Abstract:
PURPOSE: The healing process following tooth extraction apparently results in a pronounced resorption of the alveolar ridge. As a result, the width of alveolar ridge is reduced and severe alveolar bone resorption occurs. The purpose of this experiment is to clinically and histologically evaluate the results of using horse-derived bone mineral for socket preservation. METHODS: The study comprised 4 patients who were scheduled for extraction as a consequence of severe chronic periodontitis or apical lesion. The extraction was followed by socket preservation using horse-derived bone minerals. Clinical parameters included buccal-palatal width, mid-buccal crest height, and mid-palatal crest height. A histologic examination was conducted. RESULTS: The surgical sites healed uneventfully. The mean ridge width was 7.75 +/- 2.75 mm at baseline and 7.00 +/- 2.45 mm at 6 months. The ridge width exhibited no significant difference between baseline and 6 months. The mean buccal crest height at baseline was 7.5 +/- 5.20 mm, and at 6 months, 3.50 +/- 0.58 mm. The mean palatal crest height at baseline was 7.75 +/- 3.10 mm, and at 6 months, 5.00 +/- 0.82 mm. There were no significant differences between baseline and 6 months regarding buccal and palatal crest heights. The amount of newly formed bone was 9.88 +/- 2.90%, the amount of graft particles was 42.62 +/- 6.57%, and the amount of soft tissue was 47.50 +/- 9.28%. CONCLUSIONS: Socket preservation using horse-derived bone mineral can effectively maintain ridge dimensions following tooth extraction and can promote new bone formation through osteoconductive activities.
