Both maxillary first molars have the same letter; "D". However, the right molar has the symbol "┘" underneath it. The left molar has "└" underneath it. In the international system of notation two numbers are used to identify the tooth. The right deciduous maxillary first molar is known as "54", and the left one is known as "64".
The mandibular first molar is the tooth located distally from both the mandibular second premolars of the mouth but mesially from both mandibular second molars. It is located on the mandibular arch of the mouth, and generally opposes the maxillary first molars and the maxillary 2nd premolar. This arrangement is known as Class I occlusion.
The maxillary teeth are the maxillary central incisors (teeth 8 and 9 in the diagram), maxillary lateral incisors (7 and 10), maxillary canines (6 and 11), maxillary first premolars (5 and 12), maxillary second premolars (4 and 13), maxillary first molars (3 and 14), maxillary second molars (2 and 15), and maxillary third molars (1 and 16).
Representation of Wilson curve. The curve of Wilson is the across arch 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.
The word derives from mal- 'incorrect' and occlusion 'the manner in which opposing teeth meet'. The malocclusion classification is based on the relationship of the mesiobuccal cusp of the maxillary first molar and the buccal groove of the mandibular first molar. If this molar relationship exists, then the teeth can align into normal occlusion.
The dental arches are the two arches (crescent arrangements) of teeth, one on each jaw, that together constitute the dentition.In humans and many other species, the superior (maxillary or upper) dental arch is a little larger than the inferior (mandibular or lower) arch, so that in the normal condition the teeth in the maxilla (upper jaw) slightly overlap those of the mandible (lower jaw) both ...
Canine teeth, otherwise known as cuspids, each possess a single cusp, while premolars, otherwise known as bicuspids, possess two each. Molars normally possess either four or five cusps. In certain populations the maxillary molars, especially first molars, will possess a fifth cusp situated on the mesiolingual cusp known as the Cusp of Carabelli.
Molar relationship classification, observed when locating the mesial buccal cusp of the maxillary first molar and buccal groove of the mandibular first molar. (Institute of Dentistry, Aberdeen University) When discussing the occlusion of the posterior teeth, the classification refers to the first molars and may be divided into three categories:
