Our aim was to describe the process of manufacturing customized oral appliances with a new technique i.e. rapid tooling method. The appliance should ideally be custom made to match the teeth. An orthodontic patient, scheduled for conventional orthodontic treatment, served as a study subject. After a precise clinical and radiographic examination, the approach was to digitize the patient’s dental arches and then to correct them virtually by computer. Additive manufacturing was then used to fabricate a mould for a soft customized appliance. The mould was manufactured using stereolithography from Somos ProtoGen O-XT 18420 material. Casting material for the mould to obtain the final appliance was silicone. As a result we managed to create a customized soft orthodontic appliance. Also, the accuracy of the method was found to be adequate. Two versions of the described device were manufactured: one with small and one with moderate orthodontic force. The study person also gave information on the subjective patient adaptation aspects of the oral appliance. 5 9 2012 85 89 TODENTJ-6-85 1 10.2174/crossmark_policy opendentistryjournal.com benthamopen.com true Peer Reviewed Single blind Checked with iThenticate 2012-2-22 2012-4-12 2012-4-12 2012-5-9 http://creativecommons.org/licenses/by-nc/3.0/ 10.2174/1874210601206010085 1553505342 https://opendentistryjournal.com/VOLUME/6/PAGE/85/ https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-85/TODENTJ-6-85.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-85/TODENTJ-6-85.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-85/TODENTJ-6-85.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-85/TODENTJ-6-85.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-85/TODENTJ-6-85.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-85/TODENTJ-6-85.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-85/TODENTJ-6-85.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-85/TODENTJ-6-85.xml Int Orthod Vassura G 8 46 2010 Vassura G, Vassura M, Bazzacchi A, Gracco A.
