Abstract
|
|
|
The past techniques of clinical crown lengthening procedures had disadvantages in certain cases. The apically positioned flap with bone recontoring causes attachment loss and esthetic deformities. Also, slow, forced eruption of teeth, using
orthodontic
force causes the coronal shift of free gingival margin and alveolar crest.
Therefore, a new technique of clinical crown lengthening procedures has been developed and reported. The technique combined rapid tooth movement and incision of the supracrestal gingival fibers. The procedure was performed in a patient with
severe
destruction of a tooth crown.
The present study was used the rapid tooth movement with fiberotomy.
Eruptive tooth movement was activated by simple orthodontic appliance.
During the forced eruption, intrasulcular incision was performed to serer the crestal fibers.
The present technique prevented coronal shift of the gingiva and the attachment apparatus during the orthodontic extrusion.
Therefore, this technique overcomed the need of osseous surgery.
