Restoration of partially edentulous patients using customized implant abutments.

The ideal placement of implants is not always possible in partially edentulous patients. The diverse and unique implant positions that occur in clinical practice may be difficult or impossible to restore through the use of conventional abutments. Customized abutments permit the fabrication of aesthetic restorations that correct deficiencies in implant angulation, alignment, and position. These abutments also enhance the soft tissue emergence profile of the restorations and allow the prosthetic margins to be properly positioned in all dimensions. Additional benefits include ease of treatment delivery and comparative expense.
