Titanium-based abutment structure of artificial root

This creation is about the application field of artificial roots, especially the titanium-based abutment structure of artificial roots.

Conventional dental treatment often uses crowns and bridges to repair teeth or strengthen interdental structures. If the teeth are removed due to the removal of natural teeth, the bridge can be used as a patch in the treatment. Adjacent teeth act as pillars to support the bridge. The disadvantage is that it will have a negative impact on adjacent healthy teeth. For example, two adjacent teeth in the edentulous area must be cut and ground, thus damaging the two original health. Teeth, but also have to set the braces for the two natural teeth, so the cost of the two crowns is much more.

However, with the advancement of science and technology, artificial dental implant technology has been developed, mainly by implanting the artificial root directly into the alveolar bone to replace the damaged root that has been removed. Among them, the abutment is important on the artificial root. Matching parts.

The Republic of China Invention Patent No. 196075, the invention provides a "supporting body structure for a sputum complex implant", characterized in that an axial through hole is formed in the center of the support body; During the process of screwing the male thread of the lower part of the table body and the implant body, the adhesive is prefilled into the threaded hole of the upper part of the implant body, and the excess amount can be followed by the support body. The axial through hole of the portion is squished and discharged to the outside of the top surface of the abutment body, so that after the joint body and the implant are finished, the residual remaining on the upper surface of the upper portion of the abutment body can be quickly and effectively removed. The adhesive on it.

Please refer to the Republic of China New Patent No. M404698, which discloses a structure of the artificial root root support. The support body can be used together with the artificial root and the fixed part, and the artificial root and the support body are combined by the fixing member. For artificial dental implant surgery. The abutment body is used for the artificial dental implant position of the last two large molars, and the support body is divided into an upper half and a lower half. The length and width ratio of the upper end surface of the abutment body are consistent with the ratio of the natural tooth and the large molars. The lower half of the abutment body extends upward from the socket segment by a circular arc surface, and the design and the design of the upper half are Compared with the abutment structure, it is more suitable as the abutment structure of the artificial root of the large molar region.

Please refer to the Republic of China New Patent No. M404699, which discloses a positioning structure of an artificial root and abutment body, which is provided with a first positioning portion at the bottom end of a table body and a first portion at the bottom of the first positioning portion. The second positioning portion is configured to enable the abutment body to be stably seated on the artificial root.

However, the degree of bonding between the crown and the abutment body is lowered due to prolonged use, resulting in easy fall of the crown.

In view of this, the creator has improved the shortcomings of the prior art, and after years of experience in this industry, he created the creation.

The creation system provides a titanium-based abutment body structure of an artificial root. The artificial root system can drill through the gums and enter the alveolar bone for screwing.
