The present invention relates to a healing abutment and an implant having the same, and more particularly, to a healing abutment and an implant provided with the healing abutment which can fasten an impression coping for the impression taking directly.

Implant (implant) refers to a substitute that is originally restored when human tissue is lost, but in the dentist refers to the implantation of artificial teeth. In order to replace the lost root (root), a tooth root made of titanium (titanium), which is not rejected by the human body, is planted in the alveolar bone where the tooth falls out, and the artificial tooth is fixed to restore the function of the tooth.

In the case of general prosthetics or dentures, the surrounding teeth and bones are damaged after time, but the implants do not damage the surrounding dental tissues, and they have the advantage that they can be used semi-permanently because they have the same function or shape as natural teeth.

Implants also enhance the function of dentures and improve the esthetic aspects of dental prosthetic restorations, as well as in single missing restorations. Furthermore, it disperses excessive stress on surrounding supportive bone tissue and helps stabilize teeth.
