Indications, limitations, and outcomes of clear aligners in orthodontic treatment

Clear aligners have gained popularity in orthodontic treatment as a comfortable and aesthetically pleasing alternative to traditional braces. The use of clear aligners has increased due to their advantages, including improved aesthetics, easy removability, and minimal soft tissue irritation. The treatment process involves sequential aligners custom-made for each patient, using computer-aided design and manufacturing technology. Clear aligners employ controlled forces to gradually move teeth into proper alignment. However, clear aligners have limitations, such as the need for patient compliance and their effectiveness in addressing complex malocclusions. Clinical considerations include thorough assessment, regular follow-up visits, and patient education. Treatment outcomes vary depending on the specific malocclusion characteristics. Clear aligners have demonstrated benefits in treating mild malocclusions, spacing issues, and certain types of malocclusion corrections. Treatment duration may be shorter compared to fixed appliances in mild cases. Stability and periodontal health can be influenced by clear aligner therapy, which has effects on plaque levels and gingival inflammation. Root resorption is a concern, but aligners have shown a lower prevalence compared to fixed appliances. Compliance, eruption of permanent teeth, and limitations in visualizing hard and soft tissues are important considerations. Overall, clear aligners offer an aesthetic orthodontic treatment option for a variety of dental abnormalities and mild to moderate orthodontic issues.
