The effect of a titanium socket with a zirconia abutment on screw loosening after thermocycling in an internally connected implant: a preliminary study

Since esthetic demands of patients increase, it has been accepted to attempt to use zirconia for fabricating prosthetics because of the mechanical properties. However, when choosing abutments for the posterior implant region, zirconia material was not preferred to overcome titanium material. When especially using internally connected zirconia abutments, connection area between the implant and the abutment might be weak to fracture. Because of the weak link between the zirconia abutment and the titanium implant, especially in internal type systems, dentists have been somewhat afraid of using zirconia abutments in the posterior implant region. The introduction of zirconia abutments with a secondary component for internally connected implants was one of major breakthrough endeavors to overcome this weak joint in the zirconia abutment and the implant connections.
