Abstract
The Mechanical Engineering supplies new technologies to Odontomedical Sciences in oral rehabilitation processing, in which patients can rescue their self-esteem and welfare. In this investigation, pig jawbones are used to simulate human bones by homology, focusing on the wear. Knowledge bridges between specific fields of Science seeks to develop methods to reduce future problems caused by using an implant (screw-loosening, screw-fracture, base-fracture and so). In this paper, it is intended to help implants professionals to better understand the wear and its impacts on the implants by taking into account generally underestimated bone reaction to the pH environment, especially in dentistry that has huge variation due to different feeding. For the procedure, firstly, wear in different pH environments have been investigated and secondly its impacts on the backlash phenomena both in function of the number of cycles. Wear rate by mass loss and Backlash were discussed. Aiming help this assessment, Sound Pressure Level (SPL) and Global Vibration Speed (GVS) were also analysed. It was observed that an basic environment is the best when the main objective of the implant is to be firm since this environment provides an smaller backlash phenomena.
