In this case report, a single tooth restoration with the NobelPearl implant system is presented in detail by Prof. Dr Michael Gahlert.

Case presentation

A 35-year-old female patient with a tooth gap (#25) came to my outpatient consultation, and she wanted to be informed about single-tooth restoration options. The patient had researched beforehand about ceramic vs titanium dental implants and stated explicitly that she did not want to have a titanium implant placed. After clinical and radiographic diagnostics, the patient was informed about implantation with a two-piece 100% ceramic implant. The anatomical conditions were optimal so that the implantation could be carried out. The NobelPearl ceramic implant was chosen as the medical device, as the carbon-fiber reinforced PEEK screw, VICARBO®, is able to provide secure fixation of the abutment, as well as a complete metal-free restoration.

The postoperative healing period proceeded without complications and the definitive prosthetic restoration could be completed after a successful osseointegration period of three months. A conventional analogue impression was taken by means of an impression post that was screwed to the implant, which created the prerequisites for the all-ceramic crown. In the case presented here, the all-ceramic abutment was screw-retained, and the ceramic crown cemented with Ketac™ Cem Glass ionomer cement.

The result was beautiful and highly esthetic. There were no irritations of the peri-implant mucosa and the papillary structure in the interdental space was quite pronounced.


The NobelPearl implant system made of high-strength alumina toughened zirconia (ATZ) represents the latest development when it comes to two-piece ceramic implant systems with microrough surfaces. Different all-ceramic abutments can be chosen, which enables prosthetic flexibility. The fixing of the abutment parts with a carbon screw has been tested for its safety of use. Owing to this unique feature, NobelPearl ceramic implants allow for completely metal-free restorations and should be considered as a serious future alternative to established two-piece titanium implants.
