LZQ often produces non-standard, special-shaped, high precision products which are difficult to machine in medium and big batch, but rarely in a small number for single dimension standard ones, because the cost of jig, fixture, mold, and grinding wheel is quite high, and if without the mold, it is difficult to make an excellent item. However, it depends on the type and dimension of the required products. Besides, in our company, the cost of standard products and that of the non-standard is similar.
In orthodontics, small diameter dental implants, referred to as Temporary Anchorage Devices (or TADs) can help enamel movement through growing anchor factors from which forces can be generated. For enamel to move, a force should be utilized to them in the path of the favored movement. The force stimulates cells in the periodontal ligament to cause bone remodeling, casting off the bone in the course of the journey of the enamel and including it to the house created. In order to generate a pressure on a tooth, an anchor factor (something that will no longer move) is needed. Since implants do now not have a periodontal ligament, and bone remodeling will no longer be encouraged when anxiety is applied, they are ideal anchor factors in orthodontics. Typically, implants designed for the orthodontic motion are small and do no longer fully osseointegrate, allowing convenient elimination following treatment
