- 7. fixing wax strips which stand in an upright position on a conical rubber base, fixing the wax strips with iron sleeve and injecting high-temperature embedding material into the iron sleeve to cover the artificial tooth.
- 8. heating the iron sleeve which surrounds the wax strips by putting it into a dewaxing oven.
- 9. when the iron sleeve is heated to a predetermined temperature, using propane oxygen torch to melt down the denture alloy, using a centrifugal casting machine to inject the melted alloy into the tooth model.
- 10. after the iron sleeve cools down, breaking the embedding material and taking out the metal artificial tooth model, using a sandblasting machine to clean the surface of the metal tooth base.
- 11. forming a metal base of the ceramic artificial tooth by grinding the metal tooth base.
- 12. treating the metal tooth base with sandblasting, ultrasound and high temperature steam cleaning, coating it with an opaque layer and heating it putting into an electromagnetic oven, coating with a second opaque layer after the metal tooth base cools down, then heating by putting it back into the electromagnetic oven again.
- 13. after the metal tooth base cools down, piling ceramic powder onto the metal tooth base, the ceramic powder includes the dentin color ceramic powder forming the body, the enamel color ceramic powder, and the translucent ceramic powder, then heating the metal tooth base by putting it into the electromagnetic oven to form the ceramic artificial tooth.
- 14. after forming the ceramic artificial tooth, grinding, cutting and trimming the ceramic artificial tooth to fit it into the plaster model.
- 15. glazing and putting into the electromagnetic oven again.
- 16. after the ceramic tooth cools down, polishing the ceramic tooth and cleaning the ceramic tooth and the plaster model with high pressure steam.
- In general, the conventional tooth making process is time consuming and will suffer the problem of thermal expansion and contraction, and therefore, the resultant tooth is likely to be deformed.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
- The primary objective of the present invention is to provide an ultrasonic tooth making machine which offers the advantages of quick tooth making, high precision size, resistant to deformation and high efficiency of powder waste and scraps removing.
