To close or not close a midline diastema is a very significant issue. Ultimately, such decisions are subjective. The role of the dentist is to help patients understand the various fundamental geometric laws of aesthetics. When the relative balance and harmony of the distributed space are properly proportioned and conform to the laws of nature, either scenario is acceptable. Simple proportions using the Golden Rectangle can be used to help patients assess their individual choice.
