Analysis of torque and torque after fatigue in dental implants

Oral rehabilitation through osseointegrated dental implants has been a major milestone in dentistry. Characterization and understanding of the properties of this biomaterial has been a great incentive in research. The stability between the two pieces, intraosseous screw and prosthetic abutment, is of paramount importance in the guarantee of longevity in these rehabilitations. Dynamic tests, simulating masticatory action on this device demonstrating the indications within safe limits are necessary. This work analyzed the torque and distorque of these parts with and without fatigue tests, according to ISO 14801. In this analysis it was used an electronic micro torquemeter, built in house, which captures data through strain gages, then processing data through National Instruments software. This allowed the obtention of data with quality and quantity meaning accurate results. The results showed, in all cases, that the threaded parts suffer a loss of torque when the torque was measured after chewing simulation.
