I was wondering if the people here might be able to figure something out.
When I was in middle school, in the late '90's, a few of the kids who had braces had a different type of bracket than any of the other kids or myself. Since it was just a handful of kids who had them, I'm guessing it was a single orthodontist in the area who used them. I have never seen this type of bracket in any of the photos or videos on the internet.
They were taller than they were wide (they were pretty narrow), and the archwire ran through the very top of the bracket. There was another slot that ran through the middle of the bracket, however I only ever saw one of the kids with these brackets have a second archwire running through this slot (they had two archwires at the same time, one at the top of the brackets, and the other through the middle).
Looking through my old yearbooks, there was one picture where you could see that they weren't your "normal" brackets:

Has anyone else seen these, know what they are, and/or seen any clearer pictures or videos of them online? At this point, I would assume my mind was playing tricks on me if not for the fact I was able to find the photo in my yearbook.
