A prótese bucomaxilofacial visa a reabilitação de pacientes que sofreram mutilações na face, restituindo estética e autoestima. Este trabalho visa relatar o caso clínico de um paciente reabilitado com prótese oculopalpebral após sofrer exenteração de órbita, decorrente de um carcinoma espinocelular em pálpebra inferior direita. Paciente, gênero masculino, 56 anos, procurou atendimento odontológico queixando-se de desconforto estético do rosto. Ao exame clínico foi observada ausência do globo ocular, pálpebras e arco superciliar do lado direito, por isto, foi planejada a confecção de uma prótese oculopalpebral. Foi realizada moldagem dos terços superior e médio da face, obteve-se o molde em alginato e, posteriormente, o modelo em gesso. Em seguida, foi confeccionado um globo ocular caracterizado em resina acrílica termopolimerizável. Posteriormente realizou-se, sobre o modelo de gesso, a escultura da área amputada utilizando-se plastilina e cera e após prova e ajustes no paciente, inclusão do conjunto modelo/escultura em mufla e contramufla, com posterior eliminação da peça esculpida. Foi selecionada a cor da pele do paciente e misturou-se uma base ao silicone, que foi incluído na mufla para prensagem. Após a vulcanização do silicone, foram realizados os acabamentos, caracterização e instalação da prótese. Na proservação o paciente relatou grande satisfação com a reconstituição da estética facial. Conclui-se que a prótese bucomaxilofacial é uma alternativa satisfatória para a reabilitação de pacientes que sofreram mutilações faciais, pois restabelece a estética facial, autoestima e convívio social.    Descritores: Prótese Maxilofacial; Olho Artificial; Reabilitação; Carcinoma de Células Escamosas.

ABSTRACT Midfacial defects developed due to partial or total maxillectomy surgeries performed to remove tumors in the oral or nasal cavity. Large midfacial defects usually restored with a facial prosthesis to restore esthetics, form and function. Retention of a large facial prosthesis is a major concern to the prosthodontist because of its size and weight. This clinical report describes magnet retained intraoral-extraoral combination prosthesis for a large midfacial defect. This article also describes a technique to fabricate a hollow light-weight acrylic resin framework supporting an overlying silicone layer for the facial prosthesis.

An alternative to aqueous chemical fixation consists in immobilizing physically the specimen by freezing it as fast as possible without using any cryoprotectant. This Fast Freeze Fixation (FFF) followed by Freeze Substitution (FS) avoids osmotic artefacts due to the slow penetration of liquid chemical fixative. Associated with Immuno-Gold labeling (IGS), FFF-FS allows a more precise localization of antigens.Using the bioluminescent bacteria Vibrio harveyi, a comparison of IGS with an antibody directed against its luciferase (enzyme of the luminescent reaction) has been done after liquid chemical fixation versus FFFFS. This later technique, beside an expected improvement of the ultrastructure always shows a better preservation of antigenicity and a lower background. In the case of FFF-FS technique (Figure 3):–labeling in acrylic resin (LRWhite) is 2 to 4 fold more intense than in epoxy resin (Epon),–but the ultrastructure is always better in Epon.–but the ultrastructure is always better in Epon.–The addition of fixatives in the substitution medium, results in a decrease of labeling which is more important in the case of a mixture of fixatives than with osmium tetroxide alone; with one exception: the substitution with glutaraldehyde which produces a dramatic increase in the density of the labeling but also, at the same time, a swelling of the cells of about 30%.

Thermal and self-curing acrylic resins are frequently and versatilely used in dental medicine since they are biocompatible, have no flavor or odor, have satisfactory thermal qualities and polishing capacity, and are easy and fast. Thus, given their widespread use, their fracture resistance behavior is especially important. In this research work, we comparatively analyzed the fracture resistance capacity of thermo and self-curing acrylic resins in vitro. Materials and Methods: Five prosthesis bases were created for each of the following acrylic resins: Lucitone®, ProBase®, and Megacryl®, which were submitted to different forces through the use of the CS® Dental Testing Machine, usually mobilized in the context of fatigue tests. To this end, a point was defined in the center of the anterior edge of the aforementioned acrylic resin bases, for which the peak tended until a fracture occurred. Thermosetting resins were, on average, more resistant to fracture than self-curable resins, although the difference was not statistically significant. The thermosetting resins of the Lucitone® and Probase® brands demonstrated behavior that was more resistant to fracture than the self-curing homologues, although the difference was not statistically significant. Thermosetting resins tended to be, on average, more resistant to fracture and exhibited the maximum values for impact strength, compressive strength, tensile strength, hardness, and dimensional accuracy than self-curing resins, regardless of brand.
