Drilling device for implant cavities in oral surgery, with an angle piece (2), which receives a drill (1), which protrudes through a sliding drill bushing (3), which is held on a drill bushing template (5) adapted to the jaw (4) of a patient to be treated. The sliding drill bushing (3) is of essentially cylindrical design and has an internal diameter which exceeds an external diameter of the drill. The sliding drill bushing (3) is provided with a slide (7), which guides the angle piece in directions parallel to the axis of rotation of the drill (1). …<??>Method for producing a drill bushing template for implant cavities, in which the remaining teeth of a patient are prepared for parallelism of clinical crowns, an anatomical impression is taken, a model is cast, and a template element (20) consisting of curable plastic is built up on the basis of the model. At a position intended for an implant cavity (23), a bore is made through the template element (20) and a precision sleeve (27) is secured in the bore, which precision sleeve is adapted to a sliding drill bushing (3). …<IMAGE>… |
