Edentulous jaw implant denture repairing window-type impression connector

Abstract

The invention relates to the technical field of medical appliances and discloses an edentulous jaw implant denture repairing window-type impression connector. On a transfer bar of the impression, themiddle part is a fixing portion, the upper part is a shaft shoulder and the lower part is an implant portion. A body of the connector is a round-shaped board having an inner hole of which the diameteris equal to the outer diameter of the upper part of the transfer bar. The side surface of the connector has a square shape being same as the radian of the side surface of the transfer bar. A first ring and a second ring are arranged on the left and right sides of the square shape respectively. The two rings are located at two heights to form an angle therebetween and are respectively connected tothe connector at the front or back side via a connection bar. The connector is convenient to use and can connect the transfer bars stably, thus accurately determining the relative positions of the implants during transfer. The connector can reduce operation time, improve clinical efficiency and increase the precision of horizontal impression of implants.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a window-type impression connector for edentulous implant denture restoration. Background technique [0002] Restoring the aesthetics and masticatory function of edentulous patients is a clinical problem in stomatology. For edentulous patients, the traditional complete denture restoration method is usually used in clinical practice, but due to its poor retention and stability, it is difficult to be accepted and adapted by edentulous patients. In recent years, with the rapid development of oral implant technology, more and more edentulous patients have accepted edentulous implant restoration technology, including edentulous overlay implant restoration technology and edentulous fixed implant denture. Restoration techniques. Oral implant restorations are well-retained, beautiful and comfortable, especially full-mouth fixed denture restorations, which do not have the disadv...

Problems solved by technology

However, the steel wire material used for connection has the disadvantage of being prone to relative sliding and the risk of clinical complications such as physical trauma to the oral mucosa; the resin material used for connection has the disadvantages of insufficient retention force and possible deformation and displacement due to its limited strength. , will lead to a reduction in the accuracy of the impression. At the same time, if the doctor does not operate properly, the resin will enter the hole of the transfer rod screw and block it, which will greatly increase the difficulty and time of clinical operation.
