Thirty-two consecutively treated patients were included in this study of 49 root-resected molars that were under regular recall of 3 to 6 months for a mean of 11.5 years (2 to 23 years). Treatment modalities for all patients were very similar. Endodontic treatment was conservatively performed prior to resection with maximum preservation of tooth structure. No threaded posts were used. Provisional restorations were in place prior to periodontal therapy (pocket reduction with or without osseous surgery). Most patients were treated with complete-mouth reconstructions. Ninety-two percent of all resected molars survived an average of 12 years. Teeth failed because of recurrent caries or for endodontic and strategic reasons. If proper treatment is rendered periodontically involved molars can be maintained for a long period of time and serve successfully as abutments in complete-mouth restorations. Great care must be taken throughout the whole process of case selection, reevaluation, and endodontic, periodontal, restorative, and maintenance therapies.
本研究纳入了32例连续接受治疗的患者，共49颗经牙根切除的磨牙，这些磨牙每3至6个月定期复查，平均复查时间为11.5年（2至23年）。所有患者的治疗方式非常相似。在牙根切除术前进行保守的牙髓治疗，最大限度地保留牙体结构。未使用螺纹桩。在牙周治疗（有或无骨手术的袋深减少）之前进行临时修复。大多数患者接受了全口重建治疗。所有切除磨牙中有92%平均存活了12年。牙齿因复发性龋齿或牙髓及策略性原因而失败。如果进行适当的治疗，牙周受累的磨牙可以长期保留，并成功地作为全口修复中的基牙。在病例选择、重新评估以及牙髓、牙周、修复和维护治疗的整个过程中都必须格外小心。
