Material Type: Harder materials benefit from the sharper silicon carbide, whilst softer components and finer finishes are better reached with aluminum oxide. Some producing abnormalities were being also discovered which could have compromised strength. The Triplex samples tested here weren't as strong as claimed in a prior research.
