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 precision attachments. (Eur J Dent 2012;6:212-217)

Abstract:

This study investigates specific articulatory problems and compromised speech intelligibility associated with and without the use of an intraoral prosthesis in 13 surgically treated oropharyngeal cancer patients. Ten patients had tonsil and varying amounts of posterior tongue, tongue base, and soft palate resected. Three other patients had soft palate resected with no involvement of oral tongue or tongue base. Three types of intraoral prostheses were employed. One type was a maxillary reshaping/lowering prosthesis, the second type was a soft palate obturator, and the third type was a combined maxillary reshaping/lowering and soft palate obturator prosthesis. Review of the individual cases in relation to improvements in articulation and conversational understandability revealed mixed success with prosthesis usage in the group of 10 patients with posterior resection. In the group of three patients with soft palate resection, however, two patients benefitted from use of obturators. The results identify the need for some criteria in patient selection for intraoral prosthetic rehabilitation. However, in view of the individuality of each patient case in terms of surgical deficit, patient characteristics, and varied prosthodontic/speech-language pathologist teams, it is impossible to develop prescriptions for prosthodontic construction based on surgical deficit alone.

Abstract:

ABSTRACT Surgical treatment for palate cancers can result in oral-nasal/sinus communication, which impairs the swallowing, speech and chewing ability of patients with reflux of ingested food into the nasal cavity, reducing their quality of life. This article aims to report how three cancer patients, with different types of palate cancer undergoing partial maxillectomy with oroantral or oral-nasal communication as postoperative sequelae were prosthetically rehabilitated from 2009 to 2015. The prostheses were made by dental-surgeons interns in the service of the Multidisciplinary Residency in Oncological Healthcare of the Hospital School of the Federal University of Pelotas (HE/UFPel). One of the patients is completely edentulous, the second partially toothed and in the third case the patient is totally toothed, only requiring the obturator. The creation of prosthetic rehabilitation followed the steps of conventional prostheses, especially observing the particularities in the planning, molding, installation and adjustment stages of the prosthesis. In all cases there was improvement on speech immediately after the prosthesis installation and patients reported greater ease to feed.

Abstract:

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. This case report describes the prosthetic rehabilitation of a maxillectomy patient with a titanium cast hollow obturator using lost wax bolus technique.

Abstract:

Patients using obturator prostheses often present denture-induced stomatitis. In order to detect the presence of oral Candida albicans in patients with oronasal communications and to evaluate the effectiveness of a topical antifungal treatment, cytological smears obtained from the buccal and palatal mucosa of 10 adult patients, and from the nasal acrylic surface of their obturator prostheses were examined. A therapeutic protocol comprising the use of oral nystatin (Mycostatin®) and prosthesis disinfection with sodium hypochlorite was prescribed for all patients. Seven patients were positive for C. albicans in the mucosa, with 1 negative result for the prosthetic surface in this group of patients. Post-treatment evaluation revealed the absence of C. albicans on prosthesis surface and on the oral mucosa of all patients. The severity of the candidal infection was significantly higher in the palatal mucosa than in the buccal mucosa, but similar in the palatal mucosa and prosthesis surface, indicating that the mucosa underlying the prosthesis is more susceptible to infection. The therapeutic protocol was effective in all cases, which emphasizes the need for denture disinfection in order to avoid reinfection of the mucosa.

Abstract:

Maxillofacial defects cause impact on oral health related quality of life (OHRQol) including limitations in functional activities, communication, social interaction, and intimacy. The obturator prosthesis is commonly used as an effective means for rehabilitating maxillectomy patients. The purpose of this study was to investigate impact of definitive obturator prosthesis on oral health related quality of life. In the period between 2015 -2017, a total of twenty five (25) patients with acquired maxillary defects based on Okay classification have been selected and rehabilitated with definitive obturator prostheses .The OHRQol was measured using the Oral Health Impact Profile (OHIP-Edent-19) and Obturator functioning scale (OFS) with standardized questionnaire after 2 weeks & 3months of prosthesis function.To find the significant difference between the bivariate samples in Paired groups the Wilcoxon signed rank test was used. With respect to oral health impact profile –Edent 19 scale, the mean functional limitation score were 6.72 and 5.20 indicates that there is significant improvement in chewing performance after 2 weeks and 3 months of prosthesis function. Significant improvement in oral health impact profile was noticed in physical (M = 5.84, 4.88), Psychological (M=4.84, 3.96) and social disabilities (M=5.28, 4.16). Similarly, when observed with Obturator functioning scale, significant improvement were noted in chewing performance phonetics, appearance and miscellaneous aspects. Analysing the OHIP –Edent-19 scale and obturator functioning scale (OFS-15), statistically significant differences (Wilcoxon rank test p value = 0.0005) were observed. Within the limits of this study, it can be concluded that highly positive correlation exists between definitive obturator prostheses and oral health related quality of life (OHRQol).

Abstract:

ABSTRACT Successful prosthetic reconstruction of hemimaxillectomy defects is a challenging procedure that requires multidisciplinary expertize to achieve acceptable function, speech and esthetics. Rehabilitation of an acquired maxillary defect improves the quality of life for the patient as close to normal as possible. Obturation of the defect depends on its volume and position of remaining hard and soft tissues, to be utilized for retention, stability and support for the prosthesis. The prosthesis should be simple to handle, easy to maintain, biocompatible, light in weight and convenient for future adjustments. This case report describes a clinical case of subtotal maxillectomy, which was successfully rehabilitated with a hollow bulb obturator. How to cite this article Rani G, Gambhir A.

Abstract:

Zygomatic implants have been used for several years for the treatment of extremely resorbed maxilla. Indications were extended for oral rehabilitations after maxillectomy in oncologic patients. A 24-year old patient with a triple A syndrome who underwent a left maxillectomy due to a spinocellular tumour was addressed for prosthetic rehabilitation. As his obturator prosthesis failed, surgical closure of the defect combined with 2 zygomatic implants to support the prosthesis was proposed. Despite a small persistent oro-antral fistula, the new obturator prosthesis restored the patient's functions and esthetics and improved his quality of life. The literature reports less than 40 cases of maxillectomy patients rehabilitated with zygomatic implants (with or without flap closure of the defect). Regardless of implant placement, there is no significant difference between reconstructive surgery and obturator prosthesis. Thus, zygomatic implants seem to be a reliable method for the stabilization of obturator prosthesis, without complex surgical procedure. Nonetheless, reservations should be expressed given the lack of data in terms of long-term follow up.

Abstract:

Background: Maxillofacial prosthetics includes restoration of maxillary defects resulting from resection of palate and nasosinus neoplasms with obturator prostheses which may be colonized by microorganisms and function as a reservoir of infection. Patients with neoplasms commonly also require radiotherapy that can result in changes in saliva quality and quantity and changes in the oral microbial flora. The altered flora, in individuals immunocompromised from cancer therapy, increases their risk of prosthesis-related infections. Objectives: In this review article, we explore microbial biofilms, their main components, mechanisms of microbial adhesion, and stages of biofilm development. We also discuss the different materials that are used for manufacturing maxillary obturators, their characteristic features, and how these can affect microbial adhesion. Furthermore, we shed some light on the factors that affect microbial adhesion to the surface of maxillary obturators including tissue proteins, protein adsorption, and the acquired enamel pellicle. Conclusions: The conclusions drawn from this literature review are that it is imperative to minimize the risk of local and systemic infections in immunocompromised patients with cancer having maxillary defects. It is also important to determine the role of saliva in microbial adhesion to obturator materials as well as develop materials that have a longer life span with surface characteristics that promote less microbial adhesion than current materials.

Abstract:

Patients who undergo surgical resection of the maxillo-mandibular structures as a result of trauma, infection or malignancy, suffer from psycho-social setbacks which has a profound impact on their over-all quality of life. 1,2 These defects, especially those following maxillectomy, result in oroantral communication, facial deformation, impaired speech and difficulty in deglutition. For the rehabilitation of patients with such defects, surgical and prosthetic treatment options are available. As, not all patients can be successfully rehabilitated with reconstructive surgeries due to postoperative complications like graft rejection, the extent of the surgical defect and high psychological impact factor associated with repeated surgeries, prosthetic rehabilitation proves to be an alternative treatment option. The prosthetic rehabilitation of such patients is challenging as it requires restoration of the lost form, function and aesthetics, under constantly changing state of post-surgical intraoral tissues, with limited mouth opening. The maxillofacial prosthesis designed to close congenital or an acquired tissue opening, primarily of the hard palate, is known as an obturator. 3 The obturator has two functional components, one seals the surgical defect and the other replaces the lost dentoalveolarstructures.4-7 The design of an obturator may vary depending on the extent of the defect, remnant dentoalveolar complex, soft tissue undercuts and existent muscle physiology.8,9 Among the two designs, solid and hollow, hollow obturators are widely used. The bulb portion of the hollow obturator, which accommodates the surgical defect, can be open or closed9,10and its selection depends on the prosthodontist’s clinical decision-making skills and the ease of fabrication. In this article we have discussed the rehabilitated patients with single-piece, openhollow bulb definitive obturator. Patients undergo extensive maxillary surgical resections due to aggressive lesions like malignancies and deep fungal infections. Prosthetic rehabilitation of such patients with an obturator becomes of paramount importance as it separates the oropharynx from the nasopharynx, reduces the risk of recurrent infections, replaces lost dentoalveolar structures, permits intelligible speech, reinstates mastication and deglutition, restores facial contour and patient’s self-esteem. The bulb portion of the obturator extends into the defect and accommodates it, forming a hermetic seal. In this clinical report, we highlight the success of prosthetic rehabilitation of maxillectomy patients using single-piece, open-hollow bulb definitive obturator. The meticulous follow-up carried out reveals the success of the prosthesis and adds practice-based evidence to the maxillectomy rehabilitation outcome.

Abstract:

Patients with maxillectomy face problems with speech, swallowing, chewing and appearance. These defects are prosthetically rehabilitated with obturators that prevent oronasal communication, restoring function and social reintegration. An obturator must be light-weight, tight, easy to make and low cost. This article describes a simplified technique for fabrication of an acrylic hollow bulb obturator in two pieces using single flask. The prosthesis is made entirely of heat cure acrylic resin. The two parts of the obturator are sealed with the self-curing resin.

Abstract:

ABSTRACT Preservation of remaining structures is a primary goal of prosthetic rehabilitation. Continuously applied stresses on the remaining tissues from a large, heavy obturator jeopardize the health of the tissues, compromise the function of the prosthesis and affect patient comfort. Various techniques have been described for hollowing the bulb of an obturator after processing to reduce its weight; however, access to the inner aspects of the bulb is limited, preventing adequate control of thickness of the walls. This article presents a case report of a partially edentulous patient after partial hemimaxillectomy successfully rehabilitated with closed hollow bulb obturator prosthesis. The weight of the obturator has always been a hurdle in the rehabilitation of acquired palatal defects. A simple procedure for the fabrication of one piece hollow bulb obturator has been described in this article.

Abstract Aim The purpose of this clinical report is to present a description of the prosthetic rehabilitation of a bilateral complete maxillectomy patient using a two piece magnetically connected prosthesis. Background A complete bilateral maxillectomy defect presents a considerable reconstructive challenge for the prosthodontist. It results in devastating effects on cosmetic, functional, and psychological aspects of the patient. Report A 46-year-old woman reported with a chief complaint of missing teeth in the upper jaw. Her primary concerns were a poor facial appearance, inability to chew food, and regurgitation of the food into the nasal cavity. She was diagnosed with carcinoma of the maxillary sinus, for which a bilateral maxillectomy was done followed by post surgical radiation therapy. The prosthetic treatment objectives were to separate the nasal and oral cavities, restore the mid-facial contour, and improve her masticatory functions by providing a full complement of maxillary teeth using a two-piece connected hollow obturator prosthesis connected by a magnet. Summary Insertion and removal of a large prostheses used for rehabilitation of midfacial defects requires good neuromotor coordination and an adequate mouth opening. Because these factors were problematic for this patient, the treatment plan was to fabricate a two piece magnetically connected prosthesis. After fabrication and insertion of the prosthesis, the fit between two sections was evaluated and instructions for insertion, removal, and maintenance of the obturator were given. The patient's speech, masticatory efficiency, and swallowing dramatically improved after insertion. Citation Chandra TS, Sholapurkar A, Joseph RM, Aparna IN, Pai KM.

Abstract:

Introduction. Facial defects may arise as a result of head and neck trauma or facial tumor ablation. Minor defects can be reconstructed surgically while large defects usually need combined surgical and prosthetic reconstruction. The aim of this study was to present the prosthetic reconstruction of the lateral facial defect using facial colored acrylic prosthesis. Case Report. A male patient with a maxillary defect on the left side and a large lateral facial defect on the same side received an obturator prosthesis as well as a facial colored acrylic prosthesis (facial-orbit) retained by the glasses frame. Satisfied aesthetics was accomplished. However, the stability of the prostheses during mandibular movements could not be achieved which resulted in saliva leakage over the lips. Conclusion. Better functional and aesthetic outcome could be achieved by combined surgical and prosthetic treatment of such large facial defect.

Abstract:

Relevance. Staged orthopedic treatment was used to improve the quality of life of patients who underwent radical maxillofacial surgeries for cancer.Patients and methods. 197 patients receiving treatment for maxillofacial cancer were observed at the Department of head and neck tumors, National Medical Research Centre for Oncology of the Ministry of Health of Russia, in 1998- 2018. All patients underwent radical surgical treatment resulting in postoperative defects of the upper jaw, soft tissues of the zygomatic- buccal-orbital region, nose, or auricle.Results. Removable obturator prostheses with various supporting and retaining elements were made for 159 (80.7 %) patients. Individual facial prostheses were made for 38 (19.3 %) patients: 17 (44.7 %) – external orbital prostheses, 14 (36.8 %) – external nasal prostheses, 6 (15.8 %) – external zygomatic- buccal-orbital prostheses, 1 (2.7 %) – external auricle prosthesis. Combined prostheses were made for 4 patients– removable upper jaw obturator and nose prosthe[1]sis; removable upper jaw obturator and eye prosthesis. Combined prostheses were fixed to each other using magnets. The results of maxillofacial prosthetics were evaluated according to the aesthetic requirements of the patients and their quality of life. Maxillofacial prostheses allowed a complete restoration of chewing, swallowing, and speaking, restored facial deformation, and improved the appearance of patients.Conclusions. Timely and comprehensive orthopedic treatment of patients with postoperative maxillofacial defects after radical surgeries for malignant tumors takes the main place in the complex of rehabilitation measures. Early elimination of extensive defects is aimed at maximum restoration of oral dysfunctions and appearance preservation. The apparent advantages of maxillofacial prostheses involve improvement of social adaptation and the quality of life of patients, which promotes complete rehabilitation and a return to socially useful activities.

Abstract Aim The aim of this report is to describe a quick and simple method of positioning retention magnets when deformed patients are rehabilitated with an oculopalpebral prostheses attached to a maxillary denture/obturator. Background In patients with deformities requiring complex rehabilitations, the use of magnets is the most efficient means of providing combined prostheses with retention quality and stability. Usually prostheses with magnets are in sections and have a magnet in each section. When the sections are put together properly, the magnets are attracted to each other and retain the sections. Report An edentulous patient presented for a post-surgical evaluation of a maxillofacial prosthesis used to repair a partial maxillectomy and left orbital exoneration which removed all adjacent tissues leaving an open communication between the oral, nasal, and orbital cavities. The proposed treatment plan included construction of a maxillary complete denture with a palatal obturator and a mandibular complete denture. Magnets were used to attach the oculopalpebral prosthesis to the maxillary denture/obturator. Summary Use of retention magnets simplify the clinical and laboratorial phase, retains the denture, and makes it stable and comfortable for the patient. This treatment is one successful approach to the restoration of oral function and increases the patient's quality of life. Citation Goiato MC, Fernandes AÚR, dos Santos DM, Barão VAR.

Abstract:

AbstractRehabilitation of hemimaxillectomy patients is a very challenging process. The augmented weight of the prosthesis when closing large defects is often a concern to its retention and lightweight obturators are thus warranted in such clinical situations. Most of the techniques in literature to hollow a prosthesis were designed to make only the defect region of obturator hollow and has limited application when it comes to prosthesis with excessive vertical height. This technique described in this article can be used to hollow vertical height of any prosthesis and successfully replace conventional techniques when they are not feasible.

Abstract:

This study investigated the effect of intraoral-prostheses on swallowing function in 13 postsurgical oral and oropharyngeal cancer patients. Three subjects had resections of the soft palate with no involvement of the tongue. Ten subjects had resections of the posterior oral cavity or oropharynx including resection of the oral tongue, tongue base, soft palate, tonsil, and/or mandible. Patients received either an obturator only, a maxillary reshaping/lowering prosthesis, or an obturator combined with a maxillary reshaping/lowering prosthesis. Swallowing was examined with and without the prosthesis 3 months posthealing using videofluoroscopy; results are presented in the form of case reports. The majority of patients had either unchanged swallowing function or mixed results (i.e., improvement for some but not all bolus consistencies) when using an intraoral prosthesis. The extent of surgical resection, type of reconstruction, and postoperative radiotherapy had an impact on the type of prosthesis constructed and the patient’s ultimate swallowing ability. Despite the swallowing dysfunction demonstrated by some of the patients, all were able to maintain oral intake either with or without the prosthesis in place.

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

Abstract:

ABSTRACT The esthetic and functional rehabilitation of the patients with palatal defects using obturator poses challenge to the clinician. The use of existing teeth along with implants helps in providing good retention, support, and stability to the prosthesis. Ball-socket type of attachments offer efficient, yet economical alternative to these patients. This case report describes management of a hemimaxillectomy adult patient with a class II palatal defect using tooth implant-supported obturator. Osseointegrated implants and direct overdenture post with ball-socket type of attachments were used to construct a definitive obturator for prosthetic rehabilitation of this patient.

Abstract:

A surgical obturator prosthesis is commonly used as an effective means for rehabilitating patient with hemi-maxillectomy defect. The obturator supports the soft tissues after surgery and minimizes the contraction of scar and disfigurement thereby making a positive effect on patient’s overall function and psychology. The goal of prosthodontics to restore missing orofacial structures for improving facial esthetics and oral function for such patients. The inability to achieve adequate retention, stability, support and comfort due to the friability of healing tissues are the common problems associated with prosthetic treatment in the initial phase of treatment. This case report demonstrates a simple technique to overcome such difficulties by the use of soft lining materials in the delayed surgical obturator.

Abstract:

The objective of this research is to evaluate the biomechanical effect of zygomatic implant-supported obturator prostheses in unilateral maxillary defect. Based on CT data, four 3D numerical models were built. One model was a normal craniofacial complex (model 1) and other three models were structures with unilateral maxilla defect reconstructed using clasp-retained obturator prosthesis (model 2), one zygomatic implant-supported and clasp-retained prosthesis (model 3), two zygomatic implant-supported and clasp-retained prosthesis (model 4). Bilateral vertical loads of 300[Formula: see text]N were imposed and the stress and displacement distribution were calculated, analyzed and compared. The bilateral occlusal forces dispersed along the three-mechanical-pillar of the maxillofacial region and the displacement distributed symmetrically in model 1. Because of mechanical pillars break on the affected side, all occlusal forces were transferred by clasps and abutment teeth in model 2, which induced the increase in stress and displacement level. The zygomatic implant restored mechanical pillars and greatly reduced the stress and displacements levels in models 3 and 4. The stress and displacement distributions on clasps, bones, teeth and periodontal ligaments were more reasonable with the support of zygomatic implants. Therefore, the zygomatic implant-supported and clasp-retained prostheses were found to be more effective for unilateral maxillary defect reestablishment.

Abstract:

ABSTRACTThis report describes a different approach for diminishing the movements of orbital prosthesis during mimic movements and chewing function. Mechanical devices such as magnets are used to enhance the retention in case lack of the implants. However rigid fixation of obturator and orbital prosthesis can result in movements of the orbital prosthesis during mastication. In this case obturator and orbital prosthesis are combined by magnets. However this combination is not rigid because of an active part which provides movement. This active part allows movements in a space constructed in the acrylic base of orbital prosthesis. Thus, the movements that may occur on orbital prosthesis during chewing can be diminished by this simple mechanism. Due to the fact that designing such a mechanism that minimizes the movements of the orbital prosthesis contributes patient’s comfort. (Eur J Dent 2011;5:459-464)

Abstract:

Background and aim:Mid-facial defect is one of the most disfiguring and impairing defects. A design of prosthesis that is aesthetic and stable can be precious to a patient who has lost part of his face due to surgical excision. Prosthesis can restore the patients’ self-esteem and confidence, which affects the patients and their life style. The aim of this case report is to describe a technique of mid-facial silicone prosthesis fabrication.Technique:To provide an aesthetic and stable facial prosthesis, the extra-oral prosthesis was fabricated using silicone material, while the intra-oral defect was restored with obturator prosthesis, and then both prostheses were connected and attached to each other using magnets.Discussion:This clinical report describes the rehabilitation of a large mid-facial defect with a two-piece prosthesis. The silicone facial prosthesis was made hollow and lighter by using an acrylic framework. Two acrylic channels were included within the facial prosthesis to provide the patient with clean and patent airways.Clinical relevanceA sectional mid-facial prosthesis was made and retained in place by using magnets, which resulted in a significant improvement in the aesthetical and functional outcome without the need for plastic surgery. Silicone prostheses are reliable alternatives to surgery and should be considered in selected cases.

Abstract:

Maxillary defects occur due to surgical treatment of benign and malignant tumors, congenital malformation, and trauma. Prosthetic rehabilitation in such patients is influenced by the size and location of the defect. The most common of all intraoral defects are seen in the maxilla, in the form of an opening into the maxillary sinus and nasopharynx. These defects create disabilities in speech, deglutition, and mastication. The prosthesis which closes such an opening and recreates the functional separation of the oral cavity and sinus and nasal cavities is referred to as an obturator. Numerous techniques of hollow bulb fabrication have been mentioned in the literature from time to time. But there are only a few methods for bulb fabrication in two-piece obturator. This technique describes a direct investment method of waxed-up closed hollow bulb two-piece obturator.

Abstract:

Prosthetic rehabilitation of atrophic maxilla and large maxillary defects can be done successfully by zygomaticimplant-supportedprosthesis. Zygomatic implants are anavant-gardeto complex andinvasive-freevascularised osteocutaneous flaps, distraction osteogenesis, and the solution to flap failures. A treated case of tuberculous osteomyelitis, with a class II (Aramany’s classification) maxillary defect, reported to oral maxillofacial department, Government Dental College (RUHS-CODS).The defect in this group was unilateral, retaining the anterior teeth. The patient was previously rehabilitated with a removable maxillary obturator. Inadequate retention affected essential functions like speaking, mastication, swallowing, esthetics, and so on due to lack of sufficient supporting tissues. A fixed prosthetic rehabilitation of posterior maxillary defect was done with obturator supported with twosingle-piecezygomatic implants. At 1-yearfollow-up,the patient was comfortable with the prosthesis, and no further complaints were recorded.
