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 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). Materials and Methods Twelve patients aged between 18 and 60 years with surgically acquired partial maxillary defects were included in this study. The patients were given immediate surgical obturators six to ten days after surgery, which were then converted to interim obturators by relining with tissue conditioner. Interim prostheses were used for two to three months until healing and resorption were found satisfactory after which the definitive obturators were fabricated. The SI test described by Plank et al.1 and Wheeler et al.8 was employed in this study. There were significant improvements in the mean SI score from 59.8% without prosthetic obturation, to 89.2% following interim obturation, and 94.7% following definitive obturation (p<0.005). Nine patients (75%) had class I surgical defects, two patients (16.67%) had class II defects, while only one patient (8.33%) had a class VI surgical defect. None of the patients had class III, IV, or class V surgical defects. There was an improvement in the SI score from class I to class VI without obturation, after insertion of interim obturator, and after insertion of the definitive obturator. Conclusion Results support the widely held view that the maxillary obturator is a useful speech rehabilitation aid. It also shows immediate, interim, and definitive obturators are all important in the speech rehabilitation of patients with surgically acquired maxillary defects. Moreover SI is affected by the class of defect. Citation Arigbede AO, Dosumu OO, Shaba OP, Esan TA.

Full textAbstract:
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 maximum coverage of the defect aids in retention, stability, support with improved speech resonance and reduced weight on the unsupported side. This clinical report presents the prosthetic management of a patient having total maxillectomy on left side with definitive hollow bulb closed obturator and cast partial denture on the maxilla.

Abstract Acquired maxillectomy defects produce hypernasal speech, food, and liquid regurgitation into the nasal cavity, impaired deglutition and mastication, and cosmetic deformity. Furthermore, patients with acquired maxillary defects face psychosocial stigma, which has a negative impact on their quality of life. Prosthetic rehabilitation of such defects is required for stomatognathic system restoration and oroantral communication obturation. This case series discusses the fabrication of surgical, interim, and definitive obturator prostheses to restore the acquired dentate maxillectomy defects of three cancer patients. All patients had their treatment in the prosthodontics department of the RUHS College of Dental Sciences. The surgical obturator prosthesis was made before surgery, whereas the interim and definitive obturators were made one month and six months after surgery, respectively. The surgical obturator formed a shield between the surgical pack and the oral cavity. After the surgical obturator and packing were removed, an interim obturator was inserted for three to six months to allow the surgical site to heal. After the surgical site had healed, the fabrication of the definitive obturator began. Prosthetic rehabilitation with obturator prostheses sealed the acquired tissue defects of the palate and restored swallowing, speaking, chewing capacity, and cosmetic value, as well as significantly improved the quality of life of these patients.

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.

Full textAbstract:
Background: Obturator is a prosthesis to replace tissue lost post tumor surgery in the maxilla called maxillectomy. Obturator is made of acrylic and consists of surgery, intermediate, and definitive obturator. Definitive obturator is made using Hollow bulb technique to be light and stable when used. In this case, a definitive obturator was made for a patient using intermediate obturator. Objectives: To inform that obturator can rehabilitate maxillary defect to restore the patient’s mastication, digestive, phonetic, aesthetic and psyche functions. Case report: A 28-year-old man came for postoperative cleft management. Diagnosis is Post OP Hemi maxillectomy Dextra. The procedure begins with impression to obtain study model and the making of individual tray. The next visit is grinding the remaining teeth for occlusal rest placement. Double impression is done to obtain working model and making the bite block. The third visit is bite block try-in on the patient and placed to working model for fixation on the articulator, followed by tooth color determination and laboratory instructions. The fourth visit is wax obturator try-in and checking occlusion, articulation, aesthetics and phonetics. The fifth visit is definitive obturator insertion and follow up. Conclusion: Definitive obturator can rehabilitate defects post maxillary tumor surgery.Keywords: Maxillary defect, definitive obturator, Hollow bulb technique

Background: In the course of research work it was observed that after maxillectomy, prosthetic restoration of the resulting defect is the fundamental step because it signals the beginning of patient’s rehabilitation. Aim: The General objectives of this study is to identify the cases requiring maxillary obturator prosthesis, the types of obturator used in the management of the defects and finally to know the causes of maxillary defect among patients that have attended maxillofacial prosthetic Laboratory, Dental Unit at LUTH from 2013-2023. Methods: In this study, a total number of 75 cases of maxillary defects were seen and the patients’ attendance register was accessed with the help of record officers and all data collected were recorded in a datasheet. Results: The analysis of demographic data pertaining to maxillary cases reveals intriguing patterns regarding gender distribution and religious affiliation. In examining, it becomes evident that within the study period (2013-2023), a total number of 75 maxillary cases were recorded, 35 cases in Females, while Males accounted for 40 cases. This indicates a higher prevalence of maxillary defects among males, Moreover, when considering the yearly prevalence of maxillary cases, it is notable that females consistently exhibited a higher number of maxillary cases compared to males in most years, with the exception of 2019 and 2020. This suggests a potential gender-specific susceptibility to maxillary defects, necessitating subsequent examination into underlying physiological and environmental factors contributing to this disparity. Furthermore, an examination of the types of maxillary defects sheds light on the etiology of these conditions. Congenital defects account for the majority of cases. comprising 54.7% of all cases, followed by traumatic defects at 25.3%, and surgical defects at 20%. Interestingly, while the prevalence of congenital and traumatic defects appears relatively balanced between Males and Females, with slight variations in percentages, surgical defects exhibit a notable difference, with males comprising a higher percentage compared to Females (20% vs. 11%). This suggests potential gender-specific differences in the nature of maxillary defects, particularly those arising from surgical interventions. Moreover, religious affiliation appears to influence the distribution of maxillary cases, as evidenced by the breakdown of cases among Christians and Muslims. It is observed that Christians accounted for a higher number of maxillary cases (42) compared to Muslims (33) over the study period while the rationale for this inconsistency are not explicitly stated in the data, it may reflect to Prachy variations in healthcare-seeking behavior, genetic predispositions, or socio-economic factors between the two religious groups. Regarding the types of maxillary obturators, the data reveals variations in treatment modalities utilized for maxillary defects. Feeding plates dental emerged as the predominant type of obturator, representing 56% of cases, followed by definitive obturators at 40%, and immediate surgical obturators at 4%. This distribution underscores the importance of tailored treatment approaches based on the nature and severity of the maxillary defect, with feeding plates likely employed for infants or individuals requiring early intervention for feeding difficulties. The result of test of hypothesis using Chi- Square statistical tool shows that there is a relationship between maxillary defects and the use of obturator. Conclusion: Timely management of these defects with common type of obturator is useful in the practice. It was recommended that dental training and continuous education should be done to practicing dental Technologists.

Full textAbstract:
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. This case report describes the prosthodontic rehabilitation of a maxillary defect involving the left lateral hard palate and left posterior buccal mucosa with intact ridge over the defect area using a hollow bulb obturator. The lost wax technique used for fabrication of the obturator is an easy, cost-effective technique which is simple to execute from available resources. It provides hollowness to the prosthesis and reduces weight of the prosthesis thereby aiding in retention and stability of the denture.

Projeto de Pós-Graduação/Dissertação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Medicina Dentária<br>Apesar da cavidade oral ser um local de fácil acesso e observação, a realidade é que a incidência do cancro oral no nosso país é cada vez mais elevada. O mais preocupante é, sem dúvida, o tardio diagnóstico deste tipo de patologia que acaba por contribuir para taxas de morbilidade e mortalidade elevadas. Desta forma, o conhecimento da sintomatologia adjacente ao cancro oral, quer por parte dos profissionais de saúde, quer por parte da população em geral, assume uma importância crucial para a minimização das taxas bem como das sequelas a que este tipo de patologia se associa.
O tratamento do cancro oral assume diversas modalidades, entre as quais a cirurgia, a quimioterapia e a radioterapia, todavia é a cirurgia que se assume como tratamento de primeira linha, na maioria dos casos. Desta, resultam defeitos cirúrgicos que, quando acometem a maxila, designam-se por defeitos maxilares e que causam danos estéticos e funcionais que comprometem não só o estado físico do paciente como também o seu estado psicológico e funcional.
A qualidade de vida dos pacientes maxilectomizados é, em muito, minimizada e a cura desta patologia passa não só pela erradicação da doença como também pela reabilitação estética e funcional do paciente permitindo o restabelecimento de funções básicas como a mastigação, deglutição e fonética.
Assim sendo, e numa época em que o cancro oral é, cada vez mais, retratado é primordial que o médico dentista conheça, de forma abrangente, as diversas abordagens e procedimentos existentes que permitem a reabilitação do paciente, desde a cirurgia reconstrutiva, à reabilitação protética e até mesmo à reabilitação com implantes.
Na busca por respostas para questões como “ O que fazer a um paciente após-maxilectomia?” ou “ Quais as opções de reabilitação que posso apresentar?” foi realizada uma revisão bibliográfica, tendo sido encontrados artigos relativos a esta temática publicados entre 1998 e 2014, pesquisados com palavras-chave como: oral cancer; oral rehabilitation; maxillary defects classifications; maxillofacial defects; prosthodontic rehabilition; prosthetic rehabilition in maxillary defects; inflatable hollow obturator; dental implants in maxillectomized patients; zigomatic dental implants; maxillectomy patient; e history of obturators.
Como resultados desta foi possível constatar que a reabilitação oral do paciente maxilectomizado é ainda uma temática controversa nos dias de hoje. Apesar de tal facto, conclui-se que não existe apenas uma opção reabilitadora para estes pacientes, sendo diversas as abordagens que podem ser realizadas pelo que a existência de uma equipa multidisciplinar que integre profissionais de diversas áreas, desde a oncologia, cirurgia oral, prostodontia entre outras, é fundamental.
De uma forma geral, foram abordadas três opções reabilitadoras à disposição destes pacientes sendo elas a cirurgia reconstrutiva com enxertos, a reabilitação protética destes defeitos, abordando-se os tipos de próteses obturadoras existentes; bem como a reabilitação com implantes dentários usando como recurso não só os implantes convencionais como também os implantes zigomáticos. Although the oral cavity is a place of easy access and observation, the reality is that the incidence of oral cancer in our country is increasingly high. The most principal problem is, undoubtedly, late diagnosis of this type of pathology that ultimately contributes to high rates of morbidity and mortality. Thus the knowledge of the symptomatology adjacent to oral cancer, which by health professionals or by general population, is very important for the minimization of rates and injuries that this disease provokes.
The treatment of oral cancer could be surgery, chemotherapy and radiotherapy, however surgery is the first treatment, in the most of cases. When the maxilla is affect, the surgical defects are termed maxillary defects and these cause cosmetic and functional impairment that compromises not only the physical condition of the patient but also their psychological and functional status.
The quality of life of maxillectomy patients are very low and the cure of this disease involves not only the eradication of the disease as well as the aesthetic and functional rehabilitation of the patient allowing the restoration of basic functions such as chewing, swallowing and speech.
This way is essential that dentists know the various approaches and procedures for rehabilitate these patients as like reconstructive surgery, prosthetic rehabilitation and rehabilitation with implants.
In this search, with the objective to answer a questions as like “What can I do in maxillectomized patients?” and “What are the options that I have to rehabilitate these patients?” were made a review with keys-words: oral cancer; oral rehabilitation; maxillary defects classifications; maxillofacial defects; prosthodontic rehabilition; prosthetic rehabilition in maxillary defects; inflatable hollow obturator; dental implants in maxillectomized patients; zigomatic dental implants; maxillectomy patient; e history of obturators. With this review was possible conclude that the oral rehabilitation of these patients is controversial. Despite this fact, the conclusion is that doesn´t exist only one option for these patients so is important have a multidisciplinary team that should integrate an oncologic specialists, oral surgeons, prosthetics and others.
In general, three rehabilitative options are available to these patients wich are reconstructive surgery with grafts, prosthetic rehabilitation (obturator prosthesis) and the rehabilitation with dental implants that can be resorted with conventional implants or zygomatic implants.

Pacientes portadores de comunicação oronasal necessitam de dispositivo protético obturador, para o restabelecimento da sua função, estética e qualidade de vida perdida, devido à remoção ou ausência da maxila. Esta tecnologia reabilitadora vem se desenvolvendo há alguns séculos, com aprimoramentos das técnicas de confecção e materiais odontológicos que auxiliem na elaboração de obturadores cada vez mais eficientes, principalmente no que se refere a sua adaptação. Esta tecnologia é fortemente dependente tanto do domínio das técnicas laboratoriais, quanto de habilidades específicas na arte da reconstrução da face (manuais, sensitivas e tácitas), pois sua confecção é artesanal, personalizada e individualizada, determinando que a disponibilidade e distribuição dos recursos humanos qualificados para a sua elaboração constituam-se em obstáculo significativo para um acesso mais amplo e equânime. O trabalho em tela teve por objetivo examinar o estado da arte relativo às diferentes técnicas de moldagens e confecção das próteses obturadoras utilizadas no cuidado reabilitador de pacientes maxilarectomizados, buscando subsidiar proposições para o seu aprimoramento. Este estudo teórico-exploratório utilizou dois caminhos metodológicos complementares. O primeiro tomou por base uma revisão de literatura científica nacional e internacional e acadêmica, publicada sob a forma de artigos, teses e dissertações, utilizando as bases bibliográficas MEDLINE, BBO, LILACS, SCIELO, Biblioteca Virtual de Saúde e Colaboração Cochrane, e as bases de dissertações e teses da CAPES Banco de Teses; Base Thesis e Biblioteca Digital de Teses e Dissertações (BDTD), do Instituto Brasileiro de Informação em Ciência e Tecnologia (IBICT). O segundo caminho teve por foco a exploração de um dos principais limitadores ao acesso e utilização dos dispositivos obturadores do país a escassez de recursos humanos especializados buscando-se identificar os centros formadores de capacitação nesta área específica, a partir da Coordenação de Aperfeiçoamento de Pessoal Nível Superior (CAPES) do Ministério da Educação e do Conselho Federal de Odontologia, bem como o número de profissionais Protesistas Bucomaxilofaciais e Técnicos em Prótese Dentárias disponíveis em território Nacional para confecção dos obturadores, a partir de consulta ao Conselho Federal de Odontologia (CFO). Os resultados permitiram traçar um panorama histórico de desenvolvimento tecnológico destas próteses desde os primeiros dispositivos utilizando materiais da natureza. São apresentados e discutidos vários tipos de obturadores, bem como as diversas técnicas e materiais envolvidos, sendo também explorados seus benefícios para reabilitação, em particular os impactos na qualidade de vida associados ao seu uso, e alguns obstáculos técnicos a serem ultrapassados para melhoria da tecnologia reabilitadora. O exame do quantitativo e distribuição regional dos diversos profissionais envolvidos na sua confecção sinaliza uma grande escassez destes recursos humanos, bem como sua grande concentração na região Sudeste, em particular no eixo Rio - São Paulo. Além disto, o numero de centros formadores em termos técnicos de nível médio e de pós- graduação é insignificante e ainda vem ocorrendo à desativação de cursos, pela falta de procura. Esses dados apontam para significativas dificuldades no acesso a tecnologia, proveniente, sobretudo da falta e má distribuição regional de profissionais capacitados em prótese bucomaxilofacial em território nacional, dos escassos centros formadores de recursos humanos e do baixo incentivo ao ensino e pesquisa<br>Patients with oral-nasal connection due to the absence or extirpation of the maxilla need a prosthetic obturator for esthetical reasons, to restore function, and to partially regain the lost quality of life. This technology has evolved in the course of many centuries in conjunction with the improvement in manufacturing techniques and odontological materials that play a role in the elaboration and design of more efficient obturators, especially regarding their adaptation. This technology is exceedingly dependent on the mastery of laboratorial methods as well as specific skills in the art of facial reconstruction because its confection is artisanal, personalized, and customized. The existence and distribution of suitable human resources are an evident obstacle to the evenly access to this technology. The aim of this work was to scrutinize the state of the art regarding different moulding and manufacturing techniques of prosthetic obturators employed in the rehabilitation process of maxillectomized patients, intending to make a contribution for its improvement. This theoretical-exploratory study used two complementary methodological instruments. One was a broad review of the national and international scientific literature published as articles, doctoral thesis and dissertations, utilizing different bibliographical databases: MEDLINE, BBO, LILACS, SCIELO, Biblioteca Virtual de Saúde (Virtual Health Library), and The Cochrane Collaboration, as well as the doctoral thesis and dissertations included in the CAPES database - Base Thesis and Digital Library of thesis and dissertations, from the Brazilian Institute of Information in Science and Technology. The other methodological instrument focused on the investigation of the main reasons for the restricted access of patients to prosthetic obturators in our country the lack of expert human resources trying to identify the centers of excellence and development in this specific area using the Coordenação de Aperfeiçoamento de Pessoal de Nivel Superior (CAPES) of the Ministry of Education and of the Federal Council of Odontology, as well as the number of dedicated technicians making bucomaxillofacial prosthesis and dental prosthesis in our national territory by consulting the Federal Council of Odontology. The results allowed the construction of a historical frame of the technological development of these prosthesis from the very first obturators manufactured with natural materials. Different types of obturators are presented and discussed, along with the many techniques and the various materials employed. Their specific benefits for the rehabilitation process are also discussed, in particular the impact in quality of life associated with its specific use. Obstacles to the further development and implementation of the rehabilitation technology are also examined. The availability and regional distribution of qualified personnel reveal a remarkable shortage of human resources and its overwhelming concentration to the Southeast region, particularly the Rio de Janeiro - São Paulo area. There are a negligible number of centers for preparing technicians and offering post graduation opportunities. Furthermore, there are centers being deactivated due to the lack of demand. This data demonstrates the striking difficulties in making this technology more evenly available throughout the national territory as a result of the lack of incentive for education and research

A 37-year-old male patient reported that he had gone to three dentists who were unable to solve the problem, and was then referred to the specialist. Clinically, the patient presented pain on vertical percussion and palpation. Radiographically, the presence of filling material and anatomy suggesting an extra canal was observed. The root canal was unfilled with the Prodesign S rotary system from Easy file #25.08, followed by radiographic odontometry. The foraminal patency was performed with 30#01 files and the root canal was reprepared with rotary instrumentation (Prodesign Logic 2 System: 30#05 file, determining an enlargement and modeling appropriate to the anatomy of the canal. and the obturation of the root canal system was performed using the 30#05 single cone technique, associated with Bio C Sealer cement. It is concluded that variations in the configuration of the root canal are a great challenge for the endodontist during endodontic procedures.

Full textAbstract:
The aim of the present study is to determine the prevalence of periradicular lesions in permanent anterior teeth treated endodontically and in teeth with intraradicular retainers through the analysis of periapical radiographs. A survey of 1000 radiographs of patients treated endodontically in the dental clinics of the Faculty of Dentistry of Pernambuco – FOP/UPE was carried out, constituting a sample of 467 radiographs that fit the established criteria. In the analysis, the following data were collected: canal obturation limit, presence or absence of periapical lesion, homogeneity of the filling material characterized as without failure or with failure when presence of any radiotransparency in the root canal, presence or absence of the space between the intraradicular retainer and filling material and coronary sealing classified as adequate or inadequate. Through the data obtained, the highest frequencies corresponded to maxillary incisor teeth. It indicated that the filling limit characterized as beyond the apical foramen was the one with the highest rate of periapical lesion presence (66.7%), followed by the filling limit characterized as exact (32.4%).
