目的探讨髓室底穿孔的下颌磨牙残冠经完善的根管治疗后的保存治疗方法。方法随机选择临床建议拔除的髓室底穿孔的下颌磨牙残冠95例,经完善的根管治疗后15—30天无症状者,于髓室底穿孔的根分叉处将牙冠切成近、远中两段,桩核修复并修改成两个前磨牙形态,联冠修复。结果修复后5年复查,总有效率87.7%,患牙能正常行使咀嚼功能使咀嚼功能。结论髓室底穿孔的下颌磨牙残冠,经完善的根管治疗后,于根分又处行冠切,并行桩核联冠修复,疗效较好,患牙可以长时间保存并能行使咀嚼功能。
Objective To investigate the restorative procedure and the survival period of the mandibular poste riorresidual crown companied with penetrate dpulp floor after complet eendodontie treatment, Method 95 patients (113teeth) with penetrated pulp floor of mandibular posterior residual crowns were selected at random .All the cases were followed up from half a month to a month after excellent root canal therapy and without any uncomfortable symptom. Then,these mandibular residual teeth were separated into medial part and distalone along the root furcation, and modified each part in 2 to the shape of premolar by post/core crown, meanwhile the two post/core crowns of each posterior residual tooth were repaired by combination casting crowns.Result All the patients were followed up for five years after prostheties treatment .It was found that the valid rate was87.7%, and these teeth can performed theirmormal function.Conclusion This treatment may be employed as a practical means for the mandibular posterior residual crown with penetrated pulp floor.
