多数牙缺失重建探讨

A Probe into Rehabilitating Occlusion of Majority Teeth Missing

多数牙缺失的患者一般都存在的垂直距离降低，余牙面磨损，无对颌牙的余牙伸长，丧失正常的牙尖交错位等问题。目前发达国家多采用固定修复的方法（含种植义齿）进行咬合重建。本文应用学理论，结合我国目前的条件，采用整铸基托及功能印模技术对多数牙缺失后进行咬合重建，目的是总结临床实践经验，探讨多数牙缺失重建的有关问题。

It is generally to be found that decrease of occlusal vertical dimension, worn occlusive surface of remaining teeth without opposite teeth and loss of intercusping position (ICP), etc. in the patients with majority teeth missing. In western countries, fixed restorations (including implant dentures) are routinely used for the patients with majority teeth missing in order to rehabilitate occlusion. The authors applied occlusal theory, combining with the clinical facilities and used one piece casting base and functional impression technique for rehabilitation of occlusion. The purpose of this article was to summarize clinical experiences, to expore the relative problems concerning rehabilitation for patients with majority teeth missing.
