dc.description.abstract | The major problems for the osseointegration of dental implants are the loosening of the
screw that fixes the dental implant to the abutment and the micromovements that are generated
when mechanical loads are applied. In this work, torque differences in the tightening and loosening
of the connection screws after 1 cycle, 10 cycles and 1000 cycles for 4 dental implants with 2 external
and 2 internal connections were analyzed. The loosening of 240 implants (60 for each system) was
determined using high-precision torsimeters and an electromechanical testing machine. A total of
60 dental implants for each of the 4 systems were inserted into fresh bovine bone to determine the
micromovements. The implant stability values (ISQ) were determined by RFA. The mechanical loads
were performed at 30 from 20 N to 200 N. By means of the Q-star technique, the micromovements
were determined. It was observed that, for a few cycles, the loosening of the screw did not exceed
a loss of tightening of 10% for both connections. However, for 1000 cycles, the loss for the external
connection was around 20% and for the internal connection it was 13%. The micromovements showed
a lineal increase with the applied load for the implant systems studied. An external connection
presented greater micromotions for each level of applied load and lower ISQ values than internal
ones. An excellent lineal correlation between the ISQ and micromobility was observed. These results
may be very useful for clinicians in the selection of the type of dental implant, depending on the
masticatory load of the patient as well as the consequences of the insertion torque of the dental
implant and its revisions. | es |
