Embodiment Construction

[0016] The present invention will be further described in conjunction with accompanying drawing:

[0017] As shown in the drawings, an oral implant device includes an implant composed of a neck 1, a body 2 and a root 3, an abutment 7, and a cap screw 10. The diameter of the neck 1 of the implant is slightly larger than the diameter of the body 2 And with a taper, the body part 2 of the implant adopts the tooth root type, the root part 3 of the implant has a self-tapping cutting groove 4, the internal structure of the implant adopts Morse taper 5 and the positioning of the inner fillet, and the inner neck is equipped with a stepped cylinder There is a small gap between the stepped cylindrical surface 9 and the abutment 7 to facilitate the entry of gingival tissue or bone cells. The Morse taper hole 5 inside the implant and the Morse taper rod of the abutment 7 that cooperate with it are respectively provided with The positioning groove and the positioning boss 6 can realize the...

Abstract

The invention discloses a dental implant assembly, which is characterized in that the diameter of the neck portion is slightly larger than that of the body portion of the dental implant and has a taper, the implant body portion has a dental root shape, the root portion of the dental implant has a self-tapping cut groove, the dental implant is provided inside with a Morse taper mechanism for fillet positioning, the neck portion is provided inside with a stepped cylindrical surface that is in clearance fit with an abutment, the junctions between the abutment and the dental implant are positioned on the stepped cylindrical surface, and the diameter of the upper part of the abutment is larger than that of the dental implant. The clearance between the abutment and the implant is helpful for in-growth of gingival and bone tissues. After implantation in vivo, the stress position for bondage between the dental plant and the abutment descends to prevent alveolar resorption due to overload on the neck portion of the dental implant; the marginal size of the abutment is enlarged to avoid food debris from entering implantation zone during chewing process. Additionally, the dental implant assembly fits well with a nut cap, thereby realizing implant esthetics.

Description

Technical field: [0001] The invention relates to a medical instrument, in particular to an oral implant device composed of a threaded implant implanted in the alveolar bone, a matching abutment, and a cap screw. Background technique: [0002] In the 1960s, Professor Branemark of the University of Gothenburg in Switzerland conducted research on oral implant materials and bone-implant interfaces, and created the theory of "osseointegration", which laid a theoretical foundation for the application of oral implantology. Dental implant application technology is the most important part of modern oral implantology. The extensive development and application of oral implant dentures have solved a series of aesthetic and functional problems caused by clinical missing teeth. However, the long-term success rate of implants is still worthy of our discussion and concern: as time goes by, the alveolar bone begins to resorb; the fit between the abutment and the implant begins to loosen; B...
