Objective: To investigate the cranial base morphology in skeletal Class I, II, III patients and to find any correlation. Materials and methods: Pretreatment lateral cephalograms of 75 patients were taken, 25 patients each belonged to Class I, II and III skeletal malocclusion respectively, between age group of 14 and 25 years. Results: The significantly more acute angle N-S-Ar reflected increase...

INTRODUCTION Internal derangement (ID) of the temporomandibular joint (TMJ) can cause facial asymmetry. The purposes of this study were to analyze the relationship between facial asymmetry and TMJ ID by using posteroanterior cephalometric variables, and to compare the findings with the results of magnetic resonance imaging (MRI). METHODS The sample consisted of women seeking orthodontic treat...

OBJECTIVE The purpose of this study was to evaluate the horizontal changes in the condylar head with bent plate fixation after sagittal split ramus osteotomy (SSRO) with and without a Le Fort I osteotomy. STUDY DESIGN Of 47 Japanese patients with mandibular prognathism, 24 underwent SSRO and 23 underwent SSRO in combination with a Le Fort I osteotomy. A 3-5-mm gap was made between the proxima...

The aim of this study was to determine if cephalometric measurement differences occurred between two groups of similarly aged female adolescents which differed with respect to their diagnoses of temporomandibular joint disc position on magnetic resonance images (MRI). One group consisted of 17 female adolescents exhibiting complete bilateral disc displacement affecting the temporomandibular joi...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013008998 DESCRIPTION An 18-year-old patient came to the Department of Oral Medicine and Radiology, to get a replacement for the missing mandibular front tooth. The patient gave a history of trauma to the anterior region a few years ago. Intraoral examination revealed missing mandibular ...

The purpose of the present study is to examine the effects of an orthopedic force produced by chincup treatment in patients with Class III malocclusion. Anteroposterior maxillary and mandibular changes were examined as were changes in the vertical dimension. Further, the possibility of posterior displacement of temporomandibular joints in treated Class III subjects was evaluated. Serial lateral...

The objective of this systematic review was to estimate the efficacy of protraction facemask on the correction of Class III malocclusion in the short term. A systematic review of articles was performed using different electronic databases (PubMed, Ovid, Cochrane Central Register of Controlled Trials, Web of Science, LILACS, and Google Scholar). Search terms comprised 'orthopedic treatment' and ...

BACKGROUND The aim of this study was to better understand how surgical repositioning and stabilization of anteriorly displaced articular discs using the Mitek mini-anchor technique affects condylar growth in growing patients with adolescent internal condylar resorption (AICR). METHODS Twenty-two adolescent patients diagnosed with AICR and anterior temporomandibular disc displacement were comp...

BACKGROUND To emphasize the characteristics and possible pitfalls of nerve reposition in cases of severe bone resorption in the posterior mandibular area, and to modify hard- and soft-tissue manipulation accordingly. METHODS We analyzed retrospectively, 7 patients in which we performed full arch lower jaw rehabilitation. The patients presented for oral rehabilitation having a minimal residual...

The use of the Finite Element Method (FE) is an appropriate way to study occlusal forces and tooth movement. The purpose of this study was to evaluate the effects of different occlusal contact patterns on tooth displacement in an adult dentition using a three-dimensional FE model of a human maxilla and mandible. Initially, images of a computerized tomography scan were redrawn in a computer prog...
