Managing severely compromised teeth—resulting from extensive subgingival caries, subgingival fractures, or severe cervical resorption—remains one of the most challenging dilemmas at the intersection of orthodontics, periodontics, and restorative dentistry.
In such clinical scenarios, exposing sound supragingival tooth structure is essential to achieve an adequate ferrule effect and respect the biological width (supracrestal tissue attachment), ensuring long-term structural integrity and periodontal health.
While surgical crown lengthening has traditionally served as the conventional solution, it often leads to irreversible alveolar bone removal, apical displacement of the gingival margin, and compromised pink aesthetics, particularly in the anterior aesthetic zone.
To overcome these anatomical and aesthetic limitations, orthodontic forced eruption provides a minimally invasive, tooth-preserving alternative.
However, conventional slow extrusion techniques typically promote the coronal migration of both the periodontal ligament and alveolar bone along with the root, requiring secondary resective surgery.
In contrast, rapid orthodontic extrusion applies intense vertical traction forces combined with localized surgical fiber-severing protocols to selectively move the tooth while minimizing supportive tissue migration.
This clinical study presents a standardized, systematic protocol for rapid orthodontic extrusion evaluated across clinical cases.
The treatment sequence comprises a 4-week active extrusion phase applying intense forces (>300 g), integrated with weekly circumferential supra-crestal fiberotomy (CSF) and root planing, followed by a 4-week passive retention period to ensure occlusal and tissue stabilization.
The findings demonstrate that this protocol predictably exposes sufficient coronal tooth structure for restorative and prosthetic rehabilitation within a remarkably short clinical timeframe.
By offering a straightforward, brief, and biologically sound technique, this research equips clinicians with a powerful protocol to preserve compromised natural dentition and elevate aesthetic and functional restorative outcomes.
