摘要

骨黏連低萌發位是因牙骨質與齒槽骨融合造成的萌發異常，早期診斷與適合的治療有助於預防可能產生的齒列問題，例如空間喪失、齒槽骨發育不良、乳牙延遲脫落等。治療時需考慮的因素有病患的年紀、咬合面低下的程度、繼生齒是否存在以及其位置以及相關的齒列問題嚴重程度。本文敘述一第二乳臼齒骨黏連的病例及其治療時的考量。

An ankylosed infra-erupted tooth is a tooth failed to erupt because of root cementum fusion to the alveolar bone. Early diagnosis and proper treatments are important to prevent several problems, such as space deficiency, insufficient development of alveolar bone and delayed exfoliation of the ankylosed tooth. The age of the patient and the severity of clinical symptoms and signs are key factors for treatment planning. This case report presents the treatment consideration of ankylosed primary second molar and conservative approach to managing unerupted lower premolars.
