Implantes curtos em região posterior da mandíbula

The rehabilitation of edentulous areas with osseointegrated dental implants is a well-documented, predictable procedure in the literature, with high success rates. However, the lack of bone at the recipient bed or proximity to anatomic structures limits the rehabilitation procedure especially at the posterior mandible. Thus, short implants are an alternative treatment for such cases of severe bone resorption. The purpose of this study was to review the success rate of short implants, especially those based in the posterior mandible and to show a clinical case. A literature review was made on electronic databases PubMed and Bireme with articles published between the years 2005 to 2012, using the keywords "short dental implants". It was concluded that the success rates of short implants are similar to those presented by conventional implants but still related to their geometry and surface treatment. Also, short implants can be considered as a viable alternative for the rehabilitation of severely resorbed jaws. However, many authors consider that more research is necessary when a short implant is compared to a long dental implant.

Índice geométrico e perda de carga localizada em conexões de emissores "online"

The objective of this research is to present a study on a relationship between the local head loss in connection of emitters in pipes with different diameters used in drip irrigation, with the online geometry of the emitter connectors, that allows an easy quantification of such head loss regarding of the size of the connectors. The experiment was carried out according to the Reynolds Numbers at a turbulent flow interval, obtained by the variation of the pipe outflow at a constant temperature of water. The results indicated that the friction factor of the Darcy-Weisbach equation can be estimated by the Blasius equation with the coefficients b = 0.300 and m = 0.25, for the above mentioned pipes. The head losses produced by the connections of the emitters, in relation to the pipe without emitter, was of 62%. A relationship between the kinetic load coefficient (K) and the index of blockage (IO) provoked by the online connector is presented by an algebraic equation which shows a coefficient of adjustment of approximately 96%.

Simetria no ensino fundamental através da resolução de problemas: possibilidades para um trabalho em sala de aula

This paper presents an alternative way of working with the theme of symmetry in the elementary school classroom. The proposal is based on qualitative research developed in the Professional Masters degree program in Science and Mathematics Teaching. We conducted field-work consisting of applying a sequence of activities for students in the seventh grade. The sequence was developed from the perspective of mathematics teaching using problem solving, taking into consideration aspects relevant to the study of geometry, such as intuition and visualization. In carrying out the activities, the dialogues between students and teacher were recorded and later transcribed. For data analysis we used the procedures of phenomenology. When interpreting the data, we observed that the teaching of symmetry using problem-solving enhances learning. We also found that, in an investigative environment, students are able to identify properties, argue about the geometric characteristics, and justify their opinions.
