Abstract

This article presents an innovative workflow for fabricating monolithic complete dentures with a pink gingival-colored flange using 3-dimensional (3D) printing. The technique involves digital design, volume subtraction, and 3D printing of the prosthesis in 2 separate stages: a tooth-colored monolithic base and a pink gingival-colored flange. These components are assembled with high precision, ensuring superior esthetics while reducing time and material waste. The described method overcomes the assembly errors typical of conventional techniques and highlights the economic and practical advantages of integrating digital workflows with 3D printing technology.
