Abstract

ABSTRACT Purpose This survey aimed to estimate the incidence and severity of impacted teeth indicated for fenestration or fenestration and traction in patients who visited several dental institutions nationwide in Japan from 1 April 2015 to 31 March 2016. Materials and Methods An online survey was conducted, and 236 dental institutions responded, with 176 reporting their experience with cases of impacted teeth indicated for fenestration/traction. Results Of the 1,683 cases of impacted teeth indicated for fenestration/traction, 434 (25.8%), 391 (23.2%), and 858 (51.0%) were treated using fenestration alone, fenestration/traction, and fenestration/traction and orthodontic treatment, respectively. Impacted teeth were most prevalent in the anterior maxillary region, especially in the canine region, with 435 (24.0%) and 411 (22.7%) impacted teeth on the right and left quadrants, respectively. The most commonly used diagnostic criteria were the radiographic findings of clear inversion or horizontal impaction showing that spontaneous eruption would be difficult in 123 (37.4%) cases. The most severe cases indicated for fenestration/traction were those with two or more impacted teeth, observed in 279 (56.7%) cases, followed by 174 cases of root resorption of adjacent teeth (35.4%). Root resorption due to impacted teeth was most prevalent in the maxillary left lateral incisors, evident in 65 cases (24.5%). Conclusion This study found that impacted teeth often have serious sequelae such as root resorption of adjacent teeth. Thus, early detection and intervention of impacted teeth, as well as preoperative and postoperative orthodontics to establish a physiologically normal occlusion, are necessary.

日本需要开窗、牵引和正畸治疗的阻生牙的发病率

摘要目的本调查旨在评估2015年4月1日至2016年3月31日期间在日本全国多家牙科机构就诊的患者中，因开窗或开窗和牵引而导致的阻生牙的发生率和严重程度。材料和方法进行了一项在线调查，236家牙科机构做出了回应，其中176家报告了他们对需要开窗/牵引的阻生牙齿病例的经验。结果在1683例需要开窗/牵引的阻生牙中，434例（25.8%）、391例（23.2%）和858例（51.0%）分别采用单独开窗、开窗/牵引和开窗/牵引及正畸治疗。阻生牙在上颌前区最为常见，尤其是在犬齿区，右象限和左象限分别有435颗（24.0%）和411颗（22.7%）阻生牙。最常用的诊断标准是明确倒置或水平撞击的放射学检查结果，显示123例（37.4%）的病例难以自发喷发。开窗/牵引最严重的病例是有两颗或两颗以上阻生牙齿的病例，共有279例（56.7%），其次是相邻牙齿的174例（35.4%）。阻生牙齿引起的牙根吸收在上颌左侧切牙中最为普遍，65例（24.5%）可见。结论本研究发现，阻生牙常有邻牙牙根吸收等严重后遗症。因此，早期发现和干预阻生牙，以及术前和术后正畸以建立生理上正常的咬合是必要的。
