The invention discloses a zirconia base station, which comprises a gum penetrating section, a neck section and a connecting section, wherein the neck section is positioned between the gum penetrating section and the connecting section, a platform capable of supporting external restoration crowns is arranged on the connecting section, the connecting section is a cylinder, an automatic locking device is arranged on the side surface of the connecting section, the automatic locking device comprises a circular arc-shaped sliding channel and locking pieces, openings at two ends of the sliding channel are positioned on the same vertical line on the side surface of the connecting section, the locking pieces are connected in the sliding channel in a sliding manner, the arc length of the locking pieces is larger than that of the sliding channel, and the bottom end of the locking pieces is a streamline curved surface. According to the zirconia base disclosed by the invention, the automatic locking device is additionally arranged, so that the zirconia base can automatically deform and open when the zirconia base is sheathed and repaired with the dental crown, the dental crown is repaired by internal tensioning, and the dental implant can be firmly connected without using a screw.

Description

Zirconia base station

Technical Field

The invention relates to the technical field of dental implants, in particular to a zirconia abutment.

Background

Existing dental implants mainly include implants, abutments and restorative crowns. The abutment can provide retention, support and stabilization for the prosthetic crown. The existing base station connection modes are two, namely (1) a screw fixing connection base station: the abutment and the restoration dental crown are fixedly connected and restored through screws; (2) cementing and fixing the connecting base station: i.e. the abutment and the prosthetic crown are fixedly connected and repaired by cement. However, the screw fixing and connecting mode is easy to have the defects of screw loosening, breakage, unsightly appearance, poor tread form, micro-gap between the abutment and the repairing dental crown, and the like. The cementing and fixing connection mode has requirements on the application mode and the application amount of the cementing agent, the contact surface of the abutment and the repairing dental crown is required to be coated with the cementing agent, if the cementing agent is insufficient, the service life of the repairing dental crown is shortened, and if the cementing agent is excessive, the cementing agent overflows to cause pollution.

Disclosure of Invention

According to the zirconia base provided by the invention, the zirconia base adopts a deformation locking installation and fixation mode, and can be tensioned and fixed from inside after being sleeved with the prosthetic dental crown without screw fixation.

The utility model provides a zirconia base station, includes and wears gum section, neck section and linkage segment, the neck section is located and wears between gum section and the linkage segment, has the platform that can support peripheral hardware restoration dental crown, the linkage segment is the cylinder, and its side is equipped with automatic locking device, automatic locking device includes convex sliding channel and retaining member, the opening at sliding channel both ends is located the same vertical line of linkage segment side, sliding connection has the retaining member in the sliding channel, the arc length of retaining member is greater than sliding channel's arc length, the bottom of retaining member is streamlined curved surface.

Further, a limiting protrusion is arranged in the opening at the upper part of the sliding channel, and a barb matched with the limiting protrusion is arranged at the top end of the locking piece.

Further, the connecting section is a regular hexagonal prism, and each side face is provided with an automatic locking device.

According to the zirconia base disclosed by the invention, the automatic locking device is additionally arranged, so that the zirconia base can automatically deform and open when the zirconia base is sheathed and repaired with the dental crown, the dental crown is repaired by internal tensioning, and the dental implant can be firmly connected without using a screw.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings that are required to be used in the description of the embodiments will be briefly described below. It is evident that the drawings described are only some embodiments of the invention, but not all embodiments, and that other designs and drawings can be obtained from these drawings by a person skilled in the art without inventive effort.

Detailed Description

The conception, specific structure, and technical effects produced by the present invention will be clearly and completely described below with reference to the embodiments and the drawings to fully understand the objects, features, and effects of the present invention. It is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments, and that other embodiments obtained by those skilled in the art without inventive effort are within the scope of the present invention. In addition, all coupling/connection relationships mentioned herein do not refer to direct connection of the components, but rather, refer to the fact that a more optimal coupling structure may be formed by adding or subtracting coupling aids depending on the particular implementation. The technical features in the invention can be interactively combined on the premise of no contradiction and conflict.

As shown in fig. 1 and 2, a zirconia abutment comprises a gum penetrating section 3, a neck section 2 and a connecting section 1, wherein the neck section 2 is positioned between the gum penetrating section 3 and the connecting section 1, a platform capable of supporting a peripheral restoration dental crown is arranged on the neck section, the connecting section 1 is a cylinder, an automatic locking device is arranged on the side surface of the connecting section, the automatic locking device comprises a circular arc-shaped sliding channel 11 and a locking piece 12, openings at two ends of the sliding channel 11 are positioned on the same vertical line on the side surface of the connecting section 1, the locking piece 12 is connected in the sliding channel 11 in a sliding manner, the arc length of the locking piece 12 is larger than that of the sliding channel 11, and the bottom end of the locking piece 12 is a streamline curved surface. Before the zirconia abutment is assembled with the prosthetic crown, the bottom end of the locking member 12 is exposed out of the opening at the lower portion of the sliding channel 11 and the top end is hidden in the opening at the upper portion of the sliding channel 11 due to the fact that the arc length of the locking member 12 is longer than that of the sliding channel 11 and the influence of gravity. When the zirconia abutment is assembled with the restoration dental crown, the inner wall of the restoration dental crown can press the streamline curved surface at the bottom end of the locking piece 12, so that the locking piece 12 slides upwards along the sliding channel 11, the top end of the locking piece 12 extends out of the opening at the upper part of the sliding channel 11, the purpose of tensioning the inner wall of the restoration dental crown is achieved, and the effect of fixed connection is achieved.

As a further preferred embodiment, a limiting protrusion is disposed in the opening at the upper part of the sliding channel 11, and a barb adapted to the limiting protrusion is disposed at the top end of the locking member 12. The barbs can both help prevent the locking element 12 from sliding out of the sliding channel 11 when not in use and also serve to improve the positioning of the locking element 12 when in tension.

As a further preferred embodiment, the connecting section 1 is a regular hexagonal prism, and each side is provided with an automatic locking device. The automatic locking device needs to be symmetrically arranged to better play a stabilizing role.

While the preferred embodiments of the present invention have been illustrated and described, the present invention is not limited to the embodiments, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the present invention, and these are intended to be included in the scope of the present invention as defined in the appended claims.
