Summary

A collarless metal ceramic denture offers excellent aesthetics by omitting the metal collar on the buccal side. This approach is a viable option for dental restoration when appearance is paramount.

Area of Science:

  • Dentistry
  • Prosthodontics
  • Esthetic Dentistry

Background:

  • Fixed partial dentures (FPDs) are common restorative solutions.
  • Esthetic demands in dentistry are increasing.
  • Traditional metal-ceramic FPDs can present esthetic challenges due to the metal collar.

Observation:

  • A case report details a collarless metal-ceramic FPD.
  • Preparations were made at a slightly supragingival level.
  • The buccal portion of the abutments lacked a metal collar.

Findings:

  • The collarless design resulted in an excellent esthetic appearance.
  • This design effectively concealed the metal substructure on the visible surfaces.
  • The supragingival preparation level facilitated placement and potentially hygiene.

Implications:

  • Collarless metal-ceramic FPDs are a viable esthetic restorative option.
  • This technique addresses patient concerns regarding the "black line" at the gumline.
  • Further studies could explore long-term stability and material interactions.
