At times it is necessary to make or remake a crown for the abutment under the clasp of an existing removable partial dentures (RPDs). The problems are usually compounded by the patient’s refusal to relinquish the denture for the time needed to fabricate the restoration and the difficulties involved in the procedures in making any details of crown to fit with the existing RPDs. A review of the literature discloses a number of different methods in solving the addressed problems. Some techniques are only partly indirect and require extensive chair time. Some are directly done in oral or some may need both. The details, also the advantages, disadvantages in each technique are described in order to be the information for the dentists in choosing the proper and the effective method for the patients.
