An adjustable drilling guide, removably mountable to a patient's teeth, having
a guide block with at least one stent for guiding a dental drill is disclosed.
In a first embodiment, the guide block has a plurality of guide holes disposed
at differing angles which may receive a stent for precise drilling at the selected
angle. If minor variations need be made, the stent may be moved to a second or
third of the guide holes to adjust the angle. In a second embodiment, three distinct
stents are formed directly in the guide block allowing for drilling at up to three
different angles. A third embodiment has a stent which is pivotable about a pivot
point within the guide block, allowing drilling at any angle within the arc of
the pivot. The guide block may be fitted to a model of the patient's teeth prior
to installation into the mouth to ensure proper fit.
