Multiple contacts between the maxillary and mandibular teeth in lateral movements on the WS whereby simultaneous contact of several teeth acts as a group to distribute occlusal forces. It is preferable for this guidance to be as anterior as possible e.g. premolars rather than molars , as there is increased force applied when the contacts are ...
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.)
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]
In this, the mesiodistal ridge of the lower posterior teeth contacted the upper posterior teeth with flat occlusal surface in order to achieve balanced occlusion. He relied on the intraoral corrections to obtain balanced occlusion. Again, his main goal was to eliminate deflective occlusal contacts and therefore increase stability of the prostheses.
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 dental arches are the two arches (crescent arrangements) of teeth, one on each jaw, that together constitute the dentition.In humans and many other species, the superior (maxillary or upper) dental arch is a little larger than the inferior (mandibular or lower) arch, so that in the normal condition the teeth in the maxilla (upper jaw) slightly overlap those of the mandible (lower jaw) both ...
Diagram showing embrasure (red triangle) between maxillary right second bicuspid and maxillary right first molar. Right lateral view. In dentistry, embrasures are V-shaped valleys between adjacent teeth. They provide a spill way for food to escape during chewing [1] which essentially aids in the self-cleansing process.
