Implant Denture Positioning via Surgical Guide Transfer

Solution Overview

Problem

The challenge in dentistry is accurately positioning implant-supported dentures without the need for costly and time-consuming duplication processes, as existing methods require multiple appointments and complex mapping to ensure proper alignment with implants, often resulting in instability and movement of regular dentures.

Innovation Solution

A denture base positioning system using labial and buccal pins that align with a surgical guide, allowing for precise placement of the denture base corresponding to the implant sites, eliminating the need for a custom support bar and reducing the number of appointments and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional duplication processes and custom support bars are used to position implant-supported dentures, then alignment accuracy with implants is improved, but time consumption and cost increase significantly

Engineering Contradiction:

Improvealignment accuracyVSAvoidtime consumption

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by incorporating positioning elements (such as pins, guides, or registration features) directly into the denture base during manufacturing, before the actual implant placement. These pre-integrated positioning elements enable direct transfer of the surgical guide's positioning information to the denture, eliminating the need for post-implantation adjustment and duplication processes. This allows the denture to be accurately positioned on implants immediately after surgery, reducing the number of appointments required.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts and eliminates the custom support bar from the traditional implant-supported denture system. By removing this intermediate component, the design simplifies the positioning process while maintaining accuracy through direct integration of positioning elements into the denture base itself. This extraction reduces both the complexity of the procedure and the time required for multiple mapping and adjustment appointments.

3Ease of manufacture

If regular dentures are used without implant support, then ease of manufacture is improved, but stability and resistance to movement deteriorate

Engineering Contradiction:

Improveease of manufactureVSAvoidstability

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The patent merges the advantages of regular dentures (ease of manufacture, removability) with the stability of implant-supported dentures. By integrating positioning elements into the denture base that directly interface with implants, the design combines the simplicity of conventional denture construction with the anchorage stability of implant-supported systems. This hybrid approach maintains ease of manufacture while eliminating the movement and instability problems associated with regular dentures.

AI summary

An implant-supported denture placement and alignment system may include a denture apparatus. The denture apparatus may have a denture base and a denture base positioning system. The denture base may be connectable to implants. Moreover, the denture base positioning system may position the denture base in substantially the same position as a surgical guide used to place the implants. In this manner, the denture apparatus may be positioned so that it is mountable to the implants placed according to the surgical guide following their placement in a patient's mouth. In this manner, variations in the placement of the implants arising during the process of installing the implants may be compensated by transferring the actual implant positioning to the denture apparatus when it is positioned by the denture base positioning system.
