Title: PLA (Polylactic Acid) scaffold printed by 3D tecnologie and funcionalized by plasma of oxygen

Abstract:

The purpose of tissue engineering is to repair, replace, create or regenerate tissues and organs. To this end, PLA (Polylactic acid) meets the interesting physical properties, as well as biodegrability and biocompatibility. To create a scaffold with PLA, we use rapid prototyping. This new field of research is a versatile technique for generating large quantities polymer shapes and sizes. To promote and increase properties such as hidrofilicity, adhesion and proliferation, we must work the surface with oxygen plasma. Nowadays, it is necessary to have biomaterial, which allows tissue engineering to construct and mold for 3D technology to support cells to repair organs with biocompatibility, chemical and physical properties that make it possible for the surface to be functionalized.

Biography:

I´m a dental implant specialist by Uningá/Bauru –São Paulo – Brazil since 2011.
I have a master of a degree in odontology sciences with an emphasis in implantology by the University of Araraquara – São Paulo – Brazil.
Currently, I´m studying for a Ph.D. at the University of Araraquara – São Paulo- Brazil where I have been conducting a research with polymer biomaterial and additive manufacturing. We print a 3D scaffold of PLA (polylactic acid) and make functionalities in their surface to optimize osseointegration and biocompatibility of the material to the human body.
My research line is to study bone substitutes: beta-tricalcium Phosphate, lyophilized xenogenic bone, and natural polymers. Therefore my research area is Dental Biomaterials and Bioengineering
