Influence of lower anterior crowding on the predictability of mandibular tooth movement in Invisalign therapy: a retrospective cohort analysis

Key Points

• Mandibular tooth movement predictability is significantly reduced in cases of dental crowding, complicating treatment outcomes.
• Clinically, a routine overcorrection approach may enhance results for patients undergoing clear aligner therapy with crowding.
• Assessment in this analysis involved reviewing the effects of dental crowding on treatment outcomes, focusing on clear aligners.
• This work highlights the importance of using additional tools to guide treatment when significant crowding is present, implying potential for improved patient care.
