The method used to validate or refute the arguments of the centric relation was based on deductive syllogisms evaluated with the theory of sets and truth tables. The conclusions were: centric relation is not a state of a muscular tonic contraction; any articular pathology in relation with anterior displacement of the disc is associated to a superior and posterior position of the mandibular condyle, which excludes condilar position in maximal occlusion in relationship with articular diseases; we conclude that, if maximal occlusion is opposite to a posterior-superior position of the mandibular condyle, then it is not a position that produces an anterior displacement of the disc; the ideal statement of the mandibular condyle would be associated to the interocclusal free space because of muscular balance. Otherwise it is known that is a variable position and it is associated to functional, systemic, stressing, biotyping factors.  (Rev Esp Ortod. 2010;40(4):245-252)
