Clear aligner set and orthodontic treatment method considering resilience of human body

A clear aligner set considering resilience of a human body, the clear aligner set comprising:

• at least one first clear aligner having a first orthodontic space therein, formed of a first transparent material, having a first restoring force to apply a first pressing force to teeth for a first wearing time a day during a first period in consideration of the resilience of a human body, and primarily wearable by an orthodontic patient;
• at least one second clear aligner having a second orthodontic space therein, formed of a second transparent material, having a second restoring force greater than the first restoring force to apply a second pressing force greater than the first pressing force to the teeth for a second wearing time a day during a second period in consideration of the resilience of the human body, and secondarily wearable by the orthodontic patient;
• at least one third clear aligner having a third orthodontic space therein, formed of a third transparent material, having a third restoring force greater than the second restoring force to apply a third pressing force greater than the second pressing force to the teeth for a third wearing time a day during a third period in consideration of the resilience of the human body, and tertiarily wearable by the orthodontic patient;
• wherein the first orthodontic space is a space corresponding to the teeth;
• wherein the second orthodontic space is a space larger than the first orthodontic space to accommodate the at least one first clear aligner therein;
• and
• wherein the third orthodontic space is a space larger than the second orthodontic space to accommodate the at least one second clear aligner therein.
