LINK FOR CUSTOMIZED ZIRCONIA ABUTMENT OF DENTAL IMPLANT

摘要

The present invention installs a link having a length corresponding to the length of a zirconia cap, regardless of the size of a zirconia abutment installed according to the patient, such that there is no concern that the zirconia cap may escape from the link. According to the present invention, furthermore, the part of the link, which is installed inside the zirconia cap, has a size decreasing towards the upper portion such that the zirconia cap has a thickness maintained within a predetermined range, thereby removing any danger that the zirconia cap may be fractured by an external force. The present invention, in addition, forms the link as a single structure, which has a closed upper surface, using a titanium material to be coupled to the zirconia cap; therefore, the link not only has a substantially simple shape compared with a conventional link for a customized zirconia abutment, but the substantially shorter time taken for milling by a lathe operation facilitates manufacturing; the adoption of a structure, which has no screw hole therein, reduces the size and thus decreases the amount of titanium round rods used; particularly, the absence of a hole, to which a screw is fastened, eliminates the use of screws, thereby reducing the manufacturing costs to a large extent, lowering the price of the overall customized zirconia abutment, and lessening the burdens on the dentists and patients who use the same; furthermore, use of a customized titanium abutment is replaced, for such reasons, by use of a zirconia abutment, thereby reducing malfunctions of CAM equipment, which is imported at a high price, lengthening the service life thereof, and solving problems of small-scale dental technological factories.
