    A comparison between bone grafting and non-grafting of immediately placed implants in the molar area
    (2024) Van der Linden, Wynand Johan
    Aim: This study aims to investigate the outcome of placing a bone graft material into the residual socket space of a fresh molar extraction socket, treated flapless after an implant has been placed compared with a control group at three months. Methodology: This prospective, randomized, control, double-blind clinical trial will evaluate the difference in ridge width between a control and intervention (grafting) group at baseline and three months postoperatively. All cases were evaluated using pre-operative (T0) and three months postoperative (T1) impression models. Horizontal measurements were taken at 3 levels (2, 4, and 6mm). Vertical point measurements were done at 3 points (A, B, and, C) and compared between the two groups. Results: The study consisted of 22 participants, 11 in the control and 11 in the grafting group with a mean age of 49.5 years. Majority of the cases presented in the mandible (64%) with one case of implant failure. Bone loss was perceived to be greater in the control group after 3 months compared to the loss observed in the grafting group. The difference in the loss of ridge width between the control and grafting groups was insignificant (p-value>0.05). Conclusion: The difference in the loss of ridge width between the control and grafting group was insignificant (p-value>0.05), owing to the study’s small sample size. Less bone resorption was observed in the grafting group at 3 months post– implant placement, however, the long-term follow-up would be required to determine the effectiveness of the bone graft. Further studies with larger population samples and increased follow-up time (6 months, 12 months, and 24 months) should be considered to determine the long-term benefit of bone grafting done simultaneously with tooth extraction and immediate implant placement.
