CONELOG Special Issue

Case Report 16 | 2013 Fig. 26: Optimal hold of the wax-up during try-in through filled implant interface. Fig. 25: The periimplant emergence profile was expanded and the papillae sharpened to provide a harmonious gingival profile. Fig. 28: The Esthomic abutment, extended with a bonding aid, shows the palatal positioning of the access channel. Fabrication of primary and secondary abutments Fig. 29: Customizing the primary abutment ensures suf- ficient coating strength of the zirconium oxide abut- ment. Fig. 30: The titanium base and the completed model of the secondary abutment are scanned in the laboratory. Buccal space is left for the planned pressed ceramic veneer. Fig. 27: Overview of abutment options: (from left): CONELOG ® Esthomic abutment (gingival height 1.5–2.5 mm) prior to and after customizing, CONELOG ® Titanium base CAD/CAM. Fig. 23: The precise periodontal and periimplant soft-tissue situation is represented on the master model. Fig. 22: Preparation of the master model. The wax pins serve as access to the stumps on the master model. Fig. 24: The marginal border of the planned implant crown is transferred to the plaster surface. Fig. 21: Individual stumps made of super-hard plaster with grooves to protect against rotation are fixed in the impression with instant adhesive. Model preparation and functional wax-up After a three-month healing period, the periim- plant and periodontal tissues are ready for final impression-taking. The healing cap is unscrewed and a CONELOG ® Impression post for open trays screwed in. Impression-taking is performed in one step with an open individual tray and a two- phase polyvinyl siloxane (A-silicone). In this case, the CONELOG ® Titanium bases CAD/ CAMare too low due to the apical position of the implant shoulder. Therefore, the dental tech- nician decides on a considerably longer, straight CONELOG ® Esthomic abutment, which is customized for use as a titanium bonding base. Subsequent bonding of the primary and second- ary abutments results in a hybrid abutment with full anatomical contours.
