Modification of Existing Fixed Metallo-ceramic Screw Retained Implant Prostheses to Improve the Esthetics: a Case Report.
J Pak Dent Assoc Jan ;25(1):38-40.

The success in implant dentistry in esthetic zone is determined by the inconspicuous results obtained with the final prosthesis1 . This can be achieved with quite certainty in partially edentulous patients by obtaining direction from the adjacent dentition and manipulating the soft tissue for better emergence profile2 . However, obtaining better outcome is troublesome in completely edentulous patients in which pattern of alveolar bone loss in particular affects inter arch relationship and other associated morphological changes. Thus, final prosthesis not only warrants restoration of missing teeth but also additional support for the lips to compensate for the severe hard and soft tissue loss. This can be achieved with the appropriate planning, placement and inclination of implants according to the planned prosthesis but this is not always true as position and inclination of implants might differ due to various surgical and anatomical factors resulting in reevaluation of the planned prosthesis after implant placement3 . At times, the decision for final prosthesis needs to be reconsidered even after delivery of the final prosthesis; this is due to differences in outcome and expectations.
