I 09 special _ composites I cosmeticdentistry 4_2013 conditions such as minor aesthetic form and colour corrections or extensive de- cays in non-vital teeth, lead to evident solutions (direct and respectively indirect restorations), while the majority of other cases lie in a “gray zone” which actually makes a pertinent choice more intricate. A simple yet effective approach to this dilemma relies on a sound bio-mechanical analysis of the teeth potentially involved in the treatment status, combined to the usual functional and aesthetic analysis. Then, having as a prime objective the re- spect of tooth biology and conservation guidescliniciantoalogicaldecisionaltree, such as presented in table I. The “Bio-aesthetic” philosophy actual- ly give priority to chemical color improve- ments (vital bleaching, non-vital bleaching, micro-abrasion), associated to direct composite restorations and bonded ceramic restorations for more extensive decays, limiting the use of traditional full crowns to existing restoration replacement and a few conditions of extreme tooth “fragilization” (weakening). The progres- sive treatment concept presented in table II then summarizes the modern vision of aesthetic restorative dentistry.
