This is a review of the literature of the last 21 years about cementing or luting indirect restorations to tooth structure. Recommendations are made as to the surface preparation of precious metals, non-precious metals, indirect composite materials, and all available porcelain materials including feldspathic, luecite reinforced, lithium di-silicate, slip cast aluminum oxide, densely sintered aluminum oxide, and zirconia prior to luting. Using data from a variety of sources, product categories of materials and various bonding materials and procedures are ranked according to their bond strength and durability.
