Ceramic implants advantages
More sustainable/Less possibility of Peri-Implantitis
Less plaque accretion than on titanium. This reduces the risk of peri-implantitis as well as cardiovascular diseases and strokes.1
More natural
Bones and gums integrate better with zirconium oxide ceramics.2
Healthier
Z-SYSTEMS implants are metal-free, biocompatible, conduct neither heat nor electrical energy, and cause no irritation to the immune system.3
More aesthetic than titanium implants
Thanks to the white material, no gray shadows are visible even with thin or receding gums which can occur in described cases.4
