Summary

Dental implants and prostheses are costly and can damage teeth. This case study shows restoring a fractured incisor below the gum line using root extrusion and a custom crown, preserving natural tooth structure.

Area of Science:

  • Dentistry
  • Restorative Dentistry
  • Prosthodontics

Background:

  • Dental implants and prostheses offer solutions for missing teeth but present significant cost barriers for many patients.
  • These restorations can also be detrimental to adjacent healthy teeth and surrounding soft tissues.
  • Restoring severely fractured teeth, especially those extending below the gingival cuff and alveolar crest, poses a clinical challenge.

Observation:

  • A patient presented with a complicated incisor crown-root fracture extending significantly below the gingival cuff and alveolar crest.
  • The fracture involved critical tooth structure, making conventional restoration methods difficult.

Findings:

  • A novel approach utilizing remaining tooth tissue was employed for the restoration.
  • The procedure involved root extrusion to reposition the fractured tooth segment coronally.

  • A cast post, diaphragm, and core were fabricated, followed by the placement of a porcelain crown.

    • Implications:

    • This technique offers a viable, potentially more conservative alternative to tooth extraction and replacement with implants or prostheses.
    • Preserving natural tooth structure can lead to better long-term outcomes and patient satisfaction.
    • The described method provides a valuable case study for managing complex crown-root fractures in anterior teeth.
