内容記述 |
The cantilever condition occurring in implant bodies during food−mastication was evaluatedusing JIS type 2 titanium plates of 0.8 (T08), 1.0 (T10), and 2.0 (T20) mm in thickness, according to a method similar to the three−point bending test. A tablet was set in the intermediate area of each titanium plate. The distance between abutment teeth was changed from 10 to 45 mm, load was applied to the tablet using a universal testing machine, and the deflection volume of each plate at the time of tablet fracture was measured. The relationship between the thickness of titanium plates and deflection volume and that between the distance between abutment teeth and deflection volume were compared and evaluated. As a result, during tablet mastication, plastic deformation of T08 occurred when the distance between abutment teeth was 15 mm, and that of T10 occurred when the distance between abutment teeth was 25 mm ; however, plastic deformation of T20 did not occur when the distance between abutment teeth was within 45 mm. Furthermore, when plastic deformation occurred, the deflection volume of the JIS type 2 titanium plate rapidly increased, exceeding the calculated value in the three−point bending test. These results revealed that, when JIS type 2 titanium bridges with a long distance between abutment teeth are set to implant bodies, it is necessary to set their thickness to more than 2 mm. Furthermore, to avoid the cantilever condition in implant bodies, the minimum requirement was considered to be that plastic deformation of the superstructures does not develop during food mastication. |
