Static occlusion refers to contact between teeth when the jaw is closed and stationary, while dynamic occlusion refers to occlusal contacts made when the jaw is moving. [ 1 ] The masticatory system also involves the periodontium , the TMJ (and other skeletal components) and the neuromusculature, therefore the tooth contacts should not be looked ...
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
Intercuspal position (ICP), also known as centric occlusion, is a position in which teeth occlusion plays an important role. In the majority of population, centric occlusion is said to be averagely 1 mm anterior to centric relation in the natural dentition. [5]
Dentition is particularly useful in tracking ancient populations' movements, because there are differences in the shapes of incisors, the number of grooves on molars, presence/absence of wisdom teeth, and extra cusps on particular teeth. These differences can not only be associated with different populations across space, but also change over ...
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.)
Lingualized occlusion is defined as a form of denture occlusion that articulates the maxillary lingual cusps with the mandibular occlusal surfaces in centric, working, and non-working mandibular positions. [1] The concept of lingualized occlusion was again influenced by Gysi, when he designed a crossbite posterior teeth model concept. [8]
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 in occlusion the teeth may appear the same height which is particularly apparent for anterior teeth. Sensitivity or pain : Attrition may be entirely asymptomatic, or there may be dentin hypersensitivity secondary to loss of the enamel layer, or tenderness of the periodontal ligament caused by occlusal trauma .
