Patients presenting with the complaint of antisocial snoring have very few options available to them of proven efficiency. Mandibular advancement devices worn intra-orally at night, have recently been shown in controlled trials to help mild to moderate obstructive sleep apnoea. However, there are no properly controlled studies with objective measurements on the use of such appliances for the ma...

The purpose of this study involving a sample of children with single central incisor crossbite was to determine the relationship between clinical crown lengths of the crossbite and noncrossbite mandibular incisors, incisor irregularity, and orthodontic correction of the crossbite. In addition, for comparison, the normal maturational change in position of the labial gingival margin of mandibular...

statement of the problem this study was designed to investigate the complications after surgical removal of mandibular third molars. patients and methods six hundreds and ninety eight lower third molars among 450 patients surgically extracted by general dentists from april 2005 to april 2006 were selected for this study. data were recorded by completing questionnaires regarding post surgical co...

condylar dislocation is not an uncommon condition and occurs when the condyles are displaced anterior to the articular eminence and are unable to reduce back into the glenoid fossa. long-standing dislocations are difficult to treat with the conservative methods and usually need surgical intervention. in this paper, a long-standing dislocation treated by bilateral extra-oral ramus osteotomy is d...

INTRODUCTION Obstructive sleep apnea syndrome has a high prevalence among adults. Cephalometric variables can be a valuable method for evaluating patients with this syndrome. OBJECTIVE To correlate cephalometric data with the apnea-hypopnea sleep index. METHODS We performed a retrospective and cross-sectional study that analyzed the cephalometric data of patients followed in the Sleep Disor...

PURPOSE In this study, we evaluated the tonic vibration reflex (TVR) of the masseter muscles in patients with facial asymmetry. SUBJECTS AND METHODS The study was conducted with 10 volunteers without facial asymmetry and 12 orthognathic patients with facial asymmetry. Subjects were seated in a chair and held a stimulator composed of an electric motor and an acrylic bite block between the uppe...

The purpose of this study is to compare the anterior tooth size width in patients with congenitally missing maxillary lateral incisors using the Bolton Index and divine proportion. The study sample consisted of thirty pairs of orthodontic models with unilateral (twelve patients; 7 females, 5 males) and bilateral (eighteen patients; 13 females, 5 males) absence of maxillary lateral incisors. The...

PURPOSE The aim of this prospective comparative study was to assess whether age has influence on peri-implant health in patients treated with mandibular two-implant overdentures during a 10-year evaluation period. MATERIALS AND METHODS A prospective study was carried out with two groups of edentulous patients, viz a younger (n = 52; mean age 45 years, 35-50 years) and an older (n = 53; mean a...

This study examined the association between occlusion and craniofacial morphology using univariate and multivariate statistical methods. Data were obtained from study casts and lateral cephalometric radiographs of 164 children in the early permanent dentition. The following multiple features of occlusion were assessed: molar relation, overjet, overbite, and anterior crowding. Angular skeletal m...

Obstructive sleep apnea (OSA) is characterized by episodes of pharyngeal collapse during sleep. Craniofacial alterations such as retrognathia are often found in OSA patients. Maxillomandibular advancement (MMA) surgeries increase the pharyngeal space and are a treatment option for OSA. The aim of this study was to present a successful case of MMA surgery in the treatment of OSA. A patient with ...
