Background and study aims
An implant-supported fixed dental prosthesis (FDP) can be used to replace both teeth and gum tissue. The consequences of incorrect implant position may become evident in the short and long term and are not correctable without the removal of the implant in many instances. The use of computed tomography (CT), including low radiation dosage cone beam computed tomography (CBCT), and CAD/CAM (computer-aided design/computer-assisted manufacturing) technology have created the possibility for preoperative implant planning and proper communication with the patient, surgeon and the prosthodontist. Dynamic navigation is real-time coordination of the surgeon’s hands and eyes by 3D visualization of the implant site preparation with high magnification achieved through dedicated hardware and software consistently tracking and matching the real patient with the virtual patient during the surgery. Dynamic guided surgery or navigation allows the surgeon a real-time visualization of the implant site while the drills are in function without any template hiding the surgical field. Full guidance is possible, deviations from the predetermined plan can be assessed in “real time” and the related adjustments of position can be made at any time during the surgery in case any event occurs. The aim of this study is to evaluate deviations from pre-operative digital planning between implants placed by a dynamic navigation system.

Who can participate?
Patients aged 18 years or older who need an implant-supported fixed dental prosthesis (FDP) in the anterior and premolar area of the upper and lower jaw

What does the study involve?
Dental implants are positioned by means of a dynamic navigation system and immediate post-operative CBCTs are performed in order to assess the accuracy of implant placement.
