An occlusal interference is any tooth contact that prevents, or hinders harmonious mandibular movement (an undesirable tooth contact). [ 12 ] Non-working side interference (photograph) detectable with articulating paper or plastic shimstock, as the mandible moves to the left (working side).
Diagram of tooth anatomy. Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)
In this bilateral balanced occlusal scheme, the posterior teeth are set up at different angles in the coronal plane; 5° for the first premolar teeth, 10° for second premolar teeth, and 15° angle for both the first and second molar teeth. In addition, the occlusal surfaces of mandibular posterior teeth are reduced in a buccal lingual ...
Models of human teeth in maximum intercuspation. The models are transparent to allow the viewer to perceive the roots of the teeth as they reside naturally within the alveolar bone . In dentistry, maximum intercuspation refers to the occlusal position of the mandible in which the cusps of the teeth of both arches fully interpose themselves with ...
The dental midline is the midsagittal line of maxillary and mandibular dental arches possessing teeth of ideal size, shape, and position, when situated in maximum intercuspation. Each arch also possesses its own midline, which can be used to refer to the location of contact between the mesial surfaces of the central incisors .
The hypocone is found on the distal lingual side of the tooth. It fits into the grooves of the lower dentition and is an adaptation for the overall grinding and tearing of foods using the occlusal (chewing side) of the tooth surface during occlusion or mastication (chewing).
The shape of the developmental and supplementary grooves, on the occlusal surface, is described as being M-shaped. The mandibular first molars are the most common carious teeth and the most common teeth to undergo endodontic treatment or extraction. Up to 45% of all extracted teeth are mandibular first molars.

When the lower jaw is pushed anteriorly as far as possible with some teeth in contact, it is said to be maximum protrusion. In Posselt's border movement diagram, maximum protrusion is the most anterior based on the sagittal view. Condyles are in the most anterior position and determined partly by stylomandibular ligaments. [8]
