LMHFV Vibration for Alveolar Ridge Vertical Augmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for alveolar bone augmentation, particularly in cases of horizontal bone loss following tooth extraction, face challenges such as bone resorption and the need for additional surgical sites, with no effective application of low magnitude high frequency vibration (LMHFV) for vertical augmentation.
Innovation Solution
The method involves using LMHFV in conjunction with dentin grafts and a membrane to enhance alveolar bone height, where the LMHFV device applies vibrations to the alveolar ridge to stimulate bone growth, with the graft material being packed onto the ridge and covered with a membrane to facilitate vertical augmentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grafts are used to fill the extraction socket, then bone regeneration is promoted, but horizontal bone loss occurs and neighboring teeth are destabilized
Solution Approach 1:
The patent applies low magnitude high frequency vibration (LMHFV) to the alveolar ridge to stimulate vertical bone growth and prevent horizontal bone loss. The vibration mechanism activates osteogenic pathways and enhances graft material integration, transforming the traditional static grafting approach into a dynamic treatment that actively promotes bone regeneration while preventing the harmful horizontal bone loss that occurs with conventional methods
2Reliability
If hemopoietic marrow grafts are used, then crestal bone gain is achieved, but bone resorption of neighboring tooth roots occurs
Solution Approach 1:
The patent extracts and removes the harmful hemopoietic cells from the graft material, retaining only the beneficial osteogenic components. By separating and eliminating the monoblastic precursors that cause bone resorption, the treatment achieves crestal bone gain without the harmful side effects of neighboring tooth root resorption associated with traditional marrow grafts
Solution Approach 2:
The patent employs a disposable vibration device that can be easily removed and replaced, eliminating the need for complex, long-term surgical implants. This simple, short-term vibration mechanism provides effective bone regeneration without requiring permanent surgical structures, reducing overall treatment complexity and patient burden
3Reliability
If multiple surgeons are involved for harvesting iliac crest marrow, then graft quality is improved, but treatment time and expense increase
Solution Approach 1:
The patent enables the patient's own body to provide the necessary graft material through self-service mechanisms. The vibration device stimulates the patient's alveolar bone to naturally regenerate and provide the necessary structural support, eliminating the need for complex multi-surgeon procedures to harvest and process graft material from the iliac crest
Solution Approach 2:
The patent replaces the complex mechanical system of multi-surgeon graft harvesting and processing with a simple vibration-based mechanism. Instead of requiring surgical extraction, transportation, and processing of marrow grafts, the treatment uses vibrational stimulation to directly activate bone regeneration at the treatment site, dramatically simplifying the overall process

Function Achieved in This Case
This approach reliably achieves extra-alveolar vertical augmentation, promoting better oral health and stabilizing the alveolar ridge, which was not predictably achievable in prior art, with visible augmentation measured in the vertical dimension.

AI summary
A novel method for extra-alveolar vertical augmentation utilizing bone graft and low-magnitude high-frequency vibration. Graft material is placed at an extra-alveolar location along the alveolar ridge. The graft can be used alone or formed into a PRF block to help it maintain volumetric shape during the initial healing process. After insertion into the surgical site, the graft can be covered by a barrier, for example a bioactive amnion/chorion barrier. The flaps are then sutured to attempt to obtain primary closure over the graft and barrier. Low-magnitude high-frequency vibration is applied, resulting vertically augmented alveolar bone.
