Abstract

The primary stability is one of the factors most important for the success of the osseointegração in the implantodontia, and the control of the insertion torque and assays of pulling up are of great importance for the quantification of the same one. The proposal of this study will be to after verify the primary stability of implantations with different formats and treatments of surface through the correlation between insertion torque and force of pulling up as well as the analysis of morphologic and superficial alterations accomplishment of this assay, through Electronic Microscopy of Varredura (MEV). For the accomplishment of the study 4 different types of implantations will be used: Máster Screw, Máster Porous, Máster Conect Air, Máster Conical Conect, eight implantations of each type will be inserted using kits surgical in the sequence of fresas indicated for the manufacturer in artificial bone (poliuretana). Before the insertion the screws they will be fotomicrografados in Electronic Microscopy of Varredura (MEV), Mark: Zeiss; Model: EVO50 with increase of 35 times. During the insertion the torque will be surveyed and after the insertion and pulling up by means of a Universal Machine of Assays (EMIC MEM 2000) will be, analyzed again in MEV. After the pulling up assay the results will receive treatment statistical and the MEV images will be evaluated qualitatively.
