Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to oral cavity material transfer instrument technology field especially a general type covering screw. BACKGROUND
[0002] In the implant tooth operation of modern dentistry, the most applied dental implant system includes three parts of dental implant, abutment and connecting screw. In the implant tooth operation process, first, the dental implant is implanted into the alveolar bone of the patient, then the corresponding repair abutment is installed above the dental implant according to the condition of the patient, locked by the connecting screw, finally, the dental crown is assembled on the abutment to complete the operation.
[0003] But these steps are completed in stages, and many auxiliary instruments and tools are needed, for example, after the dental implant is implanted, the covering screw needs to be installed on the dental implant, and after the dental implant and the upper gum tissue are stable, the secondary operation is carried out to complete the installation of the abutment. Among them, the covering screw is required to be tightly connected with the implant, and the inner cavity of the implant is sealed to prevent bacteria from entering and adhering and causing gum infection. SUMMARY
[0004] The main purpose of the utility model is to provide a general type covering screw to solve the above technical problems, effectively seal the inner cavity and prevent the micro-leakage of bacteria and foreign matters.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A general type covering screw, comprising a covering screw and an implant, a connecting hole is arranged on the implant, the covering screw is threadedly connected on the connecting hole, the covering screw comprises a sealing part, a connecting part and a fixing part, the sealing part, the connecting part and the fixing part are sequentially connected and fixed from top to bottom, a covering ring is arranged on the sealing part, and the covering ring is arranged on the upper end of the sealing part.
[0007] As a preferred technical scheme, a fixing hole is arranged on the covering ring, and the fixing hole is arranged on the covering ring with the center of the covering ring as the origin.
[0008] As a preferred technical scheme, an operation hole is arranged on the sealing part, and the operation hole is arranged on the upper end of the sealing part.
[0009] As a preferred technical scheme, the operation hole is a regular hexagonal hole, a regular quadrilateral hole, a straight line hole or a cross hole.
[0010] As a preferred technical scheme, a cutting groove is arranged on the implant, and the cutting groove is arranged on the side surface of the implant.
[0011] As a preferred technical scheme, the implant is provided with a guide groove, which is arranged at the upper end of the connecting hole and is connected with the connecting hole.
[0012] The general covering screw has the advantages that the covering screw is in threaded connection and pressing fit with the implant, the effect of sealing the inner cavity of the implant is achieved, the covering ring covers the surface of the implant and covers the gum around the implant, the suture line is threaded through the fixing hole to suture the gum, the micro-leakage of bacteria and foreign matters is prevented, and quick healing can be achieved. BRIEF DESCRIPTION OF DRAWINGS
[0013] Figure 1 The utility model relates to general covering screw's structural schematic diagram;
[0014] Figure 2 The utility model relates to general covering screw's sectional view. DETAILED DESCRIPTION
