As a result of the increasing demands to enhance esthetics among the different community populations, many efforts have focused on innovating other substitutes to increase patients’ satisfaction and to obtain better clinical outcomes. Among the variously proposed candidates, clear aligners are now commonly reported and used within clinical settings. Additionally, technological advances are also significant in this field. In this literature review, we aim to discuss the indications, advantages, disadvantages and the effectiveness of Invisalign braces. Typically, the ideal patients that are indicated to receive Invisalign systems are adult patients with either incisor flaring, spacing, crowding, infra- or supra-positions. Although time-consuming, Invisalign systems are reported with reduced adverse events and toxic reactions with the gingival tissue, minimizing the risk of developing periodontal diseases. However, Although Invisalign modalities are associated with fewer adverse events and reduced gingival inflammation and plaque formation. Previous studies have demonstrated that the outcomes might be similar when patients with fixed appliances are educated about properly conducting oral hygienes. Besides, improved healing of the periodontal ligament was also reported with the modality. Therefore, better clinical outcomes are expected with the modality. Furthermore, studies have also demonstrated similar effectiveness between Invisalign and fixed appliances while the most accurately obtained tooth movements with Invisalign might include retrusion, rotations, fan-type expansions and protrusions. Further investigations are urgently needed for further validation of the current evidence.
