Model surgery is the classical requirement for fabricating an intermediate splint for bimaxillary surgery. However, several sources of error complicate the conventional manual technique for making an intermediate splint, and it can be difficult to reposition the cast model of the upper jaw in the desired position. Additionally, the manual procedure is time consuming and requires a lot of labora...

PURPOSE The purpose of the article is to present 8 new cases of metastatic tumors occurring in the jawbones, their clinical features , diagnostic workup and management. PATIENTS AND METHODS The records of 8 patients with metastatic jaw lesions were reviewed. Demographic data, presenting symptoms, primary tumor site, radiographic findings, bone scintigraphy , histopathology and clinical manage...

Previous reports have indicated that biting behavior is enhanced in rats that are subject to acute stress. Several methods have been proposed for studying this phenomenon, one of which is the electromyography (EMG) of the jaw muscles. In this study, we compared total EMG activity with the EMG activity related to biting behavior, as determined by video monitoring, before and after restraint stre...

BACKGROUND Orthognathic surgery is required in 25% to 35% of patients with a cleft lip and palate, for whom functional recovery and aesthetic improvement after surgery are important. The aim of this study was to examine maxillary and mandibular changes, along with concomitant soft tissue changes, in cleft patients who underwent LeFort I osteotomy and sagittal split ramus osteotomy (two-jaw surg...

This study evaluated 1) the efficacy of packing autologous fat grafts around temporomandibular joint (TMJ) total joint prosthetic reconstructions to prevent fibrosis and heterotopic bone formation and 2) the effects on postsurgical joint mobility and jaw function. One hundred fifteen patients (5 males and 110 females) underwent TMJ reconstruction with total joint prostheses and simultaneous fat...

purpose: to evaluate the clinical findings and surgical management of patients with congenital unilateral double elevator palsy (dep) or monocular elevation deficiency (med) methods: in a non-comparative interventional case series, 27 consecutive cases of dep were studied. hypotropia, elevation deficiency, and pseudoptosis were corrected by knapp or callahan procedure with or without inferior r...

Nowadays, the remote technique of minimally invasive surgery is a popular surgical method due to its established benefits patients compared with conventional open surgery. However, surgeon’s only contact operated tissue or organ through his instrument, so he feels less. This study focuses on numerical optimization laparoscopic grasper mechanism designed at TU Delft achieve best mechanical prope...

The limitations of the current methods of quantifying the surgical movements of facial bones inspired this study. The aim of this study was the assessment of the accuracy and reproducibility of directly landmarking of 3D DICOM images (Digital Imaging and Communications in Medicine) to quantify the changes in the jaw bones following surgery. The study was carried out on plastic skull to simulate...

17 patients with severe (median percentage above ideal weight 100%) and resistant obesity underwent jaw wiring. There were no major complications and patients tolerated the procedure and subsequent minor inconveniences. All patients lost weight at a rate (median 25-3 kg in six months) comparable with that of intestinal bypass surgery and one achieved and maintained her ideal weight. Two-thirds ...
