Abstract
A combined dental drill and anchor pin for use in the field of denistry. Restoration techniques, involving the use of anchor pins for the retention and reinforcing of dental support structures as well as for various mechanical appliances used in the field of orthodontics, are facilitated by combining the drill and anchor pin in a single structure thereby eliminating separate drilling and pin insertion steps.
