摘要:

目的探讨纵折磨牙采用内固定后全冠修复的临床效果。方法对38 例患者的纵折磨牙采用钢丝外结扎后根管治疗,然后内固定和流动树脂充填,最后进行全冠修复,观察不同牙位、不同折裂方向和不同就诊时间纵折磨牙的临床保存疗效。结果上下颌纵折磨牙保存成功率有明显差异。结论纵折磨牙的临床保存效果不仅与裂隙封闭效果、劈裂牙体复位和固定程度以及就诊时间等有关,而且与纵折磨牙的牙位和折裂方向明显相关,伴牙根损伤的纵折磨牙临床保存疗效不理想。

关键词: 磨牙纵折, 内固定, 折裂方向

Abstract:

Objective To observe the therapeutic results of complete coronal restoration after internal fixation conducted over the fractured molars. Methods 38 cases of molar vertical fractures were subjected to root canal therapy after outer steel wire ligation had been done, following which internal fixation and fluid resin infilling were both conducted, and finally, completed coronal restoration was made in the hope of finding out the clinical healing efficacy in contrast with the factors like molar position, the fracture direction, and the time of clinical treatment. Results Clear difference of success ratio observed between the restoration of the upper and lower molar fractures. Conclusion Not only factors like the closeness of crack, the reset position of the split molars, the tightness of fixation and time of clinical treatment, but also the position of the molar fracture and the direction of the crack line as well exert a significant influence upon the restoration effects, and molar vertical fractures with injury have bad results.

Key words: molar vertical fracture, internal fixation, direction of the fracture
