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 ...
Multiple contacts between the maxillary and mandibular teeth in lateral movements on the WS whereby simultaneous contact of several teeth acts as a group to distribute occlusal forces. It is preferable for this guidance to be as anterior as possible e.g. premolars rather than molars , as there is increased force applied when the contacts are ...
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.
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".

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.
The heaviest dog was an English Mastiff named Zorba, which weighed 314 pounds (142 kg). [2] The tallest known adult dog is a Great Dane that stands 106.7 cm (42.0 in) at the shoulder.

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.
