修复接近或低于牙槽嵴的牙折牙是一个错综复杂的问题,治疗这种牙的牙髓也难于消毒。延长临床牙冠的正确方法取决于临床和X线照片上的改变。切除龈组织以暴露所需的牙组织即可获得预期的效果,但常需重建患牙和邻牙区的骨组织外形。本文目的是对需要进行牙髓与/或修复前作牙周手术的牙折进行分类并提出与此相应的牙周治疗。在牙槽嵴上需暴露多少牙组织才能使有修复体的牙周组织健康地存在,这是十分重要的。应在牙槽嵴上露出3～4mm健康牙组
Repair of teeth near or below the crest of the alveolar ridge is an intricate problem that is difficult to treat with the dental pulp of such teeth. The correct method of extending the clinical crown depends on the clinical and radiographic changes. The removal of gingival tissue to expose the desired tooth tissue to achieve the desired effect, but often need to reconstruct the bone shape of the affected tooth and the adjacent tooth. The purpose of this paper is to classify the teeth that need periodontal surgery prior to pulp and / or repair and propose periodontal treatment accordingly. It is important to know how much tooth tissue is exposed in the alveolar ridge in order for the periodontal tissue with the restoration to be healthy. Should be exposed in the alveolar ridge 3 ~ 4mm healthy teeth group
