Original Study

Abstract

In order to preserve the original ridge dimensions following tooth extraction and promote bone regeneration of the residual alveolar socket, various bone grafts and substitutes were used. Among these grafting materials, bovine bone xenograft was used in order to promote bone regeneration. The aim of this study was to evaluate the effectof bovine bone graft on the preservation of buccal plate of bone of extracted socket.Twelve patients with non-restorable maxillary tooth or remaining root were included in this study. They were divided equally into two groups. Group A: augmentation with bovine xenograft was performed after extraction. Group B: Extraction was performed without grafting. Delayed-immediate implants were placed for all patients at eight weeks after extraction. There was no significant difference in buccal cortical plate thickness between the two groups with. There was a significant increase in bone density of the study group at six months postoperatively. It was concluded that buccal plateaugmentation by the “pouch technique” is not enough to compensate the bone loss that occurs in the buccal wall after extraction.
