Canine rests

When the mesial marginal ridge of the first premolar is too close the fulcrum line or when there is not enough interocclusal space in that area, lingual or cingulum rests are positioned on the adjacent canine (Figure 4-5). The minor connector can be positioned in the embrasure anterior to the canine, either curving back onto a prepared lingual rest seat, or both, to increase the effectiveness of such a rest.
