Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prosthetic and orthodontic procedures often result in less than ideal tooth preparation and treatment due to a lack of reliable and precise planning and execution methods.
Innovation Solution
The development of improved systems, methods, and devices for repositioning teeth, which involve building detailed three-dimensional models of the patient's dentition, generating treatment plans with step-by-step visualizations of material removal, and using advanced imaging and simulation tools to guide dental practitioners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional prosthetic and orthodontic procedures are used with educated guesses for tool selection and material removal, then the treatment process is simpler and faster to plan, but the manufacturing precision and reliability of tooth preparation deteriorates
Solution Approach 1:
The system performs preliminary digital planning and simulation of tooth preparation before actual clinical execution. Treatment plans are designed in advance with precise material removal paths, tool selections, and step-by-step visualizations generated through software modeling, allowing practitioners to review and adjust plans before touching the patient's teeth.
Solution Approach 2:
The system creates digital copies (3D models) of the patient's dentition that can be manipulated and analyzed virtually. These digital twins allow for precise measurement, simulation of different preparation approaches, and visualization of outcomes without affecting the actual teeth during the planning phase.
2Reliability
If detailed three-dimensional modeling and simulation tools are implemented, then the reliability and accuracy of treatment planning improves, but the device complexity and time required for planning increases
Solution Approach 1:
The system maintains continuous workflow between digital modeling, treatment planning, and clinical execution. Once a treatment plan is digitally designed and validated, it can be directly transferred to clinical use with minimal interruption, and updates can be made continuously as treatment progresses based on actual tooth preparation feedback.
Solution Approach 2:
The system replaces manual measurement and estimation methods with automated digital imaging and computer-aided design tools. 3D scanning, virtual reality visualization, and software-based treatment planning substitute for traditional manual techniques, reducing both planning time and increasing precision simultaneously.
3Ease of operation
If step-by-step visualizations with tool selection and material removal paths are generated, then the ease of operation during treatment improves, but the device complexity and computational requirements increase
Solution Approach 1:
The system provides self-guided treatment execution through detailed visualizations that show practitioners exactly what steps to take, which tools to use, and what material removal is required. The software acts as a virtual assistant that guides the practitioner through each step of the procedure, reducing the need for extensive expert knowledge and experience.
Solution Approach 2:
The treatment plan is divided into discrete, manageable steps with specific objectives, tool selections, and expected outcomes for each step. This segmentation allows practitioners to focus on one step at a time, reducing cognitive load and improving execution accuracy while the software handles the complexity of coordinating all steps.
