Among removable devices, eruption guidance appliances are used for early orthodontic treatments in order to intercept and prevent malocclusion problems. Commercially available eruption guidance appliances, however, are symmetric devices produced using a few standard sizes. For this reason, they are not able to meet all the specific patient\u2019s needs since the actual dental anatomies present various geometries and asymmetric conditions. In this article, a computer-aided design-based methodology for the design and manufacturing of a patient-specific eruption guidance appliances is presented. The proposed approach is based on the digitalization of several steps of the overall process: from the digital reconstruction of patients\u2019 anatomies to the manufacturing of customized appliances. A finite element model has been developed to evaluate the temporomandibular joint disks stress level caused by using symmetric eruption guidance appliances with different teeth misalignment conditions. The developed model can then be used to guide the design of a patient-specific appliance with the aim at reducing the patient discomfort. At this purpose, two different customization levels are proposed in order to face both arches and single tooth misalignment issues. A low-cost manufacturing process, based on an additive manufacturing technique, is finally presented and discussed.<\/jats:p>","DOI":"10.1177\/0954411917742945","type":"journal-article","created":{"date-parts":[[2017,11,21]],"date-time":"2017-11-21T07:57:58Z","timestamp":1511251078000},"page":"54-66","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":18,"title":["Design and manufacturing of patient-specific orthodontic appliances by computer-aided engineering techniques"],"prefix":"10.1177","volume":"232","author":[{"given":"Sandro","family":"Barone","sequence":"first","affiliation":[{"name":"Department of Civil and Industrial Engineering, University of Pisa, Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paolo","family":"Neri","sequence":"additional","affiliation":[{"name":"Department of Civil and Industrial Engineering, University of Pisa, Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandro","family":"Paoli","sequence":"additional","affiliation":[{"name":"Department of Civil and Industrial Engineering, University of Pisa, Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Armando Viviano","family":"Razionale","sequence":"additional","affiliation":[{"name":"Department of Civil and Industrial Engineering, University of Pisa, Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,11,21]]},"reference":[{"key":"bibr1-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1007\/s10439-009-9659-4"},{"key":"bibr2-0954411917742945","first-page":"28","volume":"1","author":"Bergersen EO.","year":"1984","journal-title":"Funct Orthod"},{"key":"bibr3-0954411917742945","first-page":"17","volume":"2","author":"Bergersen EO.","year":"1985","journal-title":"Funct Orthod"},{"key":"bibr4-0954411917742945","first-page":"163","volume":"15","author":"Migliaccio S","year":"2014","journal-title":"Eur J Paediatr Dent"},{"key":"bibr5-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1177\/0954411916636919"},{"key":"bibr6-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1177\/0954411912474741"},{"key":"bibr7-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1002\/cnm.2839."},{"key":"bibr8-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2007.05.018"},{"key":"bibr9-0954411917742945","first-page":"121","volume":"9","author":"Pileicikiene G","year":"2007","journal-title":"Stomatologija"},{"key":"bibr10-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9290(97)00009-2"},{"key":"bibr11-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1243\/09544119JEIM485"},{"key":"bibr12-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1007\/s11517-006-0075-8"},{"key":"bibr13-0954411917742945","first-page":"6100","author":"Citarella R","year":"2012","journal-title":"Open Mech Eng J"},{"key":"bibr14-0954411917742945","doi-asserted-by":"publisher","DOI":"10.2174\/1874155X01206010115"},{"key":"bibr15-0954411917742945","first-page":"8","volume":"4","author":"Armentani E","year":"2010","journal-title":"Open Mech Eng J"},{"key":"bibr16-0954411917742945","first-page":"V01AT02A052","volume-title":"ASME international design engineering technical conferences and computers and information in engineering conference","author":"Tilli J"},{"key":"bibr17-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-45781-9_42"},{"key":"bibr18-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1016\/j.medengphy.2010.03.009"},{"key":"bibr19-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1177\/0954411912463869"},{"key":"bibr20-0954411917742945","doi-asserted-by":"publisher","DOI":"10.1016\/S0889-5406(97)80022-4"},{"key":"bibr21-0954411917742945","unstructured":"exocad.
