The Effectiveness of Functional Clear Aligners for Class II Correction in Growing Patients: A Systematic Review and Meta-Analysis.

Summary: For kids with "buck teeth" or a small lower jaw, the usual fix involves bulky metal braces or blocky appliances that can be uncomfortable. Doctors call this a "Class II" problem. A new study looked at 21 different medical reports to see if clear plastic aligners—like the invisible trays many adults use—can fix these jaw problems in growing children just as well as the old metal gear. The results were very promising! The clear aligners successfully helped the lower jaw grow forward and straightened the teeth, working just about as well as the traditional appliances. While doctors still want to do more long-term research, these clear aligners look like a great, less visible option for kids needing bite correction.
