Clinical Cases / Total-etch adhesive cementation of a zirconia Maryland bridge
/October 13, 2025
Using 3M™ Scotchbond™ Universal Plus Adhesive, 3M™ Filtek™ Universal Restorative.
A 27-year-old patient with a congenitally missing tooth 22 received orthodontic treatment for three years, however no sufficient space for placing an implant was achieved, due to root proximity (wagonwheel effect). Treatment plan decision was to place a resin bonded uni-wing Maryland bridge. After extraction of the persistent deciduous lateral incisor, pontic site development was performed with the help of a removable retainer. A very shallow preparation of the palatal surface of the left central incisor with a small positioning groove was performed. A labially veneered zirconia bridge was fabricated and bonded with 3M™ RelyX™ Universal Resin Cement and 3M™ Scotchbond™ Universal Plus Adhesive following a total-etch adhesive protocol.
