For replacing a single missing tooth with implant, is there a difference between the traditional and the new techniques for placing implants in relation to accuracy and restoration longevity

Two different computer-based surgical guides will be used and tested: full guides and partial guides. These guides are based on computer 3D analysis of jaw bone and digitally planning for ideal implant position. Each patient will receive a cone beam CT scan of the implant site. The scan is a standard procedure required for implant planning, and every patient from the intervention and control groups will receive the same scan. The different surgical guide types are produced differently in the laboratories, and there will be no additional clinical appointment or involvement for the participating patients. According to the ideal implant position, surgical guides will be produced by 3D printing. The full guides are related to an international implant company that designs (via commercial software) and produces surgical guides to control all the surgical steps and implant placement. The partial guides are designed by an open source software and produced by commercial laboratories. The partial guides control only the first step of implant surgery, which is the pilot bone drilling. This step is completed only by one drill (pilot drill), and the generated bone hole will be used to guide the rest of the bone drills without the use of the guide. Each implant will be randomly allocated to one of the test guides or the traditional guide. The implant surgery normally takes about 1 to 2 hours. All the surgical and restorative steps will be completed under supervision of periodontics and prosthodontics dental specialists who are familiar with all the implant placement protocols. To standardize the treatment, the involved clinicians will be calibrated and will follow a data collection form to ensure consistent data gathering for each step of treatment.
