Clinical examination revealed an oblique Ellis' and Davey's Class II fracture of the maxillary left central incisor and less than 1 mm of overjet and overbite between the arches [Figure 1a]. A three-dimensional reconstruction of the preparation was done using the CEREC InLab 3D software 3.03 (Sirona Dental Systems Inc, New York, USA) providing for a 1-mm reduction of the milled prosthesis on the labial surface and incisal third of palatal surface [Figure 1c] for veneering ceramics. The cemented restoration was evaluated clinically [Figure 1d] and radiographically [Figure 1e] and appeared to give good esthetic and functional results.
