What is the best clear aligner?

It is subjective to determine the "best" clear aligner as different aligners may have different strengths and weaknesses. Some popular clear aligners include Invisalign, ClearCorrect, and SmileDirectClub. The choice of the best aligner for a person may depend on factors such as the extent of their dental issue, budget, and personal preference. It is advisable to consult with a licensed dental professional to determine which aligner may be the best fit for you. 

Brealigner transparent aligner sheets are made from Thermoplastic Polyurethane (TPU) material which provides superior flexibility, comfort, and durability compared to traditional clear aligners.
