Traditional wires and brackets has been widely used
as orthodontic devices for long time. The metal wires and brackets
help to correct the position of teeth as well as fix the cavity.
However, metal brace wires have quite a lot limitations. Patients
wearing metal brace have many food restrictions and feel not
comfortable. Brushing and flossing are required to remove the
food debris frequently. Hence, clear plastic aligners have popped
up recently. Since the metal brace fabrication process has
associated with prolonged process time as a result of a long
workflow process starting from brace mold presentation to the
prosthesis execution. The growing of additive manufacturing
technology make it possible to develop complex structures and
shapes of dental brace. By combining 3D oral scanning, it is
possible to shorten the lead time of orthodontic treatment process.
This review, therefore, investigates the use of Digital Light
Processing (DLP) Additive Manufacturing Technology for plastic
dental brace development as a remedy to the problems associated
with the traditional methods. The study reveals that it is feasible to
fabricate these plastic braces utilising the DLP technology. DLP
technology is affordable and arguably able to produce dental
models with high levels of assurance and accuracy.
