- The condyle position is important for the balance of the stomatognathic system. The changes of the condyle position from the normal position can cause Temporomandibular disorders (TMD). Malocclusions may cause condyle position changes at the Temporomandibular joint (TMJ). Treatment of skeletal class II malocclusion is expected to change the position of the condyle into a normal position. The condyle position is measured using two reference lines; Tuberculum sella to Cribiform (TC line) and vertical T line. TC line is formed by tuberculum sella (T) and Cribiform (C); the vertical T line is formed by the line that passing through point T and is perpendicular to the TC line. The angular measurement of condyle is formed by point Condylion (Co)-T-vertical T line and the position of condyle is formed by Co to TC line and Co to vertical T line. This research is cross sectional design study with analytical statistical approach which compared the position and angular condyle from tracings 36 lateral cephalometric radiograph before and after fixed appliances orthodontic treatment in skeletal Class II malocclusion with maxillary pragmatism. The different condyle position in Co-TC line, Co-vertical T line and angular Co-T-vertical T line shows a significant results (P=0.001) in skeletal Class II malocclusion with maxillary pragmatism. The distance of the Co to TC line increased, Co to vertical T line and angular Co-T-vertical T line is reduced after fixed appliances treatment in skeletal Class II malocclusion with maxillary pragmatism.
