• Studies on the Influence of Surface Treatment for Mechanical Strength of Implant and Tightening Strength of Abutment

抄録

Platon implant (Platon Japan) is surface-treated with blasting techniques so that the properties of pure titanium are not damaged.<br/> Moreover, it has several morphological devices to increase the strength of its neck and the connection of its head and fixtures.<br/> In this study, 2 points, (1) the strength of the implant neck and (2) the tightening and returning torque of the junction were examined.<br/> The universal tester for test of the strength of the implant neck and torque tester for testing the tightening and returning torque of the junction were used. Implants of the same shape performing plasma-spraying techniques were compared with Platon implant.<br/> 1) The maximum load at which a crack occurred in the implant was 130.30±7.34 MPa (N=5), the maximum point strain was 45.99±4.90%, the maximum point stress was 73.86±4.16 MPa, and the maximum point elongation was 1.49±0.16 mm.<br/> The corresponding figures for the control implant were 115.06±8.73 MPa (N=3), 26.52±3.53%, 68.08±0.35 MPa, and 0.86±0.11 mm. By examining the parameters with the umpaired t-test at the probability level of 5%, significant differences were shown in the maximum load, the maximum point strain, and the maximum point elongation.<br/> 2) In the implant head fixed at the implant body,the returning torque was 2.97±0.18, 3.47±0.40, 4.37±0.58, and 4.68±0.57 kg/cm when the tightening torque was 2.0, 2.5, 3.0, and 3.5 kg/cm, respectively. Therefore, the returning torque was greater than each of the specified tightening torque. By examining the combinations with the unpaired test at the probability test of 5%, significant differences for all of these figures. were shown. These results indicate that the Platon implant may have high strength and provide favorable clinical results.
