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). (Institute of Dentistry Aberdeen University)
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 ...
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]
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.

Point on the occlusal plane located perpendicular to the distal surface of the crown of the lower first molar Condyle CI: A point on the condyle head in contact with and tangent to the ramus plane Soft Tissue DT: Point on the anterior curve of the soft tissue chin tangent to the esthetic plane or E line Center of Cranium CC
The mesial side of the maxillary central incisor shows the crown of the tooth as a triangle with the point at the incisal edge and the base at the cervix. [10] The root appears cone shaped with a blunt apex. Unlike most other teeth, a line drawn through the center of the incisal edge will also cross through the center of the root apex. [14]
