Abstract
Objective: To three-dimensionally evaluate the position and morphology of the TMJ in skeletal Class I with variable degrees of overbite and overjet in comparison with normal peers.
Methods: Pretreatment CBCT scans of 126 adults were retrieved. Based on the severity of overjet and overbite, the sample was divided into three main groups and six subgroups (18 patients each): the first group with a normal overbite and variable overjet degree and the second group with normal overjet and variable overbite degree. These six subgroups were compared with a third control group of normal overjet and overbite.
Results: There were significant differences in vertical condylar position, vertical and anteroposterior condylar inclinations, condylar height, and significant posterior condylar positioning in severe deep overbite, compared with the control group.
Conclusion: There were significant changes in the TMJ components in severe deep overbite cases. Therefore, sever deep overbite could be considered a predisposing factor for temporomandibular disorders.
期刊介绍:
CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians.
CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest.
CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
