Neck function in rhythmic jaw activities. Birgitta Häggman Henrikson 2004. Department of Odontology, Clinical Oral Physiology, Umeå University, and Centre for Musculoskeletal Research, Gävle University, Sweden. Previous studies in animals and humans show anatomic and physiological connections between the trigeminal and the cervical regions. This investigation tested the hypothesis of a function...

1. The kinematics of sagittal-plane jaw motion were assessed in mastication and speech. The movement paths were described in joint coordinates, in terms of the component rotations and translations. The analysis focused on the relationship between rotation and horizontal translation. Evidence was presented that these can be separately controlled. 2. In speech, jaw movements were studied during c...

this case report presents a combination of surgical and prosthetic solutions applied to a case of oral implant rehabilitation in post-oncologic reconstructed mandible. bone resection due to surgical treatment of large mandibular neoplasm can cause long-span defects. currently, mandibular fibula free flap graft is widely considered as a reliable technique for restoring this kind of defect. it re...

objective: the aim of this study was to assess skeletal relapse in patients who underwent mandibular setback by bilateral sagittal split ramus osteotomy (bssro) and osteosynthesis wiring techniques. materials and methods: in this semi-experimental study, 10 patients (8 women, 2 men) with 3-8 millimeters overjet underwent mandibular setback with bssro, osteosynthesis wiring and inter maxillary f...

Changes in the feeding mechanism with feeding behavior were investigated using high-speed video and electromyography to examine the kinematics and motor pattern of prey capture, manipulation and transport in the spiny dogfish Squalus acanthias (Squalidae: Squaliformes). In this study, Squalus acanthias used both suction and ram behaviors to capture and manipulate prey, while only suction was us...

conclusions the recurrence of hyperparathyroid hypercalcemia in htp-jt syndrome after an initial total parathyroidectomy is a well-known condition necessitating careful management, an evaluation of any underlying genetic abnormality, and a family examination. a surgical treatment and surveillance of calcium and pth measurements are necessary to prevent a recurrence. introduction cancer in the p...

Though there are no available statistics, about 5,000 cosmetic jaw operations seem to be performed yearly in South Korea [1]. The frequency of jaw surgery is increasing in South Korea and in the United States. Recently, serious complications, including mortality, have been reported in the mass media. An editorial of a Korean daily newspaper insisted that the Korean Medical Association and the a...

primitive neuroectodermal tumor (pnet) is usually an aggressive, rapidly progressing and metastasizing tumor. occurrence of this type of tumor in the kidney is considered as unusual and few cases have been reported so far. we present a metastatic pnet arising probably from the kidney in a 17-year-old female patient with local invasion and metastasis to the stomach. pnet should be considered as ...
