After that, the implant fixture is implanted in the alveolar bone using the surgical handpiece, and then the fixture mount is removed from the implant. Then tighten the cover screw on the top of the implant to seal the implant and complete the first operation. The cover screw serves to prevent bacteria and foreign bodies remaining in the oral cavity from invading the implant while waiting for the implant to fuse. The bone fusion period varies somewhat depending on the patient's bone and implant location, but usually takes three to five months.

Then, the gums were opened by a secondary operation to expose the covering screws, after which the degree of bone fusion of the implant was confirmed, and the covering screws were removed. Then, in order to prevent the gum from covering the space where the artificial tooth is to be implanted and to form an aesthetic gum, a healing cap is fastened to the upper part of the implant, etc. pending reservation period. Finally, the healing cap is removed after confirming that the esthetic gingiva is formed, and the impression cap is fastened to the upper part of the implant to make a denture.
