THE APPLICATION OF DEPROTEINIZED BOVINE BONE-MINERAL FOR RIDGE PRESERVATION PRIOR TO IMPLANTATION - CLINICAL AND HISTOLOGICAL OBSERVATIONS IN A CASE-REPORT

ALVEOLAR RIDGE PRESERVATION FOLLOWING tooth extraction is important wh en implant-supported oral rehabilitation is considered. The ability to maintain the ridge allows implant placement in an ideal position, ful filling both functional and esthetic demands. A deproteinized bovine b one mineral (DBBM) was used as a socket site filler material to mainta in ridge configuration, without applying an occlusive membrane. The ma terial was grafted and packed onto the socket sites immediately after extractions, and subsequently primary soft tissue closure was attempte d. The ridge healed for 9 months before the second surgical procedure, in which the implant was placed. New bone formation was observed in a ll histological specimens. DBBM particles adhered to a highly osteocyt e-rich woven and lamellar-type bone. Clinically and histologically, th is report demonstrated DBBM particles to be an effective biocompatible filler agent in extraction sockets for ridge preservation prior to ti tanium fixture implantation. Randomized controlled clinical trials are needed to fully evaluate the usefulness of this material in ridge pre servation after tooth extraction.
