Research status on the determination of occlusal vertical dimension of edentulous jaws / 口腔疾病防治

@#It is the key step of the occlusal reconstruction to determine the correct occlusal vertical dimension for edentulous patients. Although there are several methods in clinical practice, there is no ideal way. This paper summarizes the following methods: inter-occlusal distance, closest speaking space method, pre-extraction record, face proportion division method and facial appearance observation, cephalometric analysis, electromyography, swallowing, bite force determination and self feeling method. In this paper, the current research status and the feasibility of each method are discussed.
