Palatal obturator prosthesis: a clinical case report
Cumhuriyet Dental Journal, 2018
This clinical report describes the details of a prosthodontic rehabilitation of an elderly patient who was diagnosed with mucoepidermoid carcinoma. The palatal defect has caused problems in phonetics and mastication. A previous obturator was made using conventional Polymethyl methacrylate (PMMA). This obturator has caused some discomfort due to food impaction and irritation of the fitting surface over the tissue defect areas. This had resulted in frequent erythema of the areas. Therefore, a new palatal obturator was made still using PMMA but with an addition of an indirect soft acrylic resin over the defect areas. The soft acrylic resin serves to reduce painful irritation of the obturator over the soft tissues around the defect areas. The review appointments up to 6 months revealed satisfactory results with no deterioration in the prosthesis. However, upon the followup appointment at 9 months, we could see some black stains on the fitting surface where the indirect soft acrylic resin was placed. Swabs were taken from the black area on the obturator and the related mucosa intraorally. The swabs were sent for a culture and sensitivity test to find microorganisms that caused the staining. The result confirmed that there were no microorganisms at both areas. This condition suggested that stain could occur on the surface of soft acrylic resin despite good oral hygiene practised by the patient. Further reviews will be made to monitor the condition.
Rehabilitation of Surgically Resected Soft Palate with Interim Velopharyngeal Obturator
Rehabilitation of surgical resection defects is always a challenging clinical scenario. These defects pose a major physiological and psychological threat not only to the patients, but to the entire family. A multidisciplinary team approach, thorough investigation, long term follow up, proper counselling and sympathetic attitude may help to bring these suffering patients back to normal life stream. Recent advancements in Dental Materials, CAD CAM, Laser Technology and Ossseo integrated Implants have revolutionized the treatment outcomes. However in certain clinical case scenarios, conventional prosthodontic principles and routinely available materials are still the gold standards. This case report presents the prosthodontic rehabilitation of soft palate after surgical resection due to adenoid cystic cell carcinoma.

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.
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.
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.
Hollow Bulb Obturator Prosthesis Following Palatal Resection: A Case Report
Global Journal of Oral Science, 2016
Prosthetic intervention with maxillary Obturator prosthesis is necessary to restore the contours of resected palate and to recreate the functional separation of the oral cavity and sinus and nasal cavity. This clinical report describes a technique for fabricating two-stage one piece hollow obturator prosthesis; denture with metal framework and obturator part with heat cured acrylic restoring functions of mastication, speech and esthetic for a patient who had undergone partial maxillectomy for treatment of squamous cell carcinoma.
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.
