title: [The effect of active removable orthodontic appliances on the dental enamel].
abstract: It could be demonstrated that enamel defects which are caused by maxillo-facial fixing elements of actively removable implements were reproducible in laboratory experiments. With minimal pressure of the wire bow of 50 grams and 250,000 lift, or individual vertical movements on the enamel surface resulted in a micrometer area of scouring.
