Abstract
An adjustable dental drill guide for locating and permitting the drilling of accurately spaced apart holes for receiving a dental retaining splint. The drill guide includes two telescopically arranged portions which can be secured together in a preselected extended position to form a composite rigid body member. A locating pin depends from the distal end of one of the portions for being received in a hole provided in a first tooth when the body member is disposed in a channel extending from the first tooth to at least one adjacent tooth. A drill bushing passes through the distal end of the other body portion and extends upwardly therefrom for guiding a drill during formation of a hole in an adjacent tooth. Preferably, the body portion provided with the locating pin is a bar, and the body portion provided with the drill bushing is a hollow member for slidably receiving the bar therein. In a modified form, the locating pin has a shoulder portion thereon for permitting the drill guide to pivot when associated with a track member.
