Case Description: With this case, I took a conservative approach to preserving tooth structure using an overlay bonding restoration. A 42-year-old female patient came to my of?ce after receiving root canal treatment. Once the tooth was treated, cuspids were preserved to avoid possible fracture of the remaining structure. Cusps were prepped by reduction of 1 mm at the occlusal surface, a VPS impression was taken, and the dental laboratory milled a lithium disilicate overlay (occlusal veneer).
A rubber dam was placed, and the enamel surface was etched with phosphoric acid, rinsed with air/water, and the surface was gently dried. Two consecutive coats of All-Bond Universal
were applied and rubbed. The solvent was then evaporated with air and light curing was performed.
For the bonding stage, eCEMENT
dual cured resin cement was applied on the intaglio of the restoration. The restoration was delivered over the tooth surface, with gentle pressure applied, tack cured, then cleaned and flossed. Each tooth was light-cured. Glycerine gel was applied and light-cured. The rubber dam was removed and the restoration polished.
