Why it matters for dental
Dental lab owners and prosthodontic specialists can now quantify how build orientation in multi-material inkjet printing affects both dimensional accuracy and flexural strength of complete dentures, informing capital-equipment decisions and in-house production protocols.
Key points
- Study evaluated three print orientations (0°, 45°, 90°) on multi-material inkjet-printed maxillary and mandibular complete dentures.
- Dimensional deviation was lowest (≤ 0.1 mm) when denture bases were printed flat (0°), while 90° orientation increased deviation to 0.3 mm and reduced flexural strength by 18 %.
- Occlusal surface trueness remained within clinical tolerance (± 0.2 mm) across all orientations, but intaglio surface adaptation was most affected by vertical builds.
- Authors recommend 0° orientation for production runs to balance accuracy, strength, and minimal post-processing, relevant for labs considering multi-material 3-D printing versus milled dentures.
