Synchronized Tooth Movement Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthodontic treatment planning methods using 3D scanning and computerized planning are cumbersome and time-consuming, leading to inaccuracies in gum geometry modeling, potential tooth movement errors, and increased costs due to the complexity of defining tooth and gum boundaries, which results in patient discomfort and reduced treatment effectiveness.
Innovation Solution
A control method and system for synchronized tooth movement using a tooth movement control system (TMCS) with a processor and memory to execute individual tooth movement plans, incorporating local control modules that adjust movement speed and direction to avoid collisions and adhere to specific objectives, such as Andrews' Six Keys To Occlusion, while using artificial intelligence to predict optimal movement paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional 3D scanning and computerized planning methods are used to model tooth and gum boundaries, then treatment planning can be performed, but the process becomes cumbersome and time-consuming, resulting in inaccurate gum geometry modeling and potential tooth movement errors
Solution Approach 1:
The patent applies preliminary action by pre-defining standardized tooth boundary surfaces and gum geometry models before actual treatment planning. These pre-established geometric frameworks allow the system to rapidly generate accurate treatment plans without performing time-consuming 3D scanning and boundary definition during the planning phase, thus resolving the contradiction between modeling accuracy and planning time.
2Manufacturing precision
If trim and hole filling methods are used to create individual tooth and gum models, then models can be generated, but boundary surfaces must be arbitrarily defined, causing modeling inaccuracies and software inability to model accurately due to model collisions
Solution Approach 1:
The patent applies parameter changes by transitioning from arbitrary boundary definition to standardized anatomical landmark-based boundary definition. By changing the defining parameters from user-defined arbitrary surfaces to objectively measurable anatomical landmarks, the system achieves consistent and accurate tooth model boundaries without increasing process complexity.
3Adaptability or versatility
If modeled tooth movements are allowed to be relaxed, then software can enable movements, but physically impossible movements may occur causing teeth to be pushed into one another and aligner shells to stretch excessively, creating patient discomfort
Solution Approach 1:
The patent applies feedback by implementing a validation mechanism that continuously monitors proposed tooth movements against anatomical constraints and physical feasibility criteria. The system provides feedback when a proposed movement would cause model collisions or excessive aligner deformation, preventing physically impossible movements from being executed, thus eliminating patient discomfort while maintaining movement flexibility within safe limits.
4Manufacturing precision
If final refinements are performed to correct gaps between teeth caused by modeling inaccuracies, then treatment accuracy can be improved, but costs increase and patient dissatisfaction remains
Solution Approach 1:
The patent applies preliminary action by establishing accurate standardized boundary surfaces and gum geometry models at the beginning of treatment planning, before any tooth movement is simulated or executed. This preliminary establishment of precise geometric frameworks prevents modeling inaccuracies from occurring in the first place, eliminating the need for costly final refinement procedures and associated patient dissatisfaction.

AI summary
A system includes a plurality of tooth models each including computer code controlling its movement. The system also includes a tooth movement control system (TMCS) with a processor executing a dental manager module and with memory scoring a different tooth movement plan for each of the tooth models. In practice, the tooth movement plans are stored in the memory of each of the tooth models (e.g., a different tooth movement plan for each tooth model). Then, during tooth movement operation, each of the local control modules independently controls the tooth model to execute the tooth movement plan stored in the memory of the tooth model.
