The development of lingual invisalign has brought an additional option to adults seeking dental health and a beautiful smile. Traditional braces have been developed over a very long history and have become an excellent tool for restoring a normal bite to the teeth. However, when adults seek orthodontics, the aesthetic impact of having braces affixed to their teeth, the disruption of eating at social gatherings, and the impact on family life have caused many adults to abandon orthodontics, making aesthetic appearance and an ideal bite an unattainable goal. Lingual braces allow adults to correct without any concerns due to their invisibility, lack of irritation to the lips, and the ability to obtain a beautiful and healthy bite without any sound. However, lingual braces must be made individually for each tooth, and the materials need to contain gold to make them more bio-compatible, so the materials are expensive. In addition, lingual braces are difficult to operate and the treatment cost is relatively high, so the orthodontic cost for patients is relatively high. In addition, lingual braces can have an impact on the clarity of speech during the first 2 to 3 weeks of treatment, so patients need to be prepared.
