An interocclusal distance of 2-4 mm between rest position and intercuspal position. This is just the opposite of fiction. Inclination should be positive in this categary of teeth. If not, just enter the malposition in the dental records. This type of malocclusion may also be referred to as a crossbite. The resulting malocclusion may be minor and functional, or major malocclusions from traumatic bites to the cat's oral tissues.
Receding gums can be exacerbated by a faulty bite. The crown of the upper first molar must be angulated so that the distal marginal ridge occludes with the mesial marginal ridge of lower second molar.

If the gingival area of the crown is more lingually placed than the occlusal area, it is referred to as positive crown inclination.
Malocclusion can cause a number of health and dental problems. In breeds that have medium and long muzzles, the premolars should meet in a saw-toothed fashion. More technically, it is the relationship between the upper and lower teeth when they approach each other, as occurs during chewing or at rest. According to the American Association of Orthodontists, occlusion is the relationship between your upper maxillary and lower mandibular teeth as they come into functional contact, such as when you bite, chew or close your jaws together. You may need to have , , or facial x-rays. Thus made it possible for usand orthodontic mechanics. Clicking, crepitus and tenderness of the jaw should be noted as well.

But the creation of a normal standard, a typical relationship, a basis on which tostandard, a typical relationship, a basis on which to compare departures from the normal, was lacking. The goal of selective breeding is to mate one animal to another that has superior occlusion.
This is more prominent in the anterior teeth as the jaws and permanent teeth grow. This progression positions the cusp tips on a curve that isthe cusp tips on a curve that is directly related to the condylardirectly related to the condylar axis by a progressive series ofaxis by a progressive series of tangents. It is not considered a genetic or inherited defect. Retained Deciduous Teeth Retained upper canine tooth Normally the deciduous tooth's root is resorbed, making room for an adult tooth. The curvature of the arc wouldThe curvature of the arc would relate, on average, to part of arelate, on average, to part of a circle with a 4-inch radius.
The mesiobuccal cusp of the mandibular first molar occludes in the embrasure area between the maxillaryoccludes in the embrasure area between the maxillary second premolar and first molar. The long axis of canine fallows lateral walls of nose. Correction takes the form of extraction, crown amputation and direct pulp capping, or orthodontic movement.
