不同材料制作髓腔固位冠修复缺损磨牙的临床对比研究

目的：分析铸瓷或聚合瓷制作的髓腔固位冠修复缺损磨牙的临床应用效果。方法：选择磨牙缺损患者60例作为研究对象，随机平均分为对照组和观察组。对照组采用铸瓷材料制作髓腔固位冠，观察组采用聚合瓷制作髓腔固位冠，针对两组患者的临床治疗效果、美观性等指标进行观察比较。结果：观察组临床优良率为96?67％，对照组优良率为76．67％，两组差异具有统计学意义（P＜0．05）。修复1年边缘密合度观察组为96．67％，对照组为80．00％，两组差异具有统计学意义（P＜0．05）。修复2年边缘密合度观察组为93．33％，对照组为73．33％，两组差异具有统计学意义（P＜0．05）。观察组患者的临床治疗效果满意度96．67％，对照组73．33％，两组差异具有统计学意义（P＜0．05）。观察组患者的不良反应发生率3．33％，对照组20．00％，两组差异具有统计学意义（P＜0．05）。结论：在磨牙缺损的修复治疗中，聚合瓷制作的髓腔固位冠修复，可以提高治疗的优良率，患者的咀嚼功能、牙周情况良好，患者的满意度较高，整体治疗效果较好。

Different materials of endocrowns repair defects molar clinical application research

Objective:To research different materials of endocrowns repair defects molar clinical application. Meth?ods:Randomly selected during December 2011 to February 2013,our hospital molars defect in patients with 60 cases,as the research object,its averaged were divided into control group and observation group. Control group implemented casting porce?lain material pulp cavity retainer treatment,observation group implemented polymerization of porcelain material pulp cavity retainer for treatment,according to clinical therapeutic effects of two groups of patients,promote the frequency,the beautiful sex index were observed and compared. Results:In this study,the observation group of patients in the treatment of fine rate was 96. 67%,control group patients was 76?67%. There was statistical significance(P<0. 05). In observation group of pa?tients edge fit 1 year was 96?67%,the control group was 80. 00%. There was statistical significance(P<0. 05). In observa?tion group 2 years marginal fit as 93. 33%,the control group was 73. 33%. There was statistical significance(P<0. 05). In observe group the clinical therapeutic effect of patients? satisfaction was 96. 67%,the control group was 73. 33%. There was statistical significance(P<0. 05). In observation group of patients the incidence of adverse reactions was 3?33%,the control group was 20. 00%. There was statistical significance(P<0. 05). Conclusion:In the treatment of molar teeth defect,of the medullary cavity of the polymerization ceramic materials for the retainer crown restoration treatment,can improve the treat?ment of patients with crop,chewing function,in patients with periodontal condition is good,and patient satisfaction is higher, and to the overall treatment effect is good.
