Summary
This study presents a rapid orthodontic extrusion protocol using intense forces and fiberotomy, offering a simpler alternative to surgical crown lengthening for exposing more dental tissue.
Area of Science:
- Dentistry
- Orthodontics
- Periodontology
Background:
- Restorative and prosthetic treatments often require increased clinical crown height.
- Surgical crown lengthening can be invasive and time-consuming.
Purpose of the Study:
- To detail a protocol for rapid orthodontic extrusion.
- To evaluate tissue migration following this protocol in 10 cases.
Main Methods:
- A 4-week active phase utilizing forces >300g.
- Weekly circumferential supra-crestal fiberotomy with root-planning.
- A subsequent 4-week passive stabilization phase.
Main Results:
- Assessment of dental, hard, and soft tissue migration.
- Evaluation of treatment outcomes over 8 weeks.
Conclusions:
- The described protocol is a viable, simpler alternative to surgical crown lengthening.
- It offers benefits in treatment simplicity, brevity, and achieving desired dental tissue exposure.
- Partial periodontal tissue migration was observed but deemed acceptable.
