Failure of posterior teeth to erupt fully into occlusal contact produces a lateral open-bite. These problems usually are attributed to a mechanical interference with the eruptive process, either ankylosis or some soft-tissue interference. In some patients, lateral open-bite is due to a disturbance of the eruption mechanism itself so that nonankylosed teeth cease to erupt. Influences on the eruption of teeth are reviewed, and possible causes of "primary failure of eruption" are discussed. The limitations of treatment for patients with eruption failure are described and illustrated by case reports.
后牙未能完全萌出至咬合接触会导致侧方开颌。这些问题通常归因于对萌出过程的机械性干扰，即牙齿粘连或某些软组织干扰。在一些患者中，侧方开颌是由于萌出机制本身紊乱，导致未粘连的牙齿停止萌出。本文回顾了对牙齿萌出的影响因素，并讨论了“萌出原发性失败”的可能原因。通过病例报告描述并举例说明了萌出失败患者的治疗局限性。
