Resumo: 	The purpose of this study was to analyze the condylar position in the maximum mouth opening in a group of individuals with and without temporomandibular joint disorders (TMD) using corrected magnetic resonance imaging (MRI). It was analyzed the MRIs of 200 temporomandibular joint (TMJ) of 100 adults (25 males and 75 females). The images protocol of the MRIs were in corrected sagittal plane T1, with the patient kept at a maximum mouth opening without pain. All the images were obtained parallel to the Frankfurt plane. The images were split by two lines parallel to the upper base of the image which was obtained parallel to the Frankfurt plane, tangential to the articular tubercle and the condyle of each TMJ, and set along the discrepancy of the condylar position on both sides and the position with regard to the articular tubercle. The discrepancy was 45% overall, the most common condylar position types were 5 and 6 on the right and left sides in both the male and female TMJ patients. In this regard, the highest mean values were found for the maximum mouth opening. Our results support the hypothesis that the condylar position is not directly related to the magnitude of the oral opening.
