Integrated Surgical Plaque With Movable Skeletal Anchorage for Jaw Fixation

Solution Overview

Problem

Existing orthognathic surgery methods face challenges in achieving stable postoperative occlusion due to limited anatomic opportunities for plaque placement, leading to extra trauma, cost, and unpredictable mandibular positioning, especially when skeletal anchorage systems are not used.

Innovation Solution

A surgical plaque designed as both a fixation and orthodontic anchor, featuring a vertical extension and a linearly movable carrier element with hooks, allowing precise skeletal anchorage and force application adjustment post-surgery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate plaques are used for fixation and orthodontic anchorage, then fixation stability is improved, but device complexity and patient trauma increase

Engineering Contradiction:

Improvefixation stabilityVSAvoidnumber of plaques and screws

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines fixation plaque and orthodontic anchor plaque into a single integrated surgical plaque structure. The surgical plaque includes a main body with vertical extensions that serve both fixation functions (securing bone segments) and orthodontic anchorage functions (providing attachment points for orthodontic appliances), thereby reducing the total number of components needed while maintaining both fixation stability and orthodontic functionality

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The surgical plaque is designed as a multi-functional device that simultaneously performs fixation of separated bone parts and provides skeletal anchorage for orthodontic treatment. The structure includes fixation portions for securing bone segments and carrier elements with hooks for orthodontic force application, allowing one device to fulfill multiple functions that previously required separate components

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple separate plaques are used for fixation and orthodontic anchorage, then fixation stability is improved, but ease of operation deteriorates due to additional anesthesia requirements

Engineering Contradiction:

Improvefixation stabilityVSAvoidsurgical procedure simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent combines fixation plaque and orthodontic anchor plaque into a single integrated surgical plaque structure. The surgical plaque includes a main body with vertical extensions that serve both fixation functions (securing bone segments) and orthodontic anchorage functions (providing attachment points for orthodontic appliances), thereby reducing the total number of components needed while maintaining both fixation stability and orthodontic functionality

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The surgical plaque is designed to be prepared and positioned during the initial orthognathic surgery procedure. The integrated structure allows both fixation and orthodontic anchorage to be established in one surgical session, eliminating the need for subsequent separate surgical interventions and additional anesthesia administrations

Inventive Principle:

Principle #10Preliminary action

3Reliability

If plaques are placed in limited anatomic regions, then fixation function is achieved, but adaptability deteriorates due to restricted positioning options

Engineering Contradiction:

Improvefixation functionVSAvoidplaque placement flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The surgical plaque is divided into distinct functional segments: a main body portion for fixation and vertical extension portions for orthodontic anchorage. This segmentation allows each part to be optimized for its specific function while the overall structure maintains adaptability to different anatomical configurations and surgical requirements

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The surgical plaque incorporates movable carrier elements that can be adjusted along the vertical extensions. This dynamic capability allows the orthodontic anchorage points to be repositioned as needed during treatment, providing adaptability to different orthodontic force application requirements while maintaining stable fixation through the integrated structure

Inventive Principle:

Principle #15Dynamics

AI summary

At least one surgical plaque is provided, which has at least one fixation plaque so as to fix the separated bone parts of the lower and upper jaws in orthognathic surgery. Accordingly, its novelty is to include the following: at least one vertical extension that is connected from one side of said fixation plaque so as to fix the broken parts of 1st mandibula, and at least one carrier element provided to move linearly on said vertical extension so as to provide skeletal anchorage.
