摘要：
A dental instrument includes at least one removable or replaceable dental tip. The dental instrument includes a spring actuated collet and collar housed internally within a handle. The handle includes a handle center affixed to a center rod and a grip portion housing the collet and collar and a handle center affixed to a center rod. The center rod is affixed to the collet. The collet includes spring fingers that are biased radially inward by the collar to retain the dental tip. When the grip portion of the handle is rotated about a longitudinal axis of the handle relative to the handle center, camming surfaces associated with the grip portion and the handle center cause translational movement along the longitudinal axis to engage or disengage the collar from the collet.
