Abstract
After tooth extraction, alveolar ridge loss due to resorption is almost inevitable. Most of this bone loss occurs during the first six months after the extraction procedure. Many studies have indicated that applying socket-filling biomaterials after extraction can effectively reduce the resorption rate of the alveolar ridge. The purpose of this study was to investigate the clinical efficacy of the application of a hydroxyapatite/β-tricalcium plus collagen (HA/β-TCP + collagen) dental bone graft in dental sockets immediately after tooth extraction, so as to prevent socket resorption. The study was conducted on 57 extraction sockets located in the mandible and maxilla posterior regions in 51 patients. HA/β-TCP + collagen was inserted into all of the dental sockets immediately after extraction, and was covered with a flap. Follow-up was performed for three months after extraction, using radiographs and stents for the vertical and horizontal alveolar ridge measurements. A minimal alveolar bone width reduction of 1.03 ± 2.43 mm (p < 0.05) was observed. The height reduction showed a slight decrease to 0.62 ± 1.46 mm (p < 0.05). Radiographically, the bone height was maintained after three months, indicating a good HA/β-TCP + collagen graft performance in preserving alveolar bone. In conclusion, the HA/β-TCP + collagen graft demonstrated adequate safety and efficacy in dental socket preservation following tooth extraction.

Summary
Bone resorption has long been an inevitable result of tooth extraction. The severity of bone loss directly affects the success rate of subsequent dental implant procedures, and the post-treatment aesthetic results [1,2,3,4,5]. Numerous studies have shown that after tooth extraction, approximately 30% of the alveolar ridge is lost as a result of resorption. Studies have shown that during the first three months after extraction, approximately two-thirds of the affected hard and soft tissues undergo some degree of resorption. Most of the bone loss occurs during the first six months after the procedure. An estimated 50% of the alveolar bone width is lost within 12 months after the extraction, 30% of which occurs within the first 12 weeks.
