Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing dental alignment technologies primarily focus on tooth alignment without effectively addressing the displacement of the chewing plane, leading to unfavorable outcomes such as blockages and resistance from the user when the devices are removed.

Innovation Solution

A series of devices and methods that include jaw devices with defined contact areas and height elements to adjust and relearn the chewing plane, allowing for incremental and neuromuscular relearning of the occlusal plane, either directly or through an indirect approach, with optional attachments for precise tooth movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If dental alignment devices focus only on tooth alignment, then tooth positioning is improved, but the chewing plane displacement is not achieved and user resistance occurs

Engineering Contradiction:

Improvetooth alignment precisionVSAvoidchewing plane stability

Core Design Contradiction:

Manufacturing precisionVSReliability

Solution Approach 1:

The patent combines tooth alignment function and chewing plane displacement function into a single integrated device. The aligner includes both alignment elements for tooth positioning and occlusal elements for chewing plane displacement, allowing simultaneous achievement of both functions without requiring separate devices

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The dental aligner is designed as a multi-functional device that performs both tooth alignment and chewing plane displacement. The device universally addresses multiple dental correction needs through integrated structural elements rather than requiring separate specialized devices

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If the chewing plane is displaced without neuromuscular relearning, then structural change is achieved, but user resistance and blockages occur

Engineering Contradiction:

Improvechewing plane displacementVSAvoiduser acceptance

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The device prepares the chewing plane for future permanent displacement by implementing preliminary structural changes. The occlusal elements create early contact areas that guide the chewing plane toward its final position, allowing gradual adaptation before complete displacement

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The aligner provides continuous feedback to the user's neuromuscular system through defined contact areas on the occlusal elements. These contact areas guide the chewing movements and provide sensory feedback that facilitates neuromuscular relearning and acceptance of the new chewing plane position

Inventive Principle:

Principle #23Feedback

3Loss of time

If devices are removed after alignment, then treatment is complete, but resistance and blockages reappear

Engineering Contradiction:

Improvetreatment durationVSAvoidalignment stability

Core Design Contradiction:

Loss of timeVSStability of the object's composition

Solution Approach 1:

The device performs preliminary displacement of the chewing plane before complete treatment completion. This preliminary action prepares the occlusal relationships in advance, ensuring that when the device is removed, the chewing plane is already positioned to maintain alignment stability without resistance or blockages

Inventive Principle:

Principle #10Preliminary action

AI summary

A series (100) of devices for assisting in the displacement of the chewing plane of a person (P) is explained, comprisingat least two devices (10),wherein the devices (10) each comprise at least one jaw device (11, 12),wherein the at least one jaw device (11, 12) comprises an upper jaw device (11) and/or a lower jaw device (12),and wherein the devices (10) are designed to be worn by the person (P) according to a predetermined sequence.In at least one device (10.1, 10.2), the at least one jaw device (11, 12) comprises at least one height element on a first side. At least two contact areas, preferably local contact areas, are formed on the at least one height element at mutually different positions of molar elements. At least one further contact area is formed on a second side of the at least one jaw device (11, 12), in particular a further local contact area. The at least three contact areas define the plane (GE),wherein the plane (GE) deviates from a starting chewing plane of the person (P) or from a current chewing plane of the person (P) with respect to its inclination changed by the at least one height element in a frontal section or sagittal section and/or deviates with respect to its height position changed by the at least one height element, andwherein in at least one other device of the series (100) a different inclination in a frontal section or sagittal section and/or a different height position of the respective plane is adjusted by at least one further height element, which differs from the at least one height element in the adjusted height.
