[X-ray study of patients at the stage of preparation for prosthesis by using dental maxillary implants]

The paper deals with the possibilities of using the data of X-ray studies--computed tomography and orthopantomography--in planning the surgical stage of implantation for preprosthetic correction of the upper denture. Examination of 23 patients has yielded the data showing what estimation of the size of an image obtained by the "Denta Scan" programme provides.
