Rehabilitation of maxillectomy defect with obturator prosthesis
The acquired defects of the palate are created commonly surgical intervention of benign or malignant neoplasms. The size and location of the defect influence the level of difficulty in prosthetic rehabilitation. Surgical intervention creates anatomic defect which forms communication among the oral cavity, nasal cavity and maxillary sinus. The goal of prosthodontist is to rehabilitate missing oral and extra oral structures with restoration of normal anatomic and physiologic function. Prosthetic rehabilitation with obturator restores the oral structures and also acts as barriers between communications among the cavities.

Maxillary defects resulting from resection involving the maxilla pose unique surgical and prosthetic rehabilitation challenges. Such defects occur as a consequence of congenital malformations, trauma or surgical resection of tumors. Surgical reconstruction of large maxillary defect is seldom tried. The obturator is a prosthesis used to close maxillary defects to restore masticatory and phonetic functions. This clinical report describes prosthodontic management of a maxillectomy defect with obturator prosthesis.

This clinical report describes a comprehensive prosthodontic treatment of a young patient diagnosed with squamous cell carcinoma in hard palate. The treatment procedures included surgical removal of the tumor, immediate surgical plate and interim obturator. The surgical plate and interim prosthesis were fabricated using conventional polymethyl methacrylate resin material with retention derived from wrought wire clasps to the remaining natural teeth. The follow-up system revealed satisfactory results with no deterioration in the prosthesis.
Maxillary Obturator Prosthesis : Support and Retention Case Series
2016
An extensive intraoral maxillofacial prosthesis presents challenges to the clinician in many ways. The problems encountered include that of support and retention of the prosthesis. These problems arise due to unfavorable anatomical configuration of the defect. This unfavorable configuration may prompt the clinician to device alternate /additional means of support and retention. The aim of this case series is to review the conventional and unconventional means of support and retention for the maxillary obturator prosthesis.
Management of a Maxillectomy Patient by Definitive Obturator
International Medical Journal (1994)
Background: Prosthetic and surgical procedure can be applied to rehabilitate acquired palatal defect. The obturator pros-thesis as a part of prosthetic management are used for separation of oral and nasal cavities to allow adequate deglutition and articulation, support for the soft tissue to restore the midfacial contour in palatal defect cases. Clinical presentation: This clinical report describes a prosthetic approach to the rehabilitation of acquired palatal defect with definitive obturator prosthesis and its outcome. We set the artificial teeth in unilateral group function occlusal scheme and finally process the denture. Conclusion: Rehabilitation with obturator prosthesis is functional, reliable/safe, and easy to build.
Rehabilitation of Maxillectomy Case Wi̇th Conventional Retained Obturator Prosthesis: A Case Report
Atatürk Üniversitesi Diş Hekimliği Fakültesi Dergisi, 2018
Maxillary resection performed for removal of the tumor mass, leads to esthetic, phonetic, functional and important psychological problems for the patient. The primary aim of prosthetic rehabilitation is to close the maxillary defect and eliminate such problems by use of different bulb designs. An obturator is a treatment option for the defects after maxillary tumor surgery. In this article, rehabilitation with hollow bulb obturator prosthesis was explained for a patient subjected to maxillary resection because of tumor mass.
Cancers Review
The maxillofacial patient experiences a unique alteration in the normal oral/craniofacial environment and functions, which are the results of congenital, traumatic or surgical insults. Maxillofacial Prosthetics aimed to attain the optimal functions, such as speech and swallowing, and normalcy of surrounding structure. The provision of surgical obturator is one step in achieving normalcy, as it allows covering the deficiencies/defects to regain optimal/suboptimal functions immediately after surgical resection. This paper provides an overview on the designing principles, goals and role of surgical obturator in rehabilitating maxillectomy cases.
Definitive Obturator Prosthesis Fabrication For A Hemi Maxillectomy Patient -A Case Report
Defects of maxilla are created by surgery of benign or malignant neoplasms or by trauma. Oroantral communication are created by maxillectomy that causes impaired speech, difficulty in mastication and deglutition and facial disfigurement. Patients with small oro-antral and oronasal defects may be amenable to surgical closure, but patients with larger defects are rehabilitated by prosthodontic-means in the rehabilitation of such larger defects the prosthodontist plays an important role by fabricating obturators. Obturator is the prosthesis that is used to close a palatal defect for a dentulous or edentulous patient. A clinical report of fabricating a definitive obturator with a cast metal framework for an acquired maxillary defect is described in this paper. Thus, it provides improves the speech clarity, better masticatory efficiency, and quality of life of the patient.

Background: Maxillectomy defect causes an oro-nasal opening affecting oral functions; inability to chew and swallow disorders in phonation, aesthetics and psychological depression of patients. Obturator prosthesis can result improvement in oral functions by re-establishing oro-nasal separation. Objectives: The study was done to investigate the effects of maxillary defect form, size, and remaining maxillary teeth on oral functions in post-maxillectomy patients. Materials and Methods: The study was conducted over 16 post-maxillectomy patients, age (mean±SD = 37.56±13.07 years) ranged from 18 to 70 years, male 9(56.20%) and female 7(43.80%), partially dentate, treated with obturator prosthesis at the prosthodontic department of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. All patients had continuously worn the obturator prostheses for at least 3 months during the study. Data of each patient were recorded on the basis of size and form of maxillary defect, and remainin...
