I 33 case report _ immediate restoration I CAD/CAM 4_2014 Anotherpreconditionforsuccessfultreatmentis a tension-free fit of the prosthetic superstructure. Also desirable is primary splinting of the implants by the superstructure, which can be achieved with a milled bar restoration. Utilising CAD/CAM tech- nology, highly precise wide-span solutions can be manufactured today with an accurate fit. _Case report A 69-year-old female patient presented to our practice. Apart from teeth 17 and 27, her maxilla was edentulous. The remaining teeth could not be permanently preserved due to the periodontal status. A removable temporary denture was an- chored to the maxillary molars. The patient re- quested a fixed restoration to permanently restore masticatory function and aesthetics. The clinical and radiographical examination showed that sufficient bone was available to place implants that would support a fixed restoration (Figs. 1 & 2), and a bar-retained immediate restora- tion on six OsseoSpeed EV implants was planned. The OsseoSpeed EV implants and the new drilling protocol allow for excellent primary stability, which makes this an ideal treatment solution for this particular case. In addition, the OsseoSpeed surface is especially indicated for use in soft bone appli- cations. Fig. 5_Installation of the Uni Abutments EV.
