Dimensional analysis of condylar head using 3D scanned models of human dry skulls: A comparative study of measurement methods.
Objective: This study aimed to examine the dimensional characteristics of the condylar head in 3D models of dry human mandibles using two different measurement methods.
Methods: A total of 46 condylar heads from 29 dry human mandibles were scanned using a 3D scanner. Two perpendicular reference planes were used to identify the most medial, lateral, anterior, and posterior points. Measurements in the mediolateral and anteroposterior dimensions were taken using the direct measurement method, and the proposed method using the two reference planes. Paired t-tests were performed to compare the results.
Results: Significant differences were observed, particularly in anteroposterior dimensions, which were smaller when using the proposed method (p < .001).
Conclusion: Measurements of the condylar head should be taken from the outermost points. Given the nature of bone remodeling, relying solely on a single cut from CBCT images for dimensional evaluation may result in missing potentially significant changes.
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.
