For dentists who were trained without computers and planning software, the introduction of any sort of digital technology can be met with reservation. Clinicians had to weigh the benefits of a new technique versus the cost and time involved in making it an effective investment. In low- and middle-income countries, the introduction of guided implant surgery is still in a nascent state. The procedures that fall into this category merge patients' data, both clinical and radiographic, to better visualize and guide access to the target site. Guided implant surgery is a minimally invasive, reproducible technique that substantially reduces the risk of injuring critical anatomical structures. Previously published data on guided implant surgery are limited and contain outdated methodology. In this review, the authors introduce the benefits, general principles and updated clinical workflow for guided dental implant surgery.
CPD/Clinical Relevance: Guided implant surgery is a reproducible technique that results in predictable implant placement.
Article
At the end of 19th century, the discovery of X-rays led to the development of a non-invasive clinical technique to assess the internal anatomical structures. By the late 1970s, advancements in the field of technology allowed clinicians to view three-dimensional images of tomographic scans. These images were about 100 times more sensitive than conventional radiographs. Later, software was introduced that could guide a clinician's probe to a target point chosen on the three-dimensional scans. The first surgical navigation unit, called the ‘Viewing Wand’, was used in 1992 in the field of neurosurgery to plan the procedure and, in real time, navigate the surgery.1 This significantly reduced the chance of adverse outcomes for the patient and offered improved clinical safety.2 This resulted in a paradigm shift and surgeons no longer needed to expose a patient to a knife to know what was underneath. Guided surgery became the standard of care in neurosurgery in early 2000. It was only time before guided surgery paved its way in implant dentistry.
