Risk versus gain in the flapless immediate approach for anterior implant esthetics: case reports.

The esthetic success of anterior implant therapy still depends primarily on the degree to which natural soft tissue harmony can be preserved or reestablished. Many techniques have been described to preserve or augment the contour and volume of soft and hard tissues, particularly in the anterior maxillary zone. The level of predictability, however, remains variable. This article describes some clinical observations that may increase predictability in selected cases.
