Prosthodontic Management of Malpositioned Implants in Anterior Maxillary Region : A Case Series

Three cases of prosthodontic management of malpositioned implants have been reported. Case I presented with a severe faciopalatal and a deep apicocoronal position of the implant. Definitive restoration was planned using a UCLA type plastic abutment to fabricate a framework over which a cementable coping was made. Case II presented with severe faciopalatal angulation of the implant. The definitive prosthesis was fabricated using a custom cast abutment. Direct Ceramic build up was done over the abutment and it was attached to the fixture with the abutment screw. Case III also reported with severe labial angulation of both the implants and definitive restoration was done with the help of UCLA type plastic abutment to design a customized framework for the definitive prosthesis. Soft tissue management for all the three cases was done with the use of gingival porcelain on the cervical portion of the metal-ceramic restoration. The use of customized and UCLA abutments presents an easy and cost effective way of functional and esthetic rehabilitation of malpositioned implants.
