Use of HTR synthetic bone grafts in conjunction with immediate dental implants

Immediate placement of dental implants in fresh extraction sockets is associated with remaining voids around the implants and often a partial dehiscence or thinning of the facial alveolar plate. Nine patients had Bioplant HTR synthetic bone used as a ridge preservation/augmentation material in conjunction with immediate placement of 10 implants. Hard tissue replacement (HTR) was used to fill the remaining socket void and enhance the facial ridge width, and the wound closed as completely as possible. Dental implants were uncovered at approximately 6 months. Measurements taken of the internal socket width and total ridge width at the implant placement and uncovering showed the mean internal socket width was maintained (7.2 mm vs 6.9 mm), and the total ridge width exhibited a mean change from 9.6 mm to 8.8 mm. Of the 10 implant sites, 7 showed a net increase, 2 no change, and 1 a decrease in overall ridge width. All 10 implants were restored for at least 6 months. These clinical results suggest that HTR is a useful adjunct in the placement of immediate dental implants for the preservation of ridge width and provides a good base for functional and esthetic prosthetic reconstruction.
