Problems solved by technology

[0009] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a one-time implantable composite dental implant, which solves the need to combine expensive multi-component structures in the entire process of dental restoration, resulting in complicated operation and positive parts. It is produced with the existing equipment, and the processing technology and precision cannot be closely matched, and the central bolt channel of the implant destroys its overall strength and causes the problem of bone tissue absorption.

Embodiment 1

[0033] Embodiment one: by Figure 1 to Figure 3 Given, a one-time implantable composite dental implant, the composite dental implant includes an integrated retention structure 11, a gingival segment 21 and a helical retainer 31 from top to bottom, and the retention structure 11 includes a central bolt channel 111. Retention plane 113 and retention outer wall 112. The central bolt channel 111 is a metric coarse thread with thread specifications of M1.4, M1.6, and M1.8. The retention outer wall 112 includes an upper retention outer wall 1121 and a lower retention outer wall 1121. The retaining outer wall 1122, the upper retaining outer wall 1121 and the lower retaining outer wall 1122 are discontinuous slopes under the same taper, which can be seamlessly fitted with the denture structure connected thereto, and the gingival passage 21 includes a gingival platform 211 and a platform transfer section 212, the platform transfer section 212 is a concave arc surface with a radius of 0...

Embodiment 2

[0034] Embodiment 2, on the basis of Embodiment 1, the helical retainer 31 implanted in human tissue sequentially includes a cylindrical section 312, a conical section 313 and a tail cone section 314 from top to bottom, and the cylindrical section 312 is cylindrical with upper and lower diameters, and the height of the cylindrical section is between 0.15 mm and 0.5 mm, which can increase the contact area between the implant and the jaw, and improve the stability of the implant. The tapered section 313 consists of The diameter of the end close to the cylindrical section 312 is reduced to the end close to the tail cone section 314 to form an inverted cone shape. To achieve excellent initial stability even when the bone quality is poor, the tail cone section 314 is an arc-shaped cone whose side is protruding outward, and the outer surfaces of the cylindrical section 312 and the tapered section 313 are arranged There is a continuous helical thread 315 .

Embodiment 3

[0036] Embodiment 3, on the basis of Embodiment 2, the helical thread 315 is provided with a cutting edge 311, and the helical cutting edge 311 is formed by setting a triangular notch on the helical thread, and each of the helical cutting edges is formed in each circle of the helical thread. There are three equidistant arrays around the central axis. The rotation angle of the helical cutting edge 311 is 10°-30° relative to the central axis of the implant, which can adjust the implant direction and has good self-tapping performance.

Abstract

The invention relates to the technical field of dental implants, specifically to a one-time implantation type composite dental implant.. According to the invention, in the whole conventional dental restoration process, expensive multi-component structures need to be combined together; operation is complex; and the effect is poor. The one-time implantation type composite dental implant provided bythe invention sequentially comprises an integrated retention structure, a gingiva penetrating section and a spiral retention body from top to bottom, wherein the retention structure comprises a central bolt channel, a retention plane and a retention outer wall; the retention outer wall comprises an upper retention outer wall and a lower retention outer wall; the upper retention outer wall and thelower retention outer wall are discontinuous slopes under the same taper; the gingiva penetrating section comprises a gingiva penetrating platform and a platform transferring section; the central boltchannel is located in the centers of the retention structure and the gingiva penetrating platform; and the platform transferring section and the spiral retention body are of solid structures. The one-time implantation type composite dental implant provided by the invention has the following advantages: the whole operation is completed through one-time implantation; the retention performance is excellent; dental diseases are not prone to being caused; human health is not affected; and the one-time implantation type composite dental implant has good development prospects in the technical fieldof dental implants.

Description

technical field [0001] The invention relates to the technical field of dental implants, in particular to a one-time implant composite dental implant. Background technique [0002] Since Professor Branemark first applied the cylindrical threaded dental implant made of pure titanium to the clinic in 1965, he created a precedent for modern dental implant. After more than 40 years of development, modern dental implant technology has become mature and clinically applied. It has been widely used and has become one of the important methods for repairing dentition defect and loss. Up to now, there have been more than one hundred dental implant systems for clinical use in the world. After clinical verification and with the deepening of clinical application and research, it has been found that the dental implant system has the following defects: 1. The two-stage implant is the implant abutment and A type of implant in which the retainer is divided into two segments rather than a sing...
