There are many different models of braces. We have already discussed that braces can be conventional or self-ligating, and that they can be made from different materials such as metal, ceramic and sapphire. It isn't the braces that carry out the treatment. The optimal result of orthodontic treatment depends on the orthodontist's abilities, skills and experience. Detailed, carefully gathered initial information about the patient, a well-constructed treatment plan and its precise technical execution are what guarantee the perfect smile. That is why you can't say there are ‘best’ braces. Different models of braces can have their advantages and disadvantages. And the best braces are the ones your orthodontist knows best.
This answer is for general information. Your own case needs an examination by an orthodontist.
