A modified technique for single-step border molding

Abstract

The sectional and the single-step are techniques for border molding. Even though the sectional technique is routinely taught in dental schools in the United States, and is followed by a large number of general dental practitioners, it is not without disadvantages. Common problems associated with the sectional technique include its time-consuming nature and the difficulty in mastering it because of the short manipulation time of the impression compound modeling plastic. Single-step border molding, however, presents advantages; for example, fewer insertions of the tray for border molding are necessary, and development of all borders simultaneously avoids the propagation of error. This article presents a simplified technique for performing single-step border molding using visible light-polymerizing tray material.
