BACKGROUND Orthopedic functional devices, are used to improve mandibular length in skeletal class II patients. However, the orthopedic functional device with the best effect to increasing the mandibular length, has not been identified before. Thus, the aim of the present investigation was to evaluate Randomized Controlled Trials (RCT), to determine the best functional appliance improving mandib...

INTRODUCTION Dentofacial deformity, a deviation from normal facial proportions and dental relationships, is corrected by jaw repositioning in all three spatial planes, which changes the position and tension of the surrounding tissues, bones and muscles. These changes may also affect the dimensions of the pharyngeal airways (PA). OBJECTIVE The aim of this study was to evaluate and compare thre...

STUDY OBJECTIVES To evaluate the long-term effects on apneas and sleep and the tolerability of a mandibular advancement device in patients with obstructive sleep apnea. DESIGN Prospective study. SETTING Department of Respiratory Medicine, University Hospital, Umeå, Sweden. PATIENTS Thirty-three consecutively treated patients. INTERVENTIONS Individually adjusted mandibular advancement de...

This article is dedicated to the senior author Dr. Henry K. Kawamoto, Jr, who pioneered the use of orthognathic surgery to treat severe obstructive sleep apnea in 1981. Since that time, his techniques for maxillomandibular advancement have been revised and expanded for improved surgical success. Obstructive sleep apnea is a growing public health concern because it can cause hypertension, cardia...

The aim of this prospective clinical study was to evaluate the short-term and long-term skeletal and dental changes after mandibular osteodistraction with tooth-borne appliances in adult orthodontic patients. The sample consisted of 10 non-growing Caucasian patients with a Class II skeletal relationship due to mandibular deficiency, together with Class II dental malocclusion. All patients under...

This prospective clinical study examined the alterations in airway and hyoid position in response to mandibular advancement in subjects with mild and moderate obstructive sleep apnoea (OSA). Pairs of supine lateral skull radiographs were obtained for 13 female and 45 male, dentate Caucasians. In the first film, the teeth were in maximal intercuspation, while in the second the mandible was postu...

BACKGROUNDS The main problem with intraoral distraction of the mandible is the inability to achieve the three-dimensional mandibular correction as planned preoperatively. We developed a technique that allows spontaneous changes in the direction of mandibular elongation using an intraoral distractor. METHODS After mandibular osteotomy, the distractor is fixed to the distal segment of the mandi...

Background: Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder. BPPV may be due to surgery, but it is a rare complication of non-craniofacial surgery. Diagnosis and treatment of BPPV remain challenging in postoperative patients. We present a case of BPPV secondary to spinal surgery and the diagnostic and treatment outcomes. The possible underlying etiologic and pathophy...

Oral mandibular advancement devices are becoming an increasingly important treatment alternative for obstructive sleep apnea (OSA). The first aim of the study was to determine whether a new oral elastic mandibular advancement device (EMA) prevents pharyngeal airway closure during sleep in patients with OSA. The second aim of the study was to determine if the polysomnographic response to the ora...
