ABSTRACT

Implants in craniofacial reconstructions improve prostheses retention and stability, comfort, and safety for the patient. According to biomechanical principles, the treatment success regarding osseointegration maintenance depends on an adequate surgery technique associated to a retention system that provides favorable tension distribution to implants. Implants in the mastoid area are a very important aid for retention of auricular prostheses. Color stability of resin and silicone is an important factor for longevity of auricular prostheses, and the high degree of satisfaction of patients with head and neck defects receiving epithesial reconstruction in the maxillofacial region is demonstrated.

ABSTRACT

Cancer is regarded as abnormal cellular multiplication; it is not controlled by the organism, and its cells present a differentiated DNA. Initially, the disease does not show clinical signs, but it can be diagnosed by laboratory examinations. When tumors are present in the maxillofacial area, the carrier can lose structures in this area, resulting to the carrier's social environment exclusion. This article aims to show incidences and causes of malignant neoplasias in the maxillofacial area.

ABSTRACT

A proposta deste estudo foi avaliar a rugosidade superficial de duas técnicas de moldagem com dois silicones de condensação (Zetaplus-Zhermack e Clonage-DFL) densos e fluídos sobre a influência da desinfecção química com solução à base de clorexidina 2 por cento (aspersão por 5 minutos). Foram confeccionados 56 corpos de prova que foram divididos em 8 grupos, sendo que metade foi submetido à desinfecção com solução a base de clorexidina 2 por cento antes das leituras do teste de dureza. Os corpos de prova foram submetidos ao ensaio de rugosidade superficial com auxílio de um rugosímetro digital (modelo RP100). Para cada corpo de prova, foram realizadas três leituras em diferentes sentidos e, transformadas em valores médios e analisados através de modelo de análise da variância e as médias comparadas pelo teste de Tukey (p>0,05). Não houve diferença estatisticamente significativa quando analisado os tipos de materiais utilizados independentemente da técnica de desinfecção química e houve diferença estatisticamente significativa quando analisado a técnica e desinfecção química independentemente das outras variáveis.
