Mechanical behavior of a bi-layer glass ionomer
Abstract Objective A high-viscosity consistency of the glass-ionomer cement (GIC) may lead to poor adaptation into the cavity. The use of a flowable GIC layer seemed to improve its adaptation…
Cyclic fatigue testing of denture teeth for bulk fracture
Abstract Objectives Clinical experience with implant-supported dentures indicates that fracture and chipping of teeth are becoming an issue. Tooth fracture and chipping rates of approximately 2.5% per year are being…
Strategies to prevent hydrolytic degradation of the hybrid layer—A review
Abstract Objective Endogenous dentin collagenolytic enzymes, matrix metalloproteinases (MMPs) and cysteine cathepsins, are responsible for the time-dependent hydrolysis of collagen matrix of hybrid layers. As collagen matrix integrity is essential…
