Effects of additive manufacturing technology and build angle on surface characteristics and microbial adhesion of 3D-printed dental zirconia: a laboratory study.

ABSTRACT:

Background

Microbial colonization on 3D-printed zirconia restorations may aggravate plaque accumulation and periodontal inflammation. While additive manufacturing (AM) parameters significantly influence surface roughness and morphology, evidence regarding their impact on bacterial adhesion remains unclear. This study investigated the effects of AM technologies and build angles on the surface characteristics and initial microbial adhesion of 3D-printed zirconia.

Methods

Zirconia discs were fabricated using material jetting (MJ, 10 μm layer thickness) and digital light processing (DLP, 30 μm layer thickness) technologies with three build angles (0°, 45°, and 90°), respectively (n = 25 per group). The surface topographic features and roughness were analyzed using scanning elect
