Class I has normal molar occlusion but other teeth may have crowding or eruption over or under its intended place. Same as normal occlusion but characterized by crowding rotations and other positional irregularities. Maxillary canine is in between md canine and 1st premolar.

Teeth are aligned in Cusp Fossa relationship with their antagonist teeth. Class II occlusion occurs when the lower dental arch is posterior more towards the back of the mouth than the upper one. In order to better understand types of occlusion its been broken down into three categories.

Edward Angle who is considered the father of modern orthodontics was the first to classify malocclusionHe based his classifications on the relative position of the permanent MAXILLARY FIRST MOLARAngle. Class II Division I and II - Overbite. Proper occlusion is important for both dental and general health.

A class i occlusion is what is typically considered the ideal and least destructive occlusal relationship. Dental occlusion often rhymes with confusion discrediting many research protocols. The state of being occluded.

Nūtrō-klūzhŭn A malocclusion in which there is a normal anteroposterior relationship between the maxilla and mandible. To occlude the teeth is to align the upper and lower teeth as for chewing. This is the correct occlusion and it gives the person a well-balanced profile in the anteroposterior plane.

Angles Class I Occlusion mesiobuccal cusp of upper first permanent molar occludes with the buccal groove of lower first permanent molar. -Cusp of the maxillary cuspid canine occludes between the distal of the mandibular cuspid and the mesial of the mandibular first bicuspid. Class i is a normal relationship between teeth jaw and jaw.

The three classes according to Angles classification are as follows. Class I occlusion is also known as. The mesiobuccal cusp of the upper first molar occludes with the buccal groove of the lower first molar.
