Summary

This study is mainly targeted affected teeth which could not be retained, and patients are willing to undergo implant repair at the later stage. After teeth extraction, Geistlich Bio-Oss ® Particles or Bio-Oss ® Collagen are immediately implanted in the teeth extraction socket and covered with Bio-Gide ® collagen membrane for site preservation.Through postoperative follow-up, postoperative clinical and imaging objective indicators, combined with the subjective evaluation of surgeons and patients, and compared with conventional extraction treatment method, the study is aimed to evaluate the effectiveness of different site preservation of alveolar crest preservation, in order to reduce the alveolar bone width and height loss, effectively reduce alveolar bone absorption, or even achieve bone incrementation, thus to get the ideal site preservation effect, to improve the oral implant success rate, improve implant aesthetic score and patient satisfaction, provide more clinical standard reference of the clinical application of site preservation.
