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).
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 ...
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.)
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 ...
Articulating paper is a diagnostic tool used in dentistry to highlight occlusal contacts and the distribution of occlusal forces. That is, it marks those points on the teeth where the teeth contact during biting and grinding. [1] Articulating paper is made of a thin, non-adhesive paper strip covered in fluorescent ink or dye-containing wax. [2]
The distance between those points is equal in most humans and amounts on average to about 10 cm. [2] The triangle is therefore an equilateral triangle in those cases. William Gibson Arlington Bonwill (1833–1899) was the first to describe this.
In anatomy, the Curve of Spee (also called von Spee's curve or Spee's curvature) is defined as the curvature of the mandibular occlusal plane beginning at the canine and following the buccal cusps of the posterior teeth, continuing to the terminal molar. According to another definition the curve of Spee is an anatomic curvature of the occlusal ...
When a tooth occludes in an undesirable contact point, it prevents other teeth from achieving the ideal and harmonious contact points. There are four types of occlusal interference: 1. Centric 2. Working 3. Non-working 4. Protrusive Occlusal interference can be managed by removing the premature contact point or through restorative materials. [40]
