The success rate of resin-bonded fixed partial dentures is directly related to the adhesive system and the tooth preparation design for good retention. These resin-bonded bridges represent a prosthodontic alternative, based on their costeffectiveness, conservative techniques, and ease of laboratory manufacturing. Through a thorough review of the literature, this study aimed to report on cavity designs, types of materials used, and the advantages and disadvantages of the resin-bonded fixed partial denture. One of significant advantages of the resin-bonded fixed partial dentures is the conservation of the tooth structure, whereas its main disadvantage includes aesthetic limitations, given that the alloy may in fact be visible. Preparation design, cement type, and casting alloy type, as well as surface treatment, are among the factors that influence the longevity of resin-bonded fixed partial dentures. Treatments with resin-bonded fixed partial dentures present a bright outlook regarding the conservation of tooth structures, as well as a high level of success.

Periodontitis is a chronic inflammatory disease that results in the destruction of teeth and their supporting tissues with subsequent tooth loss. The replacement of missing teeth for implant-supported restorations has proven to be a highly predictable treatment method with good long-term prognosis. However, some consequences of tooth loss prevents dental implant placement in an ideal position, where regenerative procedures are necessary for this type of rehabilitation. Less invasive procedures such as conventional prosthesis emerge as a therapeutic option in cases where there is enough bone structure for implants and patient´s non-acceptance for invasive procedures. Thus, this paper aims to present the resolution of rehabilitation through a noninvasive and multidisciplinary treatment. One female patient referred to the clinic presented maladaptive bilateral mandibular fixed prostheses, endodontic lesions, gingival recession, and root sensitivity. For proper resolution of this case, an association among osseointegrated implants, fixed partial prosthesis, tooth extraction, and aesthetic periodontal procedures with the use of subepithelial connective tissue graft was proposed. After two years, the patient shows excellent aesthetics and chewing. Within the limits of this scenario, this paper discusses the various factors that may affect the choice of a particular treatment modality for the rehabilitation of edentulous single spaces.

The immediate complete denture is defined as a removable or partial denture made to be installed immediately after the extraction of the natural teeth. This type of prosthesis can be used for a short period of time, for aesthetic reasons, mastication, occlusal support, convenience or for the adaptation of the patients to the edentulous state, until the final prosthesis is installed. The objective of this study was to report a surgical and prosthetic rehabilitation planning of a patient by means of an immediate complete maxillary denture, and the results obtained with this treatment modality. The immediate complete denture is a necessary, well-established, useful and effective prosthetic procedure for patients who, inevitably, will present an edentulous state, despite it is a slightly more expensive and it requires more sessions for adjust

In many oral rehabilitation professionals seeking venture renew people smile. However, these procedures have functional implications and aesthetic criteria which must be satisfied so that the final result is predictable. The restoration of relations intermaxillary, phonetics, masticatory function, esthetics and patient comfort are the goals to be achieved. An effective way to achieve these goals when immediate reconstruction with permanent dentures is not possible, make use of a type of partial denture called overlay. Bruxism is a manifestation of biopsychological imbalance that affects the stomatognathic system, characterized by clenching and / or attrition of teeth together so centric or eccentric, can be manifestation of nocturnal or diurnal. Its effects can manifest themselves in different parts of the stomatognathic system, varying the severity of the damage as the resistance of the structures affected, the time of existence, its regularity and the general state of the wearer. The description of the steps followed in solving this case, in which the patient edentulous mandibular arch while the maxillary arch showed absence of teeth 16 and 26 and, except for the teeth 17 and 27, all other teeth showed wear very sharp in the sense denoting incisal cervical, severe impairment of the vertical dimension, the quality of masticatory function and a marked impairment phonetic, this case report aims to guide the beginning of a rehabilitation, as well as the transitional phase of treatment for recovery of functional and aesthetic relationships intermaxillary .

The purpose of this study was to evaluate the dental caries prevalence and the use and needs of dental prosthetic in pregnant women attending in the National Health System in northwestern city of São Paulo state. The sample involved women, between 3 and 9 months of gestation, who were taking prenatal care in Health Units. Those who consented (n = 119) were examined and interviewed by calibrated dentists. We used the DMF-T index and indicators of the use and needs of dental prosthetic. The average age of the pregnant women was 24.7 years, the majority brown (48.7%) with complete high school (60.5%). The average DMFT was 11.7 and 25.2% and 46.2% of them require upper and lower prosthesis, respectively. The oral health indices showed a high DMT-F and great need for dental prostheses. The results show the need for actions directed, with the aim of to improve the specialized attention to the health of mothers and their babies.

Foram eviscerados os globos oculares esquerdos de 32 ratos, linhagem Wistar, divididos em quatro grupos (A, B, C, D) constituídos, cada um, de cinco testemunhas e três controles. Nos animais-testemunha introduziu-se, dentro da capa córneo-escleral, uma esfera de resina acrílica (metilmetacrilato), previamente confeccionada e esterilizada por autoclavagem, ao passo que nos controles a cavidade eviscerada foi mantida sem prótese. Os ratos dos grupos A, B, C e D foram sacrificados respectivamente aos 7, 15, 30 e 90 dias de pós-operatório, quando os conteúdos orbitários esquerdos foram exenterados e preparados para o exame histopatológico. Observou-se que os animais-testemunha tiveram resposta inflamatória do tipo tecido de granulação ao redor da prótese de cavidade, com edema inflamatório da córnea especialmente nos grupos A e B, quando se iniciou a regressão da inflamação aguda. A cavidade orbitária manteve o tamanho em todos os grupos nos animais-testemunha e houve contração significativa nos animais-controle. Com estas observações, foi possível concluir que a esfera de resina acrílica é uma opção, de baixo custo e fácil confecção, para correção de defeito estético causado pela perda do globo ocular.

OBJETIVOS: Avaliar o posicionamento palpebral em portadores de cavidade anoftálmica com e sem prótese ocular externa, utilizando o processamento de imagem digital. MÉTODOS: Dezoito pacientes foram avaliados qualitativa e quantitativamente na Faculdade de Medicina de Botucatu - Universidade Estadual Paulista - UNESP, com e sem a prótese externa. Usando imagens obtidas por filmadora e processadas usando o programa Scion Image, mediu-se a altura do sulco palpebral superior, a altura da fenda palpebral e os ângulos palpebrais dos cantos interno e externo. RESULTADOS: Pseudo-estrabismo e sulco palpebral superior profundo foram as alterações mais freqüentes ao exame externo. Houve diferença significativa em todas as variáveis estudadas, com diminuição da altura do sulco palpebral superior, aumento da área da fenda palpebral e aumento dos ângulos palpebrais interno e externo quando o paciente estava usando a prótese externa. CONCLUSÃO: Todos os pacientes avaliados apresentaram algum tipo de anormalidade órbito-palpebral, o que reflete a dificuldade em se proporcionar ao portador de cavidade anoftálmica um aspecto idêntico ao que existe na órbita normal. O processamento de imagens digitais permitiu avaliação objetiva das dimensões óculo-palpebrais, o que poderá contribuir nas avaliações seqüenciais dos portadores de cavidade anoftálmica.

Foram avaliadas as técnicas radiográficas dentárias intra (TIB) e extrabucal (TEB) em 50 cães com doença periodontal, no intuito de padronizar os procedimentos de diagnóstico dessa síndrome. A TIB revelou que 16 animais não apresentaram lesões ósseas visíveis, enquanto a TEB apontou que 39 pacientes foram negativos para as mesmas lesões. em resumo, a TIB foi mais eficaz na detecção de sinais radiográficos, especialmente as chamadas lesões finas, que a TEB, sendo a técnica de escolha na síndrome periodontal.
