The prescription that was sent to the lab ordered a partial denture fabri- cated from duracetyl resin and to develop a tooth born surgical guide. The lab was instructed to simu- late the extraction site by removing the tooth from thestudycastprovided.Thismodelwasduplicatedfor fabrication of the two appliances. Laboratory product was provided to surgeon. Atraumatic extraction was accomplished and the temporary partial denture was immediately im- planted (Legacy Three, Implant Direct), placed with facial bone grafting (Figs. 2 & 3). There was a healing screw placed and the site was closed with appropriate membrane and suturing techniques.Theunilateralpartialdenturewasnotde- liveredattimeofsurgery. Thepatientwasseeninthe restorative office and the temporary partial denture (Duratek, Drake Precision Laboratories) was modified to provide tissue support and begin development of an ovate tissue site. The partial denture was placed uneventfully. These appliances are extremely reten- tiveandnotsubjecttodislodgementorpressureover theimplantsiteduringfunction.Thepatientwasseen one week later for a postoperative check and adjust- ment of the temporary appliance (Fig. 4). The patient was instructed to return to surgical clinic in approxi- mately four months for a final evaluation prior to restorative procedures. Fourmonthsaftersurgery,thepatientwasseenbythe surgeon to uncover the implant, remove the healing screw and place a temporary abutment. The tempo- rary partial was adjusted to accommodate the added height of the healing abutment (Fig. 5).
