The determinants of success in fixed prosthodontics are adequate tooth preparation and the maintenance of parallelism of abutment teeth, particularly in the case of fixed restorations involving multiple missing teeth. Such preparation helps provide an acceptable interim restoration and bioesthetic final prosthesis. The application of a putty or vacuum-formed guide for the assessment of the amount of tooth reduction and provisional fabrication in the case of single or multiple teeth preparation is a widely followed technique. However, its application in the case of multiple missing teeth scenarios is yet to be accomplished.The purpose of this technique is to fabricate a single vacuum-formed matrix that will help access the parallelism of multiple prepared abutments, assess the amount of reduction, facilitate provisional fabrication, and serve as a guide for the final wax-up of the restoration. A necessary mock wax-up is done on the diagnostic cast. A clear, vacuum-formed resin matrix is formed on the cast, which is utilized for the assessment of tooth preparation, fabrication of interim restoration, and evaluation of wax coping for the final restoration.In this novel technique, a single vacuum-formed matrix is utilized for assessment and to aid in various steps involving the successful restoration of a scenario with multiple missing teeth.
