Magnetic extrusion technique for restoring severely compromised teeth: A case report

Area of Science:

• Dentistry
• Orthodontics
• Biomaterials

Background:

• Extensive dental damage often necessitates complex restorative procedures.
• Managing compromised teeth requires techniques that preserve tooth structure and periodontal health.
• Magnetic extrusion offers a potential alternative for extruding severely damaged teeth.

Observation:

• A cylindrical neodymium-iron-boron (Nd2Fe14B) magnet was affixed to the damaged premolar.
• A second magnet was integrated into a resin-bonded partial denture.
• The technique facilitated controlled extrusion of the tooth structure.

Findings:

• A 4.5-mm extrusion was achieved after three adjustments.
• The extruded tooth was prepared using a biologically oriented preparation technique, ensuring adequate ferrule.
• Restoration with a monolithic zirconia crown provided durable and aesthetic results.
• Follow-up at 18 months revealed no signs of soft tissue dehiscence, mobility, endodontic failure, or root resorption.

Implications:

• Magnetic extrusion is a viable conservative treatment for extensively damaged maxillary premolars.
• This technique preserves tooth structure and periodontal tissues, potentially avoiding extraction.
• Biologically oriented preparation and zirconia restorations ensure long-term functional and aesthetic outcomes.
