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
Proximal The surfaces of teeth that normally lie adjacent to another tooth. Proximal includes both mesial and distal, such as when referring to the proximal surfaces of teeth. [1] Quadrant Dental quadrants The dentition is divided into four quarters. The two dental arches form an oval, which is divided into quadrants which are numbered from 1 ...
A cusp is an elevation on an occlusal surface of posterior teeth and canines. It contributes to a significant portion of the tooth's surface. Canines have one cusp. Maxillary premolars and the mandibular first premolars usually have two cusps. Mandibular second premolars frequently have three cusps--- one buccal and two lingual.
(Occlusal caries accounts for between 80 and 90% of caries in children (Weintraub, 2001).) Unlike brushing, fluoride leads to proven reduction in caries incidence by approximately 25%; higher concentrations of fluoride (>1,000 ppm) in toothpaste also helps prevents tooth decay, with the effect increasing with concentration up to a plateau.

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.
Attrition occurs as a result of opposing tooth surfaces contacting. The contact can affect cuspal, incisal and proximal surface areas. [2] Indications of attrition can include: [3] Loss of tooth anatomy: This results in loss of tooth characteristics including rounding or sharpening of incisal edges, loss of cusps and fracturing of teeth. Enamel ...
The Michoacán State Attorney General's Office has launched an investigation into the murders of California couple Gloria Ambriz, 50, and Rafael Cardona, 53, who were attacked while on vacation.
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.
