Impaction of mandibular second permanent molars is a rare occurrence, with prevalence rates reported to be between 0.65% and 2.0%. In the absence of systemic conditions, impactions are usually unilateral. There appears to be no consensus as to the optimal treatment for impacted mandibular second molars and treatment plans will be based upon the individual case. Treatment may involve orthodontics and/or various surgical techniques, and early diagnosis is important. This paper presents an unusual case of bilateral transverse impaction of both mandibular second and third molars that was diagnosed at 18 years of age. All impacted molars were extracted.
下颌第二恒磨牙阻生是一种罕见情况,据报道其发生率在0.65%至2.0%之间。在没有全身疾病的情况下,阻生通常是单侧的。对于下颌阻生第二磨牙的最佳治疗方法似乎尚无共识,治疗方案将根据具体病例而定。治疗可能涉及正畸和/或各种外科技术,早期诊断很重要。本文介绍了一例不寻常的病例,一名18岁患者双侧下颌第二和第三磨牙横向阻生,所有阻生磨牙均被拔除。
