How to use and how does the VIBE II work?

Usage protocol

The ideal protocol for use is to utilise twice per day for 8 minutes each time: 2 minutes on each side of the mouth using the posterior nodular attachment (total 4 minutes).

1 minute on the premolars of each side with the EPS vibratory attachment (total 2 minutes) and then 2 minutes using the anterior nodular attachment (total 2 minutes). This protocol is integrated with use during the day at every aligner reinsertion using the Munchies®️ EPS device.

Additional seating in areas that may be lagging can be achieved by using the specific grooved anterior attachments as directed.

How does the VIBE II work?

Orthodontic tooth movement was assessed when HFA parameters, frequency, acceleration, duration of exposure, and direct or indirect application were varied. Researchers found that HFA treatment significantly enhances the inflammation-dependent catabolic cascade during orthodontic tooth movement.

HFA treatment increases inflammatory mediators and osteoclastogenesis, and decreased alveolar bone density during orthodontic tooth movement. Each of the HFA variables produced significant changes in the rate of tooth movement and the effect was PDL-dependent.

Thirty patients with initial Class I skeletal relationships, initial minimum-moderate crowding (3–5 mm), treated to completion with clear aligners and adjunctive high-frequency vibration, (HFV group) or no vibration, (Control group) were evaluated.

The patients were instructed to change aligners as soon as they become loose. Changes in bone density associated with orthodontic treatment were evaluated using i-CAT cone-beam computed tomography (CBCT) and InVivo Anatomage®️ software to quantify density using Hounsfield units (HU) between treated teeth in 10 different regions. HU values were averaged and compared against baseline (T1) and between the groups at initiation of retention (T2).

RESULTS: The average time for aligner change was 5.2 days in the HFA group, and 8.7 days in the control group . There was significant T1 to T2 increase of HU values in the upper arch (P = 0.0001) and the lower arch (P = 0.008) in the HFA group. There was no significant change in average HU values in the upper (P = 0.83) or lower arches (P = 0.33) in the control group. The intergroup comparison revealed a significant difference in the upper, (P = 0.0001) and lower arches (P = 0.007).

CONCLUSION: High-frequency acceleration devices, adjunctive to clear aligners, allowed early aligner changes that led to shorter treatment time in minimum-moderate crowded cases.
