Molar-incisor hypomineralization (MIH) is a developmental enamel hypomineralized condition characteristically involving the first permanent molars and sometimes also the incisors. The affected teeth are predisposed to tooth surface loss (TSL) which may not only compromise the esthetics and function but also endanger the pulp and longevity of the teeth. This report describes the management of a patient with MIH complicated with localized TSL and lack of occlusal clearance due to dentoalveolar compensation. The atypical TSL pattern involved all anterior teeth and required the placement of Dahl appliances on both arches.
磨牙-切牙矿化不全（MIH）是一种牙釉质发育矿化不全的病症，其特征是累及第一恒磨牙，有时也累及切牙。患牙易出现牙面丧失（TSL），这不仅会影响美观和功能，还会危及牙髓和牙齿寿命。本报告描述了一名患有MIH并伴有局部TSL且因牙槽代偿导致缺乏咬合间隙的患者的治疗情况。这种非典型的TSL模式累及所有前牙，需要在上下牙弓都放置达尔矫治器。
