Introduction: For the making of individual milled or cast dental treatments pure titanium is increasingly proved regarding technical and clinical aspects. Nearly all restaurative indications can be covered by using titanium. Because of comparatively unfavourable mechanical values (low 0.2% yield strength, low elastic modulus, low fatigue strength) cast RPDs made of pure titanium are still critically discussed and their metal frameworks have to be stronger dimensioned. The usage of titanium alloys offer new aspects. Due to their advantageous elastic properties by concurrent high mechanical strength titanium alloys seem to be more suitable for making cast RPDs. Objectives: TiAl6Nb7 is examined regarding their usage for cast prosthodontic treatments. Therefore on one hand capability of moldfilling, elastic behaviour and weldability and on the other first clinical surveillances are presented. Material and Methods: Two different titanium alloys (TiAl6V4 and TiAl6Nb7) are cast and analysed by the so called outflow test regarding to Meyer. The elastic behaviour is tested using a static bending test of clasp-profiles made of pure titanium, a cobalt-based alloy and titanium alloy (TiAl6Nb7). Therefore values of maximum deflection and appendant force are taken. A first probational welding is done to verify the joining of pure titanium and titanium alloy and in-between titanium alloy. Results: Even though a high viscosity of its melting, TiAl6Nb7 shows a good castability. The elastic behaviour of the titanium alloy shows a good proportion of elastic plasticity and rigidity that is important for designing cast RPD's. Welding of titanium alloys is possible but further examinations have to be done. Conclusions: The titanium alloy TiAl6Nb7 can be recommended for clinical appliance and is an option for conventional model cast alloys. Schlagwörter: Titanlegierung
