Implication

Systematic review evaluates skeletal effects of bone-anchored and tooth-borne maxillary expanders, suggesting BA expanders yield greater benefits.

Key Points

  • Bone-anchored expanders showed greater immediate changes in nasal width, maxillary width, and sutural expansion compared to tooth-borne expanders.
  • During the first 6 months post-expansion, BA expanders resulted in more favorable skeletal and dentoalveolar effects, particularly in nasal width changes.
  • Analysis included ten studies with empirical support for differences, yet raised concerns about the long-term stability of these outcomes.
  • High heterogeneity and low quality of evidence necessitate caution in interpreting the findings and highlight the need for further research.
