Abstract:

ABSTRACTThe majority of maxillary defects can be rehabilitated with conventional simple obturator prosthesis. However, inadequate retention, stability and support may be associated with the use of an obturator. Precision attachments have been used to retain obturators for some time. The use of precision attachments in a dentate maxillectomy patient can yield significant functional improvement while maintaining the obturator’s aesthetic advantages. This clinical report describes the prosthetic rehabilitation of two maxillary defects with an obturator retained using extracoronal resilient precis

Abstract:

Abstract Aim Maxillectomy often results in a high level of morbidity with significant psychological and functional implications for the patient. Such disabilities include inability to masticate, deglutition, and speech disturbance. Unfortunately, little is known about the nature of the speech disturbance and the influence of the class of surgical defects in this group of patients. The aims of the present study were to assess the effectiveness of the maxillary obturator as a speech rehabilitation aid and to examine the influence of the classes of surgical defects on speech intelligibility (SI).

This patient-centered approach describes the prosthetic rehabilitation of a 66-year-old male diagnosed with maxillary osteomyelitis, treated using a heat-cured soft acrylic resin obturator. Following bilateral sequestrectomy of the maxillary molar region, a perforation to the left maxillary sinus was identified. The patient was referred to the maxillofacial prosthetics clinic at Institute of Science Tokyo for rehabilitation. Treatment commenced with the placement of an immediate surgical obturator, followed by a definitive obturator fabricated conventionally with heat-cured soft acrylic resin

Abstract:

Total maxillectomy is the complete resection of one of the two maxillae or resection to the midline. Surgical intervention creates communication between the oral cavity, nasal cavity and maxillary sinus. Postsurgical maxillary defects predispose the patient to hypernasal speech, leakage of food bolus and liquids into the nasal cavity, impaired mastication and various degrees of cosmetic deformities. Prosthodontic rehabilitation with obturator prosthesis restores the missing structures and acts as a barrier between the communications among the various cavities. Hollow bulb obturator with the ma

Maxillary intraoral defects due to surgical resection create an open link between the oral and nasal cavities causing difficulty in deglutition, speech, and an unaesthetic appearance . Maxillary obturator prosthesis is a more frequent treatment modality than surgical reconstruction for maxillectomy in patients suffering from oral cancer. The obturators often become heavy and hence are hollowed out in the defect portion to reduce its weight as a standard practice.

Abstract:

Acquired defects in the maxilla lead to oro-antral communication with the nasopharyngeal complex. In recent times, post-Covid necrosis of maxilla due to mucormycosis leads to rapid invasion of surrounding tissues resulting in a maxillofacial defect. The surgically resected maxilla can have a devastating impact on the lifestyle, esthetics, speech and function of the patient. Obturators provide a hollow extension into the defect that seals the oro-antral defect and stops any communication between oral cavity and nasal complex.

After surgical excision of tumors involving the maxilla, depending on their location and size, maxillary defects can have harmful consequences, both esthetic and functional. These effects disrupt all the functions of the manducatory system, namely breathing, swallowing, and especially phonation, thus affecting negatively the patient’s psychological state. Despite the evolution of reconstructive surgical techniques and the development of microsurgery, conventional obturator prostheses are still relevant. In fact, these prostheses restore the main functions of chewing, phonation, and swallowing.

Obturators are vital for restoring function and appearance in patients with maxillofacial defects, though traditional fabrication involves multiple clinical visits and extended production time. This technique report details a digital approach using computer-aided design/manufacturing (CAD/CAM) and 3D printing to duplicate an obturator for a 74-year-old patient with maxillary bone necrosis. By using a chairside intraoral scanner, we obtained a digital model of the existing obturator, avoiding traditional impression-taking and reducing procedural discomfort. A 3D-printed obturator was fabricated

Abstract:

Maxillary resection of tumors can result in significant functional and aesthetic challenges for patients. This case report describes successful rehabilitation of a patient who underwent partial maxillary resection following tumor removal. A custom-made hollow-bulb obturator was used to restore the oral function and facial aesthetics. This report outlines the treatment process, prosthetic design, clinical and prosthetic aspects of the interim obturator, prosthesis fabrication and patient adaptation.

Based on literature data, this article reviews a range of problems associated with hygienic care after obturation prostheses and the oral cavity after combined treatment of malignant neoplasms. At the present time, replacing prosthetic care after maxillary resection due to malignant neoplasms using obturator prostheses is the main method for rehabilitation of oncological patients. Such methods as dental prosthetic care based on dental implants and removable dentures for elimination of partial and complete edentulism is impossible in such conditions.

Abstract:

Inverted papilloma arising from the sinonasal mucosa often necessitates a total or partial maxillectomy, creating a significant palatal and alveolar ridge defect. These defects can lead to sequelae like nasal regurgitation, compromised oral and nasal competence, impaired mastication, and deglutition due to lack of bony support, and altered speech due to changes in oral cavity anatomy. Facial aesthetics can also be negatively impacted with the potential for a sunken malar eminence or collapsed midface. While prosthodontic rehabilitation with obturators aims to restore function and aesthetics, c

Abstract:

Maxillary defects can be congenital or acquired in nature. Anatomical defects may be created between oral and the nasal cavity due to surgical resection and patients are usually faced with difficulties while performing normal functions such as speaking and swallowing, due to the communication formed between the cavities. Rehabilitation of the defect site with an obturator prosthesis assists in achieving these goals reducing the morbidity and thereby improving the psychological state of the patient. While rehabilitating these large defects, one of the main problems is with the weight of the pro

Abstract:

Tumors involving the hard palate, maxillary sinus, or nasal cavity require maxillectomy based on the extent of the lesion. Lack of these boundaries affects the speech, esthetics, and masticatory function. Prosthetic rehabilitation of these defects can be done utilizing zygomatic implants. This present case describes the use of a zygomatic implant to retain a maxillary obturator in a 22-year-old male patient following partial maxillectomy (Brown’s Class 2b) due to odontogenic myxoma. A surgical obturator was secured in position subsequent to the implant placement. Following the healing period,

The prosthetic rehabilitation of a patient with maxillary defect is a very challenging task. Obtaining proper retention when almost half the dentition along with the supporting bone is missing is difficult to obtain. Proper knowledge of the anatomy of both the structures lost in resection as well as the remaining portion helps in fabrication of an effective prosthesis. This article describes the management of acquired maxillary defect case with semi precision attachments enhancing the retention of the obturator prosthesis.

Patients with palatal insufficiency, speech and deglutition becomes impaired, thereby requiring prosthodontic rehabilitation. The prosthodontic rehabilitation of patients with acquired defects of the maxilla after surgical resection is the complete responsibility of a maxillofacial prosthodontist. He has to recreate an artificial barrier between the cavities and thus restore the functional capabilities of speech, mastication and swallowing. Palatal obturator is the only substitute which cov
