INTRODUCTION In growing patients with skeletal discrepancies, early diagnosis, evidence-based explanations of etiology, and assessment of functional factors can be vital for the restoration of normal craniofacial growth and the stability of the treatment results. The aims of our study were to compare the 3-dimensional pharyngeal airway volumes in healthy(More)
To develop an improved sustained-release (SR) formulation of exenatide (a therapy for patients with type 2 diabetes mellitus) in a biweekly dosage form with therapeutic efficacy comparable to that achieved with twice-daily injections of the drug. A SR formulation of exenatide, DA-3091, was prepared by single-emulsion solvent evaporation using(More)
OBJECTIVE To analyze the mechanical effects of the length and the various shapes such as cylindrical shape, taper shape, and dual-thread shape on the insertion and removal torque of mini-implants. MATERIALS AND METHODS Mini-implants (diameter 1.6 mm and length 6 mm and 8 mm) consisting of cylindrical, taper, and dual-thread groups were inserted and(More)
PURPOSE The objective of this study was to evaluate the three-dimensional soft tissue changes observed over time after bimaxillary surgery for mandibular prognathism using cone-beam computed tomography (CBCT) superimposed imaging. MATERIALS AND METHODS CBCT scans were obtained for 25 patients before bimaxillary surgery (T0), at 2 months after surgery (T1)(More)
PURPOSE Because condylar positioning after sagittal split ramus osteotomy of the mandible has been known to affect postoperative skeletal stability, accurate positional assessment of the temporomandibular joint after orthognathic surgery is vital to maximize stability of the surgery. The purpose of this study was to evaluate condylar changes after(More)
PURPOSE The purpose of this study was to evaluate head posture and the pharyngeal airway volume changes using 3D imaging after bimaxillary surgery in mandibular prognathism patients by null hypothesis. MATERIALS AND METHODS Cone-beam computed tomography (CBCT) scans were obtained for 25 mandibular prognathism patients before bimaxillary surgery (T1) and 6(More)
PURPOSE It has often been hypothesized that mandibular setback surgery causes narrowing of the pharyngeal airway. We examined whether the pharyngeal airway narrowed after orthognathic surgery in patients undergoing either mandibular setback surgery or bimaxillary surgery and whether the amount of narrowing of the pharyngeal airway was any different after(More)
OBJECTIVE To test the null hypothesis that the form and size of the pharyngeal airways in preadolescents do not differ among various skeletal patterns. MATERIALS AND METHODS Sixty healthy children (mean age, 11.79 ± 1.11 years) were divided into three groups by anteroposterior jaw relationships. Using cone-beam computed tomography, the inclination and the(More)
INTRODUCTION The purpose of this study was to examine whether the pharyngeal airway volume in adults with skeletal Class III malocclusion is greater than in subjects with Class I occlusion and whether the pharyngeal airway volume correlated with facial morphology. METHODS Cone-beam computed tomography scans were obtained from 60 subjects, who were(More)
BACKGROUND This study was to evaluate the stability of the bioabsorbable plate used in the orthognathic surgery for patients with prognathic mandibles and to evaluate the relapse tendency after surgery and the factors affecting the relapse. MATERIALS AND METHODS The sample consisted of 30 subjects (14 males and 16 females) who underwent bilateral sagittal(More)
