What is the difference between Prevent’s custom iMG and boil and bite iMG?

The Prevent custom iMG requires a dental scan of the upper teeth for each user

The Prevent custom iMG requires a dental scan of the upper teeth for each user, while the Prevent boil and bite is a standard off-the-shelf solution which requires a one-minute fitting process for each user to gain a personalized fit. The Prevent custom iMG is most commonly used by elite athletes who are familiar with wearing a custom mouthguard. Community-level athletes frequently wear the Prevent hybrid boil & bite iMG due to ease of implementation and use.
