Abstract
Where is the mandibular therapeutic position? In the case of unstable TMJ related to a craniomandibular dysfunction must be treated by the decision of the therapeutic condylar position. If we decide to change the condylar position, we could have as objectives to change the mandible forward （sagittal plane） and to look for physiological condylar position. The quantity of the anterior reposi tioning is depending of: condylo-discal-eminence relations and stability of condylar end position. A new ICP, in a protuded mandibular position, should be stabilized by occlusal support and retrusive guidance.
