The Journal Impressions and bite registration in centric relation was recorded (image 8). Treatment plan The patient was explained about the present situation of porcelain fracture and multiple carious teeth. Also biomechanical aspect of the prosthesis was discussed with the patient for a long term treatment success. The treatment options like fixed partial denture were not feasible biomechanically unless supported by implants. But the financial constraints let the patient decline the implant supported prosthesis. The removable cast partial denture was then agreed upon by the patient and the following treatment plan was thus formulated and executed. Removal of the earlier fixed prosthesis was done (Image 2). Oral prophylaxis was carried out, restorative procedures of the carious teeth was performed, followed by endodontic treatment of 18, 13, 21, 22 and 26. New diagnostic casts were made and surveyed for planning cast partial denture. The teeth required for engaging cast partial denture components were surveyed for undercut locations and depth with the help of dental surveyor. Full veneer crowns restoring the compromised abutment teeth and correcting crown contours and occlusal plane were decided. Shade selection, crown preparation for 18, 13, 21, 22, 26, 28 were done. Provisional restorations were given (Image 5). Image 8 Wax pattern of crowns were surveyed for fulfilling requirement of path of insertion of planned prosthesis. Try-in of posterior metal and anterior metal-ceramic crowns was done (image 6, 7) followed by cementation after minor adjustments and polishing.
