The article presents two procedures for zirconia treatment - milling and grinding. Milling is a standard manufacturing procedure used, among others, in dentistry (CAD / CAM systems), grinding is used when the material is already cured, and the dentist must perform the grinding treatment of the places that clog the patient's soft tissue.

Ball Milling - an overview ScienceDirect Topics. Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force.In this process, graphite (precursor) was breakdown by randomly striking with grinding ...

Milling Early history - quern stones. Milling is the process by which cereal grains are ground into flour. Traditionally, and in some parts of the world to this day, this would have been accomplished by grinding the grain between two stones, a lower, stationary stone called the quern stone and an upper, mobile stone called the handstone.

2.1. Materials.

Superior machines ceramic workpieces in both the "green" (unfired) and sintered (fired) states. Sintered workpieces are much harder and denser than green ones and must be machined with diamond grinding tools. Instead of using traditional grinders, the shop often uses standard CNC milling machines and machining centers for these grinding operations.

Nonetheless, the excessively high hardness of monolithic zirconia (1200 VHN) [3] restorations caused severe wear to enamel (270-360 VHN) [4] antagonists and to the milling tools during processing ...

Marginal fit is critical for the success and longevity of a dental restoration. Zirconia crowns can be fabricated either chair-side, in a dental laboratory or in a milling center; each can give different marginal fits results. However, discussion of the marginal fit of zirconia crowns when different fabrication methods are compared is lacking in the literature.
