Clinical Case: Post Reinforced Core Build-up

Featuring new 3M™ RelyX™ Universal Resin Cement and new 3M™ Scotchbond™ Universal Plus Adhesive.

About the Case

The 47-year-old female patient presented with a heavily destroyed tooth 15 and the strong wish to keep the tooth by any means. Key step of the planned approach was the magnetic extrusion of the root after root canal treatment. After core build-up with a post, a full-contour zirconia crown was placed. 3M™ RelyX™ Universal Resin Cement was used for self-adhesive cementation of both the 3M™ RelyX™ Fiber Post 3D and the 3M™ Lava™ Esthetic Full-Contour Zirconia Crown. 3M™ Scotchbond™ Universal Plus Adhesive and 3M™ Filtek™ One Bulk Fill Restorative were employed for the core build-up.
