems available is so important for tailoring the treatment to each patient.
Discussing Costs and Insurance with Patients
Financial discussions can be challenging, but transparency is key to building trust. Many patients are concerned about the cost of dental procedures, so it’s helpful to frame the locator fixed prosthesis as an accessible and valuable investment in their quality of life. This solution was developed to provide the security of a fixed prosthesis at a more manageable price point than many traditional options. Be prepared to have a clear and direct conversation about the total fees and what their insurance may or may not cover. For patients who are still hesitant, you can explain the flexibility of some systems, which can allow for a transition between fixed and removable options if their needs or financial situation changes down the line.
Key Factors That Influence Treatment Cost
When you're breaking down the costs for a patient, it’s helpful to explain that the final price is influenced by several key factors. The scope of the treatment is a major one; a full-arch replacement will naturally be a larger investment than a single crown. The materials used also play a significant role, as advanced options like zirconia or the high-quality titanium and PMMA found in premium hybrids come at a higher cost but offer superior durability and aesthetics. Additionally, the complexity of the case, your clinical experience, and the fees from the dental lab all contribute to the total investment. Being transparent about these variables helps patients understand the value behind the treatment and feel more confident in their decision.
Answering Your Patient's Top Questions
Patients will naturally have questions, and your ability to answer them clearly will build their confidence. Be ready to explain how the system works in simple terms. You can describe how it uses existing LOCATOR abutments and a custom-milled prosthesis that is securely seated with special inserts. Many will want to know how it compares to other fixed options. This is your chance to highlight the benefits of stability, comfort, and improved function. Having a case study on hand can be a powerful visual tool to help patients understand the process and see the transformative results for themselves, making the treatment feel more tangible and less intimidating.
How to Care for a Locator Fixed Prosthesis
A locator fixed prosthesis is a significant investment in a patient's quality of life, and its success depends heavily on diligent, long-term care.

The Ideal Daily Care Routine for Patients
Your patient is the primary caretaker of their prosthesis, so clear, simple instructions are essential. Emphasize that daily cleaning is non-negotiable for preventing plaque buildup, inflammation, and odor. Instruct patients to gently clean their prosthesis every day using a soft-bristled brush and warm water. For a deeper clean, they can use a non-abrasive denture cleaner. It's also crucial to remind them to care for their locator overdentures by cleaning around the locator attachments in their mouth to keep the surrounding tissue healthy. Providing a printed or digital care sheet can help patients remember these steps and feel more confident in their new routine.
Proper Flossing Techniques
Proper hygiene around the implants is critical for the long-term health of the surrounding tissues. Teach your patients to be thorough but gentle. The goal is to clean the area where the prosthesis meets the gumline without causing trauma. Water flossers are an excellent tool for this, as they can effectively flush out debris from hard-to-reach areas. If using traditional floss, emphasize the importance of a gentle approach. Patients should guide the floss carefully around the abutments and avoid snapping it into the gumline to protect the delicate peri-implant seal. Interproximal brushes can also be very effective for cleaning between the components and ensuring the entire area remains free of plaque.
Dietary Recommendations for Longevity
One of the greatest benefits for patients is the ability to enjoy a wider variety of foods with confidence. The secure fit of a locator fixed prosthesis means they can eat comfortably without the fear of slippage. This is especially true with a palate-less upper design, which improves the sense of taste and makes eating more enjoyable. Encourage patients to embrace a balanced diet rich in nutrients that support oral and overall health. While the prosthesis is strong, it's still wise to advise them to avoid extremely hard items like ice or hard nuts, or very sticky candies, which could potentially damage the acrylic or stress the components over time.
Managing Foods and Drinks That Stain
Patients often worry about their new smile losing its luster. This is a great opportunity to discuss the advantages of modern materials. The AvaMax hybrid solution, for example, uses a high-density PMMA that is specifically designed to be bacteria and stain-resistant, making maintenance much simpler for the patient. While these advanced materials offer excellent protection, good habits are still important. Advise patients to rinse their mouths with water after consuming common culprits like coffee, tea, or red wine. This simple step can go a long way in preserving the beautiful, natural-looking aesthetics of their restoration for years to come, ensuring they remain proud of their smile.
Your Guide to Professional Maintenance Checks
While daily patient care is the foundation, your professional oversight is what ensures optimal longevity. Routine maintenance appointments are critical for inspecting the prosthesis, abutments, and surrounding soft tissues. These check-ups allow you to identify any early signs of wear on the components, assess the patient's hygiene habits, and make necessary adjustments before minor issues become significant problems. A good starting point is to schedule an in-office implant maintenance appointment every three to six months. You can then tailor this frequency based on the individual patient’s needs, oral hygiene, and the specific wear patterns you observe over time.
When to Replace Dental Implant Locator Attachments
Just like any high-performance system, a locator fixed prosthesis has components that will wear out over time and require replacement. Setting this expectation with patients from the beginning is key to a successful long-term treatment plan. The LOCATOR FIXED® Inserts, in particular, are designed for routine maintenance. During check-ups, you should inspect them for signs of wear or loss of retention. While every patient is different, some research suggests that locator abutments last around three years before needing replacement. By creating a proactive replacement schedule, you can maintain the restoration’s stability and function, preventing patient frustration and emergency appointments down the road.

What's the best way to explain the "fixed but removable" concept to patients? It’s helpful to frame it in terms of their daily experience versus professional care. You can explain that for them, it functions just like permanent teeth—it stays in place securely while they eat, talk, and smile, with no daily removal required. Then, clarify that its unique design allows you, their clinician, to easily remove it during check-ups for thorough cleaning and maintenance, which helps ensure the long-term health of their implants and the prosthesis itself.
What does a typical professional maintenance appointment involve? A routine maintenance visit is quite efficient. You will remove the prosthesis to thoroughly clean it and the underlying abutments. This is your opportunity to inspect the LOCATOR inserts for any signs of wear and replace them as needed to maintain ideal retention. You'll also assess the health of the implants and the surrounding gum tissue before securely seating the prosthesis again.
