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.
