Abstract
Objectives: The object of this clinical study was to compare three different aligner systems. The aim was to help the ortho-dontist with choosing an adequate aligner philosophy/therapy system.Materials and methods: This study included 60 randomly chosen patients. Mild to moderate cases were selected, and patients were assigned to three groups of 20 patients each. One group was treated with Invisalign (20 patients), the sec-ond group was treated with CA Clear Aligner and the third group of patients was treated with the Orthocaps aligner sys-tem. In all cases, attachments were used to additionally en-hance the fitting and efficiency of the aligner.Results: All investigated aligner systems achieved the predict-ed goal of the treatment, although with significant differences concerning accuracy, the predicted duration of treatment and the number of refinements. Significant differences were deter-mined, especially regarding the efficiency, duration and cost of treatments.Conclusion: Aligner orthodontics allow for handling difficult treatment cases despite different aligner philosophies, differ-ent materials and different durations of treatment. There were significant differences concerning the envisaged time of treatment. In moderate cases, a significant difference con-cerning duration and costs was determined. IntroductionThere are many orthodontic systems on the market, and it can be difficult for clinicians to choose. The aim of this clinical study was to compare three different aligner systems. The main differences between the systems are described. The study combines a report of 60 treated patients, treated with three currently available systems. Comparisons were made based on factors useful to the clinician, including comfort, cost, and whether the intended treatment goal was reached
