Types of Dental Chair Instrument Trays

Dental chair instrument trays come in various types, each designed to cater to different needs and preferences of dental professionals. These include the basic tray, mobile tray, over-the-patient tray, combination tray, and wall-mounted tray. Each type has its unique features, advantages, and disadvantages, allowing dental professionals to choose the one that best suits their practice and the specific procedures they perform.
