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.
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 ...
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]
Number of teeth: The number of denture teeth should be reduced from 8 to 6 posterior teeth. Monoplane occlusion correspondingly requires having anterior teeth with no vertical overlap thus resulting in suboptimal dental aesthetics. [20] However, some studies have suggested that a monoplane occlusion can result in reduced masticatory ability.
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). Its strength is due to the thickness of the enamel which differs among species of hominids. The hypocone appears to have evolved ...
Dental anatomy is dedicated to the study of tooth structure. The development, appearance, and classification of teeth fall within its field of study, though dental occlusion, or contact between teeth, does not. Dental anatomy is also a taxonomic science as it is concerned with the naming of teeth and their structures. This information serves a ...
