In-lab simulation of CAD/CAM milling of lithium disilicate glass
The contact angle values were statistically similar for the CAD/CAM, SiC, WS and DB groups prior to HF etching, but no statistically significant difference was found among between the milled and in-lab simulated etched specimens (p = 1.000) (Table 1 and Fig. 1).However, the POL group presented a significantly lower contact angle pre and …

Milling vs Grinding
Grinding specializes, mainly sticking to metalwork to deliver a top-tier finish. Speed vs. Precision: Milling is your speedy option, taking off material at a faster rate. Grinding is the slow and steady one, aiming for flawless finishes. Accuracy: Both are highly accurate, but grinding gets extra points for ultra-fine finishes and tight tolerances.

Reduce Over-Milling
Reduce Over-Milling. In all of the years of CAD/CAM dentistry, this discussion has always happened. "Over milling" is where the burs remove more material on the intaglio surface so that the restoration will seat without binding. The "over mill" is dependent on the prep surface, the thickness of the spacer, the bur geometry, and the ...
