Increased occlusal stability: teeth are less likely to drift, occlusal contacts are likely to be maintained etc. Increased success of restorations : excessive wear , fractures, cracks are less commonly observed where there is an ideal occlusion
The key comparison between them is the amount and part of the tooth that they cover. An inlay will incorporate the pits and fissures of a tooth, mainly encompassing the chewing surface between the cusps. An onlay will involve one or more cusps being covered. If all cusps and the entire surface of the tooth is covered this is then known as a ...
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.
In order to accept a stainless steel crown, the entire occlusal surface should be reduced by 1–1.5 mm and interproximally contacts should be cleared by cutting a thin mesial and distal portion or slice subgingivally by holding the tip of a thin high-speed bur at 15–20° relative to the long axis of the tooth, to avoid the creation of a ...
When exploring different complete denture occlusal schemes, it is more useful to define occlusion as the relative movement of one object to another viz the dynamic relationship between mandible to the maxillae during function. Bilateral balanced occlusion and non-balanced occlusion are two separate entities that make up complete denture occlusion.
The right deciduous maxillary canine is known as "C" and the left one "H". In international notation, the right deciduous maxillary canine is known as "53" and the left one "63". In the universal system of notation, the permanent maxillary canines are referred to by numbers. The right permanent maxillary canine is known as "6" and the left "11".
Back teeth showing fissure system. Dental caries is an upset of the balance between loss and gain of minerals from a tooth surface. [3] The loss of minerals from the teeth occurs from the bacteria within the mouth, fermenting foods and producing acids, whereas the tooth gains minerals from our saliva and fluoride that is present within the mouth.

[77] [78] However, leaving the primary teeth in place may run the risk of tooth infraocclusion where the occlusal surface is below that of adjacent teeth. [33] [72] Despite this, the retention of primary teeth, particularly molars, are more susceptible to occlusal wear, over-eruption of opposing teeth and the loss of inter-occlusal space. [79]
