Abstract

The result of surgical repositioning of 12 unerupted anterior teeth was studied. The unerupted teeth were gently exposed, gradually repositioned by shifting them bodily toward the occlusal plane without disturbing the periodontal ligament, and splinted for 3 wk. Root canal therapy was performed at the end of the second week following repositioning. Obturation was done at the end of the third week just before splint removal. Clinical and radiographic examination (follow-up period: 6 months to 3.5 yr) revealed no root resorption with satisfactory apical healing and healthy supporting tissues.

摘要

对12颗未萌出的前牙进行手术复位的结果进行了研究。将未萌出的牙齿小心暴露，通过将其整体向咬合平面移动而逐渐复位，同时不干扰牙周韧带，然后用夹板固定3周。在复位后的第二周结束时进行根管治疗。在第三周结束时，即在拆除夹板之前进行根管充填。临床和影像学检查（随访期：6个月至3.5年）显示没有牙根吸收，根尖愈合良好，支持组织健康。
