Do the Various Indirect Bonding Techniques Provide the Same Accuracy for Orthodontic Bracket Placement? (Randomized Clinical Trial).
Int J Dent
January 2024
Orthodontic Department, College of Dentistry, University of Baghdad, Baghdad, Iraq.
Background: For orthodontic treatment to be effective, bracket placement must be precise to make the finishing stage easier, leading to an ideal occlusion with minimal intervention. This study aimed to evaluate the accuracy of manual and digital bracket positioning techniques utilizing computer-aided design and computer-aided manufacturing (CAD/CAM) jigs, 3D-printed indirect bonding trays (IBT), and double-layer vacuum-formed thermoplastic IBT.
Methods: This study was done by scanning the dental arch of 30 orthodontic patients.

Background: Improving bracket placement accuracy through computer-aided design and a bracket navigation set supported by augmented reality (AR).
Methods: A technical workflow was developed for implementing AR-assisted orthodontic bracket positioning through a smartphone application. This innovative approach eliminates the need for three-dimensional radiation imaging or physical guides, making it a safe and convenient option for clinical use by overlapping the digitally planned bracket position over the patient clinical crown for a precise recommendation of bracket positioning.
Objectives: To study whether and how the clinical experience of the operator affects the accuracy of bracket placement using guided bonding devices (GBDs) in vitro.
Materials And Methods: Five resin models were bonded virtually with brackets, and the corresponding GBDs were generated and three-dimensionally printed. Nine operators, which included three dental students, three orthodontic students, and three orthodontists, bonded the brackets on the resin models using GBDs on a dental mannequin.
ImTooth: Neural Implicit Tooth for Dental Augmented Reality.
IEEE Trans Vis Comput Graph
February 2023
The combination of augmented reality (AR) and medicine is an important trend in current research. The powerful display and interaction capabilities of the AR system can assist doctors to perform more complex operations. Since the tooth itself is an exposed rigid body structure, dental AR is a relatively hot research direction with application potential.

Background: This study aimed to evaluate the effects of offset design on the accuracy of bracket placement for computer-aided design and computer-aided manufacturing (CAD/CAM)-guided bonding devices (GBDs) in vitro.
Methods: Eight dental models were selected. Seven types of GBDs were designed and three-dimensionally (3D) printed for each model, including one without any offset and the other six with translation offsets (TF) and expansion offsets (EF) of 0.
