摘要
现有的颌位关系记录托盘为上下一体式设计,在临床使用过程中无法准确获取上颌(牙合)平面、上唇下约1 mm的位置、上唇支撑度等重要信息.从而使得数字化颌托(或诊断义齿)准确性欠佳,为后继进行准确边缘整塑印模及最终颌位关系记录与转移带来困难.该文介绍了一种分体式颌位关系记录托盘的设计、临床使用方法及要点.其能够准确获取上颌(牙合)平面、上唇下约1 mm的位置、上唇支撑度等重要信息,为后继进行准确的颌位关系记录与转移提供参考,也为利用口内扫描获取数字化印模后,基于采用分体式颌位关系记录托盘获取的(牙合)平面、上唇下约1 mm的位置、上唇支撑度等信息直接制作全口义齿奠定基础.
Abstract
The present jaw relationship record tray is designed in an upper and lower integrated type,which can not accurately ob-tain important information of maxillary occlusal plane,the position about 1 mm below the upper lip and the support degree of the upper lip during clinical work.Therefore,the base-plate and occlusal-rim composite solid(diagnostic denture)is not accurate and the accu-rate jaw relationship can not be tranfered in the following steps.This paper introduces the design,clinical application process and key points of a split-type jaw relationship record tray.It can accurately obtain important information such as the occlusal plane,the position about 1mm below the upper lip,and the degree of support of the upper lip.It provides reference for the accurate recording and transfer of the jaw relationship.It also lays a foundation for the direct fabrication of full denture based on the information obtained by the split-type jaw relationship record tray after the digital impression obtained by intraoral scanning.
