Extrusion Techniques-Clinical Applications of Modern Tooth Preservation Concepts and Their Comparison

Area of Science:

• Dentistry
• Restorative Dentistry
• Periodontology

Background:

• Insufficient tooth structure often compromises ferrule creation and biological width preservation.
• Restoring severely damaged teeth presents significant clinical challenges.

Purpose of the Study:

• To present and compare various tooth extrusion techniques.
• To evaluate their efficacy in creating adequate ferrule and managing biological width.

Main Methods:

• Orthodontic extrusion using elastics, magnets, or appliances.
• Surgical extrusion utilizing a vertical extraction system.
• Minimally invasive procedures with force-dependent extrusion distance.

Main Results:

• Extrusion techniques effectively save and restore teeth with compromised crowns.
• Satisfying treatment outcomes and low complication rates observed, including in the aesthetic zone.
• Medium-term follow-up data (up to 5 years) are promising.

Conclusions:

• Various extrusion techniques provide viable solutions for severely damaged teeth.
• These methods are predictable and yield favorable results.
• Long-term data are still needed to fully assess outcomes.
