Purpose: In this retrospective study a histomorphometric analysis was conducted of sites where alveolar ridge preservation was performed using deproteinized porcine bone mineral.
Materials and Methods: Twenty-five patients who underwent ridge preservation after extraction were selected in this study. Histomorphometric analysis was performed according to the healing period (24 weeks) and socket location. The proportions of new bone, residual bone graft material, and fibrovascular tissue were calculated. The demographic characteristics of the two groups were compared using the t-test for continuous variables.
Results: The healing duration groups showed no significant differences between the proportions of new bone (p = .692), residual graft (p = .875), and fibrovascular tissue (p = .619). The non-molar and molar area groups showed no significant differences between the proportions of new bone (p = .999), residual graft (p = .638), and fibrovascular tissue (p = .723). The maxilla and mandible groups showed no significant differences between the proportions of new bone (p = .185), residual graft (p = .736), and fibrovascular tissue (p = .125).
Conclusion: No significant differences were observed between the results of the histomorphometric analysis of the two groups based on the healing duration and location.
