Abstract

Apparatus is provided that includes a dental implement, which is shaped so as to define a lumen therethrough, a distal end of which lumen opens through at least one distal opening on a distal end of the dental implement; and a lateral external surface, at least a portion of which is shaped so as to define a screw thread that extends until the distal end of the dental implement. Other embodiments are also described.
