Background/purpose: Occlusion is an important component of temporomandibular joint (TMJ). Little is known about the association between missing teeth and TMJ changes. The purpose of this study was to determine if a correlation exists between unilateral missing posterior teeth and changes in the inclination of the articular eminence (AE). Materials and methods: A total of 106 joints in 53 patients (20 men and 33 women) with unilateral posterior edentulism were included. In the same patients, the sagittal outline of the AE and glenoid fossa was traced in panoramic radiographs. The sagittal condylar path inclination was constructed by joining the crest of the glenoid fossa and the crest of AE. This was then related to the constructed Frankfurt's horizontal plane to determine the inclination of AE. The results were subjected to the one-way analysis of variance test. A P value of <0.05 was considered to be statistically significant. Results: In this study 27% of the individuals were right posterior edentulous and 26% were left posterior edentulous. The mean value of AE inclination was 37.7 , ranging from 4 to 58 . A trend showing increased inclination angle in the nonmissing side compared with the missing side was observed (P > 0.05). The inclination of AE in men was higher than in women on both the missing side and the nonmissing side (P > 0.05). The symmetry equality between the missing and the nonmissing side joint was 1.89%. This value was higher (3%) in the female group Please cite this article in press as: Chiang M-T, et al., Evaluation of missing-tooth effect on articular eminence inclination of temporomandibular joint, Journal of Dental Sciences (2015), http://dx.Journal of Dental Sciences (2015) xx, 1e5than in the male group (0%). Comparing the absolute mean differences, the female group showed a lower difference (9.8 ) than the male group (12.11 ). Conclusion: A wide range of values of AE inclination was found regardless of other factors such as side of teeth loss and the sex of patients.

“…The large topographical variability between the condyle and fossa is affected by the shape of the former which suffers changes due to bone remodeling. In the absence of condyle the fossa remains shallow, maintaining the characteristics found in a newborn (3).Several authors have discussed about various types of condyle and fossa shape different times without giving proper classification of condyle and fossa (4). A few authors have examined condyle and fossa morphology in computed tomography (CT) images obtained from patients with TMD and non-patients, describing four fossa shapes (5).…”

“…The inclination of articular eminence varies among people and it dictates the path of condylar movement as well as the degree of rotation of the disc over the condyle. 1,2 Many methods are used to examine the inclination of articular eminence, such as measurements on dry skulls, [3][4][5] conventional radiography 6 and tomography, 1,7 MRI [8][9][10][11] and CT. [12][13][14] However, CT machines have limitations in dentistry because of their high cost, large footprint and high radiation exposure. Cone beam CT (CBCT) has recently been developed as an alternative to conventional CT for dental and maxillofacial diagnostic osseous tasks.…”

Objective: The purpose of the present study was to investigate the articular eminence inclination and height according to age and gender in patients with temporomandibular joint (TMJ) dysfunction and healthy controls using cone beam CT (CBCT). Methods: The measurements were performed on CBCT records of 52 TMJ dysfunction patients (11 males and 41 females) and 41 control patients (17 males and 24 females). The eminence inclination and height were measured on the CBCT images. Results: The eminence inclination and height values were higher in males than in females in both TMJ dysfunction patient and control groups; however, these differences were not statistically significant (p . 0.05). While no statistically significant differences were found in the eminence inclination and height values between the age groups (p . 0.05) in the TMJ dysfunction patient group, there were statistically significant differences in the control group. The eminence inclination was highest between the ages of 21 and 30 years and showed a decrease after the age of 30 years. Additionally, the eminence inclinations of the control patients were statistically higher than those of the TMJ dysfunction patients. Conclusion: There were no statistically significant differences in eminence inclination and height according to gender. The eminence inclination reaches its highest value between the ages of 21 and 30 years and shows a decrease after the age of 31 years in healthy patients. The eminence inclination was steeper in healthy control patients than in patients with TMJ dysfunction.
