Dual milling technique for manufacturing monolithic complete dentures with 3D-printed occlusal surfaces: A dental technique.

Abstract

This technical report described a digital approach that utilized computer-aided design and computer-aided manufacturing (CAD-CAM) workflows, integrating digital design, selective laser melting (SLM) metal 3D-printing, and a dual milling process to fabricate monolithic complete dentures with metal occlusal surfaces. The dual milling technology ensured accurate occlusion and minimized the risk of assembly errors. This technique is indicated for patients with severe occlusal wear in acrylic denture teeth by substituting metal for the occlusal surfaces.
