Good evening sir Sir as the name itself tells it's invisible appliance doing the job of proper alignment of teeth And we have to see if your case is suitable for it and the treatment progress is completely dependent on you as you will be able to remove and place the aligner by yourself once the treatment is started Straightening of the teeth is possible depending on the severity of malocclusion Costing is variable from doctor to doctor and area where you prefer treatment
