The current study investigated the association between temporomandibular disorders, malocclusion patterns, benign joint hypermobility syndrome and the initial condylar position. One hundred sixty-two subjects were analyzed using the Rocabado Temporomandibular Pain Analysis; Helkimo Index parameters; the Carter-Wilkinson modified test; and a mounting cast with condylar position indicator registration (MPI). The study revealed a significant association between: 1. Delta H, skeletal pattern (p=0.034); 2. Delta Y, transversal malocclusion (p=0.04); 3. right and left, Delta Z, right and left posteroinferior synovial pain (p<0.05); 4. hypermobility scale, gender (p<0.001), malocclusion pattern (p=0.021); 5. TMJ function impairment, gender (p=0.043); 6. sagittal malocclusion pattern, right temporomandibular pain analysis joint (TPAJ) (p=0.0034); 7. TMJ function impairment, left and right TPAJ (p=0.007); and 8. mandibular motion, left and right TPAJ (p=0.035, p=0.015 ). The conclusion was that anterior crossbite and condylar displacements in the vertical plane are risk factors in developing TMJ symptoms.
