Predictability of clear aligners in achieving planned dental arch expansion during mixed dentition: a systematic review and meta-analysis

Key Points

The aim is to evaluate the effectiveness of clear aligners for dental arch expansion in mixed dentition.
Systematic review of studies using Invisalign First for arch expansion
Meta-analysis to quantify predictability
Focus on mandibular arch and anterior teeth outcomes
Invisalign First shows modest to moderate predictability for arch expansion
Particularly effective in the mandibular arch and anterior teeth
Limited effectiveness noted in the posterior maxilla

Abstract

Invisalign First demonstrates modest to moderate predictability for dental arch expansion in mixed dentition, particularly in the mandibular arch and anterior teeth, though limitations persist in the posterior maxilla.
