What is a guided implant surgery and why we may need that? To do guided implant surgery you need three things: a patient with an edentulous area, a cone beam scan with or without a radiographic guide, and a model — either stone or virtual — on which the surgical guide will be made. The first step is to do a thorough oral and medical exam to be certain that the patient is not only a candidate for guided implants, but for implants in general. In some cases, a removable appliance or bridge may be the best restoration for what the patient needs. With some systems, the length of the drills, guides, handles, and handpieces may be too large for a patient with a limited opening. (Fig. 1) You must be certain that the patient is scanned by a system that works with the implant planning software you are using and the lab that will ultimately fabricate the guide.
