ABSTRACT
The objective of this study was to analyze the influence of insertion torque, bone type, and peri-implant bone loss on implant stability quotient (ISQ) of cylindrical external hexagon (EH) and Morse Taper (MT) implants. Forty-four single implants were placed in the edentulous areas of 20 patients who met the inclusion and exclusion criteria. Immediately after implant placement (t1) and after osseointegration (four and six months for mandible and maxilla, respectively) (t2), insertion torque, resonance frequency, and peri-implant bone loss were measured using probing depths and digital periapical radiography. A significant difference was noted in the ISQ values between t1 and t2 in type III bone for EH and MT implants. No significant difference in bone loss values was observed when comparing bone types for EH or MT in all evaluated sites. Based on marginal bone loss assessed using radiography, there was no significant difference between the MT and EH groups. A positive correlation between torque and ISQ t1 value was observed for MT (correlation: 0.439; p = 0.041) and EH (correlation: 0.461; p = 0.031) implants. For EH and MT implants, the greater the insertion torque, the greater was the ISQ value (moderately positive correlation). A weak negative correlation was found between bone type and ISQ t1 for MT implants. Contrarily, no correlation was observed between bone type and ISQ t1 for EH implants. In all cases, bone loss around the implants was clinically normal.

In this study, we aimed to evaluate the halitosis and pain threshold of the peri-implant soft tissues in individuals rehabilitated with implant-supported prostheses. Forty-eight subjects were divided into four groups (n = 12) according to their prosthetic rehabilitation: single-tooth fixed prosthesis, multi-tooth fixed prosthesis, overdentures, and the Brånemark protocol. Halitosis was measured using a halimeter, whereas the pain threshold was measured using Von Frey monofilaments. Measurements were taken before (t0) and 30 days after (t1) placement of healing caps, and at the time of (t2) and 30 days after (t3) prosthetic placement. Halitosis data were analyzed using the chi-square test and Bonferroni correction (p < 0.05). Two-way ANOVA and Tukey's test (p < 0.05) were used to analyze pain threshold data. We noted an association between halitosis and time for the Brånemark protocol [X2(6) = 18.471; p = 0.005] and overdenture groups [X2(6) = 17.732; p = 0.007], and between halitosis and type of prosthesis only at t0 [X2(6) = 12.894; p = 0.045]. The interaction between time and the type of prosthesis significantly interfered with the mean pain threshold values (p = 0.001). At most time points, the majority of participants in each group had clinically unacceptable halitosis. After 30 days of using the prostheses, the overdenture group had a lower pain threshold compared to the Brånemark protocol group.

Introdução: O tratamento de tumores malignos ou benignos, podem resultar em procedimentos cirúrgicos, como a maxilectomia parcial ou total, gerando comunicação bucosinusal nos pacientes. Uma forma de resolver estas alterações maxilofaciais é através do tratamento reabilitador com próteses obturadoras a fim de restabelecer a função mastigatória, estética, fonética e psicológica. Objetivo: o objetivo deste trabalho foi relatar o caso clínico de um paciente oncológico que foi reabilitado com prótese obturadora devido à maxilectomia por neoplasia maligna de seio maxilar. Relato de caso: Paciente de 62 anos, sexo masculino, procurou atendimento odontológico no Centro de Oncologia Bucal da Universidade Estadual Paulista "Júlio de Mesquita Filho" (UNESP) de Araçatuba SP após a realização de uma maxilectomia parcial com comunicação bucosinusal e foi encaminhado para o Curso de Especialização em Prótese Dentária da Faculdade de Odontologia Unesp/Araçatuba-SP para a reabilitação. Foi proposto, primeiramente a realização da prótese obturadora para fechar a comunicação bucosinusal e uma prótese total inferior para o arco antagonista e, posteriormente, a realização de uma prótese facial. Conclusão: O tratamento reabilitador com próteses obturadoras possui um bom resultado estético e funcional, favorecendo uma melhor função mastigatória e fonética, e melhorando consideravelmente a condição psicológica que é muito afetada nos pacientes submetidos a maxilectomia total ou parcial, sendo necessário uma boa interação com toda a equipe multiprofissional envolvida para que haja um melhor tratamento integrado para a reabilitação e melhora da qualidade de vida(AU)
Introduction: The treatment of malignant or benign tumors can result in surgical procedures, such as partial or total maxillectomy, generating oral communication in patients. One way to resolve these maxillofacial changes is through rehabilitative treatment with obturator prostheses in order to reestablish masticatory, aesthetic, phonetic and psychological function. Objective: the objective of this work was to report the clinical case of a cancer patient who was rehabilitated with an obturator prosthesis due to maxillectomy for malignant neoplasia of the maxillary sinus. Case report: A 62-year-old male patient sought dental care at the Oral Oncology Center of the Universidade Estadual Paulista "Júlio de Mesquita Filho" (UNESP) in Araçatuba SP after undergoing a partial maxillectomy with oral cavity and was referred for the Specialization Course in Dental Prosthesis at the Faculty of Dentistry Unesp/Araçatuba-SP for rehabilitation. It was proposed, firstly, to create an obturator prosthesis to close the bucosinusal communication and a total lower prosthesis for the antagonistic arch and, later, to create a facial prosthesis. Conclusion: Rehabilitative treatment with obturator prostheses has a good aesthetic and functional result, favoring better chewing and phonetic function, and considerably improving the psychological condition that is greatly affected in patients undergoing total or partial maxillectomy, requiring good interaction with the entire the multidisciplinary team involved so that there is better integrated treatment for rehabilitation and improved quality of life

Resumo Este estudo teve como objetivo avaliar a halitose e o limiar de dor dos tecidos moles peri-implantares em indivíduos reabilitados com próteses implantossuportadas. Um total de 48 indivíduos foram divididos em quatro grupos (n=12), de acordo com as reabilitações: prótese fixa unitária, prótese fixa multidentária, sobredentadura e protocolo de Brånemark. A halitose foi medida com um halímetro, enquanto o limiar de dor foi medido com monofilamentos de von Frey. As medições foram feitas antes (t0) e 30 dias após (t1) a colocação das tampas de cicatrização e no momento (t2) e 30 dias após (t3) a colocação da prótese. Os dados de halitose foram analisados por meio do teste qui-quadrado e correção de Bonferroni (p < 0,05). ANOVA de duas vias e o teste de Tukey (p < 0,05) foram usados para analisar os dados do limiar de dor. Observou-se associação entre halitose e tempo para o protocolo de Brånemark [X2(6) = 18,471; p = 0,005] e grupos overdenture [X2(6) = 17,732; p = 0,007], e entre halitose e tipo de prótese apenas em t0 [X2(6) = 12,894; p = 0,045]. A interação entre o tempo e o tipo de prótese interferiu significativamente nos valores médios do limiar de dor (p = 0,001). Na maioria dos pontos de tempos, a maioria dos participantes de cada grupo apresentava halitose clinicamente inaceitável. Após 30 dias de uso das próteses, o grupo overdenture apresentou menor limiar de dor em comparação ao grupo do protocolo de Brånemark.
ABSTRACT
Overdenture é uma prótese total que se caracteriza por usar apoios retentivos para que aumente sua estabilidade e retenção na cavidade bucal, gerando assim menor desconforto ao paciente e melhor adaptação. A Prótese overdenture dentossuportada necessita de elementos dentais remanescentes com canais tratados endodonticamente e que possuam suporte periodontal adequado. O objetivo deste relato de caso clínico é expor a sequência de confecção de uma prótese overdenture dentossuportada maxilar associada a uma prótese total convencional mandibular, com os passos clínicos detalhados por meio de uma abordagem teórica e visual. Esse tipo de reabilitação favorece a adaptação do paciente à nova condição, visto que o uso de próteses totais convencionais pode causar certo desconforto ao paciente devido à falta de retenção e estabilidade. Essa manutenção dos dentes remanescentes favorece à manutenção óssea e a futura decisão do paciente em optar pela instalação de implantes dentários, podendo confeccionar próteses implantorretidas (overdentures) ou implantossuportadas (protocolo).O Paciente demonstrou-se satisfeito com o resultado estético e funcional após a instalação da prótese concretizando que o tratamento é viável(AU)

A sobrevivência de pacientes com câncer de cabeça e pescoço vêm melhorando, entretanto, algumas deformidades podem ocorrer devido dos tratamentos cirúrgicos que geram mutilações bucomaxilofaciais como perda de dentes, estruturas do palato, língua ou assoalho, resultando em alterações na fonética, mastigação e deglutição. Nesses casos há a necessidade que seja realizado uma reabilitação protética buscando torná-los indivíduos com menos problemas sociais, psicológicos e físicos, visto que mais procedimentos cirúrgicos estão contra indicados para solucionar os efeitos colaterais gerados pelo tratamento das neoplasias. Esse tipo de reabilitação protética com prótese ou placa obturadora possibilita benefícios na fonética, facilita a convivência social e atividades nutricionais como alimentação e deglutição, permitindo ao paciente uma vida com menos constrangimentos. Este trabalho tem como objetivo relatar dois casos clínicos onde os pacientes foram submetidos a reabilitação com placa obturadora palatina feitos após cirurgias oncológicas. Os pacientes de gêneros diferentes e com comunicações buco-nasal similares receberam o mesmo planejamento reabilitador que foram confeccionadas a partir de um molde que foi enviado ao laboratório. Após a instalação foi possível verificar que houve sucesso no tratamento, notando uma melhora imediata comprovando a eficácia do método reabilitador(AU)
This paper relates two clinical cases where patients were recovered with a palatal splint made after oncological surgeries. Survival of patients and necks can occur, however, some deformities can occur during oral and maxillofacial treatment, such as the appearance of teeth, palate structures, mutilations or posterior jaws, leading to changes in aesthetics, surgery and swallowing. If the need to perform a prosthetic rehabilitation is necessary so that the results are seen with less problems, psychological and physical, that more procedures are performed so that the effects of neoplasms are contraindicated by the treatment. This type of prosthetic rehabilitation with prosthesis or obturator plate provides benefits in phonetics, facilitates social coexistence and nutritional activities such as eating and swallowing, allowing the patient a life with less constraints. Patients of different genders and with similar oral and nasal communications received the same rehabilitation plan that were made from a mold that was sent to the laboratory. After installation, it was possible to verify that the treatment was successful, noting an immediate improvement, proving the effectiveness of the rehabilitation method(AU)

A busca por naturalidade dos procedimentos restauradores em reabilitação oral tem contribuído para o desenvolvimento de vários tipos de materiais livres de metal ("metal free"). A confecção de próteses com estes sistemas totalmente puros, mostra-se como excelente alternativa restauradora, com potencial estético superior às próteses metalocerâmicas. É indiscutível que a tecnologia CAD/CAM (Computer-aided design/ Computer-aided manufacturing) vem se tornando realidade nos consultórios e laboratórios de Prótese Dentária de todo o mundo. Esta tecnologia possibilita o uso de cerâmicas e polímeros na fabricação de próteses, com qualidade e resistência mecânica satisfatórias, padronizando os processos, reduzindo custos e tempo clínico-laboratorial. A grande diversidade destes novos materiais restauradores livres de metal, com suas distintas propriedades estéticas e mecânicas, faz com que seja necessária uma seleção racional desses materiais, a fim de se alcançar a longevidade desejada do tratamento protético reabilitador. Dentre estes materiais, destacam-se as cerâmicas vítreas, as zircônias monolíticas, as cerâmicas infiltradas por polímeros e as resinas nanocerâmicas. O objetivo do trabalho foi avaliar os dados mais relevantes e atuais sobre as propriedades destes novos materiais, os sistemas disponíveis, suas indicações, limitações e seu uso associado com a tecnologia CAD/CAM. Esta revisão consistiu em uma pesquisa eletrônica da literatura publicada nos últimos 15 anos, nas bases de dados: Medline/Pubmed, Embase, Scielo, Bireme, Lilacs e BBO, utilizando-se os seguintes descritores do MESH: [CADCAM AND restorative materials AND monolitic] OR [Monolitic CAD-CAM restorative materials]. Concluiu-se que os materiais monolíticos obtidos pelo sistema CAD/CAM foram desenvolvidos para oferecer uma melhor adaptação e durabilidade das peças, com ótimas taxas de sobrevida e redução de tempo clínico e laboratorial, oferecendo ao paciente conforto, sessões clínicas mais curtas e restaurações de qualidade superior aos sistemas convencionais. Todos os materiais citados nesta revisão apresentaram vantagens e desvantagens, cabendo ao profissional selecionar o melhor material para cada situação clínica em específico, levando em conta os prós e contras de cada um(AU)

ABSTRACT Objective: This study aimed to evaluate the dimensional stability and maintenance of details of conventional and high stability alginates up to 5-day storage. Methods: Two types of alginates were selected (n=10) for this study, conventional (Hydrogum) and high stability alginates (Hydrogum 5), which were produced with the aid of a cylindrical metal block and a ring-shaped metal mold (Specifications 18, 19, and 25, ANSI/ADA). Ten images were obtained from the molds for the dimensional stability test, which were taken immediately after their production and at each different storage periods (15 min, 24 h, 48 h, 72 h, 96 h, and 120 h) by a digital camera. The specimens were kept hermetically sealed in plastic bags (23°C) and then used to obtain 140 (n=70) dental stone models, used in the detail reproduction test, in which the angular accuracy of three grooves (20 µm, 50 µm, and 75 µm) was observed at each period. The details reproduction accuracy was classified using a predetermined score classification. Measurements of dimensional changes were made in the Corel DRAW X6 program. The data were submitted to the Student's t-test (α?#8197;= 0.05). Results: A statistically significant difference concerning the size of the matrix was observed after 24h for both alginates, and a statistically significant negative linear dimensional change (contraction) was verified after 24 h of storage (1.52% for the high stability alginate, and 1.32% for the conventional alginate). The high stability alginate kept the full details for 72 hours, while the conventional alginate, for 24 h. Both alginates reproduced the 75 µm groove at all storage periods. Conclusion: Impressions made with both alginates presented satisfactory clinical results when the alginates were immediately poured.
RESUMO Objetivo: O presente estudo teve como objetivo avaliar a estabilidade dimensional e manutenção de detalhes de alginatos convencionais e de alta estabilidade por até 5 dias de armazenamento. Métodos: Para esse estudo, foram selecionados dois tipos de alginatos: convencional (Hydrogum) (n = 10) e de alta estabilidade (Hydrogum 5) (n = 10), sendo produzidos com o auxílio de um bloco metálico cilíndrico e um molde metálico em forma de anel (especificações 18, 19 e 25, ANSI/ADA). Para o teste de estabilidade dimensional, dez imagens foram obtidas imediatamente e para cada tempo de armazenamento (15 min, 24, 48, 72, 96 e 120 horas), realizadas por câmera digital. As amostras foram mantidas hermeticamente fechadas em sacos plásticos (23°C). Para o teste de reprodução de detalhes, as amostras foram utilizadas para obter 140 (n = 70 por grupo) modelos de gesso, sendo observada a precisão angular de três sulcos (20 µm, 50 µm e 75 µm) para cada período. A precisão da reprodução de detalhes foi classificada usando uma classificação de pontuação predeterminada. As medições das mudanças dimensionais foram feitas no programa Corel DRAW X6. Os dados foram submetidos ao teste t de Student (α = 0,05). Resultados: Foi observada diferença estatística em relação à matriz após 24h para ambos os alginatos. Uma mudança dimensional linear negativa estatisticamente significativa (contração) foi verificada após 24 h de armazenamento (1,52% para alginato de alta estabilidade; 1,32% para alginato convencional). O alginato de alta estabilidade manteve os detalhes completos por até 72 horas, enquanto o alginato convencional, por 24 horas. Os alginatos reproduziram o sulco de 75 µm para todos os períodos. Conclusão: As impressões feitas com ambos os alginatos devem ser imediatamente vazadas para se ter resultados clínicos satisfatórios.

O objetivo desse trabalho foi avaliar a satisfação e a qualidade de vida de pacientes desdentados que tiveram suas próteses totais mandibulares reembasadas com material resiliente (Ufi Gel SC, VOCO, Alemanha). Foram selecionados 20 pacientes desdentados divididos aleatoriamente nos grupos de reembasamento direto ou indireto (n=10). Foram aplicados dois questionários, o OHIP Edent para avaliar a qualidade de vida e um questionário desenvolvido para verificar a satisfação dos pacientes com o uso do reembasador. Os testes clínicos foram realizados em quatro fases durante o tratamento: inicialmente com as próteses totais sem intervenção, 30, 60 e 90 dias após o reembasamento. A análise de variância ANOVA demonstrou que houve uma diferença estatisticamente significante para o fator tempo tanto para a qualidade de vida como para a satisfação (p d" 0,05). Observamos que a qualidade de visa e a satisfação aumentaram após o reembasamento, mas não houve diferença entre os métodos de polimerização testados. O método de polimerização direto é mais simples, menos demorado e menos oneroso para o paciente. Portanto, se não houver diferença entre os métodos de polimerização a longo prazo, não há porque submeter o paciente ao reembasamento indireto(AU)
The aim of this paper was to assess the quality of life and satisfaction for edentulous individuals who had their complete dentures relined with a soft liner material (Ufi Gel SC, VOCO, Germany). A total of 20 patients were selected and divided into two experimental groups, one for a chairside procedure and one for a laboratorial reline (n=10). Two questionnaires were used, the OHIP Edent and a satisfaction form to assess information on the reline material. The tests were performed initially and at 30, 60 and 90 days after the reline. The analysis of variance ANOVA presented a difference for the period evaluation, the quality of life improved after the procedure, but there was no difference between the polymerization methods. The chairside procedure is more simple, faster and more practical for both, professionals and patients. Therefore, if there are no difference in long term results, there is no reason to the patient undergo the laboratorial reline process(AU)

Cirurgias de ressecção parcial ou total da maxila em pacientes oncológicos geram comprometimento funcional e estético, alterando a deglutição, mastigação, fonética e aspiração, diminuindo a qualidade de vida do paciente. Assim, o objetivo deste estudo foi descrever a reabilitação oral de um paciente com prótese total maxilar estendida e uma prótese total mandibular convencional. Tal paciente havia sido submetido à uma cirurgia de ressecção parcial do rebordo alveolar maxilar, sem comunicação bucossinusal, por ser portador de Carcinoma espinocelular grau I. Paciente do sexo masculino, 69 anos, procurou atendimento no Centro de Oncologia Bucal da FOA UNESP, para confecção de suas próteses, após dois anos da realização de sua cirurgia. Foi observado declínio do suporte labial no local onde havia sido feita a ressecção cirúrgica gerando comprometimento estético e funcional ao paciente. Desta forma, foi proposta a realização de confecção de prótese total maxilar estendida e prótese inferior convencional, as quais foram instaladas e ajustadas adequadamente. Após 1 ano de acompanhamento, paciente encontra-se satisfeito com o tratamento, o qual devolveu sua estética, função e fonética(AU)
Surgeries of partial or total resection of the maxilla in oncological patients generate functional and aesthetic impairment, altering swallowing, chewing, phonetics and aspiration, reducing the quality of life of the patient. Thus, the objective of this study was to describe the oral rehabilitation of a patient with maxillary total prosthesis and a conventional mandibular total prosthesis. This patient had undergone surgery of partial resection of the maxillary alveolar ridge, without bucosinusal communication, for being a carrier of grade I squamous cell carcinoma. A 69-year-old male patient sought care at the Oral Oncology Center of FOA - UNESP, for denture after two years of surgery. Decreased lip support was observed in the place where surgical resection had been performed, generating aesthetic and functional impairment to the patient. In this way, it was proposed to make a complete maxillary full prosthesis and conventional lower prosthesis, which were installed and adjusted properly. After 1 year of follow-up, the patient was satisfied with the treatment, which returned his aesthetics, function and phonetics(AU)

A fratura de côndilo mandibular é um dos tipos de traumas faciais mais comuns, podendo ser diagnosticado por diversos meios, sendo que uma variedade de planos de tratamentos podem ser instaurados. Este tipo de fratura configura também uma das etiologias da disfunção temporomandibular (DTM), portanto, é indispensável que o profissional realize exames minuciosos, inclusive por meio de exames complementares de imagem para o correto diagnóstico e conduta curativa, tanto da fratura, quanto da disfunção. Sendo assim, o objetivo deste estudo foi descrever um caso de fratura de côndilo mandibular não tratada seguida de DTM. Paciente de 36 anos do gênero masculino com histórico de acidente automobilístico há cinco anos, resultando em fratura de côndilo, com diagnóstico tardio e consolidação em posição inadequada buscou tratamento na Faculdade de Odontologia de Araçatuba - UNESP. A conduta por meio do uso de placa interoclusal levou à eliminação da sintomatologia dolorosa(AU)
The condylar fracture is one of the most common types of facial trauma and can be diagnosed by different methods, and a variety of treatment plans can be used. This type of fracture also constitutes one of the etiologies of temporomandibular disorders (TMD). Therefore, it is essential that the professional conduct thorough examinations, including complementary imaging tests for the correct diagnosis and treatment of the fracture and the dysfunction. Thus, the aim of this study was to describe a case of untreated condylar fracture followed by the development of TMD. A 36-year-old male patient with a history of automobile accident five years ago, resulting in condylar fracture, sought treatment at the Aracatuba Dental School - UNESP. The fracture had late diagnosis and consolidation in a wrong position. The conduct treatment through the use of occlusal splint led to the elimination of the painful symptomatology(AU)

OBJECTIVE: The aims of this study were to examine the trans- and postoperative systemic characteristics of patients undergoing dental implant surgery and to investigate the relationship between pre- and post- surgery anxiety levels. MATERIAL AND METHODS: Thirty-nine patients were analyzed in 3 call centers to determine anxiety levels, pain levels, and preoperative and postoperative histories using the State-Trait (STAI) questionnaire. RESULTS: A total of 93 dental implants were installed, with a success rate of 100%. The most frequently reported systemic disease was hypertension. There was a significantly higher rate of effective clamping (torque) to the mandibular bone than to the maxillary bone. The association between postoperative surgical complications and longer operative time was not significant, but there was a significant correlation between the alteration of mouth opening and daily routine activities and a significant decrease in anxiety levels between the day of surgery and the postoperative time point (p =0.006). CONCLUSION: A longer surgical time was associated with surgery-related complications and with a higher anxiety index on the preoperative evaluation.

The development of implant dentistry improved the possibilities of rehabilitation with maxillofacial prosthesis. However, clinically it is difficult to bond the silicone to the attachment system. OBJECTIVES: This study aimed to evaluate the effect of an adhesive system on the bond strength between acrylic resin and facial silicone. MATERIAL AND METHODS: A total of 120 samples were fabricated with auto-polymerized acrylic resin and MDX 4-4210 facial silicone. Both materials were bonded through mechanical retentions and/or application of primers (DC 1205 primer and Sofreliner primer S) and adhesive (Silastic Medical Adhesive Type A) or not (control group). Samples were divided into 12 groups according to the method used to attach the silicone to the acrylic resin. All samples were subjected to a T-peel test in a universal testing machine. Failures were classified as adhesive, cohesive or mixed. The data were evaluated by the analysis of variance (ANOVA) and the Tukey's HSD test (α=.05). RESULTS: The highest bond strength values (5.95 N/mm; 3.07 N/mm; 4.75 N/mm) were recorded for the samples that received a Sofreliner primer application. These values were significantly higher when the samples had no scratches and did not receive the application of Silastic Medical Adhesive Type A. CONCLUSIONS: The most common type of failure was adhesive. The use of Sofreliner primer increased the bond strength between the auto-polymerized acrylic resin and the Silastic MDX 4-4210 facial silicone.

The use of ocular prostheses for ophthalmic patients aims to rebuild facial aesthetics and provide an artificial substitute to the visual organ. Natural intemperate conditions promote discoloration of artificial irides and many studies have attempted to produce irides with greater chromatic paint durability using different paint materials. OBJECTIVES: The present study evaluated the color stability of artificial irides obtained with two techniques (oil painting and digital image) and submitted to microwave polymerization. MATERIAL AND METHODS: Forty samples were fabricated simulating ocular prostheses. each sample was constituted by one disc of acrylic resin N1 and one disc of colorless acrylic resin with the iris interposed between the discs. The irides in brown and blue color were obtained by oil painting or digital image. The color stability was determined by a reflection spectrophotometer and measurements were taken before and after microwave polymerization. Statistical analysis of the techniques for reproducing artificial irides was performed by applying the normal data distribution test followed by 2-way ANOVA and Tukey HSD test (α=.05). RESULTS: Chromatic alterations occurred in all specimens and statistically significant differences were observed between the oil-painted samples and those obtained by digital imaging. There was no statistical difference between the brown and blue colors. Independently of technique, all samples suffered color alterations after microwave polymerization. CONCLUSION: The digital imaging technique for reproducing irides presented better color stability after microwave polymerization.
