Accuracy of the osseointegrated dental implants placement by a new method for obtaining surgical template for flapless guided surgery - in vitro study


The essential aspects in the dental implants placement include the protection of all anatomical structures aiming the best aesthetic-functional result. The literature demonstrates that there are two ways of transfer the virtually position of the planned implant to clinical situation, the static through surgical templates (surgical guides) and the dynamics through surgical navigation. The objective of this study is to validate a new method of obtaining a surgical template for flapless dental implant surgery using a intraoral scanner and additionally validate a new method of comparison of the accuracy of dental implants placement by digital transfer placed implants. Four dental implants will be placed by flapless surgery in polyurethane mandible with silicone gum simulation. Positioning of dental the implants will be achieved through the ImplantStudio software (3Shape, Copenhagen, Denmark). The 3D STL prosthesis model will be obtained through tomography and scanning (by intraoral scanner) of the prosthesis. It is expected that the new method of acquisition of the surgical template for installation of dental implants demonstrates a better accuracy mainly due to the decrease of variables to obtain them.
