ABSTRACT:
A dental positioning device for facilitating the accurate placement of a drill guide on teeth in order to drill spaced apart aligned bores in which a dental retaining splint is to be received. The positioning device is formed of a continuous wire including a U-shaped top section lying in a horizontal plane with an anchoring pin vertically extending from one arm of the top section, and a loop depending from the other arm thereof, the loop also lying in a horizontal plane. The anchoring pin is inserted through the axial opening of a first tubular member upwardly extending from a drill guide and further inserted into a first hole drilled in the tooth. The loop fits around a second tubular member also extending upwardly from the drill guide and spaced from the first tubular member. The axial opening in the second tubular member is then used to drill a second hole accurately spaced apart from the first hole. After the positioning device and drill guide are removed, a dental retaining splint is then inserted into the drilled holes. The structure of the positioning device permits easy removal thereof from the teeth, where the positioning device can be used to remove the drill guide therewith. The bight portion of the U-shaped top section provides a visual indication as to the proper position of the drill guide.
