Solution Overview

Problem

Existing dental implant placement methods require bone grafting or invasive procedures due to insufficient bone density, which are traumatic and complex, and alternative solutions like very short implants or zygomatic implants are not universally applicable.

Innovation Solution

A bone biostimulation device with a flexible tip and vibration generator, such as an electric toothbrush handle, is used to stimulate bone growth by transmitting vibrations to the maxillary bone structure, avoiding the need for bone grafting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If bone grafting is performed to improve bone density for implant placement, then the bone structure becomes sufficient for implant fixation, but the procedure becomes heavy and traumatic

Engineering Contradiction:

Improvebone densityVSAvoidtrauma

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent applies mechanical vibration through a vibration generator that transmits oscillations to the maxillary bone structure via a flexible tip. This vibration stimulation promotes bone growth and consolidation without requiring traumatic bone grafting procedures, thereby improving bone density while avoiding the harmful effects of invasive surgery

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent replaces the mechanical bone grafting system with a vibration-based biological stimulation system. Instead of physically adding bone material through grafting, the system uses mechanical vibrations to stimulate the body's natural bone regeneration processes, eliminating the need for traumatic surgical intervention

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If very short and narrow implants are used to avoid bone grafting, then the procedure becomes less invasive and expensive, but the consistency between replaced tooth size and contact surface is compromised

Engineering Contradiction:

ImproveinvasivenessVSAvoidconsistency between tooth size and contact surface

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by using vibration therapy to pre-consolidate and stimulate bone growth in the maxillary ridge before implant placement. This preliminary biological preparation ensures that the bone structure achieves sufficient density and consistency to support standard-sized implants, thereby maintaining implant reliability while avoiding the need for invasive bone grafting

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If zygomatic implants are used to fix implants at a distance from missing teeth, then implant placement becomes possible in resorbed jaws, but the procedure remains very invasive

Engineering Contradiction:

Improveapplicability to resorbed jawsVSAvoidinvasiveness

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses mechanical vibration to stimulate bone consolidation in the maxillary ridge, creating sufficient bone density in resorbed jaws without requiring invasive zygomatic implant placement. The vibration therapy prepares the bone structure to support standard implants locally, eliminating the need for distant zygomatic fixation while maintaining adaptability to resorbed jaw conditions

Inventive Principle:

Principle #18Mechanical vibration

4Ease of manufacture

If dental bridges are used to avoid bone grafting, then the procedure becomes simpler, but the solution requires damaging healthy teeth and has shorter lifespan

Engineering Contradiction:

ImprovesimplicityVSAvoiddamage to healthy teeth

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the dental bridge system with a vibration-based bone stimulation system. Instead of mechanically securing a bridge to healthy teeth, the system uses mechanical vibrations to stimulate bone growth and consolidation, allowing for implant placement without damaging adjacent teeth while maintaining long-term reliability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
