| Abstract |
|
In the mixed dentition, many children have mild crowding of anterior dentition on the mandibular arch and mesial tilting of mandibular molar. Lip bumper have been used to gain arch length for the alignment of mild to moderate crowded dental arches. As such, they may provide an alternative to extraction therapy. The claimed therapeutic effect of the lip bumper is bodily forward incisor movement, flaring of the lower incisors, and distal tipping of the molar. The dental changes can be attributed to removal of lip pressure on the lower anterior dentition and the distal forces exerted at the molar abutment. The purpose of this study is to show more easily method of treatment for mild anterior crowding of mandible. |
