High-frequency vibration relapse case study

HFV Case

Treatment Time: 4 Months

Dr. Thomas Shipley

Patient Info: Teenage Male presented with lower anterior relapse one year post-treatment. He had not worn a retainer for six months and could not get it even half-way on without significant pain. A new scan and costly retreatment seemed like the next course of action, which may have lost the ortho referral of the younger sibling.

Modality: Clear Plastic Retainer


  • Lower Anterior Relapse

Treatment Notes:

  • VPro™ used in-office and patient was able to leave with his retainer seating improved
  • Continued use of VPro 5 minutes per day and the patient’s teeth returned to the same position as when he completed treatment
