目的探讨钴铬合金铸造桩核和ever Stick纤维桩在唇、舌向倾斜上颌中切牙改向修复中的临床疗效。方法 60例唇、舌向倾斜上颌中切牙患者,随机分为观察组和对照组,各30例。两组患者均采用改向桩核冠修复术进行治疗,对照组患者使用钴铬合金进行修复,观察组患者采用ever Stick纤维桩修复,治疗1年后对治疗效果进行调查,观察两组患者治疗后是否出现牙根断裂、桩核断裂、桩核松动护或脱落等情况。结果修复治疗6、12个月后对两组患者进行复诊,观察组患者修复成功率分别为100.00%、93.33%,对照组患者修复成功率分别为93.33%、73.33%,两组患者治疗6、12个月后修复成功率比较差异均有统计学意义(P<0.05)。结论使用ever Stick纤维桩对唇、舌向倾斜上颌中切牙患者患牙进行修复,效果较好,出现牙根断裂、桩核松动、脱落、变色的情况较少,更有利于牙齿的保存。
Objective To investigate the clinical effect of casting cobalt-chromium cast post and ever Stick fiber posts on the reorientation of the maxillary central incisor with lip and lingual tilt. Methods Sixty cases of maxillary central incisor with lip and tongue tilt were randomly divided into observation group and control group, with 30 cases in each group. Patients in both groups were treated with cobalt-chromium alloy. The patients in the observation group were cured with the ever-Stick fiber post. After 1 year of treatment, the treatment effect was investigated and the treatment of two groups of patients was observed After the occurrence of root fracture, pile core break, pile loose or fall off and so on. Results After 6 and 12 months of treatment, the two groups of patients were referred for follow-up. The success rate of repair in observation group was 100.00% and 93.33% respectively. The success rate of repair in control group was 93.33% and 73.33% After 12 months, the success rate of repair was significantly different (P <0.05). Conclusion The use of the ever-Stick fiber post to repair the affected teeth in patients with lip and lingual tilt maxillary central incisors has a good effect. There are fewer cases of tooth root fracture, loose and detached stems, discoloration and more conducive to the preservation of teeth.
