About
The windowed direct-indirect bonding is a new bonding technique that could provide a simple and cheap method for fast and precise brackets bonding. There are still not enough studies to evaluate the effectiveness of this method in terms of accuracy, bonding time, bonding failure and cost.
This study is designed to answer these questions and compare the forementioned bonding technique with digital indirect bonding and finally provide the clinician a recommendation on the best bonding technique. This study introduces as well a new method of fabrication of the windowed template using Fusion Deposition Modeling (FDM) 3D printing technology.
Full description
This study will compare two bonding techniques, the windowed bonding technique and digital indirect bonding. They will be compared regarding accuracy, bonding time, bonding failure and cost. Patients will be selected according to the eligibility criteria, random sequence generation and blind allocation will be performed. ( A randomized clinical trial). Patients will be allocated to one of the groups either the windowed bonding or the digital indirect bonding.
Both groups will undergo similar steps initially. First, the patient's teeth will be digitized using an intraoral scanner. Then using 3 shape software, the model will be prepared and brackets will be positioned virtually on the 3D models. Then, in the windowed bonding technique, the windowed tray will be designed and later 3D printed, while in the digital indirect technique the model with the brackets will be 3D printed and a tray will be fabricated on the model manually.
After the fabrication of the tray, the brackets will be transferred to the patient using the tray or directly bonded using the windowed tray guide.
The patient's teeth will be scanned after bonding and this 3D model will be compared with the initial brackets setup that was made previously on the software.
