Description
Abdulaziz Gul and colleagues published a 2026 laboratory study comparing how much force different zirconia dental implant designs can withstand before breaking. Five designs were tested: a one-piece implant, plus bone-level and tissue-level two-piece implants fitted with either ceramic or titanium screws. Specimens were first loaded repeatedly in moist conditions to mimic chewing, then loaded once until they fractured, following an international testing standard. Fracture surfaces and crystal changes were examined microscopically.
Tissue-level two-piece implants were strongest, resisting about 775 newtons, ahead of one-piece implants near 606 newtons and bone-level designs near 498 newtons. Screw material made no significant difference overall. Where the implant sits relative to tissue and bone mattered far more than what the screw is made of. All designs passed levels the authors judge sufficient to justify further clinical study of ceramic implants.
