“…For the purpose of facial surgery planning, various software packages have been developed, such as Dolphin, TIOPS1, Orthographic and Quick Ceph2, 3D Implant CMF and Dentofacial Planner. However, the prediction process is still mostly based on freehand planning, as the current software packages for surgery planning are still not particularly accurate3–4. Furthermore, most of these software packages base the soft tissue prediction on the ratios of the mean soft tissue movement relative to the movement of the hard tissue2.…”

Background Recent advances in diagnostic imaging and associated software have enabled the transformation of anatomical structures into finite element (FE) models facilitating computerized facial modelling. The work presented employs personalized imaging data of facial anatomical structures for use in planning and predicting the outcome of maxillofacial surgery. The current process relies on either freehand planning and/or commercial twodimensional (2D) and three-dimensional (3D) surgical planning software packages, but the validity of these software packages has been questioned. In this paper, the finite element technique was used to predict the outcome of maxillofacial surgery.

“…With the recent advance in three-dimensional (3D) imaging, computer-assisted surgical planning and simulation are popularly used in orthognathic surgery for comprehensive analysis of craniofacial complex and enhanced predictability of surgical outcomes [ [1] , [2] , [3] , [4] , [5] , [6] ]. Surgical splints and guides can be generated by using computer-aided design and computer-aided manufacturing (CAD/CAM) technique based on the virtual planning to facilitate orthognathic surgery [ [7] , [8] , [9] , [10] ].…”

Background Previous computer-generated splints were designed and produced without modification than the traditional occlusal splints, which did not facilitate surgeon's intraoperative judgment in the single-splint two-jaw orthognathic surgery. Modifications of the digital occlusal splint can be achieved using computer-aided design and computer-aided manufacturing (CAD/CAM) software. This study reported the design, clinical application and validation of a novel CAD/CAM occlusal splint. Methods The maxillary and mandibular segments were fixed into the final occlusal splint and moved to the planned position according to the 3-dimensional simulation. The composite occlusal splint has 4 orthogonal bars to facilitate intraoperative assessment of the dental and skeletal midline, facial soft tissue midline, occlusal plane, upper tooth show, facial symmetry and facial bone position. To validate the surgical outcome, 5 parameters including pitch, roll and yaw rotations, midline deviation and chin position were measured on the virtual plan and the postoperative cone-beam computed tomography images to quantify the difference. Results The results showed no significant differences in the 5 parameters between the simulation and postoperative images. The root-mean-square difference between the conventional splints and CAD/CAM surgical splint ranged from 0.18 to 0.31 mm by superimposition of the two image models. All patients were satisfied with the treatment outcomes. Overall, this novel occlusal splint is ideal for verification of the maxillomandibular position during surgery. Conclusion The novel composite occlusal splint provided useful and informative check to verify the maxillomandibular complex (MMC) position and facial appearance in single-splint two-jaw orthognathic surgery.
