Lecture Description
The esthetic appeal and convenience of clear aligners have made them increasingly popular among patients of all ages. However, as with any treatment modality, clear aligner has its own unique set of advantages and limitations. Innovations in clear aligner have been driven by advances in technology and material science. Computer-aided design and manufacturing (CAD/CAM) technology has enabled the production of aligners that are highly precise and customized to each patient's individual needs. In addition, the use of digital simulations has enabled the creation of virtual treatment plans that provide a realistic preview of the outcome and facilitate efficient treatment planning. Despite these technological innovations, clear aligner still has certain limitations. One of the major limitations is its ambiguous biomechanics for precise tooth movement. Another limitation is the need for patient compliance, as the success of clear aligner depends on the patient wearing the aligners for the recommended amount of time each day. Non-compliance can result in treatment delays, increased treatment time, and compromised treatment outcomes. To address these limitations, various strategies have been explored such as the use of attachments or auxiliaries (TADs, elastics, Maxillary expanders) to enhance the aligner's control on the tooth and enable more precise tooth movements. Digital simulations have also been used to predict treatment outcomes and plan treatment strategies that are more effective and efficient. The development of new materials such as smart materials that can respond to external stimuli such as temperature or light to exert force on the teeth may also hold promise for improving the effectiveness of clear aligner. In conclusion, clear aligner has undergone significant technological innovations since its inception, and its popularity as an orthodontic treatment option continues to grow. However, the limitations of clear aligner in treating complex cases and achieving patient compliance need to be addressed.
