Centric relation- untranslated hinge position of mandible to maxilla Centric occlusion - occlusion of teeth as the mandible closes in centric relation. A non-working side interference is when any tooth on the opposite side makes the first contact. Canine Guidance If however when you slide laterally a number of teeth on your working side are in contact at the same time, all sharing the load, this is called group function.
