A review of the literature review set out to answer the following questions: Who uses 3D printing in maxillofacial surgery (MFS) and is it routine or not? What are the main clinical indications and what are the kinds of objects used? Are these objects printed by an official medical device (MD) manufacturer or made directly within the department or the lab? What are the advantages and drawbacks? A total of 297 articles from 35 countries were selected as relevant, the most represented country was the People's Republic of China (16%) and 2,889 patients were reported as benefiting from 3D printed objects. The most frequent clinical uses were dental implant surgery and mandibular reconstruction. The most frequently printed objects were surgical guides and anatomic models of which 45% were professionally printed. The main advantages were improvement in precision and reduction of surgical time. The main disadvantages were the cost of the objects and the time taken to manufacture when printed by the industry. The authors conclude that although 3D printed objects are easily available they will never replace a surgeon’s skill and should only be considered as useful tools.
