Aim The present article reports clinical, radiographic, and histological healing of a case of alveolar ridge preservation treated with a cortical bone allograft and a bioabsorbable collagen wound dressing membrane for the reconstruction of a damaged extraction socket with a buccal bone dehiscence.

Case report In the case reported, alveolar ridge preservation technique was applied in an extraction site with a buccal dehiscence type defect, using an allograft bone substitute and a bioabsorbable collagen wound dressing membrane followed by a successful implant placement at a later stage.

Conclusion This case report showed that alveolar ridge preservation technique in a damaged socket with buccal dehiscence, using a freeze dried bone allograft covered with a fast resorption collagen membrane, can lead to new bone formation, of up to 53.53%, and ultimately allow safe implant placement.
