Effect of VPro5 Therapy on Clear Aligner Therapy

Effect of VPro5 Therapy on Clear Aligner Tracking: a Randomized Clinical Trial

The investigators hypothesize that brief, daily application of HFA will increase the efficiency of clear aligner treatment by altering PDL metabolism without increasing pain or discomfort. The investigators will divide subjects into 5 groups changing clear aligners at different time intervals with or without HFA application for 5 minutes/day to assess the effect on: time intervals between aligners, cytokine activity, and pain perception.

Inclusion Criteria:

1. Subject must be 18 - 45 years of age
2. Subject is willing and able to comply with all study procedures and sign Informed consent/HIPAA forms
3. Subject must have complete adult dentition (excluding third molars)
4. Subjects must have class I malocclusion or mild class II/III malocclusions
5. Subject is at least one month into aligner treatment.
6. Subject has history of and current healthy oral hygiene (PD is<4mm, GI<1, and PI=1)

Exclusion Criteria:

1. Subjects who have received periodontal treatment in the previous 6 months
2. Subjects who are taking medication that could affect the level of inflammation, such as chronic antibiotics, phenytoin, cyclosporin, ant-inflammatory drugs, systemic corticosteroids, or calcium channel blockers.
3. Subjects missing adult teeth (except the 3rd molars) or with severe class II or class III malocclusion.
4. Subjects with skeletal class I but extreme dental malocclusion
5. Severe crowding that require extraction
6. More than 4 mm positive overjet and more than 2 mm negative overjet

11. Smoking
12. Vulnerable subjects per IRB definitions
13. Subjects with current caries
14. Subjects that require interproximal reduction or attachments during the study period
15. Subjects who are non-compliant regarding aligner wear or VPro5 recommended daily usage
