Clear aligner therapy is a modern approach to orthodontic treatment that has gained considerable popularity over the years. It involves using clear, removable aligners to straighten misaligned teeth. This method has revolutionised the field of orthodontics, providing patients with a discreet and comfortable alternative to traditional metal braces.Unlike traditional braces that require brackets and wires, clear aligners are made from a clear, durable plastic material that is virtually invisible. They are custom-made for each patient and are designed to gradually shift teeth into their proper position over time. The treatment process typically involves a series of aligners that are changed every few weeks, with each new aligner gradually moving teeth closer to its final alignment.Clear-aligner therapy offers several advantages over traditional braces, including greater comfort, convenience, and flexibility. Since the aligners are removable, patients can eat, drink, brush, and floss normally without any restrictions. Additionally, clear aligners are easy to clean and maintain, making them a popular choice for individuals with busy lifestyles. However, the clear aligners are still under investigation and clinicians are currently comparing them with traditional orthodontic appliances to determine whether they deliver the promised outcome or not.
