The dental chair is used to position the patient so the oral cavity is in the desired position for the dentist to perform various dental procedures. The Dental chair is electromechanically operated. There are two dynamic functions, the base (up/down) and the back (forward/back). these functions are activated by use of either a foot switch or handoperated touch pad. The dental chair has the provision to mount additional dental equipment (over the patient delivery system refer to following sections for more information), therefore a stable base is included with the dental chair to accommodate such additions.
