ABSTRACT:
An aseptic sheath for dental handpieces by the use of which the handpieces are eliminated as a possible source of transmission of microbial diseases. The sheath is formed of suitable resilient thermoplastic sheet material, preferably by vacuum forming, in a shape which corresponds to that of the particular handpiece with which it is to be used, e.g., to provide communicating spaces for substantially completely enclosing the head, neck and handle of a contra-angle handpiece. In use, the handpiece is inserted into the sheath by spreading normally overlapping edges of the sheath which extend longitudinally over at least the length of the handle-receiving portion to provide access for the handpiece to the sheath interior. After insertion is completed,the edges are released to snap back over the handpiece due to the resiliency of the sheath-forming material to substantially completely enclose the handpiece therewithin. After use, the handpiece is removed from the possibly contaminated sheath which is then discarded. The handpiece is ready for subsequent use in a new sheath. It is not necessary to disinfect the handpiece, such as by autoclaving, which has been found to affect the performance of the handpiece.
