Correct answer: D — The influence of the contacting surfaces of the anterior teeth on mandibular movements
Anterior guidance (incisal guidance) refers to the influence of the contacting surfaces of the anterior teeth (maxillary and mandibular incisors and canines) on mandibular movements in the protrusive and lateral excursive directions. The angle and steepness of the lingual surfaces of the maxillary anterior teeth determine how quickly the posterior teeth disocclude during excursive movements. In prosthodontics, the anterior guidance must be harmonised with the condylar guidance (determined by the TMJ anatomy) for proper occlusal function.
