Occlusion, in a dental context, means simply the contact between teeth.More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest.
In orthodontics, a malocclusion is a misalignment or incorrect relation between the teeth of the upper and lower dental arches when they approach each other as the jaws close. The English-language term dates from 1864; [ 1 ] Edward Angle (1855–1930), the "father of modern orthodontics", [ 2 ] [ 3 ] [ need quotation to verify ] popularised it.
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 ...
Conversely, a deficient VDO will appear as though the patient's mouth has collapsed, and the chin appears too close to the nose; in essence, the patient would be over-closing their mouth because there would not be enough wax on the wax rims to maintain the proper vertical dimension of occlusion.
The mandibular third molar is the tooth located distally from both the mandibular second molars of the mouth with no tooth posterior to it in permanent teeth. In deciduous teeth, there is no mandibular third molar. For this tooth, there are great variances among third molars, and a specific of a third molar will not hold true in all cases.
In dentistry, the linea alba (from Latin 'white line') [1] is a horizontal streak on the buccal mucosa (inner surface of the cheek), level with the occlusion (biting plane). ). It usually extends from the commissure to the posterior teeth, and can extend to the inner lip mucosa and corners of the mo
This study found that open-mouth smiles can easily be mistaken for a sign of fear or contempt—the two lowest rated smiles were both pretty toothy. Better to go with no teeth, or just show your ...
Edge-to-edge articulation is when opposing front teeth meet along their incisal edges when teeth are in maximal intercuspal position. [16] In Posselt's envelope this happens in ICP as the incisors of the mandible slide past the cingulum of the upper incisors to meet the biting edge and continue to maintain tooth contact as mandible protrudes ...
