Obturator Prosthesis for Edentulous Hemi-Maxillectomy patients: A Case Study
International Journal of Advances in Scientific Research and Engineering (ijasre), 2020
The maxillary tumors include various histological entities which are the subject of a very particular treatment. Clinical, radiological and anatomopathological criteria are used to determine the diagnosis. In spite of the evolution of reconstructive surgical techniques and the development of microsurgery, the conventional obturator prosthesis is still in use nowadays. In this context, it must restore the main functions of chewing, phonation and deglutition and give the patient a satisfactory aesthetic appearance.
A Novel Technique for Fabrication of Hollow Obturator for a Maxillary Defect: A Case Report
Journal of Nepalese Prosthodontic Society, 2022
Prosthodontic rehabilitation following aggressive infections and malignancies is challenging. Surgical intervention may lead to anatomical defects resulting in oro-antral communication that causes difficulty in mastication, deglutition, impaired speech and facial disfigurement. The role of a Prosthodontist in maxillary defects is to restore these defects with the fabrication of obturators. However, the extent of the obturator into these large defects necessitate bulkier, heavy prosthesis which would likely be nonretentive and uncomfortable for the patient. Hollow bulb obturators are fabricated to reduce the weight of these prostheses. The method of fabrication of hollow bulb obturators with lost salt technique in the maxillary defect is described in this case report.
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.
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.
A Simple Method of Fabricating an Interim Obturator for a Maxillectomy Defect: A Case Report
, 2023
The objective of interim obturator placement is to restore and maintain oral function to a reasonable level during the postoperative period. A 65 years old female patient of Aramany Class I maxillary defect was prosthetically rehabilitated by an Interim obturator. The patient was undergone a partial maxillectomy due to removal of sino-nasal carcinoma in the right side of the hard palate. Reasonable amount of retention, stability and support were found on subsequent recalls. Slight margin gap and lack of peripheral seal at the defect side was noted. The interim obturator restores mastication, swallowing, articulation and intelligibility of speech and the contour of the mid face. Rehabilitation with interim obturator prosthesis was functional, reliable, and has a low level of invasiveness. Interim obturator makes a prosthodontist way easy, to fabricate definitive obturator for the maxillary defect patient.
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.

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.
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.
