A method for producing a drill assistance device for a tooth implant includes the process steps of, initially the taking of an x-ray picture of the jaw and the compilation of a corresponding measured data record; then a three-dimensional, optical measurement of the visible surfaces of the jaw and of the teeth and the compilation of a corresponding measured data record. The measured data records from the x-ray picture and the measured data records from the three-dimensional, optical image are correlated with each other. Based on the information that is now available the type and position of the implant relative to the adjacent teeth is planned and a drill template is produced which is attached to the neighboring teeth, thus making the exact drilling of the implant pilot hole possible.
