A stationary, mains electricity (AC-powered) device assembly designed to provide dental staff with the necessary utilities/amenities to deliver dental treatment to a patient. The utilities/amenities are typically compressed air, water, suction, electricity, table top or bracket table surfaces, cuspidor, gas, and sometimes the dental light. This is a fixed-position system (i.e., not mobile) which incorporates an instrument unit for dental instrument provision. The patient examination/treatment chair is typically integrated as part of this system.
A pneumatically-powered device designed to make available the necessary instruments/equipment and power to deliver dental treatment to a patient. It consists of a platform for the display of a selection of powered dental instruments (e.g., motor handpiece, scaler, suction, air/water spray), sometimes with a control panel for setting various operating parameters; it may be portable or mounted. The device is commonly referred to as a dental unit or dental operative unit and is intended to be operated by a healthcare professional in a medical facility.
