This report investigates the application of the virtual twin concept and advanced digital technologies, specifically 3-dimensional (3D) scanning, computer-aided design (CAD), and additive manufacturing techniques, toward the development of a custom palatal obturator for managing a chronic oronasal fistula in an 18-month-old male cat. Despite more than 3 prior surgical attempts, the fistula remained unresolved. The approach involved the CAD of the palatal obturator. This involved creation of a 3D model of the palatal lesion, enabling precise simulation, planning, and customization of the obturator. After placing the obturator, complete remission of clinical symptoms indicated a significant improvement in quality of life. The techniques described demonstrate considerable efficacy in closing palatal defects. The integration of virtual twin modeling and 3D technologies provides a minimally invasive treatment option, offering a promising alternative to the surgical approaches by enhancing visualization, design precision, and procedural predictability.<\/jats:p>","DOI":"10.1177\/08987564261495733","type":"journal-article","created":{"date-parts":[[2026,10,9]],"date-time":"2026-10-09T12:38:40Z","timestamp":1791549520000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Computer-Aided Design of a Palatal Obturator in Treating Feline Oronasal Fistula: A Case Report"],"prefix":"10.1177","author":[{"given":"Tsung-Fu","family":"Hung","sequence":"first","affiliation":[{"name":"WeCare Animal Medical Center, Taoyuan City, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9012-7344","authenticated-orcid":false,"given":"Po-Jan","family":"Kuo","sequence":"additional","affiliation":[{"name":"National Defense Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cedric","family":"Tutt","sequence":"additional","affiliation":[{"name":"The Veterinary Dentist, Cape Town, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0604-0199","authenticated-orcid":false,"given":"Izzie Yi-Chin","family":"Tsai","sequence":"additional","affiliation":[{"name":"Dentistry and Oral Surgery Service, In-Asia Animal Hospital, Taipei, Taiwan"},{"name":"Veterinary Dentistry and Oral Surgery Group, TACS-Alliance Research Center, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,10,9]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.5326\/15473317-37-2-183"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-950X.2007.00249.x"},{"key":"e_1_3_2_4_2","volume-title":"Textbook of Small Animal Surgery","author":"Slatter D.","year":"2002","unstructured":"Slatter D.
