FAQ

Which is more effective, clear aligners or fixed braces?

There is no significant difference in most circumstances, but complex cases create a distinction. A systematic review and meta-analysis of 15 trials and 1084 patients reported **no significant difference** in treatment quality or duration in **non-extraction cases**, whereas in **extraction cases**, **fixed appliances provided better treatment quality, attributed to their greater control of tooth movement** [F1]. The review concluded that both can effectively achieve orthodontic goals and that selection should be based on case complexity and patient adherence. It nevertheless reported that between-study heterogeneity and short follow-up periods limited the strength of its conclusions.
