The Effectiveness of Hyaluronic Acid in Bone Regeneration

Sponsor: TC Erciyes University

Summary

Bone loss due to resorption is commonly observed in the alveolar socket following tooth extraction. This situation makes it difficult to preserve sufficient bone volume that would allow for ideal implant placement in cases requiring dental implants. Alveolar ridge preservation is a procedure aimed at minimizing bone resorption and preserving the volume and morphology of the alveolar ridge after tooth extraction. The aim of this study is to evaluate the clinical effectiveness of socket preservation using a xenograft enriched with hyaluronic acid in patients with defective extraction sockets. This study is designed as a randomized, controlled clinical trial including three parallel groups: Study group - Patients whose alveolar bone was evaluated using cone-beam computed tomography (CBCT) will undergo tooth extraction, followed by the application of a bovine-derived graft/xenograft enriched with hyaluronic acid into the socket. Patients will be evaluated clinically, radiologically, and histologically at the 4th month. Dental implants will be placed in the edentulous areas where the graft was applied. Bone samples will be taken during the preparation of the implant sockets, and the bone tissue will be examined histologically. A third CBCT scan will be taken 6 months after implant placement to assess new bone formation and implant success radiographically. Comparison group - Patients whose alveolar bone was evaluated using CBCT will undergo tooth extraction, followed by the application of a standard bovine-derived graft/xenograft into the socket. Patients will be evaluated clinically, radiologically, and histologically at the 4th month. Dental implants will be placed in the edentulous areas where the graft was applied. Bone samples will be taken during the preparation of the implant sockets, and the bone tissue will be examined histologically. A third CBCT scan will be taken 6 months after implant placement to assess new bone formation and implant success radiographically. Control group - Patients whose alveolar bone was evaluated using CBCT will undergo tooth extraction, and the socket will be left to heal naturally without the application of any graft material. Patients will be evaluated clinically, radiologically, and histologically at the 4th month. Dental implants will be placed in the edentulous areas. Bone samples will be taken during the preparation of the implant sockets, and the bone tissue will be examined histologically. A third CBCT scan will be taken 6 months after implant placement to assess new bone formation and implant success radiographically.
