Pre-operative initial situation. Lateral (a) and frontal (b) view of a 32-year-old female patient, in good systemic health, presented with an advanced chronic periodontitis, teeth mobility and recurrent infections, persisting over years. In the upper jaw, in particular, all teeth were sensitive and elongated and this seriously compromised the function and the aesthetic of the smile. The patient suffered from this situation and she was strongly motivated to solve this biological, functional and aesthetic problem. c Frontal and (d, e) lateral intraoral pictures. f Panoramic radiograph. In the maxilla, the severe chronic periodontitis determined an advanced bone loss, that compromised the stability of all teeth. g Upper and (h) lower jaw precision models
