Solution Overview

Problem

Existing dental implant surgeries face challenges in bone reduction due to bone resorption, particularly in the anterior region, leading to insufficient space for dental restorations and potential exposure of the dental restoration-gingiva boundary, necessitating precise bone reduction methods and guides.

Innovation Solution

A method and device for designing an implant surgical guide that includes generating virtual implant and bone reduction guide shapes, with a guide rail parallel to the occlusal plane, ensuring bone reduction is performed accurately and efficiently, integrating these guides to facilitate stable prosthesis production, and determining guide drill length compatibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If bone reduction is performed in the anterior region to secure implant space, then sufficient space for dental restoration is achieved, but precision and control of bone reduction become more difficult

Engineering Contradiction:
Improvespace for dental restorationVSAvoidprecision of bone reduction
Core Design Contradiction:
Length of moving objectVSManufacturing precision

Solution Approach 1:

The surgical guide is divided into multiple components: a body portion that contacts the bone surface, a guide portion with guide holes for drill positioning, and a retention portion with clips for securing the guide. This segmentation allows each component to be optimized independently for its specific function while maintaining overall precision during bone reduction

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A virtual surgical guide is first designed and visualized using dental image data (CBCT and intraoral scan) to plan the bone reduction procedure. This virtual model is then used to fabricate a physical surgical guide through 3D printing or CNC machining, allowing the planned reduction path to be precisely replicated during surgery

Inventive Principle:
Principle #26Copying

2Manufacturing precision

If a separate bone reduction guide is used in addition to the implant surgical guide, then bone reduction precision is improved, but device complexity and manufacturing time increase

Engineering Contradiction:
Improvebone reduction precisionVSAvoidguide structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The surgical guide integrates multiple functions into a single unified structure: the body portion provides stable seating on the bone, the guide portion contains guide holes for both implant placement and bone reduction, and the retention portion secures the guide during surgery. This integration eliminates the need for separate guides while maintaining precision

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The guide portion of the surgical guide is designed to serve multiple purposes: it guides the implant drill for implant placement and simultaneously guides the bone reduction drill for precise bone reduction. The guide holes are positioned and dimensioned to accommodate different surgical instruments for different procedures, making the single guide structure universally applicable to multiple surgical tasks

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