After wax-up planning, models determined the need of 1 mm increase of occlusal vertical dimension (Figure 3(a)). After impressions of the preparations, composite resins crowns were obtained indirectly by VITA VM LC system (Vita Zahnfabrik, Germany) (Figure 3(b)), due to some clinical difficulties in children with AI, such as to maintain the mouth opening, to apply rubber dam, to control of the humidity, and more time to make the posterior tooth anatomy.
(a) Indirect and direct restorations in posterior and anterior lower teeth. (b) Final rehabilitation demonstrating aesthetic and functional result.
