Clinical Evaluation of a New Dual-cure Universal Adhesive

November 2, 2026 updated by: Ivoclar Vivadent AG

Clinical Evaluation of a New Dual-cure Universal Adhesive for Indirect Restorative Treatment

The overall aim of this study is to evaluate the clinical performance and safety of the new dental dual-cure adhesive for luting indirect ceramic restorations (inlays and onlays). The primary aim is to determine the rate of postoperative hypersensitivity occurrence after using the new adhesive for the placement of indirect restorations. The secondary objective of this study is to assess the long-term clinical performance of the new adhesive in terms of marginal quality, retention/fracture rate of the ceramic restorations, and vitality/fracture rate of the restored teeth.
