Light-Cured Record Base

In this method, trapezoid-shaped sheets of composite resin are placed on the master cast and cured with a visible light unit. No operator exposure to monomer is involved.

Preparation of the Master Cast

Deep undercuts are blocked out with pink baseplate wax and the cast is painted with the manufacturer’s recommended model release agent.
THE MASTER CAST IS NOT TO BE SOAKED IN WATER.

Light-Cured Method

A sheet of pink-fibered denture base material is placed over the cast and carefully adapted to the ridge and vestibular contours, taking care not to over-compress and inadvertantly thin the material. The cast is then placed into the curing unit for two minutes. The record base is then removed, placed on the turntable tissue side up, and cured for another two minutes.
