Solution Overview

Problem

Current dental surgical systems lack an efficient method for achieving a flush, coplanar bone surface during bone reduction procedures, which is crucial for securing dental prosthetics, as they often require manual precision and may not provide adequate structural or visual guidance for bur instruments.

Innovation Solution

A bone foundation guide with a bur guide attachment that allows for precise alignment and movement of bur instruments along a horizontal plane, ensuring a flush bone surface is achieved, and a bur guide that supports the bur instrument to facilitate accurate bone cutting and reduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual bone reduction procedures are used, then surgeons have flexibility in operation, but precision and efficiency in achieving flush bone surface deteriorates

Engineering Contradiction:

Improveprecision in achieving flush bone surfaceVSAvoidcomplexity of surgical guidance system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a bur guide attachment as an intermediary device between the surgeon's manual operation and the bone surface. This attachment provides structural guidance and visual references (horizontal plane indicators) that mediate the cutting process, enabling precise achievement of flush bone surfaces without requiring complex automated surgical systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The bur guide attachment is designed to be self-aligning and self-guiding during the bone reduction process. The horizontal plane indicators and guide structure automatically provide reference planes that guide the bur instrument, allowing the system to self-correct and maintain precision without requiring complex external control systems or highly skilled manual operation.

Inventive Principle:

Principle #25Self-service

2Productivity

If manual bone reduction procedures are used, then surgeons can adapt to varying anatomical structures, but efficiency and time consumption deteriorates

Engineering Contradiction:

Improveefficiency of bone reduction procedureVSAvoidtime to achieve flush bone surface

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The bur guide attachment is pre-configured with horizontal plane indicators and guide structures that establish reference planes before the bone reduction begins. This preliminary setup provides immediate visual and physical guidance during the procedure, eliminating the need for time-consuming measurements and adjustments during surgery, thereby significantly improving efficiency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The guide attachment acts as a mediator that translates the surgeon's adaptive manual control into efficient, precise bone reduction. By providing pre-established reference planes and continuous visual feedback, it enables rapid bone removal while maintaining precision, reducing the time required to achieve flush surfaces compared to purely manual methods.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Manufacturing precision

If structural guidance for bur instruments is added, then precision in bone cutting improves, but device complexity increases

Engineering Contradiction:

Improveprecision of bone cuttingVSAvoidcomplexity of bur guide attachment

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The bur guide attachment applies structural guidance only where needed - at the interface between the bur instrument and the bone surface. Rather than providing comprehensive structural support throughout the entire surgical system, the attachment focuses guidance elements (horizontal plane indicators, guide slots) locally at the cutting zone, maintaining simplicity while achieving precision.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The bur guide attachment is designed as a multi-functional device that combines several functions in a single simple structure: it provides structural guidance for the bur instrument, visual references for the horizontal plane, and physical constraints for cutting depth. This consolidation of multiple functions into one attachment avoids the need for multiple separate complex devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An apparatus includes a first guide and a second guide. The first guide includes an arcuate horizontal body portion. A rear surface of the horizontal body portion is configured to closely mate with a front-facing bone structure of an alveolar arch of a patient. The second guide includes a body and a coupling member. The body defines a passageway that is configured to receive a bone reducing instrument. The coupling member is configured to mate with the horizontal body portion of the first guide. The body and the coupling member are configured to position the passageway along a second horizontal plane that is parallel with the first horizontal plane. The coupling member is configured to enable the second guide to move relative to the first guide along the second horizontal plane and thereby guide the bone reducing instrument along the second horizontal plane.
