If it is correction, you must wear braces. As for whether it's half or full, it depends on your occlusal relationship! If you don't wear braces, you can only make porcelain teeth, which are faster and cheaper than braces, but porcelain teeth are fake after all, their taste is not as good as real teeth, and they also have a certain life. You are still very young, I think it is better to wear braces, which won't damage your teeth!
