摘要

當前牙受到外傷，正面的撞擊力常會造成牙冠─牙根斷裂，而有復形上的困難。可能的治療術式有直接復形、矯正突出術、牙齦切除術或牙冠增長術、手術突出術或蓄意再植術等。這些術式各有其優缺點，採用何種術式需同時考慮牙齒本身的預後、美觀、剩餘齒列的咬合、患者的經濟、時間、身體狀況、合作度、個人意願等。本報告提出二牙冠─牙根斷裂病例，以蓄意再植術將牙根旋轉180度後種回原拔牙窩，術後一年牙周狀況良好，放射線根尖片顯示亦無牙根吸收的問題。(J. Family Dent. 6(2): 41-48, 2011)

When anterior teeth are traumatized, frontal impacts can often result in crown-root fractures and it is difficult to restore these teeth. Treatment options include fragment reattachment, orthodontic extrusion, gingivectomy or crown lengthening procedures, surgical extrusion or intentational replantion. These methods have both advantages and disadvantages, and the choice depends on prognosis of the tooth, esthetics, occlusion of the remaining dentition, patients' finances, time, systemic conditions, compliances and personal preferences. This report presents two cases using intentional replantation with 180-degree rotation for the treatment of crown-root fractured permanent teeth. At 1-year follow up, the periodontal conditions are stable and no root resorption can be found on the radiographic examination.(J. Family Dent. 6(2): 41-48, 2011)
