Introduction to Dental Occlusion: Key Concepts and Anatomy

A condyle refers to a specific anatomical structure in the human body, specifically in the lower jaw, and is involved in the jaw movement and articulation.

The Glenoid Fossa is a specific anatomical feature related to the skull structure, not to be confused with other unrelated terms.

A tubercle is a small rounded projection or protuberance, and in anatomy, it specifically refers to a slight elevation on a bone that serves as an attachment point for muscles or ligaments. The incorrect answers provided are misleading in their descriptions and do not accurately define a tubercle.

The term 'Working Side' refers to the side of the mandible where movement occurs towards the cheek during mastication. This side typically experiences greater support and condyle pivots within the socket.

Centric Relation (CR) is a specific position of the mandible in relation to the maxilla where the condyles are placed in their most anterior and superior position. This position is crucial for various dental procedures and treatments, as it helps in determining proper occlusion and function of the temporomandibular joint (TMJ). It is different from centric occlusion, which is the habitual or maximum intercuspation of the teeth.

Maximal Intercuspal Position refers to the complete intercuspation of opposing teeth regardless of condylar position, and it may or may not rely on condylar placement.

Laterotrusion refers to the movement of the mandible where the condyle moves on the working side in the horizontal plane. This movement is important in tasks such as chewing and speaking.

Mediotrusion is the movement of the condyle towards the nonworking side, which is a lateral movement. It is important in the study of mandibular movements and occlusion.

Protrusion in dentistry refers to the position of the mandible being anterior to centric relation, as opposed to being posterior. It is important to differentiate between protrusion and other dental terms to properly diagnose and treat patients.

Centric Occlusion refers to the position of the teeth when the jaw is in centric relation, not when it is in a protrusive or misaligned position.

Eccentric occlusion refers to any tooth contacts other than the ideal centric occlusion position, including working, balancing, and protrusive contacts.

Vertical Overlap refers to the situation where the maximum teeth extend vertically over the main teeth. It is important in various fields, such as dentistry and engineering, to ensure proper alignment and functionality.

Class I occlusion is considered normal when the mesiobuccal cusp of the upper first molar falls in the buccal groove of the lower first molar, creating a proper alignment for functional occlusion.

Class II malocclusion is characterized by the mesiobuccal cusp of the upper first molar being anterior to the buccal groove of the lower first molar, resulting in a deficient chin.

In Class III malocclusion, the relationship between the mesiobuccal cusp of the upper first molar being posterior to the buccal groove of the lower first molar results in an excessive chin length and a characteristic underbite appearance.

VDO specifically relates to the vertical dimension of occlusion in dentistry, which is crucial in ensuring the proper alignment and functionality of the dental arches.

Occlusion refers to the way the upper and lower teeth come together in the mouth, specifically during chewing or when the jaw is at rest. It is important for proper alignment and function of the teeth.

Malocclusion refers to the misalignment of teeth and jaws, leading to a 'bad bite' which can result in various health and dental issues. It is different from a toothache, sore throat, or temporary discoloration of teeth.

TMJ commonly refers to the temporomandibular joint, which is the joint that connects your jaw to your skull. It is responsible for movements like chewing, speaking, and yawning.

TMJ stands for temporomandibular joint, which is the joint that connects your jaw to your skull. For more detailed information, it is recommended to visit the provided link to the Wikipedia page dedicated to TMJ.
