| Abstract: | Fractures of the mandibular condyle are common and include diacapitular fractures that affect the condylar head. The medial part of the condylar head is least commonly fractured, possibly due to decreased propensity for lines of force to run in the region. Micro-computed tomography (X-ray microtomography) of five temporomandibular joint specimens was conducted to explore whether trabecular bone structure correlates positively with fracture prevalence, which could reflect adaptation in response to lower exposure to physiological loads throughout life. Models of trabecular bone, and graphic representation of bone density indicated least dense bone medially, but a statistically significant ANOVA result was not obtained. Further study is required to verify whether a relationship between bone microstructure and fracture frequency exists, and whether or not this is the product of association between the directions of physiological and traumatic forces. |
