Analizar las posibilidades auditivas reales de cada uno de los niños de la muestra. Establecer para cada grado de pérdida auditiva las perspectivas educativas y de comunicación que se infieren de la situación educativa real: discriminación sin lectura labial, apoyos específicos complementarios, etc. Redacción de un informe individual explicando las características auditivas con y sin audífonos y las posibilidades de audición y discriminación de la palabra. Establecer para cada grado de pérdida auditiva el método óptimo de obtención de ganancia para la adaptación protésica. 80 niños escolarizados en centros de integración, centros específicos para sordos y en colegios normales, con edades comprendidas entre 2 y 15 años. Consta de tres fases: el estudio audiológico (precontrol), la modificación de la adaptación protésica y la observación de los casos (postcontrol). Se redacta un informe individual en el que se explican las características y posibilidades auditivas del niño en estudio, basado en el resultado de las pruebas realizadas, que se entrega a padres y maestros o logopedas para que puedan elegir las actividades que cada niño en particular puede realizar. Tipo de datos obtenidos: a) relativos a la situación auditiva real del niño en estudio y sus posibilidades óptimas de audición, así como su posibilidad auditiva después de realizadas las modificaciones protésicas oportunas; b) posibilidades educativas en relación con la situación auditiva del niño: percepción e identificación de fonemas, nivel de articulación, discriminación sin lectura labial, molestias en ambientes ruidosos (aula, recreo, etc.) que llevan a disminuir el volumen del audífono, etc. Las variables más importantes son: edad, sexo, grado y tipo de pérdida auditiva, edad de detección e instalación de la hipoacusia, intensidad de habla normal, edad de adaptación de audífonos y sus tipos, umbral de audición precontrol y postcontrol. Los niños hipoacústicos profundos son detectados más precozmente que los niños con hipoacusias de menor grado. Una adaptación protésica temprana proporcionará al niño la posibilidad de obtener un umbral de audición óptimo. La mayor parte de los niños utilizan adaptación biaural de audífonos, permitiéndole la audición estereofónica. Los errores de adaptación protésica más frecuentes encontrados han sido la adaptación de audífonos monoaural, el exceso de salida máxima de audífono, excesiva ampliación en frecuencias graves, la adaptación incorrecta de modelos y una ampliación insuficiente. En los casos en los que fue posible realizar las modificaciones pertinentes, la mejoría auditiva que presentaron los niños repercutió favorablemente en el ámbito escolar.

Radipherpus protheses are a means of treatment for malignant tumor-carrying patients. These protheses are used in cases of brachytherapy or external actinotherapy by contact and allow treating them with high radiation doses that are quickly released from the areas next to tumor, so that the radiations be restricted to the affected region, without the emissions damaging or destroying the soft tissues. Based on these considerations, the present paper was aimed at making literature review on the use of radipherous protheses for the treatment of head and neck neoplasias. © 2006 1995, Editorial Ciencias médicas.

The study of techniques to reach aesthetics in the anterior region when using osseointegrated implants is of great importance. A literature review was made to compare effivciency and suitability of immediate provisionalization in re-opening of osseointegrated implants with respect to the set time (use of standardized cicatrizants and emergency profile cicatrizants). Immediate provisional denture in the phase of re-opening makes the restoration of the gingival contourn quicker when compared to the use of cicatrizants without intermediate phases required. © 2008 1995, Editorial Ciencias médicas.

Facial prostheses are a integral part of rehabilitation of patients underwent face damages, being of pathologic, traumatic or congenital origin. Although success of treatment with facial prostheses is associated with artistic ability of professional to reproduce lost structures, we can not to obviate the good adaptability of prostheses regards association of material and techniques used to make buccomaxillofacial prostheses.

The purpose of present study was to analyze the effect of pigmentation and chemical disinfection on the initial and the permanent deformation of two silicones (Silved Selant and Brascoved) for facial prosthesis. Initial and permanent deformation tests samples (20 mm × 12.5 mm) were made following the manufacturer's instructions. For each silicone (n= 40), ten samples were used for pigmentation with make up power, ten with iron oxide, ten with ceramics power and tem were tested without pigmentation. Five samples of each group were submitted to chemical disinfection using a 2 % Chlorhexidine spray. All samples were immersed in physiological saline and stored in an oven at 35 ° ± 1 °C. After 90 days, the samples were submitted to initial and permanent deformation tests using a dial indicator. For both properties, data were analyzed by Tukey's test (a= 0.05). The results showed that all the materials had initial and permanent deformation regardless of pigmentation and chemical disinfection. The groups were used for pigmentation with iron oxide showed less initial and permanent deformation when were submitted to the chemical disinfection regardless the silicone used.

Nowadays, aesthetics is very appreciated in the social context and a attractive smile is the object of desire in most of patients requiring prosthesis treatment. In case of removable prosthesis, total or partial, this feature is more significant since some or all teeth may be absents. Implants leading to a significant improvement in relation to function and comfort of removable prosthesis users, but the aesthetics of these prostheses had little attention in the current scientific literature. Thus, the aim of present article was to make a review of the literature on the aesthetic features related to rehabilitation with removable prostheses. In present study we found as significant factors for the aesthetics in removable partial and total prostheses: Selection of artificial teeth and their arrangement, characterization of acrylic resin basis and also the types and location of retainers for the removable partial prostheses. We conclude that the involvement and the aesthetic knowledge during the appropriate planning of this process is responsibility of the professional.
