Because drooping of the transferred flap causes instability of the obturator prosthesis, maxillary reconstruction often incorporates a slit\u2010shaped oronasal fenestration. Although obturator prostheses for edentulous patients are stabilized with the help of oronasal slits, those for dentate patients are unstable because of flap mobility, resulting in a harmful lateral force exerted on the abutment teeth, causing dislodging of the denture. This report evaluates the benefits of a movable obturator prosthesis for a 60\u2010year\u2010old dentulous patient with maxillary sinus carcinoma. The patient underwent left\u2010sided total maxillectomy, and the defect was reconstructed with a slit\u2010shaped fenestration using a rectus abdominis flap. A conventional obturator prosthesis was inserted; however, drooping of the flap caused instability of the obturator, resulting in nasal regurgitation and fracture of the clasp. To solve this problem, we designed an obturator prosthesis with a movable connection consisting of a ball attachment (patrix) in the metal base and a socket (matrix) in the obturator, which acted as a stress breaker against the harmful force exerted by the flap. Application of this movable obturator prosthesis was a useful solution for a compromising situation created by the surgical procedure. No clinical disorders were observed at the 3\u2010year follow\u2010up.<\/jats:p>","DOI":"10.1111\/jopr.12199","type":"journal-article","created":{"date-parts":[[2014,8,4]],"date-time":"2014-08-04T18:24:14Z","timestamp":1407176654000},"page":"254-259","source":"Crossref","is-referenced-by-count":4,"title":["Fabrication
