本专题前二篇叙述了粘膜下保留活牙根是否有助于保存牙槽嵴的形态。作者在10名患者中,将试验牙齿沿牙槽嵴水平向切去临床牙冠,然后由粘膜瓣复盖并作全口义齿修复。本文报告断根的活性和位置,表面复盖软组织的完整性,以及断根根周骨组织的特征。有无牙髓感染,对于活牙根埋于粘膜下是否成功是重要的问题。因牙髓感染可导致手术的失败。判断牙髓组织情况最好采用临床方法,任何异常的牙髓反应或牙髓试验无反应的牙齿,都不能作为活牙根保留牙。选

The first two articles of this topic describe whether submucosal preservation of the living root helps preserve the shape of the alveolar ridge. In 10 patients, the trial cut the clinical tooth crown horizontally along the alveolar ridge and then covered with a mucosal flap for complete denture repair. This article reports the activity and location of root ablation, the integrity of the soft tissue covered by the surface, and the characteristics of the root bones in the root. Whether there is pulp infection, the survival of the active submucosal buried in the mucosa is an important issue. Infections due to dental pulp can lead to surgical failure. Determine the dental pulp tissue is best to use clinical methods, any abnormal dental pulp reaction or dental pulp test non-response teeth, can not be retained as a living tooth root. selected
