Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatment planning approaches for orthodontic and restorative treatments are invasive, inefficient, and lack integration, leading to cumbersome workflows and poorer patient outcomes.
Innovation Solution
An integrated ortho-restorative workflow and software platform that allows concurrent planning of orthodontic therapy and restorative work, using systems and methods for planning a combined orthodontic and restorative treatment, including repositioning teeth and altering tooth mass through restorative objects and tooth removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If restorative treatment procedures are used to repair or correct the shape of a patient's tooth, then the aesthetics and function of the tooth are improved, but the invasiveness of the procedure increases and tooth mass is reduced
Solution Approach 1:
The system performs preliminary tooth mass analysis by comparing scanned tooth images with target tooth models before treatment begins. This allows the clinician to visualize and plan the exact amount of mass to be removed or added in advance, enabling informed decisions about the necessary restorative procedures while minimizing invasiveness.
Solution Approach 2:
The system creates a digital copy (scan) of the patient's current tooth structure and compares it with a target tooth model. This digital representation allows for virtual simulation of treatment outcomes and precise calculation of mass changes required, eliminating the need for excessive physical removal of tooth material.
2Shape
If excessive tooth mass reduction is performed during restorative treatment, then the shape correction is achieved, but the integrity and vitality of the tooth is compromised
Solution Approach 1:
The system calculates and visualizes the precise amount of tooth mass that needs to be removed or added before the actual treatment. This preliminary planning ensures that only the minimum necessary mass is altered to achieve the desired shape correction, thereby preserving tooth integrity and vitality.
Solution Approach 2:
The system allows for dynamic adjustment of treatment parameters including the amount of mass to be removed or added. By modifying these parameters based on the comparison between scanned and target tooth models, the system optimizes the balance between achieving shape correction and maintaining tooth strength.
3Reliability
If separate orthodontic and restorative treatment plans are used, then each treatment can be optimized independently, but the workflow becomes cumbersome and time-consuming
Solution Approach 1:
The system merges orthodontic and restorative treatment planning into a single integrated workflow. The tooth mass analysis tool combines with orthodontic simulation capabilities to allow concurrent planning of both treatments, enabling the clinician to visualize and adjust both orthodontic movements and restorative mass changes in one unified interface.
Solution Approach 2:
The treatment planning system is designed as a multi-functional platform that handles both orthodontic and restorative procedures. This universal system eliminates the need for separate planning processes and allows for integrated optimization of both treatment types while improving overall workflow efficiency.
4Ease of manufacture
If traditional treatment planning approaches are used, then the basic treatment can be delivered, but the integration of orthodontic and restorative procedures is insufficient
Solution Approach 1:
The system combines orthodontic and restorative treatment planning capabilities into a single integrated platform. The tooth mass analysis tool works alongside orthodontic simulation features to allow concurrent planning, visualization, and adjustment of both treatments, providing comprehensive integration that adapts to various treatment scenarios.
Solution Approach 2:
The system provides dynamic adjustment capabilities where the clinician can modify both orthodontic and restorative parameters interactively. The integrated platform allows real-time visualization of how changes in one treatment area affect the other, enabling flexible adaptation to patient-specific needs while maintaining seamless procedure integration.

AI summary
Systems and methods for treatment planning are provided. In some embodiments, a method includes: receiving a plurality of digital representations of a plurality of intermediate tooth arrangements configured to adjust a patient's teeth from an initial tooth arrangement toward a target tooth arrangement, where the target tooth arrangement comprises a change in mass of at least one tooth relative to the initial tooth arrangement; outputting a first heatmap showing a difference in tooth mass between a first intermediate tooth arrangement and the target tooth arrangement; outputting a second heatmap showing a difference in tooth mass between a second intermediate tooth arrangement and the target tooth arrangement; and receiving a user input selecting the first intermediate tooth arrangement or the second intermediate tooth arrangement for use in a treatment plan based on a comparison between the first heatmap and the second heatmap.
