【摘要】：背景:磨牙具多根、多根管、多方向、不同几何形态及分布等特点,以单根管牙桩核理论指导磨牙临床修复,磨牙牙根将因桩道制备过度而极易并发侧穿或根折,因此有必要对纤维桩-树脂核的磨牙修复设计进行进一步的研究和探讨。目的:评价不同桩数设计纤维桩-树脂核修复磨牙残根残冠的临床疗效。方法:选择48例54颗根充完善的人磨牙残根残冠,进行不同桩数的纤维桩-树脂核与全冠修复,其中单根纤维桩核修复17例20颗,双根纤维桩核修复16例18颗,3根纤维桩核修复15例16颗。随访观察24个月,比较修复效果。结果与结论:随访24个月,单根纤维桩组、双根纤维桩组、3根纤维桩组修复成功率分别为85%、94%、94%,3组间修复成功率比较差异无显著性意义;修复失败的5例中,单根纤维桩组发生纤维桩脱落3例,双根纤维桩组纤维桩脱落1例,3根纤维桩组纤维桩折断1例,均未发生根折。3种桩数设计的纤维桩-树脂核修复磨牙残根残冠均能获得较好的短期临床效果,没有因为桩的数目不同而降低修复效果。
[Abstract]:Background: molars have the characteristics of multi-root, multi-root canal, multi-direction, different geometry and distribution. The single root canal post core theory is used to guide the clinical restoration of molars. Therefore, it is necessary to further study and discuss the design of fiber-post-resin core molar restoration. Objective: to evaluate the clinical effect of the restoration of residual root and crown of molars with different pile number design fiber-resin core. Methods: a total of 54 residual crowns of 48 human molars with complete root filling were selected for the restoration of fiber pile-resin core and full crown with different numbers of piles. Among them, 17 cases (20 cases) were repaired with single fiber post core. 16 cases (18 cases) were repaired with double fiber post core, and 16 cases (15 cases) were repaired with 3 fibers. All patients were followed up for 24 months to compare the effect of repair. Results and conclusion: after 24 months follow-up, there was no significant difference in the success rate of repair among the three groups of single fiber pile group, double fiber pile group and double fiber pile group, and there was no significant difference in the success rate of repair between the three groups. Fiber pile shedding occurred in 3 cases in single fiber pile group, 1 case in double fiber pile group and 1 case in 3 fiber pile group. The restoration of residual root and crown of molars with fibrous pile-resin core without root fracture of 3 kinds of piles could obtain good short-term clinical effect, and the effect of restoration was not reduced because of the different number of piles.
