Andrews' Six Keys (1972) to normal (or optimal) are a widely quoted set of static occlusal goals for tooth relationships in the intercuspal position: The distal surface of the disto-buccal cusp of the upper first permanent molar occludes with the mesial surface of the mesio-buccal cusp of the lower second molar.

2025年1月23日 · Mesial occlusion corresponds to the closure of the molars according to the 3rd Angle class - this is a sagittal malocclusion. At the same time, the mesial displacement of the crowns of the first chewing teeth by 0.5 of the width of …

2015年1月4日 · The primary occlusion has one of three possible anteroposterior molar relationships called steps or planes. The majority of children has a mesial step between the distal surfaces of the second primary molars (Fig. 6-1, A). The mandibular molars are situated more mesially than their maxillary counterparts, thereby forming a mesial step.

Occlusion in which the mandibular articulate with maxillary teeth in a position more anterior than normal. Synonym(s): anterior occlusion (2) , mesioocclusion . Medical Dictionary for the Dental Professions © Farlex 2012

Normal occlusion in primary teeth has the following characteristics: spacing between anterior teeth, primate spaces, low overjet and overbite, flush terminal plane molar relation, and ovoid arch form [3, 4]. The deviations in occlusion in primary dentition would be carried to succeeding permanent dentition and to a more pronounced degree .

2024年7月4日 · Mesial occlusion represents a pathology of occlusion in the sagittal plane, characterized by the following features: the upper canine is positioned behind the interdental space between the lower canine and premolar. About the causes and principles of treatment of mesial occlusion in the webinar Open and Mesial Occlusion. Etiology.

Nowadays the treatment of the mesial malocclusion among children is an important orthodontic problem. According to researches’ data there is a growing number of patients with mentioned pathology in the latest decade. Moreover, the amount of patients with severe skeletal forms of mesial occlusion also increases.

2015年1月5日 · Occlusion is the contact relationship between the maxillary teeth and mandibular teeth when the jaws are in a fully closed (occluded) position, as well as the relationship between the teeth in the same arch.

2015年1月9日 · This movement of the mandibular molar may correct an end-to-end molar relationship (normal for the mixed dentition) into a normal molar relationship in the permanent dentition (i.e., the mesial lingual cusp of the maxillary first molar occludes in the central fossa of the mandibular first molar and the mesial buccal cusp of the maxillary first ...

A malocclusion in which the mandibular arch articulates with the maxillary arch in a position mesial to normal; in Angle classification, a Class III malocclusion. Synonym (s): mesial occlusion (2) .
