低位乳磨牙伴下颌第一前磨牙水平阻生1例

摘要

低位乳牙是一种牙齿异位萌出，又称乳牙下沉或乳牙粘连，指乳牙高度不能达到咬合平面，多见于乳磨牙。本文报道1例左下颌第一乳磨牙粘连同时伴左下颌第一前磨牙水平阻生病例的诊治过程，并结合相关文献进行讨论。%A submerged deciduous tooth, also called an ankylosed tooth, is an ectopic eruption wherein the tooth cannot erupt from the occlusion plane. Normally, the deciduous molar is involved. This article reports a clinical case of a submerged mandibular deciduous first molar combined with horizontally impacted mandibular first premolar. We focus on the clinical diagnosis and treatment of this case and provide a discussion by reviewing similar literature.
