Guided surgery in implantprosthetic rehabilitation

The prosthetic result as well as the long– term success in implant–prosthetic rehabilitation depends on a series of factors such as: position, number of implants, surgical technique, bone and mucosal offer, and others. Usually, free hand surgery does not allow in all the cases to place implants in best position from the prosthetic and biomechanical point of view. Due to the development of scanning technologies and three–dimensional printing, the planning of final results allows the printing of surgical guides, to ensure the most accurate position of dental implants [1,2]. The comparative analysis of conventional and guided implant placement methods has demonstrated significant advantages in favor of guided surgery. However, with the application of additional maneuvers in the treatment (impression, scanning, planning, template fabrication), a number of disadvantages and errors were observed that may affect both, the treatment and results.
