Description

Connector for dental implant and dental implant system equipped with same {CONNECTOR FOR DENTAL IMPLANT AND DENTAL IMPLANT SYSTEM HAVING THE SAME}

The present invention relates to a dental implant system, and more specifically, in a structure in which structures such as protrusions or grooves are formed on the post of an abutment to be restored by a crown (artificial tooth/prosthesis), the crown can be easily attached to the abutment. It relates to a connector that can be installed to prevent crown separation (falling off) and a dental implant system equipped with the same.

A dental implant system includes, for example, a fixture installed in the alveolar bone, an abutment that is fixed to the fixture and supports lateral or horizontal pressure in response to the occlusal force applied during mastication, and an abutment. It includes a crown (artificial tooth/prosthesis) that restores the upper part (post) of the tooth and restores aesthetic beauty similar to natural teeth.

Domestic Patent No. 10-1445298 and Domestic Patent No. 10-1808599 provide a structure for attaching a prosthesis to an abutment using a screw, however, in this structure, the bonding force between the prosthesis and the abutment is only the screw. As a structure that relies on a screw, if external force is continuously applied to the prosthesis due to repetitive mastication, the bonding force of the screw may become loose, which may cause a problem in which the bonding force between the prosthesis and the abutment decreases.

In Domestic Patent No. 10-2132353, a coupler is interposed between the prosthesis and the abutment, and in Domestic Patent No. 10-1445298 and Domestic Patent No. 10-1808599, the prosthesis rotates around the abutment and is screwed. Solved the problem of loose bonding force. However, as in Domestic Patent No. 10-1445298 and Domestic Patent No. 10-1808599, the bonding force between the prosthesis and the abutment is a structure that relies only on screws, and it is still difficult to maximize the bonding force between the prosthesis and the abutment. There may be limits.

Domestic Registered Patent No. 10-1924802 proposes an implant structure that connects the prosthesis to the upper part of the abutment via a screw bolt, similar to the above-mentioned prior literature. As in Patent No. 10-1808599, since the bonding force between the prosthesis and the abutment depends only on the bolt, there may still be limitations in maximizing the bonding force between the prosthesis and the abutment.

In addition, in Domestic Patent No. 10-2132353, unlike the existing implant structure, an additional coupler is installed between the prosthesis and the abutment, and in Domestic Patent No. 10-1924802, a coupler is installed between the prosthesis and the abutment to prevent the prosthesis from flowing. Since an additional buffering member must be installed between the implants, the structure of the implant becomes somewhat more complicated than before, which may ultimately make the implant procedure somewhat more difficult and increase the procedure time.

Additionally, the outer protrusion 61c formed on the outer surface of the connector 61 and the groove 62b recessed inward on the inner surface of the receiving space 62a of the crown 62 may have an annular structure.

Example 7

Figure 14 is an internal perspective view schematically showing a connector according to Example 7 of the present invention, and Figure 15 is a cross-sectional view schematically showing a crown coupled to the connector shown in Figure 14.

Referring to Figures 14 and 15, the connector 71 according to Example 7 of the present invention, like Example 1, is accommodated on the inner surface of the receiving space 71a so that the groove formed on the outer surface of the post of the abutment is engaged. An inner protrusion 71b is formed that protrudes into the center of the space 71a. In addition, a straight outer groove portion 71c extending from the top to the bottom is formed on the outer surface of the connector 71 instead of the annular structure. At this time, one straight outer groove 71c is formed on one side of the connector 71 as shown in FIG. 14, but this is only an example. In order to stably couple the crown 72 to the connector 71, the connector 71 ) It is desirable to form two pairs so that they are symmetrical to each other around the center. Of course, three, four, or more may be formed at even intervals along the outer peripheral surface of the connector 71.

As shown in (a) of FIG. 15, on the inner surface of the receiving space 72a of the crown 72 coupled to the connector 71 so as to cover the outer surface of the connector 71, a straight groove is inserted into and coupled to the linear outer groove portion 71c. A protrusion 72b is formed. Accordingly, as shown in (b) of FIG. 15, when the crown 72 is coupled to the connector 71, the position where the crown 72 is coupled can be easily recognized, and the straight protrusion formed on the crown 72 ( 72b) is coupled by sliding (guiding) from top to bottom along the linear outer groove 71c formed in the connector 71, making coupling simple and easy. In addition, the combination of the straight protrusion 72b and the straight outer groove 71c can fundamentally prevent the crown 72 from rotating in the rotation direction, that is, about the connector 71.

Example 8

FIG. 16 is a cross-sectional view schematically showing a connector according to Example 8 of the present invention, and FIG. 17 is a cross-sectional view schematically showing an abutment to which the connector shown in FIG. 16 is coupled.

And, on the outer surface of the post 82a of the abutment 82 to which the connector 81 is coupled, a straight groove 82b is formed so that the straight inner protrusion 81b can be slidably coupled.

Additionally, a structure opposite to Example 8 is also possible. For example, a straight inner groove may be formed on the inner surface of the receiving space of the connector, and a straight protrusion may be formed on the outer surface of the post of the abutment corresponding thereto. In addition, as in Example 7, a straight outer protrusion (or groove) is formed on the outer surface of the connector, and a straight groove (or protrusion) is formed on the inner surface of the corresponding crown so that the connector can be coupled between the abutment and the crown. It may be possible.

Meanwhile, the connectors according to Examples 1 to 8 may be made of elastic synthetic rubber or silicone rubber, or may be made of rigid metal or engineering plastic. Rigid metal or engineering plastic materials lack flexibility compared to elastic materials such as synthetic rubber or silicone rubber. For this reason, it may be difficult to connect the connector to an abutment made of a metal material such as titanium, or to connect the crown to the connector.

Therefore, in Examples 9 to 11 described below, when manufacturing a connector with a metal material or engineering plastic material, the side part of the connector is cut (communicated with the receiving space) to add flexibility, and various shapes of openings ( form a gap).

Example 9

Figure 18 is an internal perspective view schematically showing a connector according to Embodiment 9 of the present invention.

Referring to FIG. 18, the connector 91 according to Example 9 of the present invention is formed with a cut portion 91b cut upward and downward from the outer surface to the receiving space 91a on the side portion to add flexibility. The opening portion 91b has a straight structure, the width (spacing) of the opening portion 91b can be determined depending on the material of the connector 91, and the number of openings 91b can also be formed as one or more.

Referring to FIG. 19, the connector 101 according to the tenth embodiment of the present invention is formed with a cut portion (101b) cut up and down from the outer surface to the receiving space (101a) on the side portion to add flexibility. The slits 101b are formed diagonally along the outer surface of the side portion of the connector 101, and may be formed in one or more pieces depending on the material of the connector 101.

Example 11

Figure 20 is an internal perspective view schematically showing a connector according to Embodiment 11 of the present invention.

Referring to FIG. 20, the connector 111 according to the eleventh embodiment of the present invention has a slit 111b cut upward and downward from the outer surface to the receiving space 111a on the side portion to add flexibility. The slits 111b may be horizontally (horizontally) straight rather than vertically (vertically) as disclosed in Example 9, and their number may be adjusted depending on the material of the connector.

The openings applied to the connectors according to Examples 9 to 11 of the present invention may also be appropriately mixed with the connector structures proposed in Examples 1 to 8.

Meanwhile, when the connector according to embodiments of the present invention is made of flexible synthetic rubber or silicone rubber, when coupled to the post of the abutment, the coupling force with the structure formed on the post is relatively weak compared to the metal material. Because of this, even if the connector is coupled to the post structure, it can easily be separated from the post due to external shock. Considering this problem, different materials can be mixed and used as in Example 12.

Example 12

Figure 21 is a cross-sectional view schematically showing a connector according to Example 12 of the present invention.

Referring to Figure 21, the connector 121 according to the twelfth embodiment of the present invention is formed of a flexible synthetic rubber material or silicone rubber material, and the inner side is caught vertically in the groove portion, that is, the structure formed on the post of the abutment. A reinforcing ring 121c made of a harder material than that of the connector 121 may be additionally installed surrounding the protrusion 121b or below it.

The reinforcement ring 121c may be made of metal or plastic, and may be installed on the inner surface of the receiving space 121a or embedded in the inner wall of the receiving space 121a. At this time, the reinforcement ring 121c may have a C-ring structure for easy installation.

In the connector according to Examples 1 to 12 of the present invention, the inner protrusion (or inner groove) formed on the inner surface of the receiving space is formed in a shape corresponding to the groove (or protrusion) formed on the outer surface of the post of the abutment. do. At this time, the shape of the inner protrusion formed on the connector should be designed so that the connector can be smoothly and easily coupled when coupled (mounted) to the post, and so that the connector cannot be easily separated when coupled to the post.

Figure 22 is a schematic enlarged cross-sectional view showing the shape of the inner protrusion of the connector according to the present invention.

Referring to FIG. 22, the inner protrusion 131b of the connector 131 is located at the lower portion (where the connector enters the post mounting direction) with respect to the apex P of the inner protrusion 131b from the inner surface of the receiving space of the connector 131. The entrance side/dotted line area) (hereinafter referred to as the 'entry section') and the top (resistance side/solid line area stored in the direction in which the post leaves the connector) (hereinafter referred to as the 'resistance section') are asymmetrical structures. It can be done with For example, based on the apex P0 of the inner protrusion 131b, the entry part (dotted line area) is formed to have a gentle slope, and the resistance part (solid line area) is formed to have a relatively steep slope. In addition, the distance from the apex point (P0) of the inner protrusion (131b) to the starting point (P1) of the inner protrusion (131b) is longer than or equal to the distance from the apex point (P0) to the ending point (P2) of the inner protrusion (131b), and the inner protrusion (131b) Based on the apex (P0) of (131b), the elliptical radius of the entry portion may be greater than or equal to the elliptical radius of the resistance portion.

The structural characteristics of FIG. 22 can be equally applied to protrusions formed on the outer surface of the post. This allows the operator to mount the connector on the post without straining, and also prevents the crown from falling off unintentionally in daily life after the procedure is completed.

In the implant system equipped with a connector according to Examples 1 to 12 of the present invention, an elastic member such as synthetic rubber or silicone rubber may be additionally coated on the outer surface of the connector to improve the sealing force between the connector and the crown. You can. In particular, if the connector is made of a hard material such as metal or engineering plastic, the sealing force between the connector and the crown may be improved by additionally installing the elastic member.

Figure 23 is a perspective view schematically showing an example of an abutment to which the connector according to Examples 3 and 4 of the present invention is applied, where (a) has one annular protrusion, (b) has two annular protrusions, (c) shows the structure of the abutment post with three annular protrusions.

Meanwhile, the connectors according to Examples 1 to 12 of the present invention are each configured independently, but this is for convenience of explanation and may be configured by mixing them.
