Technical Field

The invention relates to the field of dental implants, in particular to a modular layered dental implant.

Background

The dental implant surgery generally comprises drilling an implant hole in an alveolar bone of a missing site of a patient's tooth, implanting an implant into the implant hole, and fixing and installing a prosthetic denture on the implant. After the implant is implanted into the implant hole of the alveolar bone, if inflammation occurs at a contact position of an edge of the implant hole of the alveolar bone and an upper end of the implant, bone loss around the implant may be caused, thereby causing the implant to be loosened and to fail, and thus, it is necessary to treat the inflamed portion of the alveolar bone. However, the current treatment scheme is to extract the dental implant integrally, which is costly and risky, and the extraction process requires cutting off a large amount of alveolar bone, resulting in secondary damage to the alveolar bone. In addition, the traditional dental implant has fixed model and specification, and cannot perform personalized repair according to the condition of the alveolar bone of a patient.
