摘要：

The orthodontic appliances can be built in a great diversity of resin that could be classified by one of the criteria, in thermoplastic and therm set. This paper has as purpose to compare three resins used for orthodontic appliances, one thermoplastic and two therm set -Biocryl C (Scheu Biostar), Orthocryl (Dentaurum), Orthoplast (Vertex Dental)-from the mechanical properties respect such as surface hardness and indentation elastic modulus. We tested six specimens; two from each type of these resins. Each specimen was fixed on a support and they were tested with Nano Indenter G200 from Keysight (Agilent). We obtained as a result that the thermoplastic material has a lower elastic modulus than the other therm set.
