In this paper, we present new developments in the area of 3D human jaw modeling and animation. CT (Computed Tomography) scans have traditionally been used to evaluate patients with dental implants, assess tumors, cysts, fractures and surgical procedures. More recently this data has been utilized to generate models. Researchers have reported semi-automatic techniques to segment and model the hum...

INTRODUCTION Osteonecrosis of the jaw is a serious side effect in patients receiving nitrogen-containing bisphosphonates intravenously due to malignant diseases. Albeit far less frequently, osteonecrosis of the jaw has also been reported to occur due to the oral administration of nitrogen-containing bisphosphonates due to osteoporosis. Annual infusions of zoledronic acid have been recommended i...

We investigated the jaw opening degree and jaw opening pathway on 138 normal subjects and 104 abnormal subjects to make an objective basis of the jaw opening pathway as one of the examinations of stomatognathic dysfunction. As examining the terminal hinge opening pathways we distinguished the initial phase in which the movement of the condyle was considered mainly to be rotation from the second...

Objectives To develop a method for detecting jaw positions during jaw-tracking delivery to ensure an accurate of radiation patients using electronic portal imaging device (EPID) in the cine mode on linear accelerator radiotherapy.

Recent studies of human arm movement have suggested that the control of stiffness may be important both for maintaining stability and for achieving differences in movement accuracy. In the present study, we have examined the voluntary control of postural stiffness in 3D in the human jaw. The goal is to address the possible role of stiffness control in both stabilizing the jaw and in achieving t...

Speech production involves some of the most precise and finely timed patterns of human movement. Here, in the context of jaw movement in speech, we show that spatial precision in speech production is systematically associated with the regulation of impedance and in particular, with jaw stiffness--a measure of resistance to displacement. We estimated stiffness and also variability during movemen...
