  • Premolar extraction is an effective treatment for patients with bimaxillary dentoalveolar protrusion, particularly when using clear aligners (CAs) which close extraction spaces but can cause unwanted tooth movements, especially in cases where 2nd premolars are removed.
  • This study analyzed two models of bimaxillary dentoalveolar protrusion to understand the effects of extracting either the 1st or 2nd premolars on tooth tipping and anchorage loss using finite element analysis.
  • Results indicated that extracting 1st premolars resulted in more significant changes in tooth angulation and a greater tendency for distal tipping compared to 2nd premolars, with the maxillary arch showing more mesial tipping
