摘要

融合齒( Fusion)可發生於正常的兩顆牙齒的融合,或一顆正常牙齒及一顆多生齒的融合。外觀上,融合齒與併生齒(Gemination)有時難以至分別,必須再藉自X -片之判讀來區分。但無論如何這類異常在齒列上很不美觀,同時常會影響咬合的的正常發展。本病倒報告為一顆上顎側切齒融合, 經由外科手術整形及矯正治療之成功的個案。

Fusion may occur between two normal teeth or be-tween normal tooth and a supernumerary tooth. In clinic,the differertiation of fusion from germination is not always ossible, but may be evident from radiographic examina-tion.As a rule, both fused and germinated teeth are ex-tremely unesthetic in appearance and may interfere with normal occlusal development. The presentation is a case of fused permanent lateral incisors where orthodontic therapy was performed. Therapy involved management of removing seg-ment of fused complex. The patient was pleased with his esthetic mprovement. This type of solution is more desirable than extraction and prosthetic replacement.
