Fitted Labial Arch

Orthodontic wire bending
Its name means fitted to the labial aspects of the teeth (incisors). It differs from Hawley arch in
that it is more adapted to the teeth while Hawley arch only touches the labial aspects. This
offers good retention on proclined upper incisors but it is less satisfactory on upright teeth. The
more severe the proclination, the more incisal position of the horizontal arms

FUNCTION
1. Anterior retention.
2. Increase the Anchorage.

USES
It is used in the upper incisor region and rarely used for lower incisors because it is constructed
from 0.7 mm HSSW, i.e. it is considered to be rigid for the lower incisors due to their small
size.

COMPONENTS
1. Small U- loop 2 mm in width and height engaging the embrasure area between two adjacent
teeth (e.g, undercut area between 2 centrals). It should be away from the interdental papilla by
at least 0.5 mm to prevent trauma to it.
2. Two horizontal arches adapted to the labial surfaces of the incisors; at the level of the
junction between the incisal and middle thirds of the incisors.
3. Two small vertical arms extending from the horizontal arms and joining to the retentive arms.
They must pass over the contact areas between the central and lateral incisors to prevent
interference with opposing teeth.
4. Two retentive tags should be adapted in between the two teeth palatally to prevent the
interference with opposing teeth. Then the tags adapt to the palate (rugae area) being about 2
mm away from the palatal midline. They end in a small L-shape (0.5 mm) directed towards the
cast to allow space for the acrylic.
