DEFINITION OF ROLLED EDGE RESTORATION:
It is defined as long-standing attrition, often against an upper denture, where the enamel periphery is rolled or radiused, so that it cannot be mechanically instrumented into a fresh-cut rod-end internal margin, nor is a bevel perfectly attainable. It also seems unconservative to cut the incisal edge down a millimeter in order to establish an incisal shoe. Thus It represents a compromise restoration where enamel axiom #1, enamel axiom #2, and enamel axiom #3 cannot be perfectly met . However, satisfactory clinical life and effective bonding are attained by sandblasting with 27or 50–micron aluminum oxide and preparing into dentin to create retention form in the dentin, like the incipient incisal restoration.
If the restoration were to be separated from the tooth, it would resemble a trumpet in cross-section . The very thin perimeter is subject to chipping. However, treating the sextant slows down wear, improves esthetics ,and prevents enamel edge fractures.
My experience in placing well -etched, well-bonded, heated resin has been positive. 5-years without significant breakdown is easily attainable. Note the sclerotic dentin in the photo below; sandblasting is indicated to increase surface area and increase adhesion. This is not as retentive as intratubular dentin bonding but certainly better than un-abraded dentin.
