Which parts of braces are the most interesting (or fascinating) for you?
In case of fixed braces: Is it the brackets, the molar bands, the archwires, additional wires, elastics? What region do you consider as most interesting? The upper or lower jaw, the front part or the teeth at the side? Or altogehter?
In case of removable braces and hawley retainers: The upper or lower jaw? The plastic or the wires? The labial bow or whatelse? Perhaps the srews?
In case of headgear? The inner bow, the outer bow, the point where both meet, the parts around the neck or head?
And of course: Which kind of braces do you like most?
In my opinion a part of fixed braces to be worth seeing is the brackets on the lower jaw's front teeth. The lower front teeth are narrow and therefore there are many brackets near to each other!
Nevertheless I like all kind of braces, but fixed braces less and retainers more. I think it's because they are not so common.
