Maxillofacial characteristics affecting chin deviation between mandibular retrusion and prognathism patients

Chin cup therapy for mandibular prognathism.

Analysis of facial skeletal characteristics in patients with chin deviation.

BACKGROUND This study was undertaken to investigate the facial skeletal features associated with chin deviation. METHODS Twenty-five patients (14 males and 11 females) diagnosed with chin deviations of more than 2 mm were recruited. Fifteen skeletal landmarks, including median and lateral points, were located on posteroanterior cephalograms. The CG-ANS (crista-galli of the ethmoid-anterior na...

Candidate Gene Analyses of Mandibular Prognathism

Causation of a disease and a symptom generally is classified as genetic inheritance and environmental factors. A disease caused by a single gene disorder is defined as a disease that is attributed to a monogenic factor. A single gene disorder has been reported in more than 3,000 hereditary diseases. On the other hand, a polygenic or multifactorial disease is attributed to some susceptibility ge...

Comprehending the three-dimensional mandibular morphology of facial asymmetry patients with mandibular prognathism

BACKGROUND The purpose of this study was to elucidate the factors that cause facial asymmetry by comparing the characteristics of the mandibular morphology in patients with mandibular prognathism with or without facial asymmetry using three-dimensional computed tomography (3D-CT). METHODS We studied 28 mandibular prognathism patients whose menton deviated by ≥ 4 mm from the midline (FA group,...
