“…In cortical bone -the values of maximum v. Mises stress are higher on the loading side. The highest value of 7.57 MPa is on the middle (angled) implant 15 , and the anterior 25 has slightly lower values of 6.85 MPa. In the cortical bone around the distal implant 5, the values of maximum v. Mises stress are the lowest, 2.91 MPa.…”

“…On implants -On the loading side, the highest values of maximum v. Mises stress are on the middle implant 15 with values of 21.9 MPa, and on the front implant 25 with values of 31.3 MPa. The distal implant 5 on the same side has much lower values, less than 3.90 MPa.…”

Implant-prosthetic treatments provide better dental rehabilitation than other treatments. However, implant overload is considered a risk factor that may compromise the treatment. The aim of the study was to analyze the stress in the implants, cortical and spongiosus bone, at an equal ratio of suprastructure and implant (C / I 1/1) in All-on-6 implant concept in the mandible. Numerical tests were performed on a 3D model of the mandible, based on the finite elements method or finite elements analysis (FEA). Static simulated vertical forces of 100 N and oblique forces of 35 N at an angle of 45 degrees, were applied. The physical characteristics of biological tissues and component materials, as necessary data for model making, are taken from the literature. The study analyzed Von Mises stress in implants and peri-implant cortical and trabecular bone. The highest values of von Misess stress were observed in implants, then in cortical bone, and the lowest ones in trabecular bone. The stress has higher values and greater variations on the loading side. Oblique loads create greater stress. Von Misess stress does not exceed the limitation values of elasticity of the implants and peri-implant bone tissue. The results give a realistic vision of the stress, that can be used for implant-prosthetic treatments planning.

“…Most of the stress is found at the crestal region, as opposed to the apical part. [149] The maximum occlusal force for a complete denture wearer ranges from 5 -50 lb. People with implant-supported fixed prostheses can increase their maximum bite force by 85% within 2 months of implant treatment; it may further increase by more than 300% after 3 years.…”

“…The implant body has a high tendency to slide if shear force is applied and is considered to be the most unfavourable force, as it can cause damage to implants and the surrounding bone. [113,149] 2.7 Patient reported outcomes (PROs)…”
