A surgical device for identification of a surgical site of interest, such as a craniofacial or dental site (root apex of an identified tooth), and a method for using the device is provided. The device includes a perimeter bar and a plurality of intermediate cross bars arranged in a grid structure. The device can be used during a surgical procedure requiring enhanced precision, such as during an endodontic surgical procedure, by positioning the device next to a patient's tooth and capturing a CBCT image, the CBCT image being used to identify a drilling location. The device can be repositioned alongside the patient's tooth, and used to identify an accurate drilling position.
