D Implant for Lower Molar?
A Caucasian lady has a failing bridge in the lower right quadrant. After sectioning the bridge, the tooth #31 is extracted and an immediate implant is placed (7X11 mm). A 5x14 mm tapered implant is planned to be placed at the site of #30 six weeks later (Fig.1,2). Since the top of the ridge is severely atrophic and the mesiodistal width is quite wide, I wonder whether we should place a D2 or 3 short implant instead. My concern is how to create a D shaped osteotomy without offset D osteotomes, although bone scalpel and bone blade osteotomes can be used to create an initial osteotomy. Thanks.
