The present study was carried out to evaluate the effects of early treatment of Class II Division 1 malocclusion by modified Teuscher activator with lip bumper.
The patients were selected to manage with modified Teuscher activator with lip bumper [Figure 1] and were followed for (13.
In addition to the lip bumper inserted into the headgear tube placed between the maxillary and mandibular teeth in the premolars area.
The aim of current study was to evaluate the skeletal and dentoalveolar changes on cases with Class II Division 1 relationship due to mandibular retrognathism treated by modified Teuscher activator with lip bumper.
In addition, the lip bumper force exerted by labial muscles.
This change in the lower incisors might be due to the use of lip bumper with Teuscher activator combined that might break the muscular equilibrium zone and enhanced the proclination of lower incisors.
Perioral forces and dental changes resulting from mandibular lip bumper treatment.
En este caso, la terapia consiste en un lip bumper flexible (American Orthodontic) que fue disenado en Estados Unidos por Marcel Korn (18) y que implementamos como mantenedor de espacio dinamico (figura 3).
