Summary

Forced eruption is a preferred dental procedure for restoring mutilated teeth, preserving bone and esthetics. This technique ensures adequate tooth structure for crowns by extruding the root, maintaining biologic width.

Area of Science:

  • Dentistry
  • Orthodontics
  • Restorative Dentistry

Background:

  • Crown lengthening is crucial for restoring teeth mutilated at or below the bone crest.
  • Forced eruption is advantageous over surgical bone removal, preserving biologic width and esthetics.
  • A minimum of 4 mm from the alveolar crest to sound tooth structure is required for crown construction.

Purpose of the Study:

  • To present a technique for calculating the post-orthodontic root-to-crown ratio.
  • To guide the assessment of root restorability before initiating forced eruption.
  • To ensure optimal restorative outcomes after crown lengthening procedures.

Main Methods:

  • A technique is proposed to calculate the root-to-crown ratio after forced eruption.
  • This calculation considers the coronal extent of sound tooth structure relative to the alveolar crest.

  • The method evaluates root restorability prior to orthodontic treatment.

    • Main Results:

    • The suggested technique allows for pre-treatment calculation of the final root-to-crown ratio.
    • It aids in determining the feasibility of restoring the tooth after forced eruption.
    • This predictive method supports informed treatment planning.

    Conclusions:

    • Forced eruption is a valuable technique for crown lengthening, preserving periodontal health and esthetics.
    • A pre-treatment assessment of the root-to-crown ratio is essential for successful outcomes.
    • The proposed technique facilitates predictable restorative treatment planning.
