ABSTRACT: Objective: To evaluate the radiographic outcomes of guided bone regeneration using Bond Apatite, a calcium sulphate-based bone graft material combined with hydroxyapatite—for lateral bone augmentation. Method: Two diabetic patients with lateral bone deficiencies underwent the procedure using the same surgical protocol. Computed tomography radiographs were taken immediately prior to the placement of the Bond Apatite. Follow-up radiographs were taken three months after placement for Patient 1 and seven months after placement for Patient 2. Results: Radiographic imaging with cone beam computed tomography (CBCT) revealed significant bone regeneration: Patient 1 exhibited a 4 mm increase in bone thickness and Patient 2 showed a 7 mm increase. The study found that the shape and depth of the bone defects influenced the amount of bone regenerated: deeper, more retentive defects yielded more bone. It was also discovered that bone regeneration occurred beyond the bone defects being filled and that the amount regenerated depended on factors such as stimulation of the bone walls and their retentive characteristics. Conclusion: These results suggest that Bond Apatite effectively promotes bone regeneration, offering a simplified and rapid approach to challenging bone defect cases.
