Tooth replacement with biologically sound implant materials continues to grow in popularity. Accordingly, the demand for a suitable alternative to titanium alloys is increasing. Thanks to the excellent biocompatibility and enhanced aesthetic outcome, more and more implantologists and patients show a preference for ceramic implant materials.

For many patients, the choice of a natural material is a high priority in dental implantology. While titanium is a functional choice for dental implants, some patients develop adverse reactions to metals1,2,3 or experience a discoloration of the gums4,5.
Ceramic implants are 100% metal-free. Therefore, dental professionals may find a viable solution with ceramic dental implants1,2 for their patients with metal sensitivity. Ceramics show excellent biocompatibility6,7,8 and are chemically stable in a physiological environment9. They are unlikely to trigger inappropriate immune reactions after implantation.6,7,3
Ceramic materials come in different shades of white mimicking the natural colouring of the tooth. For patients with thin gums, there is no risk of grey colouring shining through (tattooing) as it can occur with metal implants4,5. Ceramic materials do not release metal ions, and therefore do not cause grey stains along the gumline10. The most commonly used materials for dental implants are Zirconia (TZP) and Alumina Toughened Zirconia (ATZ) ceramics.
With ceramic dental implants in your portfolio, you can offer your customers a natural and hypoallergenic choice of dental implants for excellent aesthetic results.
