Orthodontic Bonding Template for Precise Bracket Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthodontic bracket placement methods face challenges in achieving precise positioning, especially on severely crowded teeth or when the bonding surface is obstructed, and require meticulous moisture control, prolonging the procedure and impairing accuracy.
Innovation Solution
A digital template is created based on a patient's teeth model, simplifying anatomical features and using virtual brackets to guide precise placement, allowing for direct bonding with a removable guide that minimizes variations in distance and angles.

Engineering Contradiction Analysis
1Ease of operation
If direct bracket placement is performed on severely crowded teeth or obstructed bonding surfaces, then the procedure can be completed in the dental chair, but the treatment professional has difficulty accessing the optimal position and seeing the precise bracket location, reducing placement accuracy
Solution Approach 1:
The invention applies preliminary action by pre-positioning brackets on a plaster model or digital replica of the patient's dentition before the actual bonding procedure. This allows the treatment professional to accurately determine bracket positions in advance, overcoming the difficulty of accessing and visualizing optimal positions during direct placement in the dental chair.
Solution Approach 2:
The invention uses an intermediary approach by introducing a transfer tray or registration template as a mediator between the planning stage and the actual bonding procedure. This intermediary device transfers the pre-determined bracket positions from the model to the patient's teeth, ensuring placement accuracy without requiring direct visualization during bonding.
2Manufacturing precision
If indirect bonding with full plaster models and transfer trays is used, then bracket placement accuracy is improved, but the procedure becomes labor intensive and fabrication is complex and time-consuming
Solution Approach 1:
The invention applies segmentation by dividing the indirect bonding process into separate components: a simplified registration template or key features of the dentition are captured rather than creating complete plaster models. This segmentation reduces the complexity of tray fabrication while maintaining the ability to accurately transfer bracket positions.
Solution Approach 2:
The invention extracts only the essential features needed for accurate bracket positioning, such as key anatomical landmarks or simplified digital models, rather than requiring complete and intricate plaster models. This extraction approach maintains placement accuracy while significantly reducing fabrication complexity and time.
3Reliability
If moisture control measures are implemented during direct bonding, then bonding strength is maintained, but the procedure is prolonged and the accuracy of bracket placement is impaired
Solution Approach 1:
The invention applies preliminary action by performing moisture control and bracket positioning in separate stages. The registration template or transfer tray is prepared in advance when moisture control is less critical, allowing accurate positioning to be established before the actual bonding procedure where moisture control becomes paramount.

AI summary
A dental template for positioning one or more objects on teeth of a patient is disclosed. The dental template can include a plurality of teeth-receiving cavities that further incldue occlusal surface that correspond to occlusal surfaces of teeth. The template can also inclue buccal surfaces that conform to buccal tooth surfaces. The buccal surfaces of the template can include openings to control placement of one or more objects on the patient's teeth.
