February 8, 2022 | Dr. Akit Patel
About the Case
A 68 year old patient presented with severe wear on tooth 36. The tooth was conservatively prepared for a non-precious metal adhesive onlay to protect the exposed dentin and restore occlusal function. The onlay was pre-treated by sandblasting and in this case the optional priming of metal with 3M™ Scotchbond™ Universal Plus Adhesive was done. For the cementation 3M™ RelyX™ Universal Resin Cement and Scotchbond Universal Plus Adhesive were used in the selective-etch adhesive technique.
