Comparison of Mechanical Properties of CAD/CAM-Milled and Selective Laser-Melted Ti-6Al-4V for Dental Superstructures.

Abstract

PURPOSE:

To determine whether selective laser melting (SLM) is suitable for the fabrication of dental superstructures.

MATERIALS AND METHODS:

Mechanical properties of Ti-6Al-4V, manufactured with SLM or numerically controlled milling, were evaluated and compared.

RESULTS AND CONCLUSION:

Both groups showed a mechanical strength greater than 500 MPa and an elongation greater than 2%, as required by the International Organization for Standardization 22674 standard. However, a reduced ductility was observed for SLM samples.
