Abstract (AI)
Within the limitations of this in vitro study, the manufacturing technique affected the mechanical properties of the zirconia materials. AM zirconia material showed lower Vh and FS values than M zirconia. Additionally AM zirconia demonstrated adequate bond strength with dental ceramic.
Key Findings
1
Additively manufactured (AM) zirconia demonstrated adequate bond strength with dental ceramic despite lower mechanical properties.
2
Additively manufactured (AM) zirconia exhibited lower Vickers hardness (Vh) than milled (M) zirconia.
3
Additively manufactured (AM) zirconia exhibited lower flexural strength (FS) than milled (M) zirconia.
4
Manufacturing technique (additive manufacturing vs milling) affects mechanical properties of dental zirconia in vitro.
5
Study is an in vitro pilot with acknowledged limitations regarding its findings.
Research Object
Dental zirconia manufactured by additive manufacturing (AM) and by milling (M)
Research Subject
