To present two successful cases involving management of endodontic-periodontal combined lesions with root resection and guided tissue regeneration (GTR) therapy.
Mesiobuccal resection surgery was performed concomitant with GTR therapy to manage endodontic-periodontal combined lesions on teeth 17 and 26. The increased mobility after the periodontal surgery gradually decreased during the healing period. At 15 and 20 month follow-ups, respectively, the teeth showed no mobility, 2-3 mm pocket depths and no further bone loss.
Treatment of periodontally involved maxillary teeth creates unique challenges, given the presence of furcations, root proximities and the maxillary sinus. Root resection combined with GTR therapy can enable tooth maintenance with a good long-term prognosis.
介绍 2 例采用根管切除和引导组织再生（GTR）治疗术成功治疗牙周-牙髓联合病变的病例。
对 17 号牙和 26 号牙的牙周-牙髓联合病变进行了近中颊侧切除术联合 GTR 治疗。牙周手术后牙齿的松动度逐渐降低，在愈合期内逐渐恢复。15 个月和 20 个月随访时，牙齿无松动，探诊深度 2-3mm，无进一步的骨丧失。
上颌牙周病涉及的牙齿由于存在分叉、根近中面和上颌窦等因素，治疗具有独特的挑战。根管切除联合 GTR 治疗术可保留牙齿，具有良好的长期预后。
