High-Frequency Acceleration: Therapeutic Tool to Preserve Bone following Tooth Extractions

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Oral and Maxillofacial Surgery

Background:

• Alveolar bone loss post-extraction is a significant clinical challenge with no current long-term preservation solutions.
• Previous research indicated high-frequency acceleration (HFA) stimulates osteogenesis in healthy bone.
• The efficacy of HFA in preserving bone after extraction and its impact on wound healing remained uninvestigated.

Purpose of the Study:

• To investigate the effect of high-frequency acceleration (HFA) on alveolar bone loss following tooth extraction.
• To assess the rate of bone formation and preservation at the extraction site using HFA.
• To evaluate the safety and osteogenic potential of HFA in a post-extraction model.

Main Methods:

• Eighty-five rats underwent maxillary third molar extraction, divided into control, static load, and HFA groups.
• HFA was applied for 5 minutes daily to the HFA group; a static load was applied to the static group.
• Bone analysis utilized fluorescence microscopy, micro-computed tomography, histology, and molecular analyses over 56 days.

Main Results:

• HFA significantly increased bone volume by 44% compared to static load, preserving alveolar bone height and width long-term.
• Osteogenic marker expression and intramembranous bone formation were upregulated with HFA.
• Osteoclastic markers, bone resorption, and inflammatory markers were decreased, indicating enhanced healing and reduced inflammation.

Conclusions:

• High-frequency acceleration (HFA) is a safe, noninvasive treatment that effectively prevents alveolar bone loss after tooth extraction.
• HFA promotes bone regeneration and accelerates healing by modulating bone remodeling and inflammatory pathways.
• This technique holds promise for improving outcomes in dental procedures involving tooth extraction.
