DENT1092 & DENT1014: Course Content Review

Group function is a feature where the posterior teeth out of occlusal contact when protrusive or lateral movements are performed; Canine guided occlusion is when there are multiple contact relations between the maxillary and mandibular teeth in later excursions.
