Sagittal Discrepancies of Intraoperative Results between 2D and 3D Planning in Orthognathic Surgery: A Series of 44 Cases

Pre-surgical planning in orthognathic surgery is a process of vital importance for obtaining satisfactory results for both the clinician and the patient. There are different planning methods, among which 3D software is one of the most important. These allow precise observation of the movements of bone and soft tissue structures, which until recently could not be predicted. Despite its advantages, many specialists continue to plan using the 2D method. The aim of this paper is to present the discrepancies between 2D and 3D preoperative planning and the intraoperative results of 44 patients undergoing bimaxillary orthognathic surgery and, together with this, to expose the variables that possibly influence the occurrence of these differences.
