Two-Piece Ceramic Implant Solution Promises Natural Aesthetics

Dentistry Today


Designed to serve as an alternative to titanium implants, Nobel Biocare’s NobelPearl is 100% metal-free. The two-piece ceramic implant with a cement-free internal connection targets soft-tissue attachment with low inflammatory response as well as aesthetics that offer the look and feel of natural teeth. 

The implant’s zirconia material especially benefits patients with a thin mucosal biotype, Nobel Biocare reports. Studies have shown that microcirculatory dynamics in peri-implant mucosa around zirconia are comparable with those around natural teeth, the company says. Also, the NobelPearl has demonstrated low affinity for plaque, Nobel Biocare says.

The NobelPearl offers greater restorative flexibility compared to one-piece or cemented ceramic implants due to its two-piece, reversible cement-free internal connection, the company says. The Inter-X internal connection is specifically designed for ceramic implants.

While the very strong ATZ ceramic absorbs compressive forces, the VICARBO screw made of carbon fiber-reinforced PEEK withstands tensile forces thanks to its continuous longitudinal carbon fibers, according to the company.

Risks of excess cement during intraoral cementation, often associated with soft-tissue inflammation and the development of peri-implant mucositis and peri-implantitis, can be avoided, Nobel Biocare says.

Combined with the tapered drill protocol, the NobelPearl’s thread design and tapered implant shape have been designed to achieve high primary stability. Osseointegration is achieved with the help of the hydrophilic sand-blasted and acid-etched ZERAFIL surface as well as the partially machined collar.

No sintering or finishing takes place during the final shaping of the implant, Nobel Biocare says, so a high level of dimensional precision and accuracy can be achieved. Plus, the company says that it has seen an increase in its implants’ survival rates thanks to the continuous development of its manufacturing partner, Dentalpoint AG.

Nobel Biocare further says that the NobelPearl gives dental professionals everything they need for a successful start in implantology. It is available for a broad range of indications, from single to multiple unit, and follows established workflows for two-piece implants.

The NobelPearl also will be integrated into the company’s digital workflow, which includes treatment planning with the NobelClinician Software and guided implant surgery with NobelGuide pilot drilling. Clinicians will be able to offer the NobelPearl Ceramic Base CAD/CAM solution using DTX Studio design software later this year as well.

“The demand by patients for ceramic implants has been steadily growing. With NobelPearl, we are proud to finally bring the first completely metal-free screw-retained two-piece implant system to the market,” said  Hans Geiselhoringer, president of Nobel Biocare.
