Background: Alveolar ridge preservation using bihybrid composite bone graft as an intra-socket osseous graft is one of the techniques used to preserve alveolar ridge from resorption after extraction. In addition, dental implants became a mandatory choice in prosthetic treatment plan nowadays. Bone dimensions and quality are considered an important factors to insure the stability and success of an implant.
Aim of Study: To clinically compare the stability of delayed loaded dental implants in sockets regenerated using bihybrid composite bone graft versus implants that were installed in nongrafted sockets.
Material and Methods: This study was conducted on twenty-two sockets, 11 of them with preplaced bihybrid composite bone graft after extracting unrestorable teeth and the other group with native bone. After 6 months, osteotomy was prepared and implant was placed. Primary stability was measured using resonance frequency analysis (osstell device). After 4 months secondary stability was also measured.
Results: Twenty-two implants were inserted in extraction sockets of twenty patients, 8 males, 12 females. No statistically significant difference in primary and secondary stability between both groups was found. The mean primary stability for the study group was 56.00 ±5.98, while for the control group was 51.18 ±7.96 (P= 0.124). The mean secondary stability for the study group was 61.82 ±3.31, while for the control group 58.82 ±7.19 (P=0.223).
Conclusion: Grafting sockets using bihybrid composite bone graft does not enhance implant stability.
