A technique for assessing the fit of a removable partial denture framework on the patient and on the definitive cast.

The lack of fit of a removable partial denture has been reported as the most common problem in the treatment of patients with partial edentulism. The misfit could be a result of poor laboratory procedures, a distorted impression, or ridge remodeling after delivery. Evaluating the fit of a removable partial denture starts at the framework evaluation appointment. The evaluation consists of the fit on the definitive cast and the fit intraorally. Damage to the definitive cast by inserting and removing the framework must be avoided, and the components of the framework should fit well on the cast before it is placed intraorally. Clinicians usually use components, such as rests and lingual plates which have contacts with the teeth as references for the fit evaluation. Disclosing media, including disclosing paste (PIP; Keystone Inc) and aerosol-disclosing indicator (Occlude; Pascal Inc), could be used to evaluate the fit of the framework; however, the minor connector in the edentulous area is seldom evaluated clinically because it
