Even while certain forms of mandibular impactions (such as inverted molars) might be considered unusual findings, mandibular impacted teeth are really one of the most regularly seen dental abnormalities. Two female patients' mandibular third molars were discovered to be inverted during a regular inspection, and two such examples are reported here in this article. Both patients underwent routine radiographic examination. Cone beam computed tomography and orthopantomogram were requested to evaluate the state of the bone and to check for any abnormalities, and inverted impacted teeth were discovered. A tooth is said to be inversed when it is placed reversed and seated upside down. Ascending ramus is the most common site for third molars in the mandible. It is also possible for a maxillary tooth to get impacted and for the tooth to be pushed all the way to the orbit's floor, though mandibular impacted teeth are more common. Only a few cases of inverted and impacted mandibular third molars have been reported in the literature. No definitive treatment protocols exist for the removal of inverted teeth. The safest protocol is conservative treatment in which the teeth are not extracted until they produce pathological signs.
尽管某些形式的下颌阻生牙（如下颌磨牙倒置）可能被视为异常发现，但下颌阻生牙实际上是最常见的牙齿异常之一。在一次常规检查中发现两名女性患者的下颌第三磨牙倒置，本文报告了两个这样的病例。两名患者均接受了常规影像学检查。要求进行锥形束计算机断层扫描和曲面断层片以评估骨状态并检查是否存在任何异常，结果发现了倒置阻生牙。当牙齿位置颠倒且牙根朝上时，就称其为倒置牙。下颌升支是下颌第三磨牙最常见的位置。尽管下颌阻生牙更为常见，但上颌牙也有可能发生阻生并被一直推到眶底。文献中仅报道了少数下颌第三磨牙倒置阻生的病例。对于拔除倒置牙，不存在明确的治疗方案。最安全的方案是保守治疗，即在牙齿出现病理症状之前不拔除。
