Rehabilitation of the patients with maxillectomy defects presents a challenge in restoring the lost form, function and speech. Maxillary interim obturators in prosthetic reconstruction of the defects are often complicated with lack of adequate retention, stability, and support. This case report presents the simplified approach, to rehabilitate a case of sub-total maxillectomy due to squamous cell carcinoma of maxillary sinus, using a closed hollow bulb obturator prosthesis fabricated with a \u201cU\u201d loop and a modified buccal flange for enhanced retention of the prosthesis.<\/jats:p>","DOI":"10.4103\/0975-7406.163561","type":"journal-article","created":{"date-parts":[[2015,8,31]],"date-time":"2015-08-31T09:06:21Z","timestamp":1441011981000},"page":"S782-S785","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":4,"title":["A simple method of enhancing retention in interim hollow bulb obturator in a case of an acquired palatal defect"],"prefix":"10.4103","volume":"7","author":[{"given":"S.","family":"Karthikeyan","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, Vivekanandha Dental College for Women, Tiruchengode, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Balu","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Vivekanandha Dental College for Women, Tiruchengode, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V.","family":"Devaki","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Vivekanandha Dental College for Women, Tiruchengode, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Ajay","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Vivekanandha Dental College for Women, Tiruchengode, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R2-20250923","doi-asserted-by":"crossref","first-page":"108","DOI":"10.1016\/0022-3913(81)90021-4","article-title":"A surgical interim prosthesis","volume":"45","author":"Frame","year":"1981","journal-title":"J Prosthet Dent"},{"key":"R4-20250923","doi-asserted-by":"crossref","first-page":"560","DOI":"10.1016\/0022-3913(84)90347-0","article-title":"An interim obturator prosthesis with duplicated teeth and palate","volume":"52","author":"Kouyoumdjian","year":"1984","journal-title":"J Prosthet Dent"},{"key":"R5-20250923","doi-asserted-by":"crossref","first-page":"619","DOI":"10.1016\/0022-3913(89)90577-5","article-title":"Modifying a surgical obturator prosthesis into an interim obturator prosthesis.
