| Abstract | ||
| Introduction: One of the primary challenges associated with immediate implant placement was the presence of a "jumping gap" between the implant fixture and the surrounding bone. To address this issue, composite bone substitute materials were introduced. These materials, when used in conjunction with immediate implant placement, filled the gap, promoted bone formation, and enhanced implant stability and long-term success. Objectives: This study aims to compare the effects of two bone grafting materials—biphasic alloplastic β-tricalcium phosphate (ß-TCP) in a calcium sulphate matrix and β-tricalcium phosphate - clinically on implant stability, and radiographically on peri-implant bone density and crestal bone loss following immediate implant placement in mandibular molars. Materials and Methods: Twenty patients with non-restorable mandibular molars were enrolled in the study and randomly divided into two equal groups. Immediate implant placement was performed in the extraction sockets for all patients, followed by alveolar bone augmentation. In β-TCP/CS, the jumping gap was filled with biphasic β-tricalcium phosphate in a calcium sulphate matrix, while in β-TCP Group, β-tricalcium phosphate alone was used. Patients were monitored clinically and radiographically over a 7-month follow-up period. Results: The biphasic β-tricalcium phosphate in calcium sulphate matrix demonstrated statistically significant improvements in implant stability and peri-implant bone density compared to the β-tricalcium phosphate grafting material. Conclusion: The biphasic β-tricalcium phosphate in a calcium sulphate matrix emerged as a promising solution for addressing the jumping gap in immediate implant placement, offering enhanced bone formation and implant stability. | ||
