RESUMEN

Unfavorable relationships between the residual edentulous ridge, pontic, and gingival papilla may compromise the definitive result of a restoration. Different procedures have been described and developed to improve the relationship between esthetics and functionally acceptable fixed partial dentures. This article describes a unique pontic design as well as the application of pressure during insertion of the pontic to achieve proper tissue displacement. Controlled pressure enhances the interdental papilla and creates the illusion of pontics emerging from the soft tissue, providing the restoration with a natural-looking effect.

SUMMARY

A conservative method for residual ridge modification using controlled pressure has been suggested. The technique described uses a ridge lap pontic with circumferential pressure applied on the edentulous ridge during placement of the restoration, produced after scoring the definitive cast. A gradual and controlled pressure transformed an unfavorable tissue configuration, without free space between the soft tissue and restoration. This tissue contact prevents visible plaque accumulation and tissue inflammation. Furthermore, the applied pressure caused soft tissue displacement in an attempt to create the illusion of the pontic emerging from the tissue and the formation of "pseudo" interdental papillae.
