DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to an anchoring device for dental prosthesis.
BACKGROUND OF THE INVENTION
The development of dental prostheses has focused on both longevity of operation of the prostehtic device as well as effectively anchoring the prosthetic device while causing the least possible harm to existing healthy teeth. Various unsuccessful attempts have been made to fulfill these requirements. In fact, the previously used prosthetics are either too flimsy or too sturdy for proper application, and may be difficult or even impossible to accurately adjust during usage.
SUMMARY OF THE INVENTION
The anchoring device of the present invention remedies these disadvantages by requiring that only a small hole be drilled in healthy teeth for the anchoring elements. Moreover, the anchoring elements withstand corrosion better, in addition to providing a larger fastening surface area than other prosthetics. This anchoring element can be used as an armature or foundation for the rebuilding of damaged teeth. It can also be used to anchor a beam across an interdental space to receive artificial teeth to replace missing teeth.
Essentially, the anchoring device of the present invention is comprised of a generally T-shaped anchoring element having a wide flattened bracket or head, containing a hole in the bracket. The T-shaped anchoring element is also provided with a cylindrical leg having several parallel axially concentric grooves.
The anchoring element is formed from a biosuitable metal having high structural qualities, such as titanium. The anchoring element is also sandblasted. The hole, grooves and sand-blasting of the anchoring element are intended to increase its bonding efficiency, both by increasing the bonding surface area and enhancing adhesion quality.
The anchoring device is further comprised of a beam formed by a U-shaped section with close set edges. The U-shaped section is made of a cloth or mesh of austenitic steel wire, for example.
In order to rebuild a damaged tooth, one or more T-shaped anchoring elements may be implanted in the healthy tooth near the section where a piece is missing. These elements act as an armature or framework for cavity-filling resinous material. These anchoring elements also offer a maximal adhesion surface area for the replacement tooth.
In replacing missing teeth with artificial teeth, one of the foregoing T-shaped anchoring elements is fixed to each of the side faces of the teeth defining an interdental space, and a beam made of the U-shaped metal cloth is adjusted for fit within the space. The U-shaped section is then jammed over the brackets of the T-shaped anchoring elements. The brackets are oriented with their major axes vertical, to this end. The T-shaped anchoring elements are staggered with respect to the height of the teeth into which they are placed. This prevents the risk of the angular displacement of the T-shaped anchoring element.
A non-limiting example of an embodiment of the present invention is described in the following detailed description in connection with the accompanying drawings, in which:
