In orthodontics, the removal of a bracket from a tooth.


Removal of orthodontic brackets and residual adhesive, after which the tooth surface is returned to its normal contour.


n a procedure by which brackets and bonding resin are removed and the surface of the tooth is restored to its previous condition.

6) show more evidences of ductile fractures as more holes and fibrils formed by the deformation and debonding of PBAC can be observed, especially with the increasing number of cis-CHRMs in PBAC.
We present some recent results on mathematical models of debonding of engineering thin structures.
This contraction places the interface between the restoration and the tooth under stress and may result in tooth-composite interfacial debonding, cuspal deflection and enamel cracking which are implicated as the primary reasons for failure of resin bonded restorations.
Mechanical debonding of dry lap pulp to improve defibration performances even with existing mill technology.
During the first stage of fatigue, a multitude of microscopic transverse cracks initiate either from (1) single filament breakage randomly distributed in the material or from (2) defects such as a weak fiber/matrix interface and voids, which directly lead to a rapid axial modulus reduction; in the second stage, the dominant failure modes are delamination and fiber/matrix interface debonding, and the stiffness reduces slowly and progressively before the final stage, where more severe failure modes occur (such as unstable delamination and fiber breakage), and a sudden drop in axial modulus can be observed.
Reduction in flexural capacity was observed with temperature, failure mode was also shifted from flexural mode to debonding mode of failure at elevated temperature.
This behavior is the result of the progressive disruption of the matrix; the weakest element of the composite, followed by debonding and possible delamination.
Fiber debonding and breakage occurred simultaneously and were the first defects to initiate damage in the examined materials.
The infrared and video data collected for each of the 11 decks was analyzed to quantify and map overlay debonding, rebar-level delamination, patching, and spalling.
