CONCEPT OF OCCLUSION

TOPIC: CONCEPT OF OCCLUSION

🎯 KEY FACTS

🔹Farrar appliance is a type of occlusal device which is used to position the mandible anteriorly to treat temporomandibular joint (TMJ) disk disorders.

🔹Condylar guidance of the patient is determined by a protrusive record.

🔹 ‘S’ shaped path of the glenoid fossa determines the path of movement of the condyle and determines the condylar guidance.

🔹In the natural dentition, the centric occlusion is usually 0.5–1 mm anterior to the centric relation.

🔹Concept of lingualized occlusion was proposed by Gysi in 1927, in which the maxillary lingual cusp was used as the dominant element which occluded against the corresponding position of the mandibular teeth.

🔹Reverse articulation is the occlusal relationship in which the maxillary buccal cusps are placed in the central fossae of the mandibular teeth.
