Description

Titanium metal support bone nail for dental bone repairing titanium film

The present invention is a titanium metal support bone for dental bone repair, and has a plug for positioning and placing a special non-porous titanium film to form a bone regeneration device having both a bone-supporting space and an isolated epithelium function.

In the past, the support bones for dental bones, as shown in the third and fourth figures, contained a larger head and a protruding neck, and a screw underneath. The head is the driving part, and the protruding neck can be used as a support or a titanium film.

Larger and thicker heads occupy a space for bone replenishment and are not conducive to a narrow bone-filling space, lacking flexibility. The position where the titanium film is placed on the neck is too low, the height of the bone can be increased, and the effect of fixing the titanium film is not satisfactory. The oversized neck platform also limits the size of the titanium film to which it fits.

The size of the body screw is slightly larger, which reduces the space for bone replenishment and increases the risk of bone fracture caused by locking in thinner bones. The thread with smaller cutting force makes the nail difficult to fix on the alveolar bone. It is also necessary to drill a thicker bone to obtain stability, which increases the risk of harming important anatomical structures, such as the bone above the alveolar nerve is too thin, the upper sinus is approaching or the nasal cavity is approaching.

The main purpose of this creation is to provide a titanium metal snail for dental bone repair. Silk, which has a plug that can be used in combination with a special titanium film for bone repair. This creation also improves the shortcomings of the support screws used in the past, and uses new structural elements to achieve the best bone-reinforcing effect, including the following: The head has a driving portion above it to facilitate the use of a tool to rotate the nail. The reduced head space and the shape of the adduction can provide more bone-reinforcing space than previous designs.

A neck, the upper head, and a latching groove on the structure for the titanium film to be inserted into the retaining position. The shortened head and neck distance can increase the placement of the titanium film and increase the height of the fill. The design of the pin groove makes it possible to stably place a special titanium film.

One body, the neck, the V-thread design, the end is self-tapping thread. The reduced screw diameter and increased bone space also reduce the risk of bone fracture. The end self-tapping screw design enhances the cutting force of the nail and is easier to obtain stability.

The roughened surface of the titanium metal support nail can increase the adhesion of blood and the growth of osteoblasts, thereby achieving the purpose of promoting bone regeneration.

This creation is a titanium metal support bone for dental bone repair (first picture, second picture), which has a pin groove (5) for titanium film retention (fifth, sixth), bone The surface of the nail is roughened to promote bone regeneration.

The support bone nail of the present invention has a head (1), a neck (2) and a body (3) in the structure. The head has a driving portion (4) for applying a tool to rotate the nail and screw it into the alveolar bone. The drive portion is a cross-shaped groove (7) for the force of the cross-shaped wrench. Shortened head height and volume can increase the space for bone repair. The neck is a pin groove as described above, which can be used to hold the special titanium film. In addition to extending the area supporting the nail, it can also be used as a barrier for the epithelium. The body is a V-threaded structure with a self-tapping screw (6) at the end for screwing into the alveolar bone and fixing the nail.

This creation is mainly used in the clinical application of dentistry. As shown in the seventh figure, the support bone nail is used to create the bone-filling space. The special titanium film is inserted into the pin groove on the bone nail to extend the space and provide more shielding effect to block the soft tissue from invading the space. In addition, a collagen regeneration film may be additionally applied to cover the support nail and the titanium film to achieve a better coverage space.
