Number of teeth: The number of denture teeth should be reduced from 8 to 6 posterior teeth. Monoplane occlusion correspondingly requires having anterior teeth with no vertical overlap thus resulting in suboptimal dental aesthetics. [20] However, some studies have suggested that a monoplane occlusion can result in reduced masticatory ability.
Diagram of tooth anatomy. Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)
The distinction is one of anterior (front of the body) versus posterior (rear of the body). The distinction holds in both the upper jaw ( maxilla ) and lower jaw ( mandible ). As a rough guide, it can be said that the anterior teeth are tailored to biting (breaking the food into chewable chunks) [ 1 ] whereas the posterior teeth are tailored to ...
Adult teeth are numbered 1 to 8, with deciduous (baby) teeth indicated by a letter A to E. Hence the left and right maxillary central incisor would have the same number, "1", but the right one would have the symbol "⏌" underneath it, while the left one would have "⎿".
The direction toward the back of an individual's head, as opposed to anterior, which refers to the directions toward an individual's lips. The term posterior teeth refers to premolars and molars, as opposed to incisors and canines, which are anterior teeth. [1] [5] Proximal The surfaces of teeth that normally lie adjacent to another tooth.
The Journal of Prosthetic Dentistry (2017) defines mutually protected occlusion as ‘an occlusal scheme in which the posterior teeth prevent excessive contact of the anterior teeth in maximal intercuspal position, and the anterior teeth disengage the posterior teeth in all mandibular excursive movements’ [12]
Representation of Wilson curve. The curve of Wilson is the across arch, and across median plane, curvature or posterior occlusal plane. Arc of the curve, which is concave for mandibular teeth and convex for maxillary teeth are defined by a line drawn from left mandibular first molar to right mandibular first molar.
2.c Anterior or posterior crossbite with ≤1mm discrepancy between retruded contact position and intercuspal position 2.d Displacement of teeth >1mm but ≤2mm 2.e Anterior or posterior open bite >1mm but ≤2mm 2.f Increased overbite ≥3.5mm (without gingival contact) 2.g Pre-normal or post-normal occlusions with no other anomalies.
