Abstract
The invention relates to a device for axial retention of a dental instrument shank and for transmitting the rotational driving of the instrument. The device is arranged in a head of a contra-angle or handpiece. The shank has an annular groove in which at least one stud is able to engage radially, and a flat permitting rotational driving of the shank. The rotational movement is communicated by an output pinion of a mechanical transmission assembly coupled to a drive motor and arranged in a sleeve joined to the head of the contra-angle. The device is formed by a shaft traversed axially by the instrument shank, at least one elastic lever, and at least one pin. There is cooperation of the pin or pins with the flat provided on the instrument shank.
