 note = {Occlusal vertical dimension (OVD) refers to the vertical position of the mandible in relation to the maxilla when the upper and lower teeth are contacted at the maximum intercuspation position. The OVD is the fundamental factor to perform oral functions such as mastication and swallowing. 
This paper consists two parts which describes the definition and the decision of OVD in physiological approach in human and the mechanism of the adjustment of the OVD in the bite raised Guinea pig. 
First part, we discuss the physiological approach to dependency on centric occlusal sensation and mastication force control. 
Second parts, in order to examine how strict the OVD is adjusted in the young guinea pig, these animals were raised by fixation of a bite-raising appliance in lower incisors. The space produced between upper and lower molars was filled due to eruption of molars. After removal of the appliance, the animals reduced the raised OVD until it attained to the observed OVD level in controlled animals. Next study, it was demonstrated how the OVD was affected by the changing the muscle spindle sensation. The neurons in the trigeminal mesencephalic nucleus (MesV) were damaged for blocking input from muscle spindle in the OVD-raised guinea pigs. The result showed those animals with MesV lesions reduced very slight in the OVD. It is suggested that MesV neurons relates to the regulation ability of the OVD. Third study, in order to examine how OVD effects on jaw movement, bite-raised guinea pigs were monitored their mastication after removing appliance. The most closed position of the jaw was lower in the bite-raised animals than in controls, but other researches were similar in both groups. 
These researches suggest that the OVD is controlled in rigorous manner and the physiological approach focused on the muscle spindle to control the OVD is the most important concept in the orthodontic, prosthetic and periodontal treatment.},
