'Biological restoration': total crown anterior.

Restorative odontology is in constant evolution and is constantly seeking more aesthetic solutions to attend to demands from patients in search of the perfect smile. The case study presented herein refers to the aesthetic and functional recuperation of dental element 21, through the use of a dental fragment obtained through an extracted tooth, a technique known as 'Biological Restoration'. The results obtained, which were highly satisfactory, lead one to conclude that this technique can be considered as an alternative to all others and can be carried out successfully, quickly, and inexpensively.
