Distúrbios articulares nos desdentados totais

Temporomandibular joint dysfunction play a negative role in a patient life quality standard. It is considered that the temporomandibular dysfunction either a multicausal phenomenon. A diversity signs and symptoms such as muscular pains, headaches, temporomandibular joint localized pain and joint noise may lead to difficulties of correct diagnosis. The clinical signals equally are distributed between the sex, however, the incidence in the feminine sex is a little bigger in relation to the masculine sex. The main etiological factors in the aged patient can be several, between them the bad occlusion, stress emotional and muscular hiperfunção. A confirmed time the dysfunction, can be used of the modification of prosthesis total inferior with reestablishment of the vertical dimension of occlusion for the treatment of muscles and ATM, before the set of teeth confection new. Later to the relief of the symptoms of the DTM they are carried through prosthesis new.Los disturbios de la articulación temporomandibular muestran un impacto negativo en la calidad de vida de sus portadores. Se considera que la disfunción temporomandibular sea un fenómeno de causas múltiples. La diversidad de las señales y síntomas presentados por los pacientes, como dolores musculares, cefaleas, dolores en la parte de la articulación temporomandibular (ATM) y ruidos articulares dificultan el diagnóstico clínico. Las señales clínicas son sentidas indistintamente del sexo, sin embargo, la incidencia encontrada en el sexo femenino es un poco mayor en relación al sexo masculino. Los principales factores etiológicos en pacientes seniles pueden ser varios, entre ellos la oclusión incorrecta, estress emocional e hiperfunción muscular. Una vez confirmada la disfunción, se puede modificar la prótesis total inferior con el reestablecimiento de la dimensión vertical de la oclusión para el tratamiento de la musculatura y ATM, antes de la confección de nueva dentadura. Después de aliviado los síntomas de la ATM seran realizadas las nuevas prótesis.Os distúrbios da articulação temporomandibular apresentam um impacto negativo da qualidade de vida de seus portadores.

Evaluation of the color stability of two techniquesfor reproducing artificial irides after microwave polymerization

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

The influence of chemical disinfection of two silicone types on dimensional changes and on the maintenance of details of plaster casts

A possibilidade de haver infecção cruzada através de moldes tornou necessária a desinfecção de materiais de moldagem, previamente ao vazamento de gesso. O propósito deste estudo foi avaliar a influência da desinfecção química com solução à base de glutaraldeído a 2% em modelos obtidos por duas marcas de gesso especial, por aspersão de dois tipos de material elastomérico de impressão, durante 15 minutos, analisados segundo testes de alteração dimensional linear e manutenção de detalhes. Os resultados, após análise estatística pelo teste de Tukey, mostraram haver alteração dimensional nos modelos de gesso obtidos a partir de materiais elastoméricos diferentes, independentemente da desinfecção química. _______________________________________________________________________________________ ABSTRACTThe possibility of cross-contamination by handling moulding impressions has made necessary the disinfection of moulding materials, before the plaster casting. The purpose of this study was to analyse the influence of chemical disinfection with a 2% glutaraldehyde-based solution, on plaster casts obtained with two brands of dental gypsum, by sprinkling it, for 15 minutes, on two types of elastomeric impression materials, in order to detect dimensional changes and maintenance of details. After the statistical analysis by the Tukey’s Test, the results indicated that the occurrence of dimensional changes in plaster casts obtained from different elastomeric impression materials, does not depend on chemical disinfection

Comparative analysis of reflection photoelasticity in mandible’s segment with or without base

Introduction and Objective: To analyze if axial loads of 50 N and 100 N, applied on an implant of 3.75 X 10 mm (Conexão-Jaú, SP, Brazil) fixed on the central portion of a prototype of the mandible with and without support base, generate isochromatic fringes of different intensity and ways. Material and methods: The sample was a segment of the mandible with 115 mm in length, 30 mm height,and 12 mm in thickness, from a block of #7 rose wax. This matrix was adapted to a modified articulator in such way that its base could or not keep contact with the lower arm of the articulator, simply by modifying the support axis. An implant was put perpendicular to the segment of the mandible’s body and then the photoelastic model obtained. The healing abutment was screwed to the implant to receive loads from 50 N to 100 N, with the model with or withoutcontact of its base with the inferior arm of the articulator. Results: Alterations in the reflections of the colors was observed when the implants had been submitted to loads of 50 N and 100 N with or without supported base. Conclusion: Based on the results, it can be concluded that during the photoelasticity analyses alterations in the color standards occurred depending on the support of the sample and the applied load.Introduction and Objective: To analyze if axial loads of 50 N and 100 N, applied on an implant of 3.75 X 10 mm (Conexão-Jaú, SP, Brazil) fixed on the central portion of a prototype of the mandible with and without support base, generate isochromatic fringes of different intensity and ways.

Phantom Eye Syndrome: A Review of the Literature

The purpose of this literature review was to describe the main features of phantom eye syndrome in relation to their possible causes, symptoms, treatments, and influence of eye amputation on quality of life of anophthalmic patients. For this, a bibliographical research was performed in Pubmed database using the following terms: “eye amputation,” “eye trauma,” “phantom eye syndrome,” “phantom pain,” and “quality of life,” associated or not. Thirteen studies were selected, besides some relevant references contained in the selected manuscripts and other studies hallowed in the literature. Thus, 56 articles were included in this review. The phantom eye syndrome is defined as any sensation reported by the patient with anophthalmia, originated anophthalmic cavity. In phantom eye syndrome, at least one of these three symptoms has to be present: phantom vision, phantom pain, and phantom sensations. This syndrome has a direct influence on the quality of life of the patients, and psychological support is recommended before and after the amputation of the eyeball as well as aid in the treatment of the syndrome. Therefore, it is suggested that, for more effective treatment of phantom eye syndrome, drug therapy should be associated with psychological approach
