Abstract

The invention relates to an implant with a plasma coated nano-zirconium oxide coating and a preparation method thereof. The implant comprises an implant body and an abutment, wherein the implant body is conical and is provided with threads; the abutment comprises a gum penetrating part, a shoulder and an abutment part; the gum penetrating part is conical and is fixedly connected with the implant body; the abutment part is conical and is fixedly connected with the gum penetrating part by virtue of the shoulder. The implant is made from a pure titanium or titanium alloy material, and is of a one-piece integral structure; the surfaces of the gum penetrating part and the shoulder are uniformly coated with a nano-zirconium oxide coating. The preparation method is performed in a mode of finely cutting and coating with plasma. The implant is made from a pure titanium or titanium alloy material and is of a one-piece integral structure, and the nano-zirconium oxide coating is uniformly coated to the surfaces of the gum penetrating part and the shoulder; the implant has the nice appearance of the zironium oxide abutment and excellent bioavailability, and has the mechanical strength of a titanium abutment.

Description

technical field [0001] The invention relates to an implant and a preparation method thereof, in particular to an implant with a pure titanium or titanium alloy surface plasma-sprayed with a nano-zirconia coating and a preparation method thereof, belonging to the technical field of dental implant materials. Background technique [0002] With the development of stomatology, dental implant technology has matured, and implants are the most important tool used in the dental implant process. The implant generally includes the implant body and the abutment. The abutment is an important structure connecting the implant body and the upper restoration. It, together with the surrounding soft tissue, restoration and the patient's oral environment, play an important role in maintaining the success of the implant denture. role. The pure titanium and titanium alloy abutments currently used clinically have good biocompatibility, and can be well matched with the implant body; however, the i...
