The Study of Compression Shear Load of Implanting in Three Different Fastening Method

Abstract

The purpose of this study is to compare the differences between Shear compression load using shear compression loads tester (858 Bionix, MTS, USA) with fixed screws in the force of 30 N•cm using in four different fastening methods with implanting(N=5) fixture an abutment. As a result of the experiment, the compression load of YI Implant which is the compression load of Internal octagon connection Implant , Non submerged type taking morse taper of 8° was the highest as 1208.20 N•cm, that of Internal hexagon connection Implant which is submerged type taking morse taper of 11° was the lowest as 617.60 N•cm. The relevance of the shear compression load test which was done by four different fastening methods with implanting fixture an abutment, showed a statistically significant difference (p <0.001).

The Study of Compression Shear Load of Implanting in Four Different Fastening Method

“…The hardness of the implant, which is made of commercially pure titanium Grade with the same hardness, has to be compared by the mechanical properties of the implant according to the difference of the coupling method because it is determined by the properties of the alloy, however, previous studies were a mixture of commercially pure titanium Grade 3 and commercially pure titanium Grade 4, so there was a limitation of the comparison of the difference between the coupling method of the implant to the work [11]. The study the test specimen, but note that the study limitations shear compression load test using the other three implants signed with commercially pure titanium Grade 4 way with the same hardness produced by the implant, and have different mechanical characteristics of the coupling method was limited to a comparison of the pay-off phenomenon of the screw and the implant study [7,12], there is no research based on the differences between shear compression loads using commercially pure Titanium Grade 4 fixed the same hardness with different fastening methods with implanting fixture an abutment in the same vender.…”
