Base for an orthodontic appliance includes a base surface adapted to be attached to a tooth and a plurality of protrusions protruding from the base surface and extending along a first direction substantially from a first edge of the base surface to a second edge of the base surface, a second direction being defined as perpendicular to the base surface, wherein the distance between two of the protrusions in a plane substantially perpendicular to the first direction along at least a portion of the protrusions is smaller than the distance between the two protrusions at the base surface, and wherein the distance between two of the protrusions in planes substantially perpendicular to the second direction at the first edge and the second edge is larger than a distance between the two protrusions in a plane between the first and the second edge.
