玻璃纤维桩核与铸造钯银金属桩核修复残根、残冠的疗效比较

摘要

Objective The observation of the clinical effects of glassfiber-reinforced composit post and core in the restoration of residual crowns and residual roots joint full crown restoration with palladium silver and Palladium silver casting metal post and core joint full crown restoration with palladium silver metal. Methods A total of 112 teeth from 68 patients in The First Affiliated Hospital of Xinjiang Medical University,were treated with root canal therapies,afterwards,accordingto the different situationsof patients,restored by glass fiber core and crowns(36 patients,58 teeth)or palladium silver metal post and core(32 patients,54 teeth).All patients were visited for 2 years as follow-up. Results Glass fiber post and core groups treatment success rate was 89.7%,52 teeth were success,6 teeth were failed.Palladium silver metal post and core groups treatment success rate was 87.0%,47 teeth were success,7 teeth were failed,including of 3 root fractured.The success ratio of these two groups statistically was no significance(P>0.05). Conclusion The root canal therapy of residual roots and residual crowns repair treatment has taken relatively under perfect condition of standard procedure and guidance,whether it is glass fiber post and core or palladium silver metal post and core,have a higher survival rate over 2 years of observation period.But the incidence of root fracture is Higher in palladium silver Metal post restoration,so clinically need more attention.That glass fiber post repair effect has certain advantages compared to the palladium silver metal post,use of high value.%目的：观察评估残冠、残根使用玻璃纤维树脂桩核联合钯银烤瓷冠修复与铸造钯银金属桩核联合钯银烤瓷冠修复的临床效果。方法：选用新疆医科大学第一附属医院口腔科就诊患者68例，共112颗患牙为分析目标，在根管治疗后参考牙齿的基本条件，选取玻璃纤维树脂桩核或铸造钯银金属桩核修复后联合用钯银烤瓷冠固定修复，并分为玻璃纤维桩核组（36例，58颗牙）和钯银金属桩核组（32例，54颗牙）等两组后进行统计分析。约为2年的随访，对比两组患者的临床疗效。结果：玻璃纤维桩组修复后成功52颗，失败6颗，无根折，治疗成功率89.7%；钯银金属桩组修复后成功47颗，失败7颗，其中根折3颗，治疗成功率87.0%，两组成功率比较，差异无统计学意义(P＞0.05)。结论：在根管治疗采用标准的流程指导和技术规范的情况下，如果疗效和实施质量都达到比较高的要求，那么玻璃纤维桩修复和钯银金属桩核修复都可以在2年的随访期间内保留较高的存活率，但是钯银金属桩核修复后发生根折概率较大，临床上需要重视。这说明玻璃纤维桩核修复效果跟钯银金属桩核相比有一定的优势，具有良好的使用价值。
