Solution Overview

Problem

Current oral treatment methods lack precision and accuracy due to limited space within the patient's mouth, often relying on visual inspection for drilling, which can lead to suboptimal results and tissue damage.

Innovation Solution

A dental template is created using 3D data and CT imaging to guide dental tools with optimal drilling paths and angles, minimizing tissue damage and ensuring precise treatment by manufacturing guiding paths for drilling tools based on anatomical and functional parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If visual inspection method is used for drilling, then the treatment process is simple and quick, but the precision and accuracy of drilling angle and depth are insufficient

Engineering Contradiction:
Improvedrilling precisionVSAvoidtreatment process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent creates a 3D digital model of the patient's oral cavity and pre-calculates the optimal drilling paths, angles, and depths before the actual treatment. This preliminary planning phase allows the dentist to review and confirm the treatment plan, ensuring high precision while keeping the actual treatment process simple and quick.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces a computer-based planning system as an intermediary between the dentist's visual inspection and the actual drilling operation. This intermediary processes the 3D data, calculates optimal parameters, and provides guidance during treatment, thereby improving precision without significantly increasing the complexity of the treatment process for the dentist.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If guided template method is used, then the precision of drilling angle and depth is improved, but the treatment process becomes more complex

Engineering Contradiction:
Improvedrilling angle and depth accuracyVSAvoidoperation simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces complex physical guiding templates and mechanical alignment devices with a digital planning system that calculates and displays optimal drilling parameters on a computer screen. The dentist can visualize the exact drilling path and adjust parameters digitally, which is simpler and more flexible than using physical guides while maintaining high measurement precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If minimal drilling is applied, then the damage to surrounding tissues is reduced, but the difficulty of achieving precise drilling increases

Engineering Contradiction:
Improvetissue damageVSAvoiddrilling precision
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent uses 3D imaging data to precisely determine the optimal drilling parameters (angle, depth, path) that minimize tissue damage. By changing and optimizing these parameters based on the specific anatomical structure of each patient, the system achieves minimal invasive treatment while maintaining high drilling precision.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present invention relates to a method for the manufacturing of an oral template from a 3D digital data, such that an essentially optimal restoration process of the original structure and functionality of a patient's oral cavity become applicable, comprising: a) prior to a dental treatment, recording and digitizing a first three-dimensional (3D) data that represents the original anatomical structure of at least one tooth within the oral cavity of a patient, for generating a first virtual model that reflects the original anatomical structure of said at least one tooth (i.e.,the virtual model of the original tooth);b) processing said first 3D data for generating a second virtual model that reflects the form of said at least one tooth after applying an optimal treatment as defined by medical practice parameters (i.e., the virtual model of an optimal treated tooth); c) generating a third virtual model of a dental template to be mounted on top of said at least one tooth according to said first and second virtual models, wherein said dental template includes guiding paths for achieving an optimal dental treatment as defined by the medical practice parameters (i.e., virtual model of the dental template); and d) manufacturing said dental template according to said third virtual model, such that a dental treatment can be applied to said at least one tooth with a dental tool via the guiding paths of said template whenever said dental template is mounted on top of said at least one tooth, such that after finishing applying the dental treatment to the at least one tooth with the dental template an essentially optimal treated tooth is obtained.
