Milling
Milling (medicine)
Milling (pronunciation: /ˈmɪlɪŋ/) is a term used in various fields of medicine, particularly in pharmacology and dentistry.
Etymology
The term "milling" originates from the Old English mylen, which is derived from the Latin mola, meaning "mill" or "grinder". In a medical context, it refers to the process of grinding or crushing substances.
Pharmacology
In pharmacology, milling is the process by which solid forms of drugs are reduced to a fine powder. This is often done to increase the surface area of the drug, thereby enhancing its dissolution rate and bioavailability. The process can be carried out using various types of mills, including ball mills, hammer mills, and fluid energy mills.
Dentistry
In dentistry, milling refers to the process of creating dental restorations, such as crowns and bridges, from solid blocks of ceramic or composite resin materials. This is typically done using a computer-aided design/computer-aided manufacturing (CAD/CAM) system, which allows for precise control over the shape and size of the restoration.
