2 3 PRODUCTS PRODUCTS THE COMFOUR TM SYSTEM VERSATILE AND COMFORTABLE FOR BOTH USER AND PATIENT the cam alignment during implantation. The aligning tools are compatible with the CAMLOG Guide System and are inserted using the Guide insertion posts for precise alignment of the inner implant configuration. The scan caps for bar abutments create an inter- face in digital fabrication. They allow the position of the bar abutments and the lab analogs to be digitalized, thus enabling the fabrication of frame- works and bars using DEDICAM ® . Sterile and flexible To ensure that the handling of the components in the COMFOUR ™ System is as simple as possible, a critical change was made to the previously familiar bar abutment system. All components used during surgery are packaged sterile. This means that there is no need to sterilize the bar abutments, healing caps for bar abutments, the impression caps for bar abutments, and closed trays before use. The insertion of the angled bar abutments is simplified by an ingenious flexible handle that is used as an insertion aid. The handle is fixed in the thread of the prosthetic screw and holds the bar abutment in place. In order to screw the abutment screw that is already located in the bar abutment into the implant, the handle can be simply bent to one side. Particularly when the vertical space available is limited, this greatly facilitates the procedure (see page 15). If impression taking with the open tray technique is indicated, the titanium caps for bar abutments are mounted and combined with screws of three different lengths, each of which can be shortened by 2.5 mm. New light blue screws The familiar bar abutment components such as the burn-out, laser-weldable, solderable, and cast-on bases are fully compatible with the COMFOUR ™ System. Only the abutment and prosthetic screws have been modified. All screws and screw- retained components are color-coded light blue for easy identification. An immediate, comfortable solution The new COMFOUR ™ Abutment System enables per- manent, occlusal screw-retained restorations and satisfies patient desires for an immediate, com- fortable, and permanent denture. COMFOUR ™ saves time during use and offers clinicians and dental technicians greater flexibility for occlu- sal screw-retained designs. With its options for bar and single-tooth restorations, COMFOUR ™ extends the prosthetic options available at bar abutment level and has a number of impressive technical advantages such as its anti-rotation mechanism, a pre-mounted flexible handle, the aligning tool which is compatible with the Guide, and an extremely slim design. The aim of the COMFOUR ® development was to market a system for occlusal screw-retained treatment concepts that provided value-added advantages to both users and patients. After detailed analysis, the development team and product management at CAMLOG decided to develop the new abutment system for occlusal screw retention on the basis of the former bar abutments.The range of bar abutments was greatly expanded and modified, and the collaboration with experienced clinicians enabled the creation of the new COMFOUR ™ Abutment System. Slender and stable New machinery was specifically purchased for the production. This enables the angled bar abutments to be designed to be as slender as possible, which leaves plenty of room around the abutment for the hard and soft tissues. Presuming sufficient primary stability of the implant, the sterile bar abutments can be immediately insert- ed after surgery and fitted with the temporary restoration. Alternatively, the bar abutments can be sealed with a healing cap. All other treatment steps such as impression taking and the definitive restoration are done at abutment level. This avoids irritating the gingival cuff as a result of repeatedly detaching the soft tissue attachment during insertion and removal of the abutment. The COMFOUR ™ System provides clinicians with a modern, easy to handle abutment system not only for restorations on four or six implants, but one that also comes with a range of options to meet the challenges of routine clinical practice. The refinement of the tried and tested bar abutments is welcome. A comparison with current comparable systems offered by competitors shows that the prosthetic screws of the COMFOUR ™ System (M1.6) have greater dimensions – for greater stability. Comprehensive range of abutments Alongwith straight bar abutments, theCOMFOUR ™ System also includes 17° and 30° angled bar abutments. These are available as type A and type B (60° offset cam arrangement). All bar abutments are available in two gingival heights; straight bar abutments from a diameter of 3.8 mm are even available in three gingival heights. Useful additional components are the titanium caps for bar abutments for both tempo- rary and definitive restorations as well as the aligning tools for making fine adjustments to Occlusal screw retention is a state-of-the-art treatment method. COMFOUR ™ equally enables several different treatment concepts. It is a multi- option system that permits bar and single-tooth restorations for straight and angled bar abutments in addition to screw-retained bridges for immediate and delayed restorations. The COMFOUR ™ System is available for the CAMLOG ® and for the CONELOG ® Implant Systems. The major advantages of the new abutment system are its versatility and the product design, combined with safety and a high level of comfort for user and patient.
