초록

Purpose: The present study was to determine the stress distribution of an abutment screw according to implant abutment material.
Methods: This study was a tightening torque 10 Ncm, 20 Ncm, set to 30 Ncm, and a titanium alloy (Ti-6Al-4V), PEEK (polyetheretherketone), Endoligns (60% Carbon Fiber Reinforced PEEK) material of the custom abutment titanium alloy (Ti-6Al-4V) the stress distribution in the material of the abutment screw will be evaluated by the finite element analysis.
Results: Abutment screw most stress has been concentrated on the interface between the fixture and the abutment was also part of the interface that the threads are started. Depending on the abutment of the abutment screw Material von Mises stress values are shown differently. 10Ncm T10 under the tightening torque of 294.2 ㎫, P10 is 562.8 ㎫, appeared to E10 is 295.8 ㎫, 20Ncm tightening torque under T20 is 581.1 ㎫, P20 is 1125 ㎫, E20 was shown to 585.1 ㎫, 30Ncm tightening torque under T30 is 918.2 ㎫, P30 is 1795 ㎫, E30 has appeared 925.1 ㎫.
Conclusion: If the abutment is used as Endoligns, it was confirmed that the abutment screw exhibits of von Mises stress value is similar to the titanium alloy abutment.
