The standard technique of implant placement uses the free-hand approach. In this, after the necessary evaluations, the surgeon places the implant into the bone using structures adjacent to the surgical site as references. An additional device whose sole purpose is to direct the position and angulation at which the implant should be inserted and placed is not used, as is done in guided surgeries. It is for this reason this technique is also known as brain-guided surgery. Navigation in surgery acts as a measuring tool and information centre for the surgeon by providing him/her with the correct information during the surgical procedure : The location of the surgeon’s anatomical target, the route to reach it safely, the current location of the surgeon in relation to the surrounding anatomical structures and the precise location and angulation at which the implant has to be positioned. Dynamic navigational surgery is a surgical modality in which surgical instruments are accurately tracked and targeted to a pre-planned location within the surgical field. This is dependent of the co-ordination of intra-operative position of instruments with the pre- operative radiographic images of the patient’s anatomic site. It allows for precise localization and aids the surgeon’s orientation intraoperatively within the surgical field.
