Use of HTR synthetic bone as an augmentation material in conjunction with immediate implant placement: a case report

Immediate placement of dental implants (DI) in fresh extraction sockets is associated with remaining voids around the DI and often a partial dehiscence or thin facial alveolar plate. Bioplant HTR synthetic bone (HTR) was used as a ridge preservation/augmentation material in conjunction with this method of DI placement. A 61-year-old white woman requiring extraction of tooth 12 opted for immediate DI placement. HTR was used to fill the remaining socket void and enhance the facial ridge width, and primary closure was attempted with sutures. DI uncovering was performed at about 6 months. Measurements were taken to the nearest 0.5 mm of the internal socket width and total site width at DI placement and uncovering. The internal socket width was essentially maintained (6.8 vs 6.6 mm), and the total ridge width showed a change from 8.7 to 9.1 mm. The results of this case suggest that HTR is a useful adjunct in the placement of immediate DIs for the preservation of ridge width.
