ABSTRACT

Nowadays, there is an increased demand for fixed orthodontic treatment due to the growing importance of aesthetics. Brackets and molar tubes are generally bonded to the enamel surfaces using a direct bonding technique. Additionally, the use of lightcured resin materials has provided clinicians with a longer working time during the direct technique, allowing them extra time to verify the accuracy of the final positions of the brackets. However, correct positioning of posterior orthodontic attachments remains a challenge due to the limited placement angle in the direct bonding technique.

Approximately half a century ago, the indirect bonding technique was introduced to address issues with incorrect bracket positioning and reduce clinical chair time. The working time was further extend ed with the use of lightcured adhesives. In the following years, a transfer tray was prepared by posi tioning brackets on the plaster models and then the brackets were then bonded to the teeth indirectly using chemically polymerized resin. This technique was later modified.

With technological advancements, certain steps of the indirect bonding technique have been eliminated in digital orthodontics, and the methods for producing transfer trays have evolved in clinical practice. In digital bonding, transfer trays can be produced in two ways. In the direct technique, the tray is di rectly created using a threedimensional (3D) printer. In the indirect technique, the tray is fabricated indirectly from 3Dprinted study models using silicone or thermoplastic materials.
