Functional and aesthetic guidelines for stress-reduced direct posterior composite restorations.

abstract：:The replacement of a restoration is one of the most common procedures in dentistry. However, the criteria for such intervention, excluding catastrophic failure and persistent discomfort and pain, continue to be the subject of considerable debate. The decision-making process remains subjective on the part of the treati...
