Bonded lingual retainers have been developed
with various wire sizes, designs, and placement
methods. 1-6 Lew has described a directbonded
lingual retainer made of multistranded
wires in a simple V-loop configuration.2 The
loops extend to the papilla of each retained tooth,
allowing the patient to floss the interproximal
gingival crevices without compromising periodontal
Any bonding technique carries the risk of
moisture contamination, which can lead to bond
failures and subsequently to relapse.7,8 Other
problems with current retainer bonding methods
include the length of chairtime required and the difficulty of precisely adapting the retainer wire
to the lingual surfaces.
The present article proposes a modified
technique for bonding a 3-3 V-shaped lingual retainer,
using a DuraLay* transfer tray as suggested
by Lee and colleagues.7 This time-saving
method allows optimum moisture control and
adaptation while providing the patient with adequate
access for oral hygiene and permitting
physiologic movements of the teeth during retention.

Before removing the fixed appliance, take an
alginate impression of the anterior teeth, and
pour it in hard stone (Fig. 1).
Gently bend the retainer on the cast, following
the contours of the lingual papillae in a “V” or
“U” configuration. An .024" stainless steel wire
will have greater resistance to fracture than
multistranded wires9 and is smoother to the
tongue.10 Extend the wire distally to the first premolars
on both sides (Fig. 2). Apply a separating
medium to the occlusal and lingual surfaces of
the first premolars on the cast.
Form the transfer tray from DuraLay, an
acrylic that is easy to manipulate, requires little
polymerization time, and has good dimensional
stability. Attach each end of the retainer wire to
the cast with DuraLay (Fig. 3). Passive contact
with all the lingual surfaces of the anterior teeth
is critical, because any tension in the wire may
lead to failure.
Cover the areas that will not be bonded—the
V-bends contacting the papillae—with utility
wax (Fig. 4). Sandblast the exposed wire surfaces
with aluminum oxide to improve microretention
and thus prevent bond failures within the adhesive
and at the wire-adhesive interfaces11 (Fig. 5).
Remove the retainer wire and transfer tray
from the cast (Fig. 6).
Prophy the lingual surfaces of the anterior
teeth to be bonded. After etching the enamel and
applying a liquid resin, position the retainer in
the mouth, holding the DuraLay transfer tray in
place with utility wax over the premolar brackets
Cover the lingual surfaces and the sandblasted
portions of the retainer wire with composite
resin, taking care not to invade the papillae or the
interproximal contact points (Fig. 8). For optimum
strength and patient comfort, the composite coverage should be at least 1mm wherever possible.
Once the composite has polymerized, cut the
distal wire extensions at the premolars, being
careful not to damage the enamel. Add composite
to the distal ends of the retainer wire in the
canine regions (Fig. 9).
Remove the brackets and polish the buccal
surfaces of the teeth only after the retainer is
completely stable (Fig. 10). Use dental floss to
check the retainer height and the interproximal
spaces (Fig. 11).
