Each tooth can be described as having a mesial surface and, for posterior teeth, a mesiobuccal (MB) and a mesiolingual (ML) corner or cusp. [1] An occlusal view of a complete maxillary denture. The green line, indicating the dental midline, is the defining line when it comes to mesial-distal direction. The blue arrow, which indicates a mesial ...
Inlays and Onlays are contraindicated in patients with parafunctional habits and heavy occlusal forces. [citation needed] A Parafunctional habit refers to abnormal functioning of oral structures and associated muscles, for example patients who clench or grind their teeth. Occlusal forces are greater on molars when compared to premolars.
For example if there is a heavy contact or interference in RCP this may be the cause of occlusal disturbance. It is important to be able to guide the patient into RCP, as a registration may need to be taken in this position particularly if the occlusion is being reorganised, the OVD is being changed or even just for diagnostic and treatment ...
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 ...
The mesial part is that which is towards the incisors. The suffix " -flexus / -flexid " (upper molar / lower molar) is used for the open valleys in the occlusal surfaces of the hypsodont teeth. When this valleys are enclosed, they are called fossetes/fossetids (upper molar / lower molar).
The mesial view shows a slight tipping of the crown to the lingual. Both roots have flutings but they are more prominent on the mesial root. The mesial root is broader buccolingually and its apex is more blunted. The height of contour on the buccal is in the gingival third and the occlusal two thirds of the surface is flat.
Each arch also possesses its own midline, which can be used to refer to the location of contact between the mesial surfaces of the central incisors. Thus, if an individual's mandibular teeth are shifted over to the left in a mesial-distal dimension, by 2 mm, for example, that individual's midline would be said to be deviated 2 mm to the left.
Each tooth is examined from two different aspects: occlusal aspect and then the buccal and labial surfaces with the exclusion of third molars. Tooth that is not in perfect occlusion from both occlusal aspect (in perfect alignment with contact line) and buccal aspect (in perfect alignment with plane of occlusion and in correct interdigitation ...
