Examination/treatment chairs designed to facilitate dental examination, treatment, and/or minor surgical procedures. These chairs are typically adjustable up to a height that allows the healthcare staff to perform procedures while standing; the chairs usually include head- and armrests, a reclining back that may be tilted from a vertical to a horizontal or near-horizontal position, and rotating capabilities to facilitate examination and/or treatment. The chairs may be mechanically operated or hydraulic or electrically powered; some chairs can be programmed for several standard positions. Dental examination and/or treatment devices (e.g., lights, irrigation) may be partially or completely attached as integral components of the chair or may stand separately as self-supported, wall-mounted, or ceiling-suspended units (i.e., dental delivery units); dental delivery systems including a suspended patient chair are also available.
