Navigation surgery, or surgical navigation systems, play an important role in accurate and effective surgical procedures. Imaging is often integrated into these systems using CAS (computer-assisted surgery) technology, making surgery significantly safer in most cases. CAS was first developed in the 1980s by neurosurgeons and ENTs, but the technology has a substantially wide variety of applications in the medical field today. One of the most notable applications is within the field of dental health, or more specifically, during periodontal surgery. Dental implants, for example, are reported to have a lower failure rate when done with CAS technology versus traditional placement techniques. Surgical navigation systems help make surgical procedures less invasive and therefore reduces the risk of potential complications. In implant dentistry, surgeries that once required a flap to be made to expose the alveolar ridge for implantation of the screw can now be done with a small or even no incision.
