Aesthetic enhancement of pontic sites for fixed partial dentures.
The ridge expansion technique using tapered osteotomes can be used anywhere in the maxilla when a change in external ridge morphology would be advantageous for both aesthetics and/or proper dental implant placement. Usually subsequent to tooth loss, the maxilla is generally somewhat undercut in form. This ridge expansion technique can be used to reduce the undercut by bulging out the base of the facial/buccal plate. This would recreate the illusion of root prominences (Figure 12) or permit implant fixtures to be inserted in a more upright position. The tapered osteotomes can therefore predictably be used to expand the buccal bone to simulate the presence of a root prominence for optimal aesthetics for placement of a fixed partial denture prosthesis (Figure 13).
