Problems and Prospects of Using 3D Printing in the Manufacture of Orthodontic Appliances

Recent technological advances in the medical field are irrevocably changing the clinical work of dentists, from diagnosis to treatment plan approaches to orthodontic appliances. 3D printing of orthodontic appliances can be fully performed using a digital process, which has advantages for both the orthodontic team and the patient. Thus, the advantages include the possibility of digitalization directly during the treatment process. It should be noted that this technology has certain disadvantages and limitations. Its biggest issue is the cost of equipment and the dependence on binding can be problematic in the lower arch. In addition, limited alloys are available for printing. Cobalt-chromium alloys are the most used and approved materials for dental 3D metal printing.
