A dentist treated a patient with an endo-treated first molar and failed second molar. Two CAD-CAM onlays were prescribed with Griptabs attached to aid cementation. The onlays were prepared, ultrasonically cleaned, etched, silanated and cemented with Wave-Wedges to control cement flow and prevent tissue trauma. Post-cementation, the Griptabs and Wave-Wedges were removed, leaving the successfully cemented onlays in place.
