“…8,34 Another disadvantage is the higher radiation dosage to which the patient has to be exposed due to specific CT scanning criteria, comparing with a regular CT scan for diagnosis. 3,34 These limitations might be overcome by future technological developments.…”

“…In secondary reconstructions, the virtual model is then used to create the implant design either by mirroring from the contralateral side or by generation curves based on the anatomical region with CAD-based devices. 3 The ideal cranial implant material would fit the cranial defect and achieve complete closure, (e.g., radiolucent for postoperative imaging), resistant to infections, strong to biomechanical processes, easy to shape, not expensive, and ready to use. 1,[25][26][27]…”

“…Digitally mirroring the healthy maxilla to the abnormal side helps guide the ideal skeletal geometry. 1,3 In maxillofacial surgery, this has been successfully implemented in the form of interchangeable jigs that constrain operative placement to a specific area. As a result, planned osteotomies and bone movements are accurately defined and tailored to patient anatomy.…”

“…34 Thus, by using specific software, it is possible to calculate the exact contours, angles, length, and morphology of the new mandible. 3 Digitally mirroring the healthy mandible to the abnormal side helps guide the ideal skeletal geometry. Then, by using 3D-printed biomodels, there is an enhancement in the positioning of mandibular segments, shorter operative time by no intraoperative repeated bending and adapting of plates, and also less chances of postoperative plate breakage.…”

Craniomaxillofacial Trauma & Reconstruction

Craniomaxillofacial reconstructive surgery is a challenging field. First it aims to restore primary functions and second to preserve craniofacial anatomical features like symmetry and harmony. Three-dimensional (3D) printed biomodels have been widely adopted in medical fields by providing tactile feedback and a superior appreciation of visuospatial relationship between anatomical structures. Craniomaxillofacial reconstructive surgery was one of the first areas to implement 3D printing technology in their practice. Biomodeling has been used in craniofacial reconstruction of traumatic injuries, congenital disorders, tumor removal, iatrogenic injuries (e.g., decompressive craniectomies), orthognathic surgery, and implantology. 3D printing has proven to improve and enable an optimization of preoperative planning, develop intraoperative guidance tools, reduce operative time, and significantly improve the biofunctional and the aesthetic outcome. This technology has also shown great potential in enriching the teaching of medical students and surgical residents. The aim of this review is to present the current status of 3D printing technology and its practical and innovative applications, specifically in craniomaxillofacial reconstructive surgery, illustrated with two clinical cases where the 3D printing technology was successfully used.
