digital technology in fixed implant prosthodontics case report | Fig. 22 Fig. 23 Fig. 24 Fig. 25 Ceramic fragments were prepared for teeth 12, 11 and 21 with diamond drills and ultrasonic tips; tissue control was carried out in the region and the impres- sion post was installed on the implant and custom- ised, so that the surrounding soft tissue could be accurately reproduced (Figs. 12 & 13). The CAD/CAM system technology allows amazing accuracy, pro- viding better functional and economic benefits to patients. The implant prosthesis was made following the CARES approach on the Straumann Variobase abutment, which allows exact engagement of the coping to the Straumann Variobase abutment with its four engaging grooves. For scanning and model- ling of the case, the Dental Wings platform was used to design the implant prosthesis and the ceramic for the adjacent teeth (Figs. 14 & 15). The milling was done in zirconia for later application of ceramic coverage, characterisation and customisation of the elements. The parts were tested in the mouth and, after adjustment, were properly etched and cemented (Figs. 16–21). Final result At four months’ follow-up, the surrounding tissues and occlusion were stable. The patient was satisfied and the radiographic appearance was satisfactory (Figs. 22–25). Conclusion Despite the complications in this case, resulting in the need to activate the implant on the 18th day post- placement, the Bone Level Roxolid SLActive provi - ded a very satisfactory outcome, demonstrating its stability, superior strength and surface treatment, even under extreme circumstances._ about Dr André Callegari is a specialist in dental prosthetics, currently studying for his PhD in Dentistry.
