Multi-Unit Abutment: Why, Where, When?

Dental implants are a well-documented intervention for both partial and complete edentulism.As the success of dental implant osteointegration led to its widespread and predictable use in dentistry, the need to address challenges with certain prosthetic components has emerged to meet technical and anatomical demands.One key concept is the importance of a passive fit.The implementation of a multi-unit abutment system offers a viable solution for fabricating screw-retained, implant-supported prosthetic structures with a passive fit by providing a short cone external connection.Multi-unit abutments serve as connectors between dental implants and screw-retained restorations, especially when correction of the implant's three-dimensional position is necessary.
