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 ...
Canine guidance during right lateral excursions (Institute of Dentistry University of Aberdeen) Canine Guidance. Dynamic occlusion that occurs on the canines (on the working side) during lateral excursions of the mandible. These teeth are best suited to accept horizontal forces in eccentric movements due to their long roots and good crown/root ...
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.
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.
In anatomy, the Curve of Spee (also called von Spee's curve or Spee's curvature) is defined as the curvature of the mandibular occlusal plane beginning at the canine and following the buccal cusps of the posterior teeth, continuing to the terminal molar. According to another definition the curve of Spee is an anatomic curvature of the occlusal ...
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.
Tooth contact may also cause occlusal stress in the following circumstances: parafunction/bruxism, [27] occlusal interferences, dental treatment and periodontal disease. Although occlusal trauma and excessive occlusal forces does not initiate periodontitis or cause loss of connective tissue attachment alone, there are certain cases where ...
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".
