Solution Overview

Problem

Current CAD technologies for designing dental restorations are inefficient for creating larger dental restorations like partial or full dentures, as they require individual modification of each tooth, which is time-consuming and often results in aesthetic discrepancies.

Innovation Solution

A computer-implemented method that allows users to design dental restorations using a composed set of interrelated teeth, enabling collective modification and mirroring, cloning, and fitting to a virtual retention means, facilitating the creation of aesthetically pleasing and symmetrical designs for larger restorations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If individual tooth design and modification is used for each tooth in larger dental restorations, then each tooth can be customized, but the design time becomes excessively long and aesthetic consistency is difficult to maintain

Engineering Contradiction:
Improvedesign timeVSAvoidaesthetic consistency
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent combines multiple individual tooth designs into a single composed set representing an entire dental arch. The system allows selection and modification of entire sets of teeth rather than individual teeth, maintaining aesthetic consistency through coordinated design while significantly reducing design time for large restorations like dentures and bridges.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the dental arch into composed sets of teeth that can be independently selected and modified. Each composed set represents a complete functional and aesthetic unit that can be applied to the patient's oral situation, allowing efficient design while maintaining the ability to customize specific areas when needed.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If traditional CAD technology stores and arranges teeth separately, then individual tooth selection is flexible, but designing larger restorations with multiple teeth becomes very time-consuming

Engineering Contradiction:
Improvetooth selection flexibilityVSAvoiddesign time for multiple teeth
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent merges multiple individually stored teeth into composed sets that represent complete dental arches or portions thereof. This allows the user to select and apply entire sets of coordinated teeth with a single operation, dramatically reducing the time required to design restorations involving multiple teeth while preserving the ability to access and modify individual teeth when needed.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Disclosed is a computer-implemented method of designing a number of dental restorations for a patient, wherein the method comprises: - selecting a composed set of teeth comprising a number of teeth, where the number of teeth are arranged spatially relative to each other forming a high aesthetic composition; - applying the composed set of teeth to a virtual three dimensional representation of the patient's present oral situation to obtain an initial set of teeth; - optionally modifying one or more parameters of one or more of the teeth in the initial set of teeth to obtain a finalized set of teeth.
