In the described treatment, the procedure lasted 5 hours from the start of surgery until the patient left the office. Six implants were placed in the maxilla by using the immediate complete denture as a surgical guide.Procedure
- 1.Modify the existing complete denture to fit over titanium impression posts (temporary coping Ø 4; Anthogyr) (Fig. 1A, 1B ).Figure 1A, Modification of removable denture. B, Clinical appearance. C, Protection of titanium cylinders and insertion of rubber dam. D, Hole made in canine region.
- 2.Close the screw access holes with polytetrafluoroethylene (PTFE) tape, and insert a sheet of rubber dam (medium; Nic Tone) to act as a barrier for the autopolymerizing resin (Fig. 1C).
- 3.Make 2 holes on the edge of the denture at the level of the canines (Fig. 1D).
- 4.Guide the patient to a closed position and then inject acrylic resin (Unifast Trad pink; GC Corp) with a syringe through the holes. At this stage, when the resin has completely polymerized, the occlusion is locked (Fig. 2A).Figure 2A, Resin injected in canine region to lock occlusion. B, Injection in posterior region.
- 5.Carry out the same procedure at the posterior location (Fig. 2B).
- 6.After the resin has completely polymerized, remove the denture including the titanium cylinders. The rubber dam provides excellent tissue protection (Fig. 3A-C).Figure 3A, Immediately after prosthesis removal, rubber dam prevented resin flowing on mucosa. B, Intaglio surface of prosthesis. C, Cameo surface of prosthesis. D, Finished prosthesis after removal of palate and buccal extension.
- 7.Remove the flanges of the denture and adjust the intaglio surface to allow access for hygiene (Fig. 3D).
- 8.Secure the interim prosthesis with prosthetic screws, and reevaluate and adjust the occlusion (Fig. 4).Figure 4Seated interim prosthesis.
