Molar Protraction and Uprighting (2nd Molar Protraction in the 1st Molar Missing Site and Uprighting an Impacted 3rd Molar)

Abstract

Recently, with the help of TADs (temporary anchorage devices), substantial 2nd molar protraction has become possible in case of missing posterior teeth. Total 260 cases of U-6 (Upper 1st molar missing), L-6 (Lower 1st molar missing) and L-E (Lower E extraction with the 2nd molar missing, E: deciduous 2nd molar) were finished. After 2nd molar protraction, even a horizontally-impacted 3rd molar can be uprighted. This treatment will become very good treatment modality, replacing implants and bridges in cases of missing posterior teeth.
