Summary

Minor connectors for removable partial dentures should avoid interdental embrasures. Relocating them to the lingual aspect of abutment teeth can prevent gingival attachment loss and protect susceptible sites.

Area of Science:

  • Dentistry
  • Prosthodontics
  • Periodontology

Background:

  • The minor connector of a removable partial denture is typically placed in the interdental embrasure.
  • Recent evidence indicates a higher probability of gingival attachment loss on the proximal aspect of teeth.
  • Interdental embrasure placement of minor connectors may expose vulnerable gingival areas.

Purpose of the Study:

  • To present a rationale for an alternative design for removable partial denture minor connectors.
  • To propose locating the minor connector on the lingual aspect of the abutment tooth.
  • To avoid placing minor connectors in the interproximal area to mitigate risks of gingival recession.

Main Methods:

  • Review of current prosthodontic practices.
  • Analysis of evidence regarding gingival attachment loss.

  • Design proposal for alternative minor connector placement.

    • Main Results:

    • Interdental embrasure placement of minor connectors is associated with increased risk of gingival attachment loss.
    • Lingual placement offers a potentially safer alternative for abutment teeth.

    Conclusions:

    • Relocating minor connectors from interdental embrasures to the lingual aspect of abutment teeth is recommended.
    • This design modification can help prevent gingival attachment loss and protect susceptible periodontal sites.
