| Abstract | This study utilized radiographic comparative analysis in order to evaluate dimensional ridge changes four months after tooth extraction and immediate grafting with mineralized dentin particulate autograft and chopped plateletrich fibrin. Fiftyeight extraction sockets with up to 2 mm of missing buccal bone in the coronal aspect compared to the lingual bone were included. Graft material was covered with either a plateletrich fibrin membrane or collagen sponge with no effort to achieve primary closure. The dimensional changes of the ridge were assessed on conebeam computed tomography (CBCT) images acquired prior to extraction and four months later. The reduction in the buccal bone plate thickness 1 mm, 3 mm, and 5 mm below the buccal crest was -0.87 ± 0.84 mm, -0.60 ± 0.70 mm, and -0.41 ± 0.55 mm, respectively. The mean ridge width changes 1 mm, 3 mm, and 5 mm below the crest were -1.38 ± 1.24 mm, -0.82 ± 1.13 mm, and -0.43 ± 0.89 mm, respectively. The average midbuccal bone height gain was +1.1%, while the midlingual height gain was 5.6%. A mineralized dentin autograft with plateletrich fibrin is effective in preserving postextraction alveolar ridge dimensions. |
