32 I I industry report _ navigated implant placement mising the post-operative consequences such as pain, swelling and the formation of haematomas. Moreover, it allowed the impression for prepara- tion of the master model over teeth and implants tobetakeninthesamesurgicalsession(Fig.5).The dental laboratory contributed to the production of the X-ray templates early in the planning phase, was familiarised with the case and involved in the discussion about the desired implant positions. The benefits for the patient included a safe opera- tion,sincethesurgeonplannedtheentireoperation beforehandandthusexpectedapredictableresult. A difficulty in the present case was the relatively soft quality of the bone. Under these circum- stances, NobelActive is beneficial for the experi- enced surgeon since it rotates into the bone much like a compression screw, which allows good pri- mary stability to be attained. TheNobelActiveimplant The TiUnite surface of NobelActive implants affords osseointegration down to the level of the implant shoulder rather than to just below the implant shoulder owing to the biological width of at least 1 mm as is customary for conventional implants. This is associated with significant advan- tagesfortheaestheticsofthered–whitetransition. The gingiva is more stabile and resection is less pronounced, which leads to the volume being maintained. This effect is of crucial importance for the success of an implant treatment in the anterior region, where aesthetic appearance is extremely significant.

The available framework materials for this purpose are zirconium-oxide ceramics and tita- nium. Titanium was selected in the present case (Figs. 6 & 7). Additional advantages of this technique are: _screw-retained abutment and bridge (Fig. 8); _tension-free framework; _bridge construction and implant are made of the same material; Figs. 13a–n_Treatment plan.
