摘要

臨床上，成功地治療有根叉侵犯的大臼齒是一大桃戰，過去五十年間，利用牙根切除術治療較嚴重的垂直骨性缺陷及牙根叉病變，保留嚴重牙周病患的牙齒，對減少病人提早戴活動假牙，的確有很大幫助。但是，要注意牙根切除後的牙齒，需要牙周、根管、贗復及病人各方面的配合，術前仔細地評估，術後定期維護，才能有較高的成功率。今日，牙科植體的進步，已經改變牙周及贗復的治療選擇，當面臨留下牙齒或拔牙做單顆植體時，須就牙齒情況、骨質條件、經濟因素、病人整體考量，才能維持長期成功。

Successful treatment of furcated molar teeth presents the periodontist and prosthodontist with a challenging dilemma. Root resection had been applied in dentistry for treatment of selected furcated molar teeth over 50 years. Unfortunately, the literature reveals a significant disparity in the long-term prognosis of root resection therapy as reported by different clinicians. The technique of root resection is dependent on a high level of expertise in all applicable disciplines - periodontal, endodontic and restorative - as well as on competent oral hygiene by the patient. There is no question that the acceptance of osseointegrated dental implants has altered periodontal & prosthodontic treatment options. However, there are limited retrospective studies of single implants placed and functioning as independent restorations. Thoughtful decision-making is important as patents seek professional advice on retaining their teeth or replacing them with implants. The decision to place an implant is not based solely on anatomical sited but on the patient as a whole. Treatment is predicted on diagnosis, and root resection are one of the viable choices.
