Development and clinical application of new orthodontic miniscrew implant system using bioabsorbable material combined with bone morphogenetic protein

本研究的目的是利用生物可吸收材料结合骨形态发生蛋白研制一种新型的正畸微螺钉种植系统，在种植部位使用脱钙牙基质，脱钙牙基质促进新骨形成，并在此基础上，本研究利用支架制造技术建立了一个种植体植入系统，这些结果表明，种植体系统用于正畸治疗的建筑可能性植入一个生物可吸收和生物相容的植入物。

The aim of this study is to development new orthodontic miniscrew implant system using bioabsorbable material combined with bone morphogenetic protein.For the implanted site, demineralized tooth matrix was used.Then, the ability of new bone formation was accelerated by demineralized tooth matrix.Furthermore, an implant placement system was established using stent fablication.These results suggested that architectural likelihood of an implant system for orthodontic treatment with a bioabsorbable and biocompatible implant.
