摘要: 目的    比较3种材料髓超嵌体修复根管治疗后磨牙的临床效果。方法    选取2018年9月至2020年8月在泰州职业技术学院口腔门诊部就诊的磨牙根管治疗后牙体缺损患者88例(患牙90颗),随机分为陶瓷组(IPS e.max CAD玻璃陶瓷嵌体修复,30例)、聚合瓷组(Ceramage聚合瓷嵌体修复,28例)和钛合金组(钛合金嵌体修复,30例),每组患牙各30颗。参照改良的美国公共卫生署标准,对3组嵌体修复后36个月的边缘密合性、修复体表面情况、继发龋、对颌牙磨耗、色泽协调性及邻接关系进行评价。比较3组各评价项目分级为优秀的嵌体占比差异及患者满意情况分布差异。结果    修复后36个月,3组各评价项目分级为优秀的占比均≥ 80%;3组在修复体表面情况和对颌牙磨耗项目分级为优秀的占比差异均有统计学意义(均P < 0.05);进一步组间两两比较发现,钛合金组修复体表面情况分级为优秀的占比明显高于陶瓷组和聚合瓷组,对颌牙磨耗分级为优秀的占比明显低于陶瓷组和聚合瓷组,差异均有统计学意义(均P < 0.05)。陶瓷组患者24例满意,6例不满意;聚合瓷组患者23例满意,5例不满意;钛合金组患者24例满意,6例不满意;3组患者满意情况分布比较,差异无统计学意义(χ2 = 0.056,P = 0.972)。结论    3种嵌体材料修复磨牙牙体缺损效果均较理想,且钛合金嵌体在修复体表面情况方面的修复效果优于Ceramage聚合瓷嵌体和IPS e.max CAD玻璃陶瓷嵌体,更适合咬合紧、力大的患者,但其在对颌牙磨耗方面不及其他2种嵌体。

Abstract: Objective    To compare the clinical effects of three different endo-overlay materials in repairing molar tooth defects. Methods    Totally 88 patients(90 teeth)with dental defects after root canal treatment for molars at Oral Clinic of Taizhou Polytechnic College from September 2018 to August 2020 were selected and randomly divided into ceramic group(repaired with IPS e.max CAD glass ceramic inlay,30 cases),polymer ceramic group(with Ceramage polymer ceramic inlay,28 cases),and titanium alloy group(with titanium alloy inlay,30 cases),and there were 30 defective teeth in each group. According to the modified United States Public Health Service(USPHS)standards,the following items were evaluated in the three groups at 36 months after repair: the marginal sealability,surface conditions of the prothesis,secondary caries,wearing of opposite teeth,color consistency,and adjacent relationship. The differences in the proportion of each evaluation item graded as excellent and the patients′satisfaction among the three groups were compared. Results    At 36 months after restoration,the proportion of each evaluation item graded as excellent in all three groups was ≥ 80%;there was a statistically significant difference in the proportion of inlays graded as excellent in terms of surface condition of the prothesis and wearing of opposite teeth among the three groups(all P < 0.05);further pairwise comparison revealed that the proportion of inlays with excellent grading on surface condition in titanium alloy group was significantly higher than that in ceramic group and polymer ceramic group, while the proportion of inlays with excellent grading on the wearing of opposite teeth was significantly lower than that in ceramic group and polymer ceramic group,and the differences were statistically significant(both P < 0.05). It was also found that 24 patients in ceramic group were satisfied,while 6 were not satisfied;23 cases in polymer ceramic group were satisfied,while 5 cases were not;24 patients in titanium alloy group were satisfied,while 6 were not. The distribution of satisfaction among the three groups of patients was compared,and the difference was not statistically significant(χ2 = 0.056,P = 0.972). Conclusion  The three types of inlay materials in this study have all achieved ideal results in repairing molar tooth defects. Moreover,titanium alloy inlays have better repairing effects on the surface conditions than Ceramage polymer ceramic inlays and IPS e.max CAD glass ceramic inlays,making them more suitable for patients with tight occlusion and high occlusal force. However,they are not as good as the other two types of inlays when it comes to the wearing of opposite teeth.
