Luting Procedures
"The structural integrity of the intact tooth has been explained in port by the structure/ property relationship at the dentinoenamel junction [DEJ). Enamel and dentin alone do not have outstanding mechanical properties. Nevertheless, when assembled at the DEJ, they have a unique structure that can ensure optimal function and stress transfer for a lifetime. The same statement can be claimed for bonded porcelain restorations, and the DEJ sets the reference for the ceramic-composite-tooth restorative complex. "
Immediate Dentin Sealing
Immediate dentin sealing (IDS) is the application of a bonding agent to freshly cut dentin when preforming a preparation for an indirect restoration such as inlay/onlays and crowns. Some of the advantages of the procedure are: effective seal of dentin, increased adhesion, reduced postoperative sensitivity, all of this while creating a hybrid layer that mimics the existing dentino-enamel junction. This hybrid layer also prevents the collagen from collapsing during impression taking and the final bonding process. The layer also reduces shrinkage stresses which in turn helps to promote a stress free dentin bond development. IDS is an advanced protocol aimed to increase the success rate of preparation, temporization, and final bonding of indirect restorative procedures. There is a great amount of research being done on the properties of dentin bonding. This is an emerging area of biomimetics that is truly having great results coming from it. Procedures like these are what is allowing biomimetic dentistry to take shape.
