A Technique to Guide and Measure the Reduction of a Processed Mandibular Complete Denture for Resilient Soft Liner

Abstract

A resilient soft liner (RSL) has been used in processed complete dentures but controlling its thickness has always been a challenge because of uneven reduction of the denture’s intaglio surface. Use of a thermoplastic vacuum-formed template and an endodontic K-file, as guides, for the reduction of a processed mandibular complete denture to receive RSL is described in the present report. A processed mandibular complete denture is prepared by reducing its borders and drilling holes in its surface. A thermoplastic sheet adapted to the intaglio surface and an endodontic K-file with rubber stop adjusted to the desired dimension are used as guides to the reduction procedure and allows intermittent measuring of the reduced areas. This technique helps in reducing the processed denture’s intaglio surface in a controlled manner thus maintaining the strength of the denture base and effectiveness of soft liner. It also makes the application of resilient soft liner a cost and time effective maneuver
