Three-dimensional (3D) printing models are extensively recommended in contemporary oral and maxillofacial surgeries to predict treatment outcome and prognosis, reduce operative time, improve peri-operative and post-operative function, and minimize wound exposure duration, complications, and postoperative morbidity. The current application of 3D models and templates from an oral and maxillofacial surgeons perspective also extends to patient education, assists direct visualization of anatomic structures, to perform incisions and surgical resections, assessment of craniofacial bony defects, temporomandibular joint (TMJ) fixation devices, and reconstruction plate adaptation. Stereolithography (SL), fused deposition modeling (FDM), photopolymer jetting (PJ), and laser sintering (LS) are commonly preferred three-dimensional printing technologies in oral and maxillofacial surgery. Presently 3D printed biologically active scaffolds are recommended for bone tissue repair in craniofacial defects, soft tissue regeneration, particularly in the maxillofacial region. Despite several advantages, the application of 3D printing is limited due to its potential cost, the expense of 3D printing devices, and challenges in handling materials and software. Thus the present review was carried to elaborate on various clinical applications of 3D printing in Oral and Maxillofacial surgery with a brief on 3-Dimensional Printing techniques, bioprinting of structures along with their accuracy, reliability, and future potential.
