Objective: The aim of this study was to evaluate the effects of orthognathic surgery for mandibular setback – with and without combined maxillary surgery – on the upper airways (UA). Methods: Immediate lateral preoperative and postoperative cephalometric radiographs of 17 Class III patients were evaluated. Measurements of airway space (AS) diameter were taken in the sagittal plane in the hypoph...

J Korean Assoc Oral Maxillofac Surg 2012;38:354-9) Objectives: The purpose of this study was to investigate whether the age factor would be related with stability of mandibular setback surgery for patients with mandibular prognathism. Materials and Methods: We compared the relapse patterns of 47 patients divided into three age groups (termed younger, adult, and older). The younger group consist...

PURPOSE The goal of this retrospective study was to examine whether utilization of condylar positioning devices in bilateral sagittal split osteotomy leads to long-term benefits for temporomandibular joint function as compared with the manual positioning technique. PATIENTS AND METHODS The joint function of 49 patients (98 joints) who underwent bilateral sagittal split osteotomy or bimaxillar...

Background and Objective: Identifying the details of the injurious effects of alcohol seems to be decisive in nowadays with growing abuse of the substance. This study mainly aimed to assess the adverse effects of ethanol on the recalling of information in the Wistar rats. Materials and Methods: Male Wistar rats (Pasteur Institute of Iran) were evaluated using the novelty seeking behavior based ...

BACKGROUND This study constructed a partial-least-square path-modeling (PLS-PM) model and found the pathway by which the postsurgical vertical dimension (VD) affects the extent of the final mandibular setback on the B point at the posttreatment stage for the skeletal class III surgery-first approach (SFA). METHODS This study re-analyzed the data from the retrospective study by Lee et al. on 4...

The movement of vortices in superconductors due to an applied current can induce a loss of perfect conductivity. Experimental observations show that material impurities can effectively prevent vortices from moving. In this paper, we provide numerical studies to investigate vortex pinning and critical currents through the use of an optimal control approach applied to a variant of the time-depend...

The current research extended the implicit theory approach to a weight management context and merged it with value expectancy theory. Three studies investigated the hypothesis that individuals are especially unlikely to self-regulate effectively after dieting setbacks when they believe body weight to be fixed (entity theory) rather than malleable (incremental theory). Study 1 examined avoidant ...

Objectives. To investigate the correlation between frontal gaps and skeletal stability after intraoral vertical ramus osteotomy (IVRO) for correction of mandibular prognathism. Materials and Methods. Thirty-three patients with frontal gaps after IVRO-based mandibular prognathism correction were included. Three lateral and frontal cephalometric radiographs were obtained: preoperatively (T1), imm...
