Intercuspal position(ICP) Two aspects to describe ICP: 1.TMJ:condyles in the center of the fossae,;anterior slope of the condyle,disk,posterior slope of the eminantia keep in close contact. 2.Occlusion:normal vertical height;complete intercuspation; correct guidance. 1907

Intercuspal position(ICP) Depends on intercuspal occlusion Changes in ICO will alter ICP. 4902

Retruded contact position(RCP) Retruded contact position: that guided occlusal relationship occurring at the most retruded position of the condyles in the joint cavities. Only part of the posterior cusps are in contact, no contact in anterior teeth. It is the most posterior position of mandibule. 190
