The goal of this clinical trial is to test the effectiveness of lingual aligners in adults. The main question to answer is: \- Are lingual aligners effective in achieving desired and predicted tooth movements?
The aim of this pilot study is to assess the effectiveness and the accuracy of lingual aligners by evaluating the discrepancy between the predicted and the achieved amounts of tooth movements. Also: * Patient discomfort and pain * Appliance defects * Patient compliance * Chair and treatment time Key inclusion criteria: * Adults older than 18 years old * About to undergo orthodontic treatment Key exclusion criteria: * Patients with tooth extractions or tooth agenesis with space closure * Patients with surface enamel defects * Pregnant patients * Syndromic patients or those with cleft lip and/or palate * Patients with metabolic diseases
