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 ...
Root canal procedure: unhealthy or injured tooth, subsequent creation of an access cavity with a dental handpiece, cleaning and shaping the root canals with an endodontic file, and restoration with gutta-percha filling and a crown Removing infected pulp during a root canal procedure
Pivot tooth with a ferrule. The pivot tooth [1] [2] is a fixed dental prosthesis used to rebuild a tooth.It is a type of crown-root foundation [], but it is an independent supplement and usually consists of a pin or peg and a full crown [3] permanently connected (i.e., without cement) and placed in the patient's oral cavity during a single visit.

A root canal is the naturally occurring anatomic space within the root of a tooth.It consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root.
In mature teeth, root canal treatment is usually performed Non-emergency: removal of loose fragment (following gingivectomy, surgery or via orthodontics), root canal treatment and restoration with post-retained crown In extreme cases (such as a vertical fracture), tooth may need to be extracted 6–8 weeks: clinical and radiographic examination
After endodontic therapy has been executed, or re-executed, successfully, and the canals can no longer provide a nutrient-rich habitat for microbes, [31] the issue of bone healing comes into focus. Ostensibly, then, for regeneration to occur, the root canal system must have been decontaminated and further access to microbial invasion must be ...
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. Periradicular surgery is only considered if the inflammation persists after conventional root canal treatment.
When extracting lower wisdom teeth, coronectomy is a treatment option involving removing the crown of the lower wisdom tooth, whilst keeping the roots in place in healthy patients. This option is given to patients as an alternative to extraction when the wisdom teeth are in close association with the inferior alveolar nerve , and so used to ...
