Abstract

The present invention relates to an implant abutment and a prosthetic system coupled by a spring which is made of metal or a high-strength synthetic resin to manufacture a prosthesis with a natural shape at a correct position without using screws or cement and a frictional force when connecting an implant prosthesis to an implant abutment.

Description

The present invention relates to a dental implant abutment system connected with a spring attachment system,

The present invention relates to an implant abutment to which at least one of a C-type spring, a release spring, or a ball spring is coupled to a selected spring attachment without using a screw or a cement to connect the implant prosthesis to an implant abutment, Implant abutment system consisting of cap, CAD / CAM block and recognition index for CAD / CAM

     To connect the implant prosthesis to the abutment abutment, a screw was used or a cement was used. However, the screw connection method has an advantage that it can be easily removed and repaired when the prosthesis is damaged. However, it has a disadvantage that not only the aesthetic problem is caused due to the hole of the thread, but also the prosthesis is dropped due to the screw being loosened or broken due to the repeated external force The cement-bonded method is aesthetic because it does not have holes in the thread. It overcomes the disadvantages of detachment of prosthesis due to bonding by cement. However, when excessive cement penetrates into the tissue and can not be removed, the necrosis Or it is difficult to remove it when the prosthesis is damaged. In recent years, aesthetic prosthesis has been pursued. To prepare an implant prosthesis in the form and color of a natural tooth, a ceramic prosthesis of a tooth shape at a depth of 2 mm or more is required. Because of this, it is difficult to remove excessive amount of cement in cement bonding. Therefore, studies on the bonding using abrasive force between the abutment and the prosthesis are being conducted as a method for connecting the prosthesis to the abutment. Korean Patent Laid-Open Publication No. 10-1077826 discloses that the frictional engagement type dental implant was attempted to obtain the frictional force by maintaining the angle of the interface between the abutment and the prosthesis by 1 to 4 degrees. However, the orthodontic stability of the prosthesis could not be provided. In the patent 80430892, And to obtain the frictional force by tilting the interface between abutment and prosthesis. However, since the friction between the inner surface of the prosthesis and the outer surface of the abutment due to repeated prosthesis removal process during the prosthesis manufacturing process is reduced, frictional force is severely lost in the oral cavity, or the prosthesis is inflated by repeated occlusal force It has a problem of being eliminated. In addition, U.S. Patent No. 8043089 discloses a method of attaching and detaching a removable denture to an implant abutment using a ball-shaped structure on the upper part of the abutment and a concave-convex connection with a silicon ring or a plastic cap recessed in the abutment. However, these silicone rings and plastic caps are easily worn due to frequent attachment and detachment due to long-term use.

In order to solve these problems, a spring made of metal or high strength synthetic resin is used to connect the prosthesis and the zone week.

To connect the implant prosthesis to the abutment abutment, a combined abutment abutment and prosthesis using springs made of metal or high-strength synthetic resin to fabricate the prosthesis in a precise position and a natural shape without using screws, cement or frictional force Caps, healing caps, CAD / CAM blocks and CAD / CAM recognition indexes should be integrated to create a system with precision, reproducibility and retention.

In the present invention, in connecting the implant prosthesis to the implant abutment, at least one of the C-type spring, the release spring, or the ball spring is combined with the selected spring attachment without using screws or cement, and the prosthesis cap , A healing cap, a CAD / CAM block, and a recognition index for CAD / CAM. The spring attachment is placed in the abutment or in the abutment part of the implant in which the abutment part and the fixation part are integrally formed. An implant abutment for a crown or a continuous fixed prosthesis is provided with a groove to which a spring is fixed on the outer surface. A driver polygonal groove or protrusion is formed for preventing the rotation of the prosthesis or for fastening the abutment, or a through- . A groove for fixing the spring to be fixed to the implant abutment for the removable dent is formed, and a driver polygonal groove or protrusion is formed to fasten the abutment to the ball-shaped head for freely moving the prosthesis. The material of the spring attachment is selected from metals such as titanium and its alloys, heat-treated carbon steel or stainless steel, gold alloys, chrome-cobalt or nickel alloys, aluminum alloys, and polymer materials such as polyethylene and polyetheretherketone . The healing coping has a coupling groove portion inside to be fastened to the abutment by the spring attachment, and has a gingival penetration portion having a shape similar to that of a natural tooth, and has an internal polygonal groove or protrusion for preventing rotation. The prosthetic coping has a concave and convex structure for bonding wax, prosthetic resin, ceramics, or resin and ceramics composite for casting on the outer surface, and has a concavo-convex structure on the outer surface for engaging with the abutment by a spring attachment. Ensure that the centerline is aligned with the centerline of the zone or is tilted up to 30 degrees. The materials for the healing copings and the prosthetic copings are plastics that can be cast into dental metals, titanium and its alloys that can combine resins with resins and ceramics, high melting points Gold alloy or chromium or nickel non-precious metal. The CAD / CAM block has a coupling groove in its inside to be fastened to the abutment by spring attachment. The material is made of ceramics such as alumina or zirconia, or a hybrid material in which ceramics or resin are bonded directly or bonded to the outside of the inner prosthesis. Or entirely of dental metal. The encoders for CAD / CAM machining have an engaging groove and an inner concave / convex portion to be engaged with the polygonal depression or projection of the abutment to be fastened to the abutment by spring attachment, and the orientation of the internal polygon on the outside, So that the eccentric protrusion is recognized.

The present invention provides a ceramic prosthesis for aesthetic prosthesis at a depth of 2 mm below the gingiva. It can be fixed without using screws, cement or frictional force, so it can charm the dislocation due to screw fracture, inflammation caused by cement and loss of frictional force, It is possible to repair the prosthesis because it can be removed from the prosthesis. It can be used as an attachment for fixing the removable denture, and it can reduce the exchange due to frequent abrasion by using metal or high strength plastic spring.
