I n previous investigations, the peculiarities of the rotational patterns of the jaws during growth have been studied. ‘3 2, 4, *a It has been suggestedi that mandibular rotation may be a mechanism of adjustment of the mandible to the maxillary complex. Anterior mandibular rotation seems to be a process of shortening of the mandible related to specific changes in gonial angle and condylar growt...

OBJECTIVE To evaluate the changes in the jaws and the upper airways of unilateral temporomandibular joint ankylosis patients who underwent condylar reconstruction via autogenous coronoid process grafts using cone-beam computed tomography (CBCT). STUDY DESIGN The 27 included patients underwent CBCT examinations at three stages: T0 (within two weeks before surgery), T1 (two weeks after surgery)...

BACKGROUND Maxillomandibular advancement (MMA) surgery is a surgical treatment option for treating the patients with obstructive sleep apnea (OSA). Surgical treatment of OSA by MMA surgery is a problem when it is encountered with an edentulous patient because of the intermaxillary fixation problem of the jaws. A paucity of information is available concerning MMA surgery for edentulous patients....

The aim of this study was to develop a more sophisticated model of the spleen tissue and investigate its interactions with a three-fingered laparoscopic grasper. The spleen tissue, modeled as a hyper viscoelastic material, was subjected to external loadings, imposed by rigid grasping jaws. The tissue deformation as well as the sliding occurrence between tissue and jaws was investigated using no...

BACKGROUND AND OBJECTIVES We assessed resection time and collateral thermal tissue damage of ultrasonically activated surgery (UAS) and high-frequency blade-enhanced bipolar electrosurgery (BE) in laparoscopic bowel surgery. METHODS We compared UAS laparoscopic intracorporeal small bowel mesentery re-section with an equivalent procedure performed with BE in a porcine model. Resection was defi...

Successful implant treatment includes osseointegration as well as prosthetically optimal positions of the implants for esthetics and function. Computer-assisted oral implant surgery offers several advantages over the traditional approach. The purpose of this report was to evaluate a complex case of a 28-year-old female patient who lost all her teeth as a result of a aggressive periodontal disea...

BACKGROUND Increasing numbers of dental patients are taking bisphosphonate medications for a variety of indications. These drugs may be associated with poor healing, spontaneous intraoral ulceration and bone necrosis in the oral and maxillofacial region. CASE DESCRIPTION The authors describe a case of osteonecroSis of the jaws in a patient receiving long-term bisphosphonate therapy for cancer...

There is a lot of applications for manipulating industrial robots nowadays. Maximizing the tasks that can be assigned to robot manipulators one criteria deciding if their application appropri-ate. The article discusses topology optimization gripping jaws an reduce jaws' weight. previously used element made C50E steel was optimized weight jaws. Shape performed based on analysis from CAD programs...

OBJECTIVES The aim of this study was to verify psychometric properties of the Polish version of the Job-related Affective Well-being Scale (JAWS). Specifically, theoretical 4-factor structure (based on the dimensions of pleasure and arousal) and reliability of the original - 20-item JAWS (van Katwyk et al., 2000) and the shortened - 12-item (Schaufeli and Van Rhenen, 2006) versions were tested....
