Abstract

Objective: To explore the relationship between the size of temporomandibular joint (TMJ) condyle and the sagittal disc-condyle position and the relationship between the condylar size and craniofacial structure.

Methods: Seventy-four subjects (23.82 ± 3.77 years) underwent cone beam computed tomography (CBCT) and lateral cephalograms for orthodontics and volunteered to undergo magnetic resonance imaging (MRI). Mimics was used to calculate the volume and surface area of the condyle. MRI was used to evaluate the sagittal disc-condyle position. The lateral cephalograms were analyzed by Jarabak analysis.

Results: The condylar volume and surface area were negatively correlated with the sagittal disc-condyle position. The condylar volume and surface area were positively correlated with Ar-Go, S-Go, and S-Go/N-Me*100% (p < 0.05) and negatively correlated with ∠Ar-Go-Me and ∠N-Go-Me (p < 0.05).

Conclusion: Condylar size was negatively correlated with the sagittal disc-condyle position. The condylar size was correlated with the vertical skeletal pattern.

成人颞下颌关节髁状突大小与矢状盘-髁状突位置之间的关系。

目的探讨颞下颌关节（TMJ）髁状突大小与矢状盘-髁状突位置之间的关系，以及髁状突大小与颅面结构之间的关系：74名受试者（23.82 ± 3.77岁）接受了锥形束计算机断层扫描（CBCT）和正畸侧头颅影像检查，并自愿接受磁共振成像（MRI）检查。Mimics用于计算髁突的体积和表面积。核磁共振成像用于评估椎间盘-髁状突的矢状位置。通过 Jarabak 分析法对侧头颅影像进行分析：结果：髁突体积和表面积与矢状面椎间盘-髁突位置呈负相关。髁突体积和表面积与 Ar-Go、S-Go 和 S-Go/N-Me*100% 呈正相关（p p 结论）：髁突大小与椎间盘-髁突的矢状位置呈负相关。髁突大小与垂直骨骼模式相关。

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.
