Denar Combi II Articulator SystemFigure 4. The ideal functional relationship isimmediate separation of all posterior teeththe moment the mandible moves forwardfrom centric relation. Extensive studies haveshown that this results in shutting off mostof the elevator muscle contraction to reduceloading forces on the TMJs and the anteriorteeth. Setting the condylar path flatter on thearticulator will result in faster separation of theposterior teeth if the condyles travel a steeperpath forward in the patient. This has no adverseeffect on function, comfort, esthetics, orstability.When recording, the protrusive condylar path is important.There is never a problem with condylar guidance if the anteriorguidance can disclude the posterior teeth in all excursions. But ifposterior disclusion cannot be achieved, it may be necessary to relymore on the condylar path to help separate the posterior teeth. Insuch cases it is important to determine the protrusive path. This isthe only adjustment required for condylar path on the Combi II. Itcan be easily achieved with a simple straight protrusive bit recordto set the protrusive angle.6
