牙体缺损修复中玻璃纤维桩与铸造金属桩的应用价值

背景：有研究显示，利用纤维桩修复大面积牙体缺损，在预后如桩核冠脱落、桩核折断、根折等方面明显优于铸造金属桩。目的：分析玻璃纤维桩与铸造金属桩修复牙体缺损的效果。方法：选择牙体缺损修复患者100例（150颗牙），其中男51例，女49例，随机分为观察组（50例，70颗牙）和对照组（50例，80颗牙），分别给予玻璃纤维桩修复和铸造金属桩修复。修复后随访1-3年，观察两组修复体完整度、颜色匹配情况、边缘适合性、牙周袋深度、碱性磷酸酶及桩核冠损坏情况。结果与结论：修复1年后，观察组修复体边缘适合性及颜色匹配方面显著优于对照组（P均〈0.05）；观察组修复后1，3年碱性磷酸酶水平低于对照组（P 〈0.05），两组牙周探诊深度比较差异无显著性意义；观察组修复成功率高于对照组（P〈0.05）。结果表明与铸造金属桩修复比较，玻璃纤维桩修复牙体缺损可获得良好的修复效果及远期修复成功率，有利于维持良好的牙周健康水平。

Application values of glass fiber post and cast metal post in the repair of dental defects

BACKGROUND：Studies have shown that fiber post is superior to cast metal post in the restoration of large-area dental defects, in prognostic terms of post and core crown off, post and core breakage, root fracture. OBJECTIVE：To explore the application value of glass fiber post and cast metal post in restoration of tooth defects. METHODS：Totaly 100 patients with dental defects （150 teeth; 51 males and 48 females） were selected and randomly divided into observation group （50 cases, 70 teeth） and control group （50 cases, 80 teeth）. Al of the patients were treated with glass fiber post and metal post repair. After repair, al the patients were folowed up for 1-3 years. The repair effect of the two groups were observed and compared in terms of integrity, color matching, marginal fit, periodontal pocket depth, alkaline phosphatase activity and post and core crown damage. RESULTS AND CONCLUSION：After 1 year of repair, the observation group was better than the control group in aspects of marginal fit and color matching （P 〈 0.05）; after 1-3 years, the alkaline phosphatase activity was significantly lower in the observation group than the control group （P 〈 0.05）, and there was no difference in the periodontal probing depth between the two groups; while the observation group exhibited higher successful rate than the control group （P 〈 0.05）. The results show that compared with the cast metal post, glass fiber post is better for restoration of tooth defects, exhibiting better restoration effect and long-term success rate, which is conducive to the maintenance of periodontal health.
