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.
