BDC Dental Unit

The BDC Dental Unit is a dental operatory system that supplies compressed air, water, vacuum, and electrical power to dental devices and accessories. It includes a patient chair, dentist element (tray table with 3-way syringe), assistant element (syringe, high-volume evacuator, saliva ejector), side cabinet, foot control, cuspidor, and dental operating light for use by trained dental professionals in clinical settings.

The BDC Dental Unit has similar core components and functions to the predicate A-dec 500: both provide air, water, vacuum, and electrical power; both use pneumatically controlled valves for air and water flow; both include a patient chair, delivery system, assistant arm, dental light, and cuspidor. Minor differences exist in patient load capacity (150 kg vs. 227 kg), chair height range, backrest/headrest adjustability, lift motor type (hydraulic vs. electric), and foot control style, but these do not affect fundamental performance or safety.

ISO 10993-5 (cytotoxicity), ISO 10993-10 (irritation and sensitization), EN/IEC 60601-1 (electrical safety), EN/IEC 60601-1-2 (electromagnetic compatibility), IEC 80601-2-60 (dental equipment safety), ISO 7494-1 and 7494-2 (dental unit performance), ISO 9168 (hose connectors), and ISO 16954:2015 (waterline biofilm treatment).

The subject device and predicate are substantially equivalent because they have the same intended use (supplying power and serving as a base for dental devices in clinical settings), identical design principles (pneumatic control of air/water, similar component architecture), and comparable technological characteristics across all material functions. The differences identified (patient load, chair height, motor type, foot control) are quantitative variations that do not alter the fundamental engineering approach, principle of operation, or basic safety profile, and the device meets the same applicable safety standards as the predicate.
