Although resin-based composites have been used to restore posterior teeth
since the early 1970s,1–4 the posterior composite technique has not been
fully accepted in our profession. Recent advances in polymer chemistry
and light-initiated polymerization systems have improved adhesives, composites,
and light-curing, but concerns with composite wear, less than ideal
bonding to dentin, polymerization shrinkage and related stresses, postoperative
sensitivity, cost, and technique sensitivity still exist.
