Clinical Case: Total-etch Adhesive Bonding of Two Lithium Disilicate Glass Ceramic Crowns
September 30, 2021 | Dr. Rafał Mędzin
About the Case
The female patient was referred because of problematic central incisors restored with old PFM crowns, having insufficient endodontic treatment. Both crowns were removed and after endodontic retreatment and core build-up provisional crowns made of 3M™ Protemp™ Plus Temporization Material were placed. The patient paused the treatment and returned after eight years with the same Protemp Plus crowns. The case was finished with lithium disilicate glass ceramic crowns, cemented with 3M™ RelyX™ Universal Resin Cement and 3M™ Scotchbond™ Universal Plus Adhesive in the total-etch technique.
