Problems solved by technology

Existing dental implants either use additive manufacturing technology to form a certain rough surface on the dental implant body, or use subtractive manufacturing technology to generate holes and other structures on the dental implant body. The bone ingrowth effect between the dental implant and the bone prepared by the material manufacturing technology is not good, the fusion is insufficient, the long-term fixation effect is unstable, and in severe cases, the operation fails or the postoperative recovery is poor

Abstract

The invention discloses a dental implant preparation method. The method comprises the following steps: firstly, forming a hole or a groove in a dental implant body by the aid of various processing methods; secondly, building a cylindrical projection, a spherical projection or other stereoscopic shapes in the hole or the groove by the aid of additional material manufacturing technologies. A locking function is formed among an implant and bone tissues, the ideal space structures for growing new bones can be provided, attachment and proliferation abilities of bone tissue cells are improved, excellent bone combination is achieved, convergence among the dental implant and autologous tissues is improved, and the dental implant effectively plays a role in a human body for a long time, is excellent in mechanical property and high in mechanical strength, can effectively reduce stress shielding and keep effective mechanical support.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dental implant and a preparation method thereof. Background technique [0002] Dental implants are currently the most commonly used dental materials in clinical practice. The wide application of dental implants in dental treatment has significantly improved the problems that could not be solved clinically in the past, and the success rate of implantation has also reached quite satisfactory results. Existing dental implants either use additive manufacturing technology to form a certain rough surface on the dental implant body, or use subtractive manufacturing technology to generate holes and other structures on the dental implant body. The bone ingrowth effect between the dental implant and the bone prepared by the material manufacturing technology is not good, the fusion is insufficient, the long-term fixation effect is unstable, and in severe cases, the operation fail...
