Strength: Zirconia dental implants
4. Strength
Minamizato et al investigated the compressive strength of the blade type of zirconia dental implants with tunnels drilled by laser process, and found that specimens with tunnels showed lower compressive strength (237 kg/mm2) than specimens without tunnels (371.5 kg/mm2). They concluded that zirconia blades had adequate strength in occlusion.
Kohal et al evaluated the frac...
