/ Clinical Cases / Indirect Posterior Restorations: different materials, different finishing lines, one cement.
April 18, 2022
Using 3M™ Scotchbond™ Universal Plus Adhesive and 3M™ RelyX™ Universal Resin. Cement
Posterior restorations are challenging: many different materials can be used, direct or indirect. In this clinical case, a young patient had a debonded crown on second upper premolar and two failed restorations in first upper molar and first upper premolar. When we face multiple restoration, indirect approach should be considered. Adhesive partial restorations were made of lithium disilicate and crown of full-contour zirconia. Different materials, different indications but only one cement for all was used.
