The AvaDent / Wagner EZ Guide protocol is designed to allow the clinician to produce high-quality AvaDent digital dentures in just 3, 30 minutes appointments. The technique can also be used as the basis for implant-based prostheses and can be the foundation for more sophisticated tissue-based removable prostheses as well.
Although any impression technique is accepted for final impression making, we recommend the following technique using Wagner impression trays and/or the materials of your choice.
Dentsply’s Aquasil Ultra + Fast Set impression material is demonstrated here. Aquasil Ultra + Fast Set Heavy is used for border moulding and Aquasil Ultra + Fast Set LV is used for the final impression.
Heat the maxillary impression tray in 160º F (70ºC) water for 1 minute. For details see the videos on bigjawbone.com.
Repeat for the mandibular ridge.
Place the tray in the patient’s mouth and shape the tray to the patient’s palate and alveolar ridge using border moulding motions. Again, for details, see the video on bigjawbone.com.
Repeat for the mandibular ridge.
Trim the tray with scissors or add material that is provided with each tray. The tray can be stretched. You can perforate the tray for an open tray implant impression if required. Apply tray adhesive to the trays.
Border mould the trays. For details see the videos on bigjawbone.com. Repeat for the mandibular ridge
If the tray is seen in the impression, adjust it with a carbide bur.
Perform a wash impression technique.
The incisive papilla is an important anatomic landmark when determining the position of the maxillary central incisor.
The papillameter is placed on the anterior alveolar ridge centering the incisive papilla in the middle of the instrument.
Record the length of the upper lip in mm.
Record the high smile line in mm.
Select the tooth mould and shade your choice. We offer Dentsply Portrait, Ivoclar BlueLine (SR Vivodent DCL), Ivoclar IvoStar, Candular NFC+ Candulor TCR moulds.
Adjust the bases if necessary. Check the orientation of the horizontal occlusal plane. Check the midline. Adjust the midline if necessary.
Evaluate the length and position of the central incisors. Adjust if necessary. Create a natural smile by moving the anterior teeth.
Determine the occlusal vertical dimension and record centric relation. Adjust if necessary. Position the lower anterior teeth into their proper position.
After obtaining the patient's approval, make an interocclusal record with PVS and send the Wagner Try-In to AvaDent.
