[Scanner placement guide and surgical guide in implantology].

Abstract

The pre-surgical investigation may provide added information by the wearing of a detection cad-can indicating the axes of the future implants at the time of the cad-can examination. This stent is made, using a polymerised director mounting, equipped with radio-opaque detectors in aluminium or zinc oxyphosphate sealing cement. The resulted illustration facilitates the concentration between the surgeon and the prosthetist in the definitive choice of the site of implantation. The plaster model, used for the making of the detection cad-can, is used to transfer this information. In the clinic, the latter is supported by a surgical stent. This guide includes: an indexed stabilising portion on the remaining teeth or portions of edentated crest not involved in the surgery; guiding tubes with a diameter of 2.1 mm, made of infiltrated aluminium according to the INCERAM* procedure. The detection cad-can and surgical stent unit permit a correlation between the preimplant investigation phase and the surgery.
