BACKGROUND: Maxillary sinus augmentation is a predictable procedure to increase bone height in atrophic posterior maxilla. Different protocols and procedures for sinus lift are available. Many biomaterials are employed in this technique; however, no biomaterial has been proven as the best.
MATERIALS AND METHODS: A single-center, prospective, interventional, single-arm study was done for evaluation of the efficacy of biphasic calcium phosphate mixed in a 1:1 ratio with autogenous bone graft. Patients with ≤5 mm of subantral bone height were recruited. Sinus membrane was elevated using piezosurgical tips and sinus elevators, and a graft was placed to achieve the desired bone height. Lateral window was covered by platelet-rich fibrin membrane, and suturing was done. After 6 months, bone biopsy specimens were harvested, and histomorphometric analysis was performed. Subantral bone height was measured on cone-beam computed tomography at baseline and at 6 months to get the bone height gain.
RESULTS: (1) The mean gain of bone height was 8.53 ± 1.07 which was statistically significant. (2) On histologic evaluation, new bone% was 48.08% ± 2.41%, soft tissue% was 27.25% ± 3.18%, and residual graft% was 24.36% ± 2.91%. (3) The density and distribution of cells were favorable. (4) All patients had pain and swelling in mild range. (5) No major intra- or postoperative complications were noted.
CONCLUSION: The described surgical technique using a combination of hydroxyapatite + beta-tricalcium phosphate 30/70 along with autogenous bone in a 1:1 ratio offers a predictable and practical treatment choice in direct sinus augmentation. It provided significant bone height gain, new bone formation, and good implant stability in grafted sites.
