Purpose: To understand the relationship between anterior disc displacement of the temporomandibular joint (TMJ) and the angle of the condylar and incisal path, mandibular movements during protrusive and lateral excursions were analyzed.<BR>Methods: Eighty-one joints of 53 subjects (41 females and 12 males, mean age of 32.0±12.7 y) having an anteriorly displaced disc (DD), confirmed by magnetic resonance images, were recruited for this study. Twenty-five subjects (17 females and 8 males, mean age of 37.0±13.6 y) having no disc displacement were also enrolled, as a control group (ND). Protrusive and lateral excursions of subjects were recorded with a six-degree-of-freedom jaw tracking device, to obtain the difference of the angles between the condylar and incisal paths (40).<BR>Results: Results showed that the angle of the condylar path was larger than that of the incisal path in DD, while the condylar angle was smaller than the incisal angle in ND. The condylar angle being larger than the incisal angle was possibly thought to generate reversal rotational movement under incisal teeth guided movement, to make the disc slip out into forward position.<BR>Conclusions: The relationship between the anterior and posterior guidance is thought to be a contributing factor for anterior disc displacement in TMJ.
