Inventor(s)Eley; Christopher D. (722 N. 13th St., Apt. #905, Milwaukee, WI 53233)
AbstractSystems and methods for positioning the oral cavity of a dental patient are described. A method includes: providing: a pivotable chair with: a reclinable back; and a headrest connected to the reclinable back, the headrest including: a bracket for attaching the headrest to the reclinable back; and a pad connected to the bracket, the pad including an internal perimeter that defines a hole through which a prone patient's nose and mouth can protrude so that the prone patient's oral cavity can be reached from below the prone patient; locating the dental patient on the pivotable chair in a prone position so that the dental patient's nose and mouth protrude through the hole; pivoting the pivotable chair; and reaching into the dental patient's oral cavity from below the dental patient. The systems and methods provide advantages in that back and neck stress on the dentist is reduced while dental prophylaxis is facilitated.
