Dental implants are also used in orthodontics to provide anchorage (orthodontic mini implants). Orthodontic treatment [ 13 ] might be required prior to placing a dental implant. An evolving field is the use of implants to retain obturators (removable prostheses used to fill a communication between the oral and maxillary or nasal cavities). [ 12 ]
In dentistry, a crown or a dental cap is a type of dental restoration that completely caps or encircles a tooth or dental implant. A crown may be needed when a large dental cavity threatens the health of a tooth. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown.
Full-porcelain dental materials include dental porcelain (porcelain meaning a high-firing-temperature ceramic), other ceramics, sintered-glass materials, and glass-ceramics as indirect fillings and crowns or metal-free "jacket crowns". They are also used as inlays, onlays, and aesthetic veneers. A veneer is a very thin shell of porcelain that ...
The crown is usually visible in the mouth after developing below the gingiva and then erupting into place. If part of the tooth gets chipped or broken, a dentist can apply an artificial crown . Artificial crowns are used most commonly to entirely cover a damaged tooth or to cover an implant.
In dentistry, an abutment is a connecting element. [1] This is used in the context of a fixed bridge (the "abutment teeth" referring to the teeth supporting the bridge), partial removable dentures (the "abutment teeth" referring to the teeth supporting the partial) and in implants (used to attach a crown, bridge, or removable denture to the dental implant fixture).
Crown to root ratio is the distance from the occlusal/incisal surface of the tooth to the alveolar crest in relation to the length of root within the bone. The minimum ratio of crown to root is considered to be 1:1, although the most favourable is a crown:root of 2:3. As the proportion of tooth supported by bone decreases, the lever effect ...

Because crowns are wider, the contour of the crown is said to emerge (get wider as it ascends). In this facial view, it is desirable that the full emergence occur under the gum line (subgingivally) rather than above the gum line (supragingivally). The vertical dimension between the implant platform and the gingival margin is termed running room.
