Each tooth can be described as having a mesial surface and, for posterior teeth, a mesiobuccal (MB) and a mesiolingual (ML) corner or cusp. [1] An occlusal view of a complete maxillary denture. The green line, indicating the dental midline, is the defining line when it comes to mesial-distal direction. The blue arrow, which indicates a mesial ...
Molar distalization is a process in the field of Orthodontics which is used to move molar teeth, especially permanent first molars, distally (backwards) in an arch. This procedure is often used in treatment of patients who have Class 2 malocclusion . [ 1 ]
The distal root is generally straighter, although both often have a slight distal curvature. The heights of contour on the mesial and distal contact the adjacent teeth and are located at the junction of the occlusal and middle thirds of the crown. The mesial view shows a slight tipping of the crown to the lingual.
On anterior teeth, they are located on the mesial and distal borders of the lingual surface; on posterior teeth, they are located on the mesial and distal borders of the occlusal surface. Triangular ridges are those that project from the cusp tips of premolar and molars to the central groove.
The offset lies at an angle to the mesio-distal axis of the tooth, and causes the mesial portion of the central groove to be located further buccally than the distal portion. This buccolingual shift correlates with a relative difference in size between the mesial and distal cusps on these teeth - the mesiolingual cusp is larger than the ...
Compared to the tooth's mesial view of the cervical line, the distal cervical line is slightly more cervical by close to a millimeter. [15] There may be a developmental groove present for all or most of the length. [16] The distal view of the lateral incisor fits into the geometric shape of a triangle. [14]
Of the various ways of preparing the graft recipient site, Edel described using two vertical incisions, mesial and distal to the teeth at which the zone of keratinized tissue was intended to be widened. [1]
CEJs differ from tooth to tooth in terms of their anatomy. The curvature of the CEJ is greatest on anterior teeth due to the narrow profile of these teeth. [6] On the anteriors, the distal aspect's curvature is usually one mm lower than the mesial aspect. Posterior teeth have flatter CEJ curvatures on the inter-proximal surfaces in comparison ...
