Ensuring passivity and retrievability for immediate complete-arch implant-supported prostheses

This technique describes the fabrication of frameworks for immediate complete-arch implant supported prostheses to ensure that the dimensional alterations that occur during the casting procedure do not interfere with passivity. As sectioning and soldering are not necessary, there is no delay in the fabrication process, and the framework is not weakened. Titanium abutments for interim screw-retained prostheses are prepared on the definitive cast, and framework waxing preserves the access holes to the screws. After casting, the framework is cemented on the prepared abutments. The proposed technique has been created to combine the advantages of cement-retained frameworks and the retrievability of screw-retained ones.
