Using Cone-beam CT Measuring The Temporomandibular Disorders Joint Space And Analysis

Objective:The aim of the present study was to compare Cone-beam computerized tomography findings and joint space measurement in Temporomandibular disorder and non-TMD joints,and to correlate these findings with the clinical diagnosis.Methods:The study was conducted on 30 cases of patients diagnosed with Temporomandibular joint disorder and 30 cases of Temporomandibular joint healthy adult volunteers head CBCT scanning,using CBCT measurement software included with the relative position measuring condylar sagittal,axial and coronal,and Comparison of bilateral symmetry condylar position.results:The joint space(coronal) of mean 2.295(1.3025)mm;mean before clearance 1.705(1.1725)mm,after a mean interval 2.680(1.5025)mm,mean medial clearance 3.995(1.4475)mm, outer space mean 1.380(1.035)mm;where in the gap on the joint,the former space,outer space,after the gap,the inner gap differences were statistically significant(P<0.05).Conclusion:Healthy adults condylar located glenoid fossa the median, bilateral condylar position substantially symmetrical,the next bit,CBCT image measurement after temporomandibular joint disorder patients condylar located is one of the effective method to evaluate the condylar position.
