Abstract

The disadvantages of an open-type hollow obturator include difficulty in polishing and cleaning of the internal surface, food accumulation in the hollow obturator and inability to obtain support from the superior aspect in the defect area. This article describes an easy time-saving procedure that uses visible light-activated denture base materials as a reline material to close an open type interim obturator. This procedure can be used successfully for both late stage interim obturators and/or for correcting leakage problems for patients who wear definitive obturators. (J Prosthet Dent 1997;78:327-9.)

    Reline the tissue side of the interim obturator base with chairside soft reline material, which will act as an impression material.

  • 2.

    Lubricate the remainder of the acrylic resin base of the obturator with a thin layer of petroleum jelly.

  • 3.

    Box the relined obturator with a 2 ¾ inch in height adhesive paper (Nacs Corp., Oberlin, Ohio).

  • 4.

    Pour the cast for the tissue surface of the obturator with fast set stone mixed with plaster at 1 to 1 ratio (Fig. 1) .

  • 5.

    Separate the obturator carefully from the working

Summary

An easy and time-saving procedure to reline and to close an open-type interim obturator using VLC resin has been described. This procedure can be used for both a late stage interim obturator and/or to correct leaking problems for patients who wear definitive obturators.
