DIFFERENCE 2 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 ( B racketless A nti R esorption) 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.

8 NuBrace demonstrated more gradual and >2 times longer duration of tooth movement v. the alternative unlaminated aligner.
STAGES OF LAMINATE DECOMPRESSION 9 Both laminates compress upon insertion. Stiffer outer layer initiates tooth movement. Inner layer allows additional movement
#1 orthodontic concern is root and bone resorption minimized by gradual tooth movement. Longer duration of tooth movement leads to less chair time. 10 DISCUSSION

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.
