UNITED STATES PATENT APPLICATION Of: ROBERT H. MEIBAUER For: DENTAL PROPHYLAXIS DEVICE AND PROCESS ABSTRACT OF THE DISCLOSURE There is disclosed a dental prophylaxis device which may be electrically or battery powered and which comprises in combination a pair of spaced tynes disposed on a housing provided with an axial cavity, stationary support means on the housing in the vicinity of the base of the tynes and oscillating support means located on the housing between the bases of the tynes. The oscillating support means is supported on a cylindri- cal sleeve disposed in the housing cavity and cooperates with an oscillating drive shaft powered by driving means located in a second housing to which the first mentioned housing is removably connectable, A dental tape or floss having a non-elastic loop at one end which is supported on the oscillating support means and an elastic loop at the opposite end which is supported on the stationary support means spans the space between the ends of tynes and reciprocates between the tynes when the oscillating support means is in motion. The process disclosed comprises contacting dentition surfaces with a dental tape or floss having a thread segment with a non-elastic loop at one end and an elastic loop at the oppo- site end, reciprocating the thread segment over the dentition surfaces while expanding and contracting the elastic loop in response to the application of tensile force to the floss and absorbing the tensile force imparted thereto when it encounters resistance and the elastic loop expands.
