Internal connection and external insertion type conversion base station

Abstract

The utility model belongs to the technical field of false tooth implantation, and particularly relates to an internal connection and external insertion type conversion abutment which comprises a buffer part, an upper conical outer connector integrally formed at the upper part of the buffer part, a lower conical inner connector integrally formed at the lower part of the buffer part, and a hexagonal body integrally formed at the lower part of the inner connector, mounting holes are formed in the middle of the upper side of the outer connector, the middle of the upper side of the buffer part and the middle of the upper side of the inner connector. The outer connecting body and the false tooth crown are arranged to be of a structure which is matched with each other and connected through friction force between the outer connecting body and the false tooth crown, so that when the central screw in the abutment is loosened, a pair of common dental forceps is used for applying left-right rotating force on the false tooth crown, and after the operation is repeated for several times, the false tooth crown can be separated from the abutment; after the central screw is fastened by a tool subsequently, the false tooth crown is worn again, and the false tooth crown is connected with the abutment in a self-locking manner again, so that the operation mode not only ensures non-invasive operation, but also enables the repair operation to be very simple and quick.

Description

Technical Field

[0001] The utility model belongs to the technical field of denture implantation, in particular to an internally connected and externally plugged-in conversion base. Background Art

[0002] The Morse taper is a tapered cylinder with a smooth convex surface, called the male taper, and another matching hollow tapered cylinder with a smooth concave surface, called the female taper. After matching contact, the two have a connection function under the action of force. The closer the taper is to parallel, the tighter the connection is. The greater the wedging force, the tighter the connection is. This Morse taper phenomenon is widely used in the field of implant dentures.

[0003] In the field of dental implant dentures today, the most widely used method for connecting and retaining abutments and dental implants is the Morse taper center screw retention connection method. This method mostly uses a Morse taper of 5.7° to 11°. The abutment is the male cone part of the Morse taper, and the lower end of the abutment is located in the implant, which is an inverted cone-shaped cylindrical part. Directly below it is a regular hexagon or regular octagon structure for positioning and increasing anti-rotation ability. It has a central threaded hole fixing channel; the dental implant is a hollow structure. There is a female cone part that completely matches the male cone part of the abutment. There is a central retention threaded hole just below the female cone structure. The lower cone part of the abutment is placed in the female cone part of the dental implant and after they are in contact, the center screw is used to connect and fix the two. This type of dental implant connection method with Morse taper center screw connection and retention is called internal connection. If the center screw of the internal connection is loosened, the abutment and the dental implant will become loose. When the center screw is removed, the abutment and the dental implant will be completely separated.

[0004] The most commonly used dental implant system in clinical implant dentures today is the internal connection dental implant system, which is recognized by doctors for its diversified restoration forms of implant dentures. However, there is no better control method when the central screw of a single tooth implant denture becomes loose.

[0005] Therefore, in order to solve the above problems, an internal connection and external plug-in conversion base is proposed. Utility Model Content

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an internally connected external plug-in conversion base, comprising a buffer portion, an upper conical external connector integrally formed on the upper portion of the buffer portion, a lower conical internal connector integrally formed on the lower portion of the buffer portion, a hexagonal body integrally formed on the lower portion of the internal connector, a mounting hole is commonly provided in the upper middle portion of the external connector, the upper middle portion of the buffer portion and the upper middle portion of the internal connector, a through hole is commonly provided in the lower middle portion of the hexagonal body and the lower middle portion of the internal connector, the through hole is communicated with the mounting hole, a center screw is commonly slidably connected to the inside of the mounting hole and the inside of the through hole, and a denture crown is embedded in the outside of the external connector.

[0010] Preferably, the denture crown comprises a denture inner base crown, a denture modified porcelain surface is provided on the outside of the denture inner base crown, and the denture inner base crown is engaged with an external connector.

[0011] Preferably, the central screw includes a screw head, and a screw handle is fixedly connected to the lower part of the screw head.

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the present invention provides an internal connection and external plug-in conversion base, which has the following beneficial effects:

[0015] The internally connected externally plug-in conversion base has a structure in which the external connector and the denture crown are arranged to fit each other and are connected by friction between them. When the center screw in the base becomes loose, ordinary dental extraction forceps are used to apply left and right rotational force on the denture crown. After repeating this several times, the denture crown and the base can be separated. After tightening the center screw with tools, the denture crown is put on again to make the denture crown and the base self-lockingly connected again. This operation method not only ensures non-traumatic operation, but also makes the repair operation very simple and quick. BRIEF DESCRIPTION OF THE DRAWINGS
