In terms of clinical technology, the various pure prostheses complicated settings skeleton is characterized by the wide range of clinical situations resolve these types of restaurants complicated settings. Skeletal mobilizable prostheses, by the possibility of their construction, are resistant prosthetic substitutes, with efficient possibilities of static and dynamic balancing and, very importantly, with the ability to physiologically transfer to oral biological structures a large amount of stress through the remaining teeth included in the prosthesis support perimeteThe aim of the study is to identify the causes of technical and clinical technological deficiencies in the performing of partially mobilizable skeletal prostheses, with the exact placement of the moment when it occurred and the tracing of the main landmarks in their avoidance. The factual material was represented by the evaluation of a number of 45 removable prostheses, which within 5 years from their elaboration presented a series of deficiencies, consequences of non-compliance with the strictly technical elements or found in clinical stages with implications on success or failure on a long term. On top of that, mastication affects the clasps by bending them and having a special importance in producing wear. If the wear is not observed at the level of the maximum convexity of the tooth, it can be evaluated that the fracture due to the wear of the metal in the case of inactive cobalt-chromium clasps can occur after approximately 7 years of use. Cobalt-chromium alloys can be used as metal alloys for partially removable dentures
