Description

Dental implants and dental implant devices placed across the jawbone

The present invention relates to a dental implant plate and a dental implant device, and in particular, to a dental implant plate and a dental implant device straddling the jawbone.

When people encounter the problem of missing teeth, they can choose to use dental bridges, removable dentures and dental implants to fill the missing teeth. Because dental implants have better chewing strength and stability, and have no foreign body sensation, they are still a popular option for filling missing teeth, although the treatment course is longer and the cost is higher.

Dental implants are artificial tooth roots (implants) implanted into the alveolar bone. During the process of implanting the implant into the alveolar bone, the gums need to be opened and the implant is inserted. This is an invasive surgical procedure. After implantation, you need to wait 3 to 6 months for the implant to fully integrate with the bone, and then install the artificial crown on the implant. For example, my country’s announcements M364506, M494593, M497997, I571246, M603342, M623774, M627938, etc. are all implant structures for dental implants.

Although alveolar bone tissue can be proliferated to cover the implant through the restoration and regeneration of alveolar bone cells, when the teeth are chewing, they will cause various external forces in uncertain directions or torques in various rotational directions, which will affect the implant. The implant has forces applied outside the axial direction, and this eccentric force is not evenly distributed around the implant. This will cause stress concentration on the surrounding bones, pushing and vibrating, causing bone loss, and the implant will therefore be damaged. Loosening occurs, resulting in dental implant failure.

In order to improve the above deficiencies, the industry has developed implants that can enhance the stability of dental implants, such as my country's announcements I578965, I595861, I700076, and M452753, US announcements US5,906,489, US 8,202,089, US 9,877,807, US 5052930, and US publications US 20060154205, US 20090317765, US 20110171601, US 20140248583, US 20160250001, US 20170290645, etc. However, the reinforcement techniques disclosed in the above-mentioned documents basically use screws to pass through the perforations on the wing ends of the graft plates and then lock them into the jawbone. The graft plates only cover the jawbone and do not have the clamping force of a clamp. ; In addition, as mentioned above, when the teeth are chewing, they will cause various external forces in uncertain directions or torques in various rotation directions, which are then transmitted to the lower end through the abutment to bear the force, and the implant plate will bear the first impact. Because the screws pass through the perforations of the implant plate and then lock into the jawbone, the implant plate is locked and fixed. When the implant plate deforms due to force, the force will be directly applied to the screws, causing the screws to Looseness ultimately leads to dental implant failure.

In view of the above conventional situation, the object of the present invention is to provide a dental implant plate that is placed across the jawbone. The extension plates connecting the two sides of the base plate have surfaces facing each other for firmly clamping the jawbone. It is elastic and can penetrate the surface of the jawbone with the spikes on the extension plate. When the jawbone is hard, micro-grooving can be done with instruments first. Therefore, the dental implant can not only be firmly grasped on the flat jawbone, but can also be used in different places. The flat jawbone is used as a supporting scaffold for bone repair, and then combined with the implant components to form a dental implant device. It will be able to comprehensively support and disperse the bite force from the upper end, effectively improving the bone loss caused by the long-term instability of traditional implants. It can make the dental implant device more stable and prevent it from loosening for a long time.
