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.
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.
Goal of prosthodontics is rehabilitation of missing oral and extra oral structures with restoration of normal function of mastication, speech, swallowing, appearance etc. Malignancies are common in oral region, which are treated through surgical intervention. Surgical intervention creates anatomic defect which forms communication among the oral cavity, nasal cavity and maxillary sinus. In such cases it is very difficult for the patient to perform various normal functions like mastication, swallowing, and speaking etc. Prosthodontic rehabilitation with obturator prosthesis restores the missing structures and act as a barrier between the communications among the various cavities.

It is a considerable challenge for a prosthodontist to rehabilitate and sustain the prosthesis in edentulous patients with bilateral maxillectomy. Compelling evidence is lacking with respect to the treatment outcome when the maxillary defects are closed surgically in comparison to their prosthetic rehabilitation. Four edentulous male patients, with bilateral maxillectomy defects were referred for prosthodontic intervention to meet their nutritional and speech issues. In the absence of intra oral supporting and retentive structures, it was decided to retain the obturator utilizing extraoral aid to address their functional needs. Customized headgear face-bow retained obturators were adequately retentive and did serve its purpose well in all four patients. It also gave the liberty to alter retention and refine the prosthesis at will, provided access to the operated site for a quick evaluation of disease recurrence, and was economical to the patients. Considering the encouraging outcome experienced in this special category of individuals, it would be reasonable to believe that the headgear face-bow assembly has an immense potential to function as a valuable, prudent, and a viable retentive aid for a non-implant retained obturator in edentulous patients with extensive maxillary defect.

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.

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...

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.
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.
