• Before we can get there, we need to understand the SPEED basics

3. The SPEED Appliance - 1980
• Invented: Dr. G.H. Hanson. Manufactured: Aerospace
Manufacturer Strite Industries.
• Introduced to market in 1980 after 5 years of clinical
development and 400 completed treatments.
• Highly flexible outer wall (Spring-Clip) capable of deflecting in all
three spatial planes when contacted by the archwire.
• The first S-L design to provide the combined benefits of low
friction, and the essential component of exceptional tooth
control.
• The 1st commercially successful Self-Ligating appliance.

4. SPEED’s Unique Mode of Action
A New Paradigm - Exceptional Control
Rotation Tip Torque
• SPEED’s Spring-Clip stores energy once deflected by the archwire.
• Gradual release of this stored energy ! corrective tooth movement in all three planes of space.
• Unprecedented level of control + Constant corrective action that will not degrade over time (unlike traditional
ligatures).
• Elimination of elastomeric ties reduces frictional resistance by as much as 90% (Berger AJODO, 1990).

• Small window in Spring-Clip ! accept the tip of a SPEED opening instrument or generic
scaler.
• Dramatically increased the simplicity and speed of opening the appliance.
• Archwire changes 4x faster than traditionally ligated appliances.*

• Clip is 400% more elastic than
Stainless Steel
! Resilient Spring Clip entraps the
wire
• Spring Clip and archwire cooperate

24. How does the SPEED Appliance Differ?
• Choosing Between
Choosing between low friction or full control
Low Friction or Full
Control
Undersized wire Full sized wire
Low friction - Poor control Full control - High friction

25. How does the SPEED Appliance Differ?

26. Better torque control
• Active spring clip seat the wire into the slot
• Passive clip can't seat the wire unless filling
the slot
! Therefore, torque is dependant of the wire play and
the torsional moment (N-mm) created by its Torque play: ± 5° for .020 x .025 wire in .022 slot
relationship to the bracket slot
! Torsional moment is related to wire stiffness in
torsion " Bigger wire = Bigger moment
! Use of pretorqued wire is an implicit admission that
the bracket can’t achieve torque Torque play: ± 10,5° for .019 x .025 wire in .022 slot

28. Why my patients prefer
SPEED brackets?
• The smallest bracket on the market = SPEED
©Dr Sylvain Chamberland
29. Proposed Core Advantages of Self-Ligating brackets
Eliasdes T., Pandis N., Self-Ligation in Orthodontics,2009, Wiley-Blackewell
• Faster ligation = Less chair time
! Save up to 10 minutes for replacement of a wire
• Ligation stability - Secure archwire engagement
• Low friction??
! Ligature ties and elastomeric ties may cause friction
! Resistance to slide if affected by bending and notching
! Passive zone = low friction
! Active zone = higher friction
©Dr Sylvain Chamberland
30. Proposed Core Advantages of Self-Ligating brackets
• Practice builder
! Promote the smallest SLB = SPEED
• Assistance to good oral hygiene??
• More comfortable treatment??
! Initial .016 Supercable wire will more likely cause less pain
than a solid .016 niti wire
! Differences in design of SLB have important consequences
! SmartClip: marked increase discomfort when removing and engaging wire
! Damon2: low discomfort initially, but higher discomfort at later stage
©Dr Sylvain Chamberland
31. Benefits of a Self-Ligating Bracket System for a
Patient
• Minimal initial discomfort
! Light, continuous forces if used with Supercable™
• Better oral hygiene, minimal tissue lacerations, if any
• Shorter office visits !less chair time
• Longer interval between visits
©Dr Sylvain Chamberland
32. Do you think self ligating brackets will replace
conventional brackets in the future?
• "In the near future, yes, they will, to some degree, replace
conventional brackets." ... "I am extremely surprised to see
that ligation brackets are still so much in use. Clinical
advantages of the self-ligating brackets are not limited to
saving chairside time; they also produce less wire-to-bracket
friction, require less stock in the practice and if used
efficiently they may increased the practice production by
15% to 30%."

34. Self-ligating bracket claims
Ask us, AJODO 2010, 138, #2, 128-131
• SLB more efficient and more effective than conventional
edgwise bracket systems in treating malocclusion
! Current evidence does not indicate differences for treatment time, rate
of alignment, rate of space closure, final arch dimension or occlusal
outcomes
! Neither for : reduced friction between archwire and bracket, reduced
clinical forces, patient pain, more hygienic

46. Control - Spring Clip Resiliency
• Niti spring clip do not loose stiffness
• Results
! No difference was found between “as
received” and “used” brackets in the
SPEED Group.
! The In Ovation group showed
extensive “relaxation” (50% decrease
in stiffness) after use.
! Neither group showed signs of
permanent deformation.

47. Aging of the Spring Clip
• Performance and aging depend on the alloy composition of
the Spring Clip
• Clinical relevance
! Inability of the relaxed clip to apply forces due to aging
! Inadequate engagement of the wire into the bracket slot may arise in the
last stages of treatment when rectangular wires are inserted
! Undesirerable outcome on associated mechanotherapeutical schemes

50. Plaque retention by self-ligating vs elastomeric orthodontic
brackets: Quantitative comparison of oral bacteria and detection
with adenosine triphosphate-driven bioluminescence
(Am J Orthod Dentofacial Orthop 2009;135:426.e1–426.e9)
• Methods: Patients (ages, 11-17 years) were bonded with SL and E brackets in 14
maxillary and 12 mandibular arches by using a split-mouth design.
! Recall visits were at 1 and 5 weeks after bonding.
• Editor's summary:
! The findings indicate that self-ligating appliances might promote reduced retention of
bacteria, including streptococci, than appliances with elastomeric ligation.
! Of course, you must assume that this advantage would be lost by placing
elastomeres over the self-ligating brackets.
