A system for straightening teeth includes a casting of teeth that is made of a rigid material, and a gum casting made of a flexible material that is joined to the teeth casting. A respective articulating tool for each tooth is provided with a post that is embedded into the tooth. Tooth moving components, accessible through the gum casting, are mounted on each post to selectively provide for left-right, fore-aft, and rotational tooth movements. In its operation, the system involves selectively orienting individual teeth in the teeth casting, to prepare a series of sequentially useable appliances that will straighten teeth in accordance with a pre-planned procedure. |
