Keep Neighboring Tooth Temporarily as Reference for Implant Placement
A 53-year-old woman has toothache in the upper left sextant. It appears that the teeth #15 and 16 are non-salvageable due to proximal root caries (Fig.1 *). The tooth #15 is extracted first and the socket will be packed with 2% Xylocaine, 1:50,000 Epinephrine gauze. The decay at #16 will be removed to reduce intraop contamination (Fig.3 *), followed by insertion of a piece of gauze (Fig.3 white). Rounded tapered (RT) osteotomes (Fig.3 red arrow) or drills will be used for sinus lift (Fig.1 ^: sinus floor). With the 3rd molar temporarily in site, the trajectory of the osteotomy is easily controlled.
Once an implant is placed at the site of #15, the tooth #16 is extracted (Fig.4). With a piece of gauze in the implant well, allograft/Osteogen is placed around the implant (Fig.5 red circle), while collagen plug in the socket of #16 (Fig.5 brown) if necessary. After removal of the gauze from the implant well, an abutment is placed (Fig.5 pink). More graft is placed around the implant shoulder (Fig.6 white circles). An immediate provisional at #15 could be extended distally to cover the #16 socket (Fig.7 yellow). Two weeks later the provisional is modified (Fig.7 grey dashed line) to remove the distal extension.
