1. Set them in contact on the midline. If there is a diastema, set them symmetrically to a vertical midline.

2. Incisal edges on the occlusal plane.

3. Labial surface 8-10mm in front of the center of the incisive papilla.

4. Labial incisal 2/3rds set perpendicular to the occlusal plane.

5. Slight distal inclination. (If you set the incisal edges on the occlusal plane you will automatically have the correct inclination.)

6. Out of contact with lower anteriors.

7. Some overjet, no overbite.

8. Look at the labial surface from the incisal. There should be symmetry. (Of course you can set them in an irregular fashion if the patient chooses.)

9. Should touch the inner third of the lower lip when making the "F" sound.*

10. Should support the upper lip.

(11. Tip to tip relationship in protrusive.)

*When making the "V" sound the centrals touch the middle of the lower lip momentarily, then the mouth is opened. If you set the centrals too long they will hit the middle of the lower lip and then the "F" will sound like a "V." Try saying "leaf" and "leave" to feel the subtle difference.
