Study Summary

This study is being done to compare conventional clear aligners with 3D printed clear aligners to assess if there is any significant difference between the microbial colonization of these appliances. The 3D printed aligner material and conventional aligner materials are being used for investigational purposes and have been approved for their use in fabricating clear aligners for orthodontic tooth movement, but not for the purposes of our study, which is for the fabrication of clear passive aligners to assess microbial colonization.

Primary Outcome

Assessed using a swab to the tooth surface (three times, once for each aligner)

Interventions

  • DEVICE Thermoformed clear aligner
  • DEVICE 3D printed clear aligner TC-85
  • DEVICE 3D printed clear aligner TA-28
