DIFFERENCE
Outer stiffer laminate allows initial tooth movement.
Inner softer laminate allows:
Greater flexibility, retention and patient comfort.
Longer duration of tooth movement per aligner.
Less stress to teeth and bone.

NuBrace Treatment Difference
1. Each step clinician has option to:
•
•
•
Continue as planned.
Made additional changes.
Submit a new impression.
2. Hence: Dentist Exact Not Computer
Projected.
Internal flexibility allows closer margins to minimize
bacterial infiltration and improved retention
4
BAR (Bracketless Anti Resorption)
•
•
•
Groove placed on digital model for additional orthodontic
movement which translate into BAR inside the aligner.
Upon insertion, BAR gradually recovers for greater
orthodontic movement.
Void of unsightly attachments, improved oral hygiene and
esthetics.
Upon insertion, BAR initially
compresses gradually
recovers for greater
orthodontic movement.

NuBrace demonstrated more gradual and >2 times longer duration
of tooth movement v. the alternative unlaminated aligner.

STAGES OF LAMINATE DECOMPRESSION
Both
laminates
compress
upon
insertion.
Stiffer outer
layer
initiates
tooth
movement.
Inner layer
allows
additional
movement
9
DISCUSSION
• #1 orthodontic concern is root
and bone resorption minimized
by gradual tooth movement.
• Longer duration of tooth
movement leads to less chair
time.

Less stress to
teeth and bone
More fringe,
greater stress

1270 Laminated Orthodontic
Removable aligner for Molar
Uprighting
T. Kalili, A.A. Caputo, R. Mito, I.
Nishimura, et al
Laminated Orthodontic Removable
aligner for Molar Uprighting
ABOVE – Conventional molar uprighting appliance showing significant
localized tensile stress which may be damaging to teeth and bone.
ABOVE – NuBrace showing more uniform areas of stress to allow for a
more gradual load with less localized stress to teeth and bone.
ABOVE – Conventional molar uprighting appliance showing unwanted
stress in the anterior sextant unrelated to molar uprighting.
ABOVE – NuBrace does not require attachments + or arch bows for
tooth movement therefore, minimal stress in unrelated areas.
