Previous issue date: 2009-03-26 / This work aims to develop a methodology for analysis of images using overlapping, which assists in identification of microstructural features in areas of titanium, which may be associated with its biological response. That way, surfaces of titanium heat treated for 08 (eight) different ways have been subjected to a test culture of cells. It was a relationship between the grain, texture and shape of grains of surface of titanium (attacked) trying to relate to the process of proliferation and adhesion. We used an open source software for cell counting adhered to the surface of titanium. The juxtaposition of images before and after cell culture was obtained with the aid of micro-hardness of impressions made on the surface of samples. From this image where there is overlap, it is possible to study a possible relationship between cell growth with microstructural characteristics of the surface of titanium. This methodology was efficient to describe a set of procedures that are useful in the analysis of surfaces of titanium subjected to a culture of cells / O presente trabalho tem como objetivo desenvolver uma metodologia de an?lise de imagens, utilizando sobreposi??es, que auxilie na identifica??o de
caracter?sticas microestruturais, em superf?cies de tit?nio, que possam estar associadas com a sua resposta biol?gica. Desse modo, superf?cies de tit?nio
tratadas termicamente de 08(oito) diferentes maneiras foram submetidas a um ensaio de cultura de c?lulas. Buscou-se uma rela??o entre os gr?os, textura e
contornos de gr?os da superf?cie de tit?nio (atacada) procurando relacionar com o processo de prolifera??o e ades?o. Foi utilizado um software open source para a
contagem das c?lulas aderidas ? superf?cie do tit?nio. A justaposi??o das imagens antes e ap?s a cultura de c?lulas foi obtida com o aux?lio de impress?es de micro-dureza feita sobre a superf?cie das amostras. A partir desta imagem onde h? a sobreposi??o, ? poss?vel o estudo de uma poss?vel rela??o entre o crescimento celular com as caracter?sticas microestruturais da superf?cie de tit?nio. Essa metodologia se mostrou eficiente ao descrever um conjunto de procedimentos que s?o ?teis na analise de superf?cies de tit?nio submetidos a uma cultura de c?lulas
