目的:前牙牙折为临床常见病,对前牙牙折患者用不同根管桩进行自体牙一次性修复后比较其修复效果。方法:将前牙牙折者按照治疗方法分为观察组和对照组,对照组采用成品螺纹桩进行一次性自体牙修复,观察组采用玻璃纤维桩进行一次性自体牙修复,统计修复失败的原因与例数,包括冠桩的脱位、冠折、根折等。结果:对照组中有6例修复失败,观察组中只有1例修复失败。结论:在前牙牙折采用自体牙一次性修复时,两组患者修复效果均较满意,考虑到长期临床效果和桩的生物机械性能差异,观察组效果优于对照组(P<0.05)。
OBJECTIVE: Anterior teeth fold is a common clinical disease, and its repair effect is compared with the one-off repair of the self-root teeth of the anterior teeth tooth-bending patients with different root canal piles. Methods: Tooth fractures of anterior teeth were divided into observation group and control group according to the treatment methods. The control group was treated with finished screw pile for one-time self-repaired teeth. The observation group was treated with glass fiber post for one-time self-repaired teeth. The number of cases, including crown pile dislocation, crown fracture, root fracture and so on. Results: Six patients in the control group failed to repair, and only one patient in the observation group failed to repair. CONCLUSION: When the one-off restoration of the anterior teeth is performed with one-off self-contained teeth, the repair effect of both groups is satisfactory. Considering the long-term clinical results and the difference of the biomechanical properties of the pile, the observation group is better than the control group (P <0.05).
