用脱钙胎儿骨移植治疗牙周炎病人３９例，７８颗牙齿的临床观察，并且与自体对侧同名牙为对照组对比，手术后牙龈指数（ＧＩ）、牙周炎指数（ＰＤＩ）及牙槽骨再生等方面差异有非常显著性，观察１年，效果良好，总有效率，观察组为９７．４４％，对照组为８２．０５％差异有显著性。结果表明同种异体移植，通过爬行替代，诱导新骨形成及重建牙周组织的理论是成立的。并且也为牙周炎的手术治疗提供了理论依据。
39 cases of periodontitis patients treated with decalcified fetus bone grafts and 78 teeth were observed and compared with the control group with the same name of contralateral autologous contralateral gingival index (GI), periodontitis index (PDI) and teeth Bone regeneration and other aspects of the difference is very significant, observed 1 year, the effect is good, the total efficiency, the observation group was 97.44%, the control group was 82.05% difference was significant. The results suggest that the theory of allograft transplantation, replacement by creeping, induction of new bone formation, and reconstruction of periodontal tissue is established. And also provide a theoretical basis for the surgical treatment of periodontitis.
