The Impact of Force Transmission on Narrow-Body Dental Implants Made of Commercially Pure Titanium and Titanium Zirconia Alloy with a Conical Implant-Abutment Connection: An Experimental Pilot Study

In situmicroradioscopy and microtomography of fatigue-loaded dental two-piece implants

“…Most taper implant-abutment connections show a higher fatigue resistance when compared with butt-joint connections but their maximum load bearing capacity is similar with approximately 400 N until failure (Dittmer et al, 2011(Dittmer et al, , 2012. High-cycle fatigue (HCF) with low loading forces up to 120 N revealed the occurrence of a plastic deformation of the implant-shoulder and within the implant-abutment interface (Rack et al, 2013;Wiest et al, 2015;Nelson et al, 2015). It is known that occlusal forces can amount up to 1000 N with a mean maximum biting force of 578 N at the implant-supported prosthesis side (Shinkai et al, 2007;Al-Omiri et al, 2014).…”

Impact of Intentional Overload on Joint Stability of Internal Implant‐Abutment Connection System with Different Diameter

“…The mating surfaces of abutment and implant are irregular, and the settling effect between those two surfaces makes them closer under compressive force. Also, compressive force could generate elastic and plastic deformation of the implant/abutment interface, inducing further insertion of the abutment . The axial displacement of the abutment can cause various biomechanical complications such as prosthesis misfit, unstable occlusion and prosthesis screw loosening .…”

“…16 To prevent these complications, many studies have focused on the amount of axial displacement after tightening torque or physiologic cyclic loading. [12][13][14][15][16][17] In the second molar area, the average occlusal force has been reported to be 450 to 550 N, 18 and maximum force to be up to 800 N in natural teeth. 19 Adequate fracture resistance has been reported even under overloading condition in ICC systems.…”
