目的分析金瓷修复体崩瓷原因及效果。方法将金瓷修复体崩瓷患者64例根据治疗方法不同分为观察组34例和对照组30例。对照组行传统修复方法,观察组行保留金属底冠修补方法,对比2组患者修复情况及再次崩瓷率。结果 2组患者一次修复成功率、修复牙齿外形良好率及患者治疗满意率均差异无统计学意义(P>0.05)。观察组修复时间为(1.1±0.5)h显著短于对照组的(3.6±1.2)h,差异均有统计学意义(P<0.05)。经6个月随访观察组再次崩瓷率为2.9%(1/34),对照组再次崩瓷率为3.3%(1/30),2组患者再次崩瓷率比较差异无统计学意义(P>0.05)。结论金瓷修复体崩瓷由多方面原因造成,采用合理的保留金属底冠修补方法可取得显著修复效果,同时可使修复时间大幅缩短,再次崩瓷率较低,值得在临床中推广。
Objective To analyze the reason and effect of porcelain restoration porcelain collapse. Methods Sixty-four patients with porcelain restoration porcelain were divided into observation group (34 cases) and control group (30 cases) according to different treatment methods. Control group traditional repair methods, the observation group to retain the metal crown at the end of repair methods, compared with two groups of patients and the situation once again collapse collapse rate. Results There was no significant difference between the two groups in the success rate of primary repair, the good rate of dental restoration and the satisfactory rate of patients’ treatment (P> 0.05). The repair time of the observation group was (1.1 ± 0.5) h significantly shorter than that of the control group (3.6 ± 1.2) h, the difference was statistically significant (P <0.05). In the 6-month follow-up observation group, the rate of disintegration was 2.9% (1/34) in the observation group and 3.3% (1/30) in the control group, and there was no significant difference between the two groups > 0.05). Conclusion The porcelain restoration porcelain collapse caused by many reasons, the use of reasonable retention of the metal crown repair method can be significantly repaired, but also can make the repair time is significantly shortened once again the collapse of the porcelain rate is low, it is worth promoting in the clinic.
