Problems solved by technology

However, there are still some problems in the long-term success rate of implant dentures. For example, with the prolongation of observation time, implants will loosen and break after denture implantation, which will lead to the failure of implant restoration surgery.
According to clinical observations, the main causes of implant loosening and fracture are the unreasonable design of the implant, the low strength of the neck, and the difficulty of osseointegration caused by bacteria and microorganisms easily entering the cortical bone during the implant operation. failure, resulting in loosening of the implant

Embodiment Construction

[0017] Hereinafter, the present invention will be described in detail through the accompanying drawings and embodiments.

[0018] As shown in Figure 1, the present invention is a two-segment non-embedded dental implant. The top of the implant is a circular platform 1 with a large upper and a small bottom. The top edge of the circular platform 1 has a chamfer 2 and the lower part of the circular platform 1 is the implant The neck of the body is a fine thread 3 with a diameter of 3.7mm, the pitch of the fine thread 3 is 0.3mm, and the tooth height is 0.15mm. Immediately below the fine thread 3, that is, the root of the implant is a straight thread 4, the end of the straight thread 4 has a taper, and there are three self-tapping cutting grooves 5 (as shown in Figure 2), the three self-tapping cutting grooves 5 are mutually spaced 120° setting. As shown in Figures 1 and 3, a cone hole 6 is opened inwardly at the top of the truncated platform 1 of the implant, and the taper of the cone...

Abstract

The micro thread implant includes one conic top with larger upper part and smaller lower part, one conic hole including one octagonal middle part and one lower screw hole part and surface coating of hydroxyapatite. It features the neck with fine thread, the root part with self-tapping straight thread and the conic end, with both the fine thread and the straight thread being saw tooth threads. The present invention has high neck strength, capacity of preventing microbes from invading, easy integrating with bone, easy screwing into the jaw bone and self locking, and may be used in repair dental defection, especially false tooth implanting operation.

Description

Technical field [0001] The invention relates to a medical device, in particular to a micro-threaded implant with biological sealing function for full jaw implant denture. Background technique [0002] Oral implantology is a cross-industry medical technology developed in the 1960s. It is a comprehensive technical discipline involving medicine, electronics, machinery, materials, and biomechanics. Implant dentures are an important part of oral implantology. Implant dentures are widely used in the restoration of dentition defects and missing, especially the application of full jaw implant dentures. It solves some problems that cannot be solved by conventional denture restorations for patients with severe alveolar ridge resorption. However, there are still some problems with the long-term success rate of implant dentures. For example, with the prolonged observation time, the implant will loosen and break after implantation, which will lead to the failure of implant restoration surgery...
