Detailed Description
For a further understanding of the invention, preferred embodiments of the invention are described below in conjunction with the detailed description, but it is to be understood that these descriptions are merely provided for further explanation of the features and advantages of the invention, and are not intended to limit the scope of the claims.
As shown in figure 1, the dental screw of the present invention comprises a main body 1 and a polymer material layer 2.
Wherein the main body 1 is composed of a base part 1-1 and a body part 1-2 which are integrally formed. The body part 1-2 is conical and is a part for implanting the dental implant into human tissues; to increase the stability of the embedding, it is preferable that the taper of the body 1-2 is 5-10 degrees. The base 1-1 is also tapered, preferably the taper of the base 1-1 is 20-30 degrees. The base 1-1 is fixed on the upper surface of the body 1-2, and the two are coaxial; the base 1 is the part of the dental implant exposed outside the mucosa and provides support, retention and stabilization for the artificial denture of its upper structure. The center of the upper surface of the base part 1-1 is provided with a circular table hole 1-3, a square hole 1-4 is connected below the circular table hole 1-3, a threaded hole 1-5 is connected below the square hole 1-4, and preferably, the threaded hole 1-5 extends into the body part 1-2.
