摘要：
Alveolar ridge preservation has become a very common procedure following tooth extraction. This study presents a clinical, histologic, and histomorphometric analysis of postextraction bone changes using nanocrystalline hydroxyapatite (nc-HA) and exposed high-density polytetrafluoroethylene (d-PTFE) membrane. A total of 10 extraction sockets were treated. Clinical measurements were taken after tooth extraction with a customized acrylic stent to ensure the same measurement points. At 6 months, clinical measurements were repeated and bone specimens taken. An overall bone reduction was observed. The histologic and histomorphometric analysis revealed newly formed bone (25.92% +/- 18.78%), soft tissue (28.55% +/- 9.73%), and residual graft particles (15.43% +/- 11.08%). Further studies are necessary to evaluate the efficacy of this technique over the long term. Int J Periodontics Restorative Dent 2017; 37: 283-290.
