Solution Overview

Problem

Current dental prosthesis fitting methods are complex, require large diameter implants that necessitate multiple drilling operations, result in bulky and unattractive prostheses, and are poorly suited for individuals with reduced bone mass, leading to inefficient and aesthetically unsatisfactory outcomes.

Innovation Solution

A dental prosthesis fitting kit comprising an implant bar with wells of specific diameters (between 2.5 and 3 mm) and a guide for simplified implantation, along with smaller diameter osteosynthesis screws and implants, allowing for precise placement and reduced drilling requirements, while maintaining mechanical stability and aesthetic appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If large diameter implants (>3mm) are used, then mechanical stability is improved, but drilling complexity and intervention time increase

Engineering Contradiction:
Improvemechanical stabilityVSAvoiddrilling complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent changes the critical parameter from implant diameter to well diameter in the implant bar. By maintaining small implant diameters (2.2-3.5mm) while using a structural bar system, the patent achieves mechanical stability without requiring large diameter implants that would necessitate complex multi-stage drilling operations.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The implant bar acts as an intermediary structure that provides mechanical stability without requiring large implants. The bar with its wells serves as a mediator between the small diameter implants and the functional requirements for stable prosthesis support, eliminating the need for complex drilling while maintaining strength.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If small diameter implants (2.2-3.5mm) are used, then drilling operations are simplified, but mechanical stability may be compromised

Engineering Contradiction:
Improvedrilling operationsVSAvoidmechanical stability
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The patent merges multiple small diameter implants into a unified structural system through the implant bar. Rather than relying on a single large implant for stability, the system combines several small implants (each requiring minimal drilling) that work together through the rigid bar structure to provide equivalent or superior mechanical stability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The implant bar serves multiple functions simultaneously: it provides structural support, connects multiple small implants, distributes mechanical loads, and enables simplified drilling operations. This multi-functionality allows small implants to achieve the mechanical stability traditionally requiring larger implants.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If traditional implant methods are used, then bone integration is achieved, but prosthesis volume becomes bulky and aesthetics deteriorate

Engineering Contradiction:
Improvebone integrationVSAvoidprosthesis aesthetics
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The patent segments the prosthesis support function from the visible prosthesis structure. The implant bar and implants provide the functional bone-integrated support structure, while the prosthesis itself can be designed with realistic aesthetics without requiring bulky thick gum portions for structural support.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent moves the structural support function to a different dimension - the implant bar system operates beneath the gum line and bone level, providing mechanical support without occupying visible space. This allows the visible prosthesis to have natural, realistic dimensions and aesthetics.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Reliability

If complex intervention processes are used, then implant stability is ensured, but intervention time increases

Engineering Contradiction:
Improveimplant stabilityVSAvoidintervention time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The implant bar with pre-formed wells is prepared in advance, allowing implants to be directly inserted into predetermined positions without requiring complex intraoperative drilling and positioning procedures. This preliminary preparation of the implant bar structure significantly reduces intervention time while maintaining implant stability.

Inventive Principle:
Principle #10Preliminary action
