Abstract
Abutment teeth supporting removable partial denture could be faced a number of problems including development of dental caries. If the existing removable partial denture is in clinically acceptable state and the patient does not want to replace the existing removable partial denture, then a new prosthesis for abutment teeth need to be made. The procedure of fabricating a new prosthesis of abutment teeth for existing removable partial denture is complicate and technically challenging. To fabricate the abutment crown, the original cast of patient obtained before any complication to the abutment teeth is required. The original cast should also contain teeth other than the abutment teeth as a reference point. Once the cast is prepared, CAD/CAM could be used to produce retrofitting prosthesis effortlessly and efficiently. This clinical report presents fabricating a crown to fit existing removable partial denture using CAD/CAM for a patient with post and core failure and dislodged prosthesis. The prosthesis had high stability with minimum adjustment yielding satisfying result.
