Abstract: A method and device for cleaning abutment members of a dental implant in which a relatively rigid support member carries a cleaning element into a position around the lingual surface of the abutment member to be cleaned whereafter the cleaning element can be rubbed against the abutment member to effect the cleaning. The cleaning element can be fixed to the support member in which case, the support member is manipulated to achieve the cleaning of the abutment member by the cleaning element. Alternatively, the support member can be removed from the mouth after the cleaning element has been put into place around the abutment member whereafter cleaning of the abutment member is achieved by the cleaning element itself.

Abstract: A removable and disposable extension for a light guide of a dental curing light in which a hollow empty body having a calibrated aperture therein is detachably fitted on the rigid light guide so that the aperture faces the optical glass in the light guide. The hollow body is opaque to light and provides a pathway for light from the optical glass to and through the aperture. The aperture is calibrated so as to be of relatively small size compared to the optical glass to permit a relatively narrow beam of light to exit from the aperture. The extension permits substantially instantaneous spot curing of a composite between a laminate and a tooth to preserve their relative position when other operations are carried out.
