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.

INTRODUCTION Maxillary defects are created by surgical treatment of benign or malignant neoplasms, as well as congenital malformation and trauma and their occurrence is also associated with the enucleation of maxillary cysts (1). Squamous cell carcinomas account for two thirds of the malignant neoplasms of the upper gingiva and hard palate. Lesions in these areas account for 1-5% of total occurrence in the oral cavity. 1 Adjacent structures are vulnerable to metastasis during the confirmation of the diagnosis. With this eventuality, the recommended treatment for these types of lesions is alveolectomy, palatectomy, partial or total maxillectomy. These treatment outcomes depend on the location and aggressiveness of the actual lesion, its histiotype, patient’s age and general health status (1). Patients with acquired maxillary defects differ from those with congenital defects due to the abrupt alteration in physiologic processes associated with surgical resection of the maxillae (1). T...
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.

Tissue integrated oral implants have initiated a new perspective in oral rehabilitation of tumor patients who have had undergone surgical resection procedure. The present case demonstrated a simple and predictable approach to rehabilitate a patient who had partial maxillectomy using dental implants. The use of an implant in conjunction with hollow bulb obturator shared remarkable improvement in retention and stability of the existing complete denture prosthesis.

Aim: To prosthetically rehabilitate maxillary defect in a patient with near total maxillectomy using hollow bulb obturator.Case description: Authors report a case of 64-year-old male patient with near total maxillectomy with respect to the left side who was referred for the prosthetic rehabilitation.Conclusions: The hollow bulb definitive obturator prosthesis rehabilitated the patient in terms of masticatory function, phonetics and esthetics. The hollow bulb design ensured patient comfort due to its decreased weight.
Prosthetic rehabilitation of patient with maxillofacial defect by hollow bulb obturator

Introduction: Post-surgical maxillary defect is mostly repaired by the use of an obturator, which is often quite heavy due to the extension into the defect that is better relieved by making it hollow. Objective: To fabricate hollow bulb obturator in simple way. Case: An 85 year old man was referred from ENT department after hemimaxillectomy to remove squamous cell carcinoma, for obturator prosthesis and was treated with hollow bulb obturator prosthesis. Conclusion: The hollow bulb reduces the weight of prosthesis making is comfortable for the patient. DOI: http://dx.doi.org/10.3126/hren.v11i3.9656 Health Renaissance 2013;11(3):284-286

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.

Background: There is insufficient evidence for the efficacy of silicone soft reliner on the obturator prosthesis after maxillectomy for oral malignant tumors. Objective: To verify the efficacy of silicone soft reliner on the obturator prosthesis after maxillectomy, by evaluating masticatory performance and quality of life (QoL). Methods: This was a single-arm prospective interventional study, verifying the efficacy of silicone soft reliner (GC RELINE II ®) on the maxillary obturator prosthesis. Data were obtained from a comparison of the endpoints after 14 days of continuous use of acrylic and silicone soft-lined prostheses. The primary endpoint was masticatory performance. The secondary endpoints were occlusal performance and oral health-related QoL (OHRQoL). The masticatory performance, occlusal performance, and OHRQoL were assessed by glucose concentration, maximum bite force, and the Japanese version of Oral Health Impact Profile (OHIP-J49), respectively. Results: This study included five patients (two males, three females), aged between 71 and 88 years, with a median of 74 years. The median of glucose concentration indicated a statistically significant improvement between the acrylic resin (99.6 mg/dL) and silicone soft reliner (126.0 mg/dL) obturator prosthesis (p = .043). There was no significant difference in the median of maximum bite force between the acrylic resin (302.0 N) and silicone soft reliner (250.0 N) obturator prosthesis (p = .893). Functional limitations domain of the OHIP-J49 indicated a statistically significant improvement between the acrylic resin and silicone soft reliner obturator prosthesis (p = .043).

Material and Method. The procedure we used was fi rst applied in the Oral and Maxillofacial Surgery Clinic in Cluj-Napoca seven years ago on patients suffering from tongue and/or oral fl oor malignancies in order to reconstruct these anatomical areas after the excision of the tumours in oncological safe limits. Most of its preparation procedure was made according to the classical method with some modifi cations in the preparation of its base. In order to enhance its covering area and functional availability and to eliminate some drawbacks, the route to the receptor area was changed. The submandibular course was used instead of the transbuccal one. Results. In all 21 patients who underwent surgery, a considerable enhancement of fl ap covering availability was obtained. It was able to cover defects ranging from the posterior limits of the tongue and oral fl oor to the tongue tip even beyond the midline. Unlike in the classical method there was no need to perform tooth extractions in dentulous patients. It is a one step procedure. Thus, the second step of the classical method was eliminated. Conclusions. The naso-labial fl ap with submandibular course offers covering and functional availability superior than the classical one with transbuccal route. It preserves and reconstructs the perimandibular anatomical sites. It also shortens the surgical treatment period of tongue and oral fl oor malignancies.
