Solution Overview

Problem

Conventional dental prosthesis treatment methods using alginate impressions result in patient discomfort and inaccuracy, leading to potential prolonged or inadequate treatment due to the need for manual margin line drawing and cord-winding operations, which are time-consuming and painful.

Innovation Solution

An integrated library method that allows for the selection, display, registration, and storage of 3D abutment models with associated margin line data, enabling automatic generation and editing of margin line data, reducing the need for manual drawing and minimizing patient discomfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional alginate impression taking is used, then patient discomfort and inaccuracy occur, but the process is simple and quick

Engineering Contradiction:

Improvedimensional accuracyVSAvoidpatient discomfort

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical alginate impression system with a 3D scanning system. The 3D scanner captures digital data of the patient's oral cavity without requiring physical impression materials, thereby eliminating patient discomfort from foreign body insertion while maintaining high dimensional accuracy through digital measurement.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a digital copy of the patient's oral cavity through 3D scanning. Instead of using physical alginate impressions that cause discomfort, the system generates a precise digital model that can be stored and reused, eliminating the need for repeated physical impression taking while maintaining measurement accuracy.

Inventive Principle:

Principle #26Copying

2Manufacturing precision

If manual margin line drawing and cord-winding operations are performed, then treatment accuracy can be achieved, but the process becomes time-consuming and painful

Engineering Contradiction:

Improveprosthetic treatment accuracyVSAvoidtreatment time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary 3D scanning of the patient's oral cavity to capture all necessary dimensional data before treatment begins. The margin line data is pre-calculated and stored in the database, eliminating the need for time-consuming manual margin line drawing and cord-winding operations during subsequent treatment steps while maintaining treatment accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically generates and stores margin line data based on the 3D scanned models without requiring manual intervention. The database stores pre-processed margin line information that can be automatically retrieved and applied during treatment, eliminating the need for repeated manual measurements and reducing overall treatment time while maintaining precision.

Inventive Principle:

Principle #25Self-service

3Measurement precision

If 3D scanning is used to acquire precise data, then patient discomfort is reduced and treatment accuracy is improved, but the system complexity increases

Engineering Contradiction:

Improveoral cavity data accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates a multi-functional integrated library system that handles 3D scanning, data storage, margin line calculation, and prosthetic design in a single unified platform. This universal system eliminates the need for multiple separate devices and manual processes, reducing overall system complexity while maintaining high measurement precision through integrated 3D scanning capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Manufacturing precision

If margin line data is manually drawn and stored, then treatment accuracy can be maintained, but the process is repetitive and inefficient

Engineering Contradiction:

Improvemargin line accuracyVSAvoidtreatment efficiency

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The system automatically generates and stores margin line data based on 3D scanned models without requiring manual drawing for each case. The database stores pre-processed margin line information that can be automatically retrieved and applied during treatment, eliminating repetitive manual operations and significantly improving treatment efficiency while maintaining margin line accuracy through automated calculation based on precise 3D geometry.

AI summary

A method for using an integrated library according to the present invention is characterized in that when a user selects a target position, an abutment to be applied to an oral cavity of a patient is loaded, and when an abutment model is selected in a database thereof, margin line data linked with the selected abutment model can be displayed together. In addition, the margin line data is not only simply displayed in a thumbnail displaying step, but also can be linked with oral data to be used together. The margin line data can also be edited so as to have a more appropriate form according to the user's need and be stored, such that the existing margin line data can be substituted with edited margin line data.
