[The centric relation. III. Usefulness of 3 interocclusal registration materials during mounting of the models on an articulator].

3 waxes commonly used to record interocclusal positions are tested on an articulator. All recordings are made at the same opening and the condylar variations are analysed with a Buhnergraph. Soft materials may induce errors and relining the interocclusal records allows a higher degree of accuracy.
