目的 探讨上颌埋伏前牙正畸治疗的时机.方法 对17例20颗萌出道异常或牙根弯曲的上颌埋伏前牙摄片定位、拓展间隙后,在牙根未发育完成前进行闭合式牵引,治疗后测量埋伏牙和对侧同名牙牙根的相对长度,并采用PES(the pink esthetic score)指数对牵引后的埋伏牙进行牙龈软组织美学评价.结果 20颗埋伏前牙均牵引成功,牵引后中切牙、侧切牙和尖牙的牙根平均长度分别为(18.00±2.79) mm、(15.75±1.06) mm和(21.88±2.32) mm,略短于对侧同名牙[中切牙(20.25±1.56) mm、侧切牙(18.00±1.41) mm、尖牙(23.5±2.58) mm],牙龈软组织美学评分平均为10.65±2.68.结论 对某些萌出方向异常或牙根弯曲的埋伏牙在牙根未发育完成前进行闭合式开窗和正畸牵引可获得较好的治疗效果.
目的 探討上頜埋伏前牙正畸治療的時機.方法 對17例20顆萌齣道異常或牙根彎麯的上頜埋伏前牙攝片定位、拓展間隙後,在牙根未髮育完成前進行閉閤式牽引,治療後測量埋伏牙和對側同名牙牙根的相對長度,併採用PES(the pink esthetic score)指數對牽引後的埋伏牙進行牙齦軟組織美學評價.結果 20顆埋伏前牙均牽引成功,牽引後中切牙、側切牙和尖牙的牙根平均長度分彆為(18.00±2.79) mm、(15.75±1.06) mm和(21.88±2.32) mm,略短于對側同名牙[中切牙(20.25±1.56) mm、側切牙(18.00±1.41) mm、尖牙(23.5±2.58) mm],牙齦軟組織美學評分平均為10.65±2.68.結論 對某些萌齣方嚮異常或牙根彎麯的埋伏牙在牙根未髮育完成前進行閉閤式開窗和正畸牽引可穫得較好的治療效果.

Objective To explore the treatment timing for embeddedupper anterior teeth.Methods 20 impacted upper anterior tcethwith ectopic eruption pathway or dilacerated root from 17 orthodontic patients were selected and X-ray films were taken to determine their position.After creating space by expansion,the teeth were treated with closed eruption techniques before their root development finish.The relative lengths of root were measured after treatment for the impacted teeth and their contralateral teeth.PES index was used to evaluate the gingival soft tissue esthetics.Results Treatments for all the 20 teethwere successful.The mean root lengths for central incisor,lateral incisor and canine were (18.00±2.79) mm、(15.75±1.06) mm and (21.88±2.32) mm respectively,which were slightly shorter than that ofthe contralateral teeth [(20.25 ± 1.66) mm,(18.00±1.41) mm and (23.5±2.58) mm].The mean PES score was 10.65±2.68.Conclusions Closed eruption technique is suitable to treat embedded teeth with ectopic eruption pathway or dilacerated root before root development finish.
