Cephalometric analysis of the middle part of the face in patients with mandibular prognathism.

BACKGROUND/AIM The middle part of the face, that is the maxilla, has always been mentioned as a possible etiologic factor of skeletal Class III. However, the importance of the relationship of maxillary retroposition towards the cranial base is still unclear, although it has been examined many times. The aim of this study was to conduct cephalometric analysis of the morphology of maxilla, includ...

Mandibular morphology in monozygotic twins: a cephalometric study.

BACKGROUND The understanding of relative effects of genetics and environmental factors on mandible growth would increase effectiveness of orthodontic therapy and treatment planning. The purpose of this study was to clarify whether the skeletal morphology of mandible is phenotypically alike in two individuals in a pair of young adult monozygotic (MZ) twins. METHODS The 90 twin pairs were class...

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...
