不同桩核修复磨牙的生物相容性比较

摘要

背景：磨牙是主要的功能牙齿，磨牙的修复应能改善其生物功能和具有坚固的组织学效果。目的：评价不同桩核材料在磨牙修复中的应用效果。方法：对应用银汞桩核、铸造桩核和纤维桩核修复磨牙缺损的患者进行随访观察，检查修复体松动、折断、脱落以及牙周炎和牙龈炎等发生情况，X 射线检查桩核冠修复体与牙体间的结合情况以及根管折断情况和根尖根周牙槽骨吸收情况，评价不同桩核材料修复磨牙的生物相容性并进行比较。结果与结论：银汞桩核、铸造桩核和纤维桩核修复磨牙均可以获得较好的治疗效果，但是，与铸造桩核相比较，银汞桩核和纤维桩核的生物性能更好，修复体松动、折断和脱落的发生率更低，根尖根周等炎性并发症的发生率也更低，并且组织学坚固效果更好，是磨牙修复中首选的桩核材料。%BACKGROUND: Molars are the main functional teeth, and molar repairing is able to improve the biological function of molars and has the sturdy histological effect. OBJECTIVE: To evaluate the application effect of different post-core materials in molar repairing. METHODS: The patients received molar repairing with amalgam post-core, cast post-core and fiber post-core were fol owed-up to observe the incidence of prosthesis loosening, fracture, loss, periodontitis and gingivitis. The combination between post-core crown prosthesis and dental body, broken root canal and the resorption of alveolar bone of root tip and root body were tested with X-ray film. The biocompatibility of different post-core materials used for molar repairing was evaluated and compared.RESULTS AND CONCLUSION: The amalgam post-core, cast post-core and fiber post-core have good effects for the repair of molars. But compared with cast post-core, the amalgam post-core and fiber post-core have better biocompatibility, lower incidence of prosthesis loosening, fracture, loss, periodontitis and gingivitis, and have better histological effect, considered as the best post-core materials for molar repairing.
