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 ...
In the temporomandibular joint, the initial mouth opening occur by rotation, within the inferior cavity of the joint. [14] The TMJ rotates around a fixed axis within the condyle, with no antero-inferior translation. [14] The maximum jaw opening with this rotation movement is indicated as 'R' on the Posselt's envelope of motion.
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.
Teeth can belong to one of two sets of teeth: primary ("baby") teeth or permanent teeth. Often, "deciduous" may be used in place of "primary", and "adult" may be used for "permanent". "Succedaneous" refers to those teeth of the permanent dentition that replace primary teeth (incisors, canines, and premolars of the permanent dentition).
Mandibular fracture, also known as fracture of the jaw, is a break through the mandibular bone.In about 60% of cases the break occurs in two places. [1] It may result in a decreased ability to fully open the mouth. [1]
Open bite is a type of orthodontic malocclusion which has been estimated to occur in 0.6% of the people in the United States. This type of malocclusion has no vertical overlap or contact between the anterior incisors. [1] The term "open bite" was coined by Carevelli in 1842 as a distinct classification of malocclusion.
P eople have been talking up mouth-taping lately on TikTok and Instagram as a home remedy for snoring, insomnia, dry mouth, and other sleep-related issues—and the trend seems to be sticking ...
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.
