The Dallas Experiment - Comparison of Screw Torque ON1 vs All on 4

[@miroslavmarinkovic3539]

Thank You for this experiment. Very well explained. I would have one question, if You would be so kind to answer: If You would have some doubt about some unfitting of the definitive bridge on multiunit abutments and You now know that prosthetic screws have so high strenght (over 50-60 Ncm), what would brake first, in Your opinion? The screw, the multi unit abutment or the implant? I am asking because there is no evidence based studies that can show us that. Thank You in advance

this is not a multiunit screw that is so strong. This is an On1 abutment screw. I try to use a splint to make the forces low at night.

After using these screws for 14 years they rarely fracture. You need to do verification with schfield test to have it passive.
