Oral hygiene in furcation defects of upper molars is difficult to achieve. In this case report, a combined surgical and orthodontic treatment procedure is presented to facilitate access and plaque control in furcation areas of upper molars with class-III furcation defects. After endodontic treatment and root resection in an upper 1st molar, the remaining mesiobuccal and palatal roots were separated and aligned orthodontically within the dental arch, as one-rooted teeth. The new morphological position of the roots greatly facilitated oral hygiene and may offer a better long-term prognosis.
上颌磨牙根分叉病变的口腔卫生难以维持。在本病例报告中，介绍了一种外科手术与正畸治疗相结合的方法，以利于对上颌磨牙Ⅲ度根分叉病变区域进行清洁和控制菌斑。对上颌第一磨牙进行根管治疗和牙根切除术之后，将剩余的近中颊根和腭根分开，并作为单根牙在牙弓内进行正畸排齐。牙根新的形态位置极大地促进了口腔卫生，并可能带来更好的长期预后。
