有预备瓷贴面和无预备瓷贴面的修复效果对比

Comparison of repair effect between prepared porcelain veneerand no prepared porcelain veneer

目的:研究有预备瓷贴面和无预备瓷贴面的修复效果。方法:选取2014年～2016年接收的利用瓷贴面进行牙齿修复患者40例,平均分为两组,有预备组20例,采取有预备瓷贴面治疗,无预备组20例,采取无预备瓷贴面治疗。结果:术后对所有患者进行2年的随访,两组患者牙齿存留率差异无统计学意义(P> 0. 05)。有预备组患者术前的紧张程度明显高于无预备组,差异具有统计学意义(P <0. 05)。两组患者术后龈沟出血指数对比差异无统计学意义(P> 0. 05)。两组患者在颜色匹配、牙龈反应和边缘染色方面的差异无统计学意义(P> 0. 05),有预备组患者的牙齿边缘适合性优于无预备组,牙敏感率高于无预备组,差异具有统计学意义(P <0. 05)。结论:在对接受瓷贴面牙齿修复的患者进行治疗时,采取有预备瓷贴面和无预备瓷贴面均能够取得理想的治疗效果,但是无预备组患者接受治疗时的紧张程度较低,接受程度比较高,有预备组的边缘适合性更好,治疗过程中需要根据患者的具体情况选择合适的治疗方式。

Objective to study the repair effect of prepared porcelain veneer and no prepared porcelain veneer.Method 40 patients who received porcelain veneer for tooth restoration in our hospital from 2014 to 2016 were selected,they were divided into two groups on average,20 patients in the prepared group received porcelain veneer treatment,and 20 patients in the unprepared group received porcelain veneer treatment.Results All patients were followed up for 2 years after surgery,and there was no statistically significant difference in tooth retention rate between the two groups(P >0.05).The preoperative tension of the patients in the preparatory group was significantly higher than that in the non-preparatory group,and the difference was statistically significant(P<0.05).There was no statistically significant difference in gingival sulcus bleeding index between the two groups(P >0.05).There was no statistically significant difference between the two groups in color matching,gingival response and edge staining(P >0.05).The tooth edge fitness of patients in the prepared group was better than that in the unprepared group,and the tooth sensitivity rate was higher than that in the unprepared group,and the difference was statistically significant(P<0.05).Conclusion In treating in patients undergoing porcelain cover dental restoration,prepare to have porcelain veneers and extemporaneous porcelain veneers are able to obtain ideal treatment effect,but there is no preparation group of patients treated at low stress levels,accept degree is higher,with the edge of the reserve team fit better,according to the treatment process to the patient’s specific situation to choose the appropriate treatment.
