Abstract
Introduction: The aim of this study was to compare the effects of hydroxyapatite (HA), deproteinized bovine bone (DPB), human-derived allogenic bone (HALG), and calcium sulfate (CAP) graft biomaterials placed post extraction for future implant therapy in maxillary 1st molar area placed by guided tissue regeneration. Material and methods: We conducted a retrospective study. Thirty-two subjects were divided into four groups: DPB, HALG, HA, and CAP. Alveolar bone width at specific implant sites were assessed using sagittal and cross‐sectional CBCT images prior grafting and at three subsequent time points. Results: The vertical and horizontal dimensions did not significantly differ between bone grafts at any time point. In addition, there were no statistically significant differences in graft remodeling rates between grafts Conclusion: Deproteinized bovine bone bone blocks showed equivalent volumetric shrinkage rates as man-derived allogenic bone (HALG), and calcium sulfate (CAP) graft biomaterials when used for treating circumscribed bone defects. Therefore, it is not necessary to over‐contour the ridge in the maxillary molars.
