Titanium interface to use zirconia abutments

The use of zirconia abutments enables to significantly improve the aesthetic result of restorations on implant, but establishes in the long term a risk of deformation for the connection (subsidence of the internal connection and loss of the airtightness,...) under the influence of repeated masticatory constraints. It is thus necessary to keep a titanium interface between the implant connection and the prosthetic element, the smallest possible, which will be the base to achieve the zirconium abutment.
