中文摘要 | 下顎前牙區四顆恆門齒寬度和大於四顆乳門尺寬度和,而此寬度差即為門齒幅差(incisor liability),因此早期混合齒列換牙過程,下顎前牙排列擁擠是可預期的現象,有機會透過正常生長機制改正過渡性擁擠(transitional crowding)。超過正常程度下顎擁擠,可能引起前牙排列不對稱或牙弓完整性破壞的問題。本文透過相關文獻回顧,探討早期混合齒列下顎前牙擁擠之臨床嚴重程度診斷及對應處理方式的選擇,以提供臨床治療參考。 |
英文摘要 | Incisor liability is the result of total mesial-distal width of the four mandibular permanent incisors greater than that of the primary incisors. Thus, lower anterior crowding in the early mixed dentition is a predictable situation. However, there is possibility of certain amount of crowding be self-corrected through normal growth mechanism, leading to only transitional crowding status. Otherwise, crowding greater than normal range may cause problems such as asymmetry of alignment and disruption in arch integrity. The purpose of this article is to review diagnosis and treatment plans of lower anterior crowding in the early mixed dentition to facilitate pediatric dentists in making right diagnosis prior to proper treatment planning. |
