arch“

wire brackets on the lingual, has shown that
there are many ways to achieve excellent
lingual results.

5. Initial Brackets
An .018" slot size conservation of incisal-ingival bracket
dimension and for compatibility with existing archwires
Modification was made in the bite plane on the maxillary
cuspids, from a flat plane to a bi-beveled plane, in order
to minimize bracket-cuspid interference in the final Class
I cuspid relationship
The Lingual Task Force was established in December
1980 to provide additional input on design
considerations and to expand the treatment modalities.
Ball hooks were added to all lingual brackets at this time.
Ball hooks, while aiding greatly in placing elastic
ligatures and elastics (Fig. 8), can cause gingival
hyperplasia

6. Later Modifications
Maxillary anterior brackets incorporate a bite
plane designed into the incisal edge of the
bracket (Fig. 2). The bite plane is parallel to the
archwire and the occlusal plane.
All brackets have a gingival ball hook which
greatly facilitates elastic ligature placement,
rotation control, and placement of intra- and
intermaxillary elastics

7. Patient selection
. Maxillary incisor lingual crown heights of less
than 6mm will not permit sufficient space for
bonding the brackets to avoid gingival
impingement and still finish with 1 to 2mm of
overbite.
