Solution Overview

Problem

Traditional surgical guides for dental implantation limit the drilling depth and accuracy due to space constraints, reducing the benefits of guided implantology and requiring longer implant insertion for stability, which can compromise the procedure's precision and safety.

Innovation Solution

A surgical guide with strategically positioned sleeves allows for increased drilling depth and improved irrigation, enabling more precise and efficient osteotomy by accommodating larger drill components and facilitating deeper implant placement while maintaining orientation accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a traditional surgical guide is used to guide osteotomy, then the orientation accuracy is improved, but the drilling depth is limited due to space constraints

Engineering Contradiction:
Improveorientation accuracyVSAvoiddrilling depth
Core Design Contradiction:
Measurement precisionVSLength of moving object

Solution Approach 1:

The surgical guide transitions from a traditional single-sided template to a bilateral structure with sleeves extending through the guide body. This dimensional change allows drills to pass through the guide from both sides, effectively doubling the available drilling depth while maintaining orientation guidance through the sleeve structures.

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

Solution Approach 2:

The surgical guide is segmented into multiple functional components: a guide body, bilateral sleeves, and positioning elements. This segmentation allows each component to serve its specific function - the sleeves provide orientation guidance while the guide body provides structural support, enabling deeper drilling without compromising accuracy.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If a traditional surgical guide is used, then orientation guidance is provided, but the execution time is increased due to multiple passages

Engineering Contradiction:
Improveorientation guidanceVSAvoidexecution time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The bilateral sleeve structure divides the drilling operation into two independent passages, allowing the surgeon to complete both osteotomies efficiently in sequence without removing the guide, thereby reducing total execution time while maintaining orientation accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The surgical guide remains in place throughout the entire osteotomy process, providing continuous orientation guidance. The bilateral design allows both drilling operations to be performed in one continuous workflow without removing or repositioning the guide, eliminating setup time and maintaining precision throughout.

Inventive Principle:
Principle #20Continuity of useful action

3Measurement precision

If a traditional surgical guide is used, then guidance is provided, but irrigation of the alveolus is insufficient

Engineering Contradiction:
Improveguidance accuracyVSAvoidirrigation volume
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The irrigation system transitions from a single-sided approach to a bilateral configuration, with irrigation channels extending through both sides of the guide body. This allows cooling and lubrication fluid to reach the osteotomy site from multiple directions, significantly improving irrigation effectiveness while maintaining guidance accuracy.

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

4Length of moving object

If the surgical guide is removed to increase drilling depth, then drilling depth is improved, but orientation accuracy is lost

Engineering Contradiction:
Improvedrilling depthVSAvoidorientation accuracy
Core Design Contradiction:
Length of moving objectVSMeasurement precision

Solution Approach 1:

Instead of removing the guide to achieve deeper drilling, the design extends the guidance structure bilaterally through the guide body. The sleeves continue to provide orientation guidance throughout the entire drilling path, allowing maximum depth achievement without compromising accuracy.

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

Solution Approach 2:

The bilateral sleeves serve multiple functions simultaneously: they provide orientation guidance, define the drilling path, and allow deep osteotomy. This multi-functionality eliminates the need to choose between depth and accuracy, as both are achieved together through the same structural elements.

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

AI summary

A surgical guide system for dental implantology has a plate (10) provided with a guide sleeve (2) delimiting a through hole with an axis oriented to a predetermined direction. A drill (4) for osteotomy has a spindle connected to a handpiece with drilling portion (41), the drill (4) being for association with the guide sleeve (2) during osteotomy. The diameter (d41) of the drilling head portion (41) is larger than the inner diameter (d2) of the guide sleeve (2) and the spindle is of smaller diameter, such that the association of the drill (4) to any of the guide sleeves (2) can be performed only by inserting the spindle through a gingival side of the sleeves. Upon association of the drill with the sleeve, the drilling head (41) protrudes from the gingival side (2G) thereof. The surgical guide has a void (100) accommodating the drilling head (41) of the drill.
