Brief summary

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?

Detailed description

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

Design outcomes

Primary

MeasureTime frameDescription
Tooth movementAt the end of study completion, an average of 10 months.Tooth movement in the three planes of space measured millimetrically and with degrees, depending on the type of tooth movement

Secondary

MeasureTime frameDescription
Patient discomfort / painEach patient visit, through study completion, an average of 10 monthsRate of Patient discomfort using the visual assessment scale
Appliance defectsEach patient visit, through study completion, an average of 10 monthsRate of Breakage or cracking of the aligners
Patient complianceEach patient visit, through study completion, an average of 10 monthsIndice of Patient compliance evaluated with a questionnaire
Chair and treatment timeEach patient visit, through study completion, an average of 10 months .The amount of time the patient spends on the dental chair at each visit measured in minutes; and treatment length in months
