Oral implant with appropriate initial-stage load stimulation

An oral implant and initial load technology, applied in the fields of dental implant, medical science, dentistry, etc., can solve the problem that the stability of the implant is not enough to resist the complex oral environment, which affects the success rate of restoration and the visual effect of restoration, bone and implant Weak integration at the body interface can avoid fracture damage, avoid bone resorption, and ensure the aesthetic effect of the repair

Problems solved by technology

On the one hand, the implant can obtain the initial stability necessary for osseointegration, but on the other hand, it will cause bone fracture damage, especially the impact on cortical bone is more serious
Bone damage will cause a series of adverse reactions: lead to bone resorption, which will seriously affect the success rate of repair and the visual effect of repair; delay the speed of osseointegration
At the same time, studies have confirmed that after implant surgery, the early stability of the implant will gradually disappear with the process of bone reconstruction.
At the same time, the integration between the bone and the implant interface is still very weak, resulting in the overall stability of the implant is not enough to resist the complex oral environment, resulting in loosening, falling off and other implant failures

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] see figure 1 , Figure 1A , Figure 1B , Figure 1C , Figure 1D , Figure 1E As shown, the oral implant designed by the present invention has a suitable initial load stimulation, and the oral implant is designed as an integrated structure. The oral implant is divided into a transgingival segment 10 , a cortical bone fixation segment 20 , a cancellous bone fixation segment 30 and an introduction fixation segment 40 from top to bottom. The center of the oral implant is a composite cavity 50, which is used to place the abutment for installing dentures (dentures).

[0028] see Figure 1B , Figure 1E As shown, in the present invention, the height of the gingival segment 10 is denoted as d 1 . The shape of the gingival segment 10 includes a circular frustum 102 with a small top and a large bottom and a circular frustum 101 with a large top and a ...

Abstract

The invention discloses an oral implant with appropriate initial-stage load stimulation. The oral implant is designed into an integrated structure and is divided into a gingival penetration section, a cortical bone fixing section, a spongy bone fixing section and a lead-in fixing section from top to bottom, wherein the center of the oral implant is a composite cavity; the outer surface of the cortical bone fixing section is provided with growing grooves which are staggered longitudinally and transversely; and the lead-in fixing section is 1 / 3 of a segment, and a cross groove is formed at the bottom of the lead-in fixing section. After the implant disclosed by the invention is implanted, an appropriate stress environment is generated in an alveolar ridge crest region, thereby effectively avoiding bone injury and bone absorption, and being favorable for exciting bone remodeling and promoting bone integration. In addition, the growing grooves which are staggered longitudinally and transversely can induce the growth of new bones to form a stable mechanical mosaic structure, thereby being suitable for complex oral occlusion mechanical environments.

Description

technical field [0001] The invention relates to an oral implant, in particular to an oral implant with suitable initial load stimulation. Background technique [0002] At present, there are three common methods of restoring missing teeth in oral clinic: removable dentures, fixed dentures and dental implants. Removable dentures are attached to the adjacent teeth of the missing tooth by using a retention mechanism, which has the characteristics of free removal and easy cleaning; however, the retention and aesthetics are poor, affecting chewing, foreign body sensation, and easy to cause dysphonia. Fixed dentures use the adjacent teeth as the base teeth, and the dentures are fixed on it with the help of adhesives. The patient does not need to take and wear them by himself. It has the characteristics of small size, comfort, beauty, and no foreign body sensation; Normal tissue is healthy and the bottom of the denture is not easy to clean. [0003] In the 1960s, an orthopedic exp...
