Orthodontic treatment of an eruptive disturbance of the mandibular first permanent molar / 대한치과교정학회지

ABSTRACT

Eruptive disturbance of the permanent lower first molar is an uncommon condition caused by physical barriers on the eruption path or failure of the eruptive mechanism. Once eruptive disturbance of the permanent lower first molar is diagnosed, treatment should be started as soon as possible to establish a normal eruption pathway and to avoid any detrimental effects on the developing occlusion. A case of primary retention of the mandibular first permanent molar treated with operculectomy and forced eruption which showed good treatment results and stability is described.
