ABSTRACT
INTRODUCTION:
Tooth extractions can result in alveolar bone dimensional changes, necessitating additional bone grafting for implant placement. Alveolar Ridge Preservation (ARP) aims to counteract post-extraction changes. This study evaluates the bone regenerative properties of a freeze-dried bone allograft (FDBA) and the clinical outcomes of implants in grafted extraction sites. MATERIALS ANDMETHODS:
This case series enrolled 33 patients undergoing single/multiple tooth extractions followed by ARP. Biopsies were harvested during implant placement for histologic and histomorphometric analysis. Clinical outcomes included marginal bone loss and Pink Esthetic Score (PES).RESULTS:
25 patients completed the study. FDBA augmented sockets exhibited new bone formation adjacent to graft particles. Implants (n=25) showed 100% survival and success rates at 1 and 2 years. PES improved significantly over time (p<.001), while marginal bone loss did not significantly differ at 1 and 2 years (p=.096). Specimens showed trabecular bone, residual FDBA particles, and marrow spaces. High magnification revealed immature bone and woven bone bridges around graft particles. No inflammatory cells were observed.CONCLUSIONS:
The case series provides valuable insights into ARP performed with FDBA; implants were placed after 3 months of healing without any additional bone augmentation, the histologic outcomes were favorable, and implants were successful after a 2-year period of follow-up.
