Key challenges
* Teeth severely damaged because of the fall
* Patient doesn’t want extraction (especially the most severe damaged #12)
* Patient wants to have esthetic result but with minimally invasive preparation (used Porcelain Laminate Veneer)

Discussion
All-ceramic solutions are better for this particular patient because of esthetic and natural results. In particular, PLV (Porcelain Laminate Veneer) provides minimal intervention and good esthetic characteristics.

However, they are not retained with a mechanical structure. It is essential to apply a high-performance dental adhesive between porcelain restoration and the tooth side. Esthetic results stand on the “Function, Structure and Biology” concept.

Esthetic Dentistry stands on the “Function, Structure, Biology” concept like a house. When we build a house, we have to check the land condition. Even when we build the esthetic house, it may collapse if the land condition was not so good.
