DynaFlex (www.dynaflex.com) has been working with Cadent for several years on transferring .stl files to their laboratory to make appliances. The feedback on the process has been very positive especially as it relates to Hawleys. DynaFlex has also developed a process to make banded appliances from these scans as well. DynaFlex charges $8.75 per arch to accept and print each arch.
