循序性拔牙運用於混合齒列期

Serial Extraction in Mixed Dentition

摘要


根據美國Third National Health and Nutrition Examination的調查,在不正咬合齒列中,擁擠(crowding)是一項最普遍的問題,因此,牙科治療中空間處理成為一項重要的課題。Ngan及Alkire等人依空間缺少的嚴重程度把齒列擁擠分為輕微(空間不足量少於2mm)、中等(2-4 mm)、嚴重(5-9mm)、很嚴重(大於10mm);循序性拔牙(serial extraction)是運用於嚴重擁擠程度以上的齒列中,循序性拔牙不僅可以減少齒列擁擠的機會,更可以對之後的矯正治療有所幫助,以及可以減少復位(relapse)的情況。(Taiwan J Pediatr Dent 3(1): 34-39, 2003)

並列摘要


According to the Third National Health and Nutrition Examination Survey in United States, crowding is a problem for children's dentition. Management of space problems continues to play an important role in the dentistry. Ngan and Alkire categorized the severity of space problems into mild crowding (space shortage < 2 mm), moderate crowding (space shortage 2 to 4 mm), severe crowding (space shortage 5 to 9 mm), and extremely severe crowding (space shortage> 10 mm). Serial extraction is reserved for treating severe or extremely severe crowding cases. It will facilitate the subsequent orthodontic treatment and minimize the relapse.
