DIAGNOSTIC WORK-UP AND PLANNING CHAIRSIDE DETERMINATION OF INCISAL EDGE POSITION
Comprehensive photographic documentation, both extraoral and The incisal edge position was determined chairside using a direct

Sirona’s Omnicam were obtained. Digital planning (Figure 10) using without tooth preparation.

occlusal relationships, and laboratory communication. • Phonetics (“F” and “V” sounds)
Occlusal assessment confirmed that anterior correction could • Esthetics (incisal display at rest, smile arc consonance)
