[Methods aimed at lengthening the clinical crown: a review]
Parodontologie (Berlin, Germany)
|May 1, 1991
Summary
This review compares methods for clinical crown lengthening, highlighting surgical and orthodontic extrusion with fiberotomy as preferred techniques. Each approach offers distinct benefits and drawbacks for periodontal health.
Area of Science:
- Dentistry
- Periodontology
- Restorative Dentistry
Background:
- Lengthening the clinical crown is crucial for restorative procedures.
- Various surgical and non-surgical techniques exist, each with implications for periodontal tissues.
Purpose of the Study:
- To review and compare different methods for clinical crown lengthening.
- To discuss the advantages and disadvantages of each technique.
Main Methods:
- Review of surgical flap procedures (ostectomy, osteoplasty) to reduce alveolar crest height.
- Evaluation of root planing to prevent fiber reattachment.
- Analysis of gingivectomy, electrosurgery, intra-alveolar transplantation, and forced eruption.
- Assessment of orthodontic extrusion combined with fiberotomy.
Main Results:
- Surgical procedures like ostectomy and osteoplasty aim for a 3 mm distance to the reconstruction margin.
- Root planing can prevent the reattachment of surgically separated fibers.
- Gingivectomy, electrosurgery, and transplantation may have significant biological disadvantages.
- Orthodontic extrusion with fiberotomy is a conservative option for periodontal tissues.
Conclusions:
- Orthodontic extrusion with fiberotomy is a highly conservative method when applicable.
- Not all clinical crown lengthening needs can be met by orthodontic extrusion and fiberotomy alone.
- Surgical lengthening or orthodontic extrusion with fiberotomy are recommended based on the specific clinical situation.
