Description

Abutment and implant comprising same

Technical Field

The application relates to the technical field of dental implants, in particular to a base station and a dental implant comprising the base station.

Background

Dental implants are a form of dental defect restoration that supports and retains an upper dental restoration based on a substructure implanted into bone tissue. It comprises three parts of an implant, a dental crown and a base station. One end of the implant is embedded and fixed into the alveolar bone of a patient, and the other end of the implant is fixedly connected with the base station in a threaded connection mode. A crown, i.e., a "denture" that replaces the patient's damaged teeth to achieve occlusion in cooperation with other teeth, is fixedly mounted on the outside of the abutment. Dental crowns generally comprise a "maxillofacial" region for the patient to perform a bite function and a "crown" region surrounding the maxillofacial region surrounding the abutment. The dental crown is generally provided with stepped through holes in the maxillofacial region for the screws on the abutment to pass through for connecting the implant, so that the dental crown, the abutment and the implant are integrally connected by the screws during clinical implantation (namely 'maxillofacial retention').

Although the implant can replace the patient's affected teeth to be matched with other teeth to realize the occlusion function, for the natural teeth, a periodontal membrane with the thickness of 0.15mm to 0.38mm is arranged around the natural teeth, and the implant connects the tooth root and the alveolar bone, so that the implant plays a role in relieving the impact on the alveolar bone during chewing. The implant is rigidly connected with the alveolar bone, the alveolar bone is severely worn after long-term use,

in the related art, chinese patent publication No. CN218458189U discloses an implant that buffers pressure against alveolar bone by providing a low-hardness film. But the implant and the abutment of the proposal are integrally designed. The implant is required to be pre-installed on the alveolar bone in actual use, after the gingiva and the alveolar bone grow normally, whether to continuously assemble the abutment and the dental crown is determined according to the health conditions of the gingiva and the alveolar bone, and the technical scheme of the related technology is easy to cause inflammation at the implant position after the implant is implanted by a patient in use, so that the implant is inconvenient in clinical use.

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1 to 12, the implant 100 provided herein includes: implant 110, abutment 120, crown 130, and cushioning layer 140.

Wherein, referring to fig. 2, one end of the implant 110 in the first direction a1 has a fixing portion 111 to fix the implant 110 to an alveolar bone of a patient through the fixing portion 111. The fixation portion 111 is generally configured as a threaded section 111a extending in a first direction a1 such that the implant 110 can be threadably coupled to the alveolar bone of the patient in the first direction a1 via the threaded section 111 a.

The abutment 120 is used to mount the dental crown 130 to the implant 110, and is fixedly mounted to an end of the implant 110 remote from the fixing part 111 in the first direction a 1. The dental crown 130 is fixedly disposed at one end of the abutment 120 away from the implant 110 along the first direction a 1.

Specifically, referring to fig. 1 and 2, the implant 110 is provided with an inner hole 112 along a first direction a1, and the inner hole 112 penetrates through an end of the implant 110 away from the fixing portion 111 along the first direction a 1. Correspondingly, the base 120 includes: a body 121. Wherein the body 121 is formed with a fixing structure 122 for fixing the abutment 120 to the implant 110 in the first direction a 1. The fixing structure 122 extends along the first direction a1 to enable the body 121 to be coupled with the implant 110 along the first direction a 1.

In an alternative embodiment, internal threads 112a extending in the first direction a1 are provided in the bore 112. Correspondingly, referring to fig. 3, the fixing structure 122 is configured as a fixing pin 122a formed on the body 121 to extend in the first direction a1, an external thread 122b capable of being engaged with the internal thread 112a formed on the implant 110 is formed at an end of the fixing pin 122a, so that the external thread 122b on the fixing pin 122a is screwed with the internal thread 112a in the inner hole 112 of the implant 110 by rotating the body 121, and the abutment 120 is fixed to an end of the implant 110 remote from the fixing part 111 in the first direction a 1.

In another alternative embodiment, referring to fig. 4, the fixing structure 122 is configured as a through hole 122c extending along the first direction a1, the through hole 122c penetrating the base 120 along the first direction a 1. Correspondingly, the base station 120 further includes: and a set screw 122d. Wherein, the end of the set screw 122d is formed with an external thread 122b that can be engaged with the internal thread 112a formed in the inner hole 112 of the implant 110. The set screw 122d is at least partially received inside the through hole 122c, and an end of the set screw 122d provided with the external thread 122b passes through the through hole 122c to form a screw-coupling with the implant 110, thereby fixedly coupling the abutment 120 to the implant 110.

Specifically, referring to fig. 1 to 8, the body 121 of the base 120 includes: an embedding portion 123. Wherein the embedded part 123 is used to be embedded inside the dental crown 130 so that the abutment 120 is combined with the dental crown 130.

More specifically, the crown 130 is located at an end of the implant 110 away from the alveolar bone in the first direction a 1. The crown 130 has a maxillofacial surface 131 and several crown surfaces 132. After the implant 100 is implanted in the user's mouth, the maxillofacial region 131 is used for the user to perform a bite function. Crown 132 is formed around crown 132. Jaw face 131 and crown faces 132 are surrounded by each other to form crown-inner groove 133 that is provided open at one end in first direction a 1. The crown inner groove 133 has a margin opening 133a that opens an end of the crown 130 away from the maxillofacial region 131 in the first direction a 1. The embedded portion 123 of the abutment 120 is at least partially embedded in the crown inner groove 133, thereby realizing the coupling of the crown 130 and the abutment 120. One end of the body 121 along the first direction a1 passes through the gap opening 133a and out of the coronal inner groove 133 to form a fixed connection with the implant 110.

The buffer layer 140 is fixedly disposed on the body 121. The at least one buffer layer 140 is located between the embedded portion 123 and the crown 130/at an end of the embedded portion 123 away from the fixing structure 122 along the first direction a 1. The buffer layer 140 may be made of a flexible material such as latex, and can absorb the impact of the crown 130 on the abutment 120 during the occlusion process of the user, thereby reducing the impact on the implant 110.

In this way, the buffer layer 140 is provided to buffer the impact on the alveolar bone during the occlusion process of the user, so that the implant 100 and the alveolar bone form a relatively flexible connection relationship, which corresponds to the function of simulating the periodontal ligament around the natural tooth by using the buffer layer 140. To reduce damage to the alveolar bone during use. The implant 110 and the abutment 120 are separately provided, and the abutment 120 and the crown 130 can be re-implanted into the oral cavity of the patient after a period of time after the implant 110 is implanted, so that the implant 100 can be more suitable for clinical application.

More specifically, periodontal ligament around natural teeth can be restored after being damaged, but the cushion provided manually is in a state of gradual loss during use. Therefore, the buffer layer 140 needs to be increased in thickness. However, the external dimensions of the crown 130 are adapted to the natural teeth, and the excessively thick buffer layer 140 will reduce the thickness of the crown 130, so that the crown 130 is easily broken during use. The thickness of the buffer layer 140 in this application is selected from a range of 0.4mm to 2.5mm, preferably 0.5mm to 2.0mm.

Specifically, the insertion portion 123 and the body 121 may be integrally formed or may be provided separately.

Referring to fig. 4, in an alternative embodiment, the embedded portion 123 is integrally formed at an end of the body 121 away from the fixing structure 122 along the first direction a 1. At this time, the buffer layer 140 is preferably fixedly disposed at one end of the embedded portion 123 away from the fixing structure 122 along the first direction a1, that is, the buffer layer 140 is located between the embedded portion 123 and the groove wall of the crown 130 forming the crown groove 133. More specifically, the buffer layer 140 may be fixed to the surface of the embedded portion 123 by means of gluing.

Referring to fig. 5 and 6, in another alternative embodiment, the embedded portion 123 is fixedly disposed at an end of the body 121 away from the fixing structure 122 along the first direction a1, and the buffer layer 140 is located between the embedded portion 123 and the body 121 along the first direction a1, that is, the buffer layer 140 is fixedly disposed inside the abutment 120 and is not in direct contact with the dental crown 130.

For clinical use, the crown 130 is typically made of porcelain or ceramic material, and the abutment 120 is typically made of titanium, which tends to have a surface roughness lower than the walls of the crown 130 that form the crown's inner groove 133. With the above arrangement, the cushioning layer 140 does not directly contact the crown 130 having a relatively rough surface, and the loss of the cushioning layer 140 is reduced, so that the implant 100 can be used for a longer period of time.

Specifically, the embedded portion 123 is provided with a mounting structure extending in the first direction a1, and the body 121 is provided with a fitting structure that fits with the mounting structure, so that the embedded portion 123 is fixedly connected to one end of the body 121 in the first direction a1 by the mounting structure and the fitting structure.

The manner in which the embedded portion 123 is fixedly connected to the body 121 may be selected according to practical needs, for example, the embedded portion 123 may be fixed to the body 121 by screwing.

Preferably, the embedded portion 123 is fixed to the body 121 in a sliding fit along the first direction a 1. For example, referring to fig. 5, the fitting structure is configured such that a slide groove 121a is provided at an inner wall of the body 121 where the through hole 122c is formed, and a first inner hole 121b communicating with the slide groove 121a, the slide groove 121a being provided open near one end of the embedded portion 123 in the first direction a 1. Correspondingly, the mounting structure is configured to be provided to the slider 123a of the insertion portion 123 extending in the first direction a1, and to be provided to the second inner hole 123b of the slider 123 a. During assembly, the slider 123a is inserted into the sliding groove 121a, so that the first inner hole 121b is opposite to the second inner hole 123b, and the insertion portion 123 can be fixed to the body 121 by inserting the positioning pin 150 between the first inner hole 121b and the second inner hole 123b, and the buffer layer 140 between the insertion portion 123 and the body 121 can be clamped and fixed.

For another example, referring to fig. 6, the mounting structure and the mating structure are snapped together. More specifically, the engaging mechanism is configured as a card slot 121c formed on the body 121, and the mounting structure is configured as a card bar 123c formed on the insertion portion 123, the card bar 123c being inserted into the card slot 121c such that the insertion portion 123 and the body 121 constitute a fixed connection. The mounting structure may be configured as a clamping groove 121c formed on the embedded portion 123, and the mating mechanism may be configured as a clamping strip 123c formed on the body 121, and the embedded portion 123 and the body 121 may be fixedly connected by fastening the two.

The sliding assembly fixing manner completes the assembly process by relatively sliding the embedded portion 123 and the body 121 when the embedded portion 123 and the body 121 are assembled, and the buffer layer 140 therebetween is relatively less damaged.

Referring to fig. 4, when the abutment 120 is fixed to the implant 110 by the aforementioned set screw 122d and the through hole 122c, at least a portion of the buffer layer 140 is inserted into the through hole 122c and contacts with a portion of the set screw 122d located in the through hole 122c, so that, when the user bites the crown 130 to receive a force different from the first direction a1, the impact force in this direction is absorbed by the portion of the buffer layer 140 contacting the set screw 122d, thereby reducing the impact transmitted to the implant 110 to further reduce the damage to the alveolar bone.

In this application, there is no particular limitation on the manner of fixing between the crown 130 and the abutment 120. For example, referring to fig. 7, the fixture screw 122d may be fixedly coupled to the implant 110 after passing through the penetration hole 134 and the through hole 122c in such a manner that the penetration hole 134 communicating with the crown inner groove 133 is provided on the maxillofacial surface 131 of the dental crown 130, thereby achieving the fitting fixation of the dental crown 130, the abutment 120 and the implant 110 by the fixture screw 122d, and achieving the "maxillofacial 131 retention".

For another example, referring to fig. 8, a threaded hole 123d may be formed in the abutment 120, and the threaded hole 123d extends in a direction different from the first direction a1, and accordingly, a screw is threaded through the crown 132 of the crown 130, and the crown 130 is fixed to the abutment 120 by screwing the screw into the threaded hole 123d, thereby completing the "crown 132 retention. In this embodiment, since the crown 132 of the dental crown 130 is provided with a hole corresponding to the threaded hole 123d, so that the screw can be inserted into the threaded hole 123d, it is preferable to use a method of fixing the abutment 120 to the implant 110 by matching the fixing screw 122d with the through hole 122c to ensure that the hole on the crown 132 is opposite to the threaded hole 123d.

In the related art, the implant 100 is often implanted in the oral cavity of a user singly, and in the case that a plurality of implant 100 are required to be implanted in the oral cavity of the user, the implant 100 is often required to be installed one by one in clinical operation, and the operation is time-consuming and laborious.

In clinical application, the dental implant 100 can be selectively connected with one of the crown surfaces 132 of the crown 130 of one dental implant 100 and one of the crown surfaces 132 of the crown 130 of the other dental implant 100 according to the oral condition of a patient, so that two dental implants 100 form a dental implant 100 group scheme, and the two dental crowns 130 can be synchronously installed in use or synchronously replaced in replacement of the dental crowns 130, thereby the operation is simpler and more convenient. Since the buffer layer 140 is provided on the abutment 120, the impact to the alveolar bone in which the implant 110 is implanted can be reduced, and thus, the problem of regional damage to the alveolar bone due to rigid connection of the plurality of implant teeth 100 and the alveolar bone can be avoided, so that the implant teeth 100 bridge the natural teeth 300, and it is possible to implant the plurality of implant teeth 100 at one time.

For natural tooth 200, there is normally some degree of physiological movement of the tooth in a healthy state, i.e., the tooth can rock slightly. The physiological power is mainly expressed in a direction in which the natural tooth 200 protrudes from the alveolar bone (i.e., the first direction a 1) which can be relatively far from or near to the tooth adjacent thereto. The physiological mobility is generally not more than 0.02mm, is not easy to detect, has a certain protection effect on teeth, and can buffer certain external force.

Specifically, referring to fig. 9, when the implant 100 of the present application is employed, the crown 130 can be made to rock with respect to the abutment 120 due to the buffer layer 140, that is, the crown 130 and the abutment 120 have functions similar to the aforementioned physiological movements. In this way, the abutment 120 according to the present application can be applied to the case of bridging between the implant 100 and the natural tooth 200, that is, the independent crown 300 is connected between the natural tooth and the crown 130 connected to the abutment 120, so that the independent crown 300 is supported and mounted by the natural tooth 200 and the implant 100. The limitation of the thickness of the buffer layer 140 allows the independent crown 300 to be relatively balanced against the impact of the implant 100 and the natural tooth 200 when engaged.

Specifically, referring to fig. 10, when the implant 100 is needed at a position where two non-adjacent teeth are located in the oral cavity of the patient, the crowns 130 of one implant 100 and the crowns 130 of the other implant 100 in the implant 100 set are arranged at intervals, and a connecting rib 160 is arranged between the two crowns 130 in the implant 100 set, and two ends of the connecting rib 160 are respectively connected to the crowns 132 of the two crowns 130 in the implant set, so that the crowns 132 of the two crowns 130 are connected. At this time, the two crowns 130 are replaced simultaneously. The connection rib 160 may be integrally formed with the crown 130 when the crown 130 is formed, or may be formed by bonding the crown surfaces 132 of both crowns 130 by an adhesive during the assembly process.

Alternatively, referring to fig. 11, the crown inner groove 133 may be defined to have a mounting opening 133b that allows one of the crown surfaces 132 of the crown 130 to be disposed open; the installation opening 133b is provided open at one end in the first direction a1, and communicates with the avoidance opening 133a. In this way, the crown 130 can be mounted to the abutment 120 in a second direction a2 different from the first direction a1, and then the mounting opening 133b can be closed by filling an adhesive. Particularly, when a plurality of implant teeth 100 are to be planted, the assembly method can mount or dismount the crown 130 from the side close to the tongue in the mouth of the patient, and compared with the method of mounting or dismounting the crown 130 from the first direction a1, the operation space is more sufficient, so that the assembly method is more suitable for clinical application, and the clinical operation difficulty is reduced.

Specifically, referring to fig. 12, when the implant 100 is required to be implanted at a position where two adjacent teeth are located in the oral cavity of the patient, a scheme may be selected in which one crown surface 132 of one implant 100 in the set of implants 100 abuts one crown surface 132 of the other implant 100 in the set of implants 100, and the two adjacent crown surfaces 132 are integrally formed. At this time, the installation and replacement of two adjacent crowns 130 may be performed simultaneously. And such a one-piece crown 130 composed of a plurality of crowns 130 can reduce or even eliminate the gaps between adjacent crowns 130, which is user-friendly.

It should be noted that, in the present application, the first direction a1 and the second direction a2 are preferably straight directions, and the straight line where the first direction a1 is located and the straight line where the second direction a2 is located are disposed obliquely or vertically. It should be understood that this section is a technical feature that restricts the positional relationship between the respective structures related to the first direction a1 and the second direction a2, and is not a limitation of the first direction a1 and the second direction a2 themselves.

The shapes of the components such as the crown 130, the abutment 120, the implant 110 and the like shown in the drawings are simplified to show the corresponding structures provided thereon, and the shapes thereof should be regarded as illustrations of the shapes of the products and should not be regarded as limitations on the shapes of the products.
