ABSTRACT:
An improved dental handpiece holder supports a handpiece in the region from the rear end of the grip portion to the tail-stock portion. A front gripping holder portion prevents movement in the horizontal direction, a rear gripping holder portion prevents a forward tipping moving, and the front and rear gripping portions co-act to prevent movement of the handpiece in the axial direction. The front gripping portion is provided with three separate portions, one on the left hand wall and two on its right hand wall. The two supporting portions on the right hand wall are spaced axially apart from one another, and the single supporting portion on the left hand wall is located in a axial position intermediate that of the opposing two portions. Right and left supporting portions in the rear gripping portion support the tail-stock of the handpiece. A brim extending from the upper wall of the right hand rear supporting portion extends tangentially upward and to the left and facilitates the proper removal and replacement of the handpiece. The holder may be supported with respect to the backrest of a treatment chair holding a supine patient such that a dental surgeon seated in front thereof can conveniently remove and replace the handpiece held by such a holder in a conventional pen-grip manner. A second receptacle may be added to the holder for holding a second handpiece in a similar manner.
