Each aligner in a sequence is manufactured to be slightly different from the patient’s current tooth position, creating a mechanical environment that stretches the periodontal ligament. When the aligner is worn, this biological response triggers bone remodeling, allowing the tooth to gradually shift into the desired position precisely defined by the digital treatment plan. While aligners are an excellent option for teenagers and adults seeking a discreet treatment method, the success of the movement relies heavily on the precision of the digital plan and the system’s ability to control complex root movements. This is why proprietary, customized systems offer distinct clinical advantages over generic, outsourced alternatives.
