Fig. 1a: A smile defect of discoloured teeth and presence of a diastema.

Fig. 1b: Four anterior veneers placed to improve smile defects.

Fig. 2: Smile Design Wheel that incorporates patient psychology, health, function and aesthetics.

Fig. 3: Veneer preparations conserve tooth structure compared with full coverage crowns.

Fig. 4: Articulated casts require remounting to ensure minimal spatial distortions at case delivery.

Fig. 5: Articulating paper markings do not measure occlusal force by paper mark appearance, regardless of their depth of colour, mark size or shape. Paper markings cannot determine tooth contact timing sequences either.
