Abstract
Aim: The present study aims to determine the efficacy of bovine hydroxyapatite and collagen (G-graft) mixed with platelet-rich fibrin (PRF) used as a scaffold and chorion membrane as a barrier in post-extraction sockets with extraction sites alone.Methods and material: Thirty individuals were randomly assigned into two groups. In the control group, after debridement of the extracted tooth socket, no additional treatment was done. In the test group, after debridement of the extracted tooth socket, the sockets were filled with bovine hydroxyapatite and collagen (G-graft) mixed with PRF. They were covered by a chorion membrane, and a non-absorbable suture material was used to secure the membrane in place. Clinical parameters assessed were plaque index, gingival index, buccolingual width, buccal bone plate height, and lingual bone plate height at baseline and at six months.Results: Clinically, there was a more significant reduction in the buccolingual width of the control group than the test group after six months. A statistically significant difference between the two groups for vertical ridge height at the mesial and distal socket sites was observed. No statistically significant difference in buccal and lingual bone plate height was observed between the two groups (p>0.05).Conclusions: Both groups showed a significant reduction in the Buccolingual width, but it was less in the ridge preservation group. Thus, the use of G-graft with PRF and chorion membrane was highly effective in ridge preservation.Key messages: Natural bovine bone mineral, along with PRF and chorion as a membrane, can be utilized effectively for ridge preservation in extracted tooth sockets due to periodontal disease.
Highlights
The success of implant therapy depends on the prosthetic-driven position of the implant, bone to implant contact, an adequate number of ridge contours, and proper surgical procedure [1]

Summary
The success of implant therapy depends on the prosthetic-driven position of the implant, bone to implant contact, an adequate number of ridge contours, and proper surgical procedure [1]. Ridge preservation is a surgical procedure carried out after extraction to prevent the collapse of the ridge and to preserve the ridge dimension, as usual, for implant site development [3]. For this purpose, allografts, alloplastics, and xenograft materials, along with autogenous bone, can be utilized [4,5,6]. The addition of platelet-rich fibrin (PRF) to the graft materials enhances wound healing and hemostasis, bone growth and maturation, and bone density, which impart better handling properties to the graft materials [7]. In vitro studies revealed that PRF induces various cell proliferation with the most potent induction effect on osteoblasts [8]
