A fast, accurate and easy method to position oral implant using computed tomography
This paper presents a simple method and new material which allow transferring results of surgical planning — such as the implant fixture axis — to the surgical site. This method is based on drilling a linear guide in a resin splint corresponding to the fixture axis. A simple mechanical setup links the Computed Tomography (CT) data set with the drilling machine. Since the optimal fixture axis is determined with a software interface, it can be transferred as a linear guide to the resin splint with the drilling machine. Technical validation demonstrates that the accuracy of the method is 0.2 mm in translation and 1 degree in rotation. These results provide a high level of accuracy and clinical validation has begun with several patients. The results for the patients are very satisfactory.
