Indirect Bonding (Upper)
A tray is formed with dual hard Biocryl and soft silicone trays. The transparent tray can be used in combination with light-cured adhesives. Low-friction composites are placed on each bracket to eliminate undercuts under the bracket wings and prevent penetration of silicone material into the bracket slots. This procedure allows easier tray removal and reduces the risk of bracket debonding during the tray removal and ligation time with low friction ligatures.
