Inman aligner
It shifts the first four front teeth in the fastest and cheapest way than other devices. This method is not invasive and does not require grinding of healthy teeth. The duration of the therapy is individual, but in any way shorter than the other therapies (6-16 weeks). The big advantage of Inman aligners is their relatively low price. The disadvantage of Inman aligners is a very narrow spectre of teeth anomalies which can be treated, the bulkiness of the device which often disturbs speech and the preciseness of the final results (sometimes it is difficult to achieve a 100% final alignment of teeth).
