Orthodontic Bonding

Since the development of direct orthodontic bonding, various new developments have been made to help improve the technique. These developments have focused on improving bond strength, decreasing bonding time, reducing the number of bonding steps, and decreasing adhesive remnants. All these advances have worked towards creating the most efficient bonding protocol while maintaining enamel health during treatment and after debonding. As newer and more efficient products are marketed, we must also evaluate their interactions with other orthodontic products available to practitioners, as well as their effects on enamel. Gwineett and Gorelick5 found that many of the practiced and recommended modalities of bonding being used were harmful …show more content…
This feature differentiates these materials from conventional adhesives. Transbond plus colour change adhesive, introduced by 3M Unitek16, appears pink in colour initially and colour fades away after light curing. It also has additional properties of moisture tolerance, fluoride release and it can be used with metal and ceramic brackets (3M) 16. Grengloo is a two way colour change adhesive introduced by Ormco Corporation. As it is warmed to body temperature, the colour disappears, remaining clean throughout treatment. When debonding, by simply introducing a short blast of cool air or water (which will lower the bonding surface temperatures), Grengloo will turn to green colour again for easy and thorough clean up …show more content…
Romano et al18 found that the shear bond strength of Transbond plus was increased (17.5±4.5 MPa) when used along with Transbond plus self etching primer. Grengloo showed the lowest mean shear bond strength (7.36±1.93 MPa) among the four adhesives tested in the present study. Türkkahraman et al17 evaluated the mean shear bond strength of Grengloo and found it as 15.3±3.3 MPa. This was also higher than the shear bond strengths shown by Transbond Plus Colour Change Adhesive, and Blūgloo. This is contradictory to the present study results, where Grengloo exhibited the lowest mean shear bond strength, though the differences among the three groups were not statistically significant (Table 3). A previous study by Vicente et al19 found a significant increase in bond strength of Transbond XT adhesive when brackets were bonded with Ormco’s Orthosolo primer compared with using Transbond XT primer. Despite using Ormco’s Orthosolo primer the shear bond strength of Grengloo was the least among all the four groups in the present study. The mean shear bond strength of Padlock was 8.08±1.46 MPa in the present study. Lack of any similar study in the literature has left no scope for direct comparison of these
