A dental implant made of zirconia ceramic-fused-bioactive glass ceramic artificial bone dust and a preparation method therefor. The implant is of a non-embedded structure and is integrated with a foundation. The upper part of the foundation is provided with a foundation pole, the lower part of the foundation is provided with a foundation pile, and an expanded base plate is arranged between the foundation pole and the foundation pile. When the implant is an anterior tooth implant, the gum-penetrating part of the foundation pile is also provided with an expanded bamboo joint shaped foundation pile joint. The body part and the root part of the implant are provided with threads, the thread of the body part is a shallow trapezoidal thread, and the thread of the root part is a deep triangular thread. The under-neck part of the implant, implanted into an alveolar bone, is fused with bioactive glass ceramic artificial bone dust. The implant has a reasonable design structure, is difficult to break off, has better biocompatibility compared with a pure titanium implant, and has higher bone combination intensity compared with a hydroxyapatite coated implant. |
