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。
OBJECTIVE: To analyze the clinical effect of repairing the defect molars with the medullary crest made of porcelain or polymeric porcelain. Methods: Sixty patients with molars defect were selected as the research object and randomly divided into control group and observation group. In the control group, cast-porcelain material was used to make the crown of the medullary cavity, and the observation group was made with the polymer porcelain to make the crown of the medullary cavity. The clinical therapeutic effects and aesthetics of the two groups were observed and compared. Results: The clinical excellent rate was 96.67% in the observation group and 76.67% in the control group. The difference between the two groups was statistically significant (P <0.05). The one-year marginal adhesion of the observation group was 96.67%, while the control group was 80.00%, the difference between the two groups was statistically significant (P <0.05). The 2-year marginal adherence observation group was 93.33%, while the control group was 73.33%. The difference between the two groups was statistically significant (P <0.05). In the observation group, the satisfaction rate of clinical treatment was 96.67%, while that of the control group was 73.33%. The difference between the two groups was statistically significant (P <0.05). The incidence of adverse reactions in the observation group was 3.33% and in the control group was 20.00%, the difference between the two groups was statistically significant (P <0.05). CONCLUSION: In the repair of molar defects, the medullary crown retention made of polymer porcelain can improve the excellent rate of treatment, the chewing function of the patients, the good periodontal condition, the high satisfaction of the patients and the better overall treatment effect .
