crown lengthening การใช้

A fiberotomy is performed after crown lengthening and is easily performed by the general dentist.
If the patient is unhappy with the height of their teeth and a Dahl approach cannot be tolerated then crown lengthening may be appropriate.
An alternative to surgical crown lengthening is orthodontic forced eruption, it is non-invasive, does not remove or damage the bone and can be cost effective.
In situations where the margin cannot be placed apically enough to provide for proper retention of the prosthetic crown on the prepared tooth structure, the tooth or teeth involved should undergo a crown lengthening procedure.
It is because of this increased risk of failure inherent in the use of post and core restorations that, when all of the independent failure rates of the many procedures needed for the restoration of the tooth are considered together ( endodontic treatment, crown lengthening ( when indicated ), post and core and prosthetic crown ), the patient is sometimes advised to have the tooth extracted and an implant placed.
