SONOGRAPHIC NORM RANGES OF CONDYLAR TRANSLATION, TMJ-SPACE WIDTH AND A COMPARISON TO SYMPTOMATIC JOINTS

Purpose: Norm ranges of condylar translation and width of the visualized lateral joint space in TMJ-sonography were assessed for prospective individual comparison of TMJ range of motion to a standard population. Methods and Materials: Fifty not othodontically pretreated, asymptomatic volunteers, differentiated by Angle class (i.e. a classification of different types of malocclusion, based on the mesiodistal relationship of the permanent molars upon their eruption and locking, and comprised of three classes: class I: normal relationship n=20, class II: distal (dorsal position) relationship of the mandible II=15,…
