Purpose: The aim of the paper is to present the own method of design and manufacturing of surgical guides on the basis of cone beam computed tomography (CBCT) scans and three-dimensional models of teeth and soft tissue obtained from impressions or intraoral optical scans, which are possible to use during surgical implant placement. Design/methodology/approach: The method of designing and manufacturing of surgical guides was developed on the basis of real clinical data coming from patients with severe bone deficit qualified for implantological treatment. The model of bone and virtual model of soft tissues were combined together. The project of the prosthetic restoration imposed on the virtual model of the bone was used to plan the position of the implants. The final surgical guide was manufactured with the use of a CNC milling machine. Findings: The method enables planning of the implant position based on two combined models of the bone and soft tissues and allows to design and manufacture a surgical guide. Thus, it becomes possible to place the implants in the bone of the patient during a surgical procedure in a preplanned position. Practical implications: Thanks to the method of designing and manufacturing of surgical guides a range of clinical tasks in preparation of the guides is restricted to registration of the intraoral situation, taking of CBCT scans of the bone and determination of the type of the prosthetic restoration. Properly made surgical guides allow to shorten the time of the surgical procedure and carry it out in a minimally invasive manner. Originality/value: This paper presents an original method of designing and manufacturing of surgical guides. This allows for precise planning of the position and the number of implants and the transfer of these data into the mouth of a patient during the surgery without the use of commercially available closed software.
