Guided bonding devices (GBDs) demonstrate high accuracy for bracket placement in vitro, even with severe dental crowding. This technology shows promise for both crowded and uncrowded orthodontic treatments.
Area of Science:
- Orthodontics
- Biomaterials Engineering
- Dental Technology
Background:
- Assessing the precision of bracket bonding is crucial for orthodontic treatment outcomes.
- Guided Bonding Devices (GBDs) offer a potential solution for improving bracket placement accuracy.
- The efficacy of GBDs in managing dental crowding requires further in vitro investigation.
Purpose of the Study:
- To evaluate the accuracy of bracket bonding using Guided Bonding Devices (GBDs) in vitro.
- To determine if GBDs are suitable for precise bracket placement in dentitions with varying degrees of crowding.
Main Methods:
- Utilized fifteen 3D-printed resin model sets categorized into mild, moderate, and severe crowding groups.
- Performed virtual bracket bonding, generated corresponding GBDs, and 3D printed them.
- Bonded brackets to resin models using GBDs and analyzed deviations between planned and actual bracket positions.
Main Results:
- No immediate bracket bonding failures were observed across all groups.
- Linear and angular deviations were consistently below 0.5 mm and 2°, respectively, irrespective of crowding severity.
- A tendency for lingual deviation and buccal crown torque was noted, with specific rotational tendencies in mild and severe crowding groups.
Conclusions:
- Guided Bonding Devices (GBDs) exhibit high bracket bonding accuracy across different dental crowding degrees.
- The findings suggest GBDs are a reliable tool for precise bracket placement in both crowded and uncrowded dentitions.
- GBDs hold potential for widespread application in orthodontic bracket bonding procedures.
