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. [1] A crown is typically bonded to the tooth by dental cement. They can be made from various materials, which are usually fabricated using indirect methods. Crowns are ...
The cost of the restoration is typically cheaper than composite restorations. Disadvantages of amalgam include poor aesthetic qualities due to its colour. Amalgam does not bond to tooth easily, hence it relies on mechanical forms of retention. Examples of this are undercuts, slots/grooves or root canal posts.
The root canal filling material (3, 4, and 10) does not extend to the end of the tooth roots (5, 6 and 11). The dark circles at the bottom of the tooth roots (7 and 8) indicated infection in the surrounding bone. Recommended treatment is either to redo the root canal therapy or extract the tooth and place dental implants.
A tooth is unsuitable for periradicular surgery if it does not have a good periodontal support or coronal seal. It must have enough structure to support restoration. Filling the root canals of the tooth from the crown (orthograde root canal therapy) should be the first treatment option to resolve inflammation caused by the tooth.
Ostensibly, then, for regeneration to occur, the root canal system must have been decontaminated and further access to microbial invasion must be prohibited. Regeneration of the bone has been demonstrated to occur, on average, at a rate of 3.2 mm² per month, and studies suggest that 71% of lesions have achieved complete resolution one year ...
Functionally, crown lengthening is used to: 1) increase retention and resistance when placing a fabricated dental crown, [2] 2) provide access to subgingival caries, 3) access accidental tooth perforations, and 4) access external root resorption.
