Description

Technical Field

[0001] This utility model relates to the field of dental implant restoration, and in particular to a dental implant restoration. Background Technology

[0002] After tooth loss, without intervention, the alveolar bone will gradually be absorbed due to the loss of physiological occlusal stimulation. This absorption usually begins immediately after tooth loss. To reduce alveolar bone resorption, immediate implant placement has become popular. Immediate implant placement involves inserting the implant immediately after tooth extraction, which can effectively shorten treatment time, reduce alveolar bone resorption, and quickly restore chewing function.

[0003] Because a socket is left in the alveolar bone after tooth extraction, and the socket is irregular in shape, while the mainstream root-shaped implants are regularly round, when inserting a traditional root-shaped implant into the socket of a freshly extracted tooth, the implant depth should reach 3-5mm below the apex of the original tooth root into the bone tissue (i.e., the implant should be screwed into the socket to a depth of 3-5mm). Figure 1 As shown, it relies on its mechanical locking force to ensure sufficient initial stability. Therefore, for immediate implant surgery, the use of traditional root-shaped implants has strict requirements on alveolar bone height, which often limits the suitable candidates for immediate implantation.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0029] like Figure 2-7 As shown, this utility model provides an oral implant prosthesis, including an implant 1, an abutment 2, and a prosthesis 3; the abutment 2 is disposed between the implant 1 and the prosthesis 3; the side of the abutment 2 near the prosthesis 3 is detachably connected to the prosthesis 3; the side of the abutment 2 near the implant 1 is fixedly connected to the implant 1.

[0030] The implant 1 includes a fixing component and an implant body 4; the implant body 4 is fitted onto the outer surface of the fixing component; the implant body 4 includes a plurality of implants 5; the plurality of implants 5 are evenly distributed along the central axis of the fixing component; each implant 5 is fixedly connected to the fixing component; the side of the implant 5 closest to the fixing component is fixedly connected to the fixing component; the side of the implant 5 furthest from the fixing component has a serrated edge.

[0031] In some embodiments, dental implant prostheses may include a one-piece dental implant prosthesis or a two-piece external interface dental implant prosthesis; regardless of the type, dental implant prostheses include an implant 1, an abutment 2, and a prosthesis 3, wherein the implant 1 is the portion inserted into the patient's extraction socket, that is, inserted into the alveolar bone, acting as an artificial root to provide support; the abutment 2 is the intermediate component connecting the implant 1 and the prosthesis 3, and the abutment 2 is used to fix the prosthesis 3 and distribute occlusal forces; the prosthesis 3 is the portion finally installed on the implant 1, that is, connected to the implant 1 via the abutment 2, and the prosthesis 3 is used to restore the patient's chewing function; the abutment 2 is disposed between the implant 1 and the prosthesis 3, The abutment 2 is fixedly connected to the implant 1 on the side near the implant 1, and the abutment 2 is detachably connected to the prosthesis 3 on the side near the prosthesis 3. The implant 1 includes a fixing component and an implant body 4. The fixing component is located at the center of the implant 1 and can be a regular column. The diameter of the fixing component is small so that the implant 1 and abutment 2 in the dental implant prosthesis can be smoothly inserted into the extraction socket by hammering. At the same time, due to the small diameter of the fixing component, it is difficult to process the interface connecting it to the implant 1 in the internal space. Moreover, if the internal interface is processed, the strength of the dental implant prosthesis is difficult to guarantee and it is easy to break. Therefore, a one-piece dental implant prosthesis or a two-piece external interface cavity implant prosthesis is designed.The implant body 4 includes multiple implant components 5, which are evenly distributed along the central axis of the fixation component. Each implant component 5 can be a blade-like structure, and each component 5 is fixedly connected to the fixation component. The side of the implant component 5 closest to the fixation component is fixedly connected, while the side furthest from the fixation component has a serrated edge, resembling a blade shape. By setting implant components 5 with serrated edges on the fixation component—in other words, by setting dental implant restorations with blade-like structures—both the traditional screw-in method of implantation is not applicable and avoids it. This eliminates the need for traditional drilling and tapping operations during the implantation process, i.e., cavity preparation. It also avoids the risk of bone burns during cavity preparation, reduces costs, simplifies the implantation process, and allows patients to immediately... Immediate implantation is possible. The dental implant prosthesis can be inserted into the extraction socket by percussion, and the serrated edge of the implant 5 allows the dental implant prosthesis to be inserted into the alveolar bone and fit tightly with the alveolar bone, achieving better initial stability in the fresh alveolar socket after tooth extraction and achieving reliable retention. At the same time, the implant 5 adopts a thin and wide blade structure design. Its flat shape has a smaller diameter and volume compared to traditional cylindrical implants, which can be used in narrow implant areas. In the traditional dental implantation process, cylindrical implants are limited by their insufficient width and require bone augmentation first. However, bone augmentation is more complex and prone to complications, thus reducing the success rate of implantation. The use of the serrated edge of the implant 5 simplifies the operation and improves the success rate of dental implantation. When the dental implant prosthesis is a one-piece prosthesis, the prosthesis 3, abutment 2, and implant 1 are integrated into a single structure. Patients only need one procedure to insert the implant 1 into the extraction socket. The abutment 2, with its side near the prosthesis 3 flush with the gingiva or exposed outside the gingiva, acts as an artificial crown, exposed in the oral cavity. No secondary surgery is required to install the dental implant prosthesis. When the dental implant prosthesis is a two-piece external interface prosthesis, patients need two procedures. The first procedure inserts the implant 1 and abutment 2 into the extraction socket, with the serrated edge of the implant 5 closely fitting the alveolar bone to secure the implant 1 and abutment 2. The end of abutment 2 furthest from the implant 1 is flush with the gingiva or exposed outside the gingiva. The second procedure connects the prosthesis 3 to the abutment 2, thus completing the implantation.

[0032] In this invention, the serrated edge of the implant 5 includes a plurality of serrated units 6; the distance between any two adjacent serrated units 6 is 0.2mm-0.5mm.

[0033] In some embodiments, such as Figure 2 , Figure 4 As shown, whether it is a one-piece dental implant prosthesis or a two-piece external interface dental implant prosthesis, the serrated edge of its implant 5 includes multiple serrated units 6, for example, five, and the spacing between any two adjacent serrated units 6 is the same, which can be 0.2mm-0.5mm. By setting multiple serrated units on the serrated edge of the implant, it is easier for the dental implant prosthesis to be inserted into the alveolar bone and to achieve close fit with the alveolar bone, increasing the bone contact area, improving the initial stability of the dental implant prosthesis after implantation, and helping to improve the success rate of dental implantation.

[0034] In other embodiments, the number of sawtooth units 6 can be set according to actual conditions.

[0035] In this invention, each sawtooth unit 6 includes an inclined surface 7 and a plane 8; the end of the inclined surface 7 near the plane 8 is connected to the end of the plane 8 near the inclined surface 7.

[0036] In some embodiments, such as Figure 2 , Figure 4 As shown, each sawtooth unit 6 includes an inclined surface 7 and a flat surface 8, and the inclined surface 7 is inclined towards the fixed component. Figure 2 or Figure 4 In the middle view, plane 8 is a plane set in the vertical direction. In the actual planting process, ideally, plane 8 can be set in the horizontal direction. The end of plane 8 near the inclined plane 7 is connected to the end of plane 8 near the inclined plane 7. In each sawtooth unit 6, the end of plane 8 away from the inclined plane 7 is also provided with another plane 8. Assuming that sawtooth unit A and sawtooth unit B are two adjacent sawtooth units 6, sawtooth unit A includes inclined plane a1 and plane a2, and sawtooth unit B includes inclined plane b1 and plane b2. The end of plane a2 away from inclined plane a1 is connected to plane c. Plane a2 is perpendicular to plane c. The end of plane c away from plane a2 is connected to the end of inclined plane b1 away from plane b2. Therefore, plane a 2. The plane c and the inclined plane b1 are connected to form a conical fin. For example, each implant 5 can be provided with 4 fins, and the fins are relatively thin, for example, 0.3mm-0.8mm, to facilitate insertion into the alveolar bone. During the implantation of the oral implant prosthesis, by setting the serrated unit including the inclined plane and the plane, the fin is formed, so that the fins on the serrated edge of the implant can open the bone on both sides of the patient's extraction socket, providing more space for implantation. During the healing process after implantation, the bone will also grow into the groove along the serrated edge of the implant, similar to an inverted form, to fix the oral implant prosthesis and prevent it from falling out.

[0037] In this invention, the side of the implant 5 away from the serrated edge is the groove edge; the side of the inclined surface 7 near the plane 8 is provided with a first through hole 9; the first through hole 9 is parallel to the plane 8; the side of the first through hole 9 near the inclined surface 7 penetrates the inclined surface 7; the side of the first through hole 9 away from the inclined surface 7 penetrates the groove edge.

[0038] In some embodiments, such as Figure 2 , Figure 4 As shown, the side of the implant 5 away from the serrated edge is the groove edge. Each inclined surface 7 has a first through hole 9 on the side near its corresponding plane 8. The first through hole 9 is parallel to the plane 8. The number of first through holes 9 can be the same as the number of inclined surfaces 7, for example, 5. The side of the first through hole 9 near the serrated edge penetrates the serrated edge, and the side of the first through hole 9 near the groove edge penetrates the groove edge. During the healing process after implantation, bone will grow into the first through hole to achieve fixation, enhance the stability of the oral implant prosthesis in the extraction socket, and improve the success rate of dental implantation.

[0039] In other embodiments, the number of first through holes 9 can be set according to actual conditions.

[0040] In this utility model, an arc-shaped groove 10 is provided on the side of the first through hole 9 away from the inclined surface 7; the arc-shaped groove 10 bends toward the fixing component.

[0041] In some embodiments, such as Figure 2 , Figure 4 As shown, an arc-shaped groove 10 is provided on the side of the first through hole 9 away from the inclined surface 7. In fact, the arc-shaped groove 10 is provided on the edge of the groove of the implant 5, and the number of arc-shaped grooves 10 can be the same as the number of the first through holes 9. For example, it can be 5. The arc-shaped groove 10 bends towards the fixing component. By providing an arc-shaped groove on the edge of the groove of the implant, and the arc-shaped groove communicating with the first through hole, the surface area and bone contact area of ​​the oral implant restoration are increased, which improves the osteogenesis effect. After healing, the bone grows into the arc-shaped groove, which enhances the stability of the oral implant restoration in the extraction socket. At the same time, the design of the arc-shaped groove reduces the weight of the oral implant restoration to a certain extent.

[0042] In other embodiments, the number of first arc-shaped grooves 10 can be set according to actual conditions.

[0043] A second through hole 11 is provided between the serrated edge and the groove edge; the second through hole 11 is perpendicular to the first through hole 9.

[0044] In some embodiments, such as Figure 2 , Figure 4As shown, a plurality of second through holes 11 are provided between the serrated edge and the groove edge, and the second through holes 11 are perpendicular to the first through hole 9; the second through holes 11 can be circular or elliptical, that is, circular or elliptical second through holes 11 are provided on the surface of the implant 5, and the second through holes are used as blood supply holes or weight reduction holes in actual use, for example, as shown in... Figure 2 , Figure 4 As shown, one round hole and two oval holes can be set, but in actual use, the setting can be adjusted according to the actual situation. By setting a second through hole on the surface of the implant, the weight of the dental implant restoration is reduced to a large extent and the blood supply is increased. After the patient heals, the bone will also grow into the second through hole, which enhances the stability of the dental implant restoration in the extraction socket.

[0045] In this invention, the implant 1 further includes an implant neck 12; the implant neck 12 is disposed between the implant body 4 and the abutment 2; the side of the implant neck 12 near the implant body 4 is fixedly connected to the implant body 4; the side of the implant neck 12 near the abutment 2 is fixedly connected to the abutment 2.

[0046] In some embodiments, such as Figure 2 , Figure 4 As shown, due to the different target groups for dental implants, the size of the implant 1 needs to be determined based on the oral environment of different target individuals, namely the width and height of the alveolar bone, the location of the missing teeth, and the biting force. For example, if the missing teeth of the target individual are in the anterior region, then a smaller diameter implant 1 can be selected, that is, a smaller diameter fixation component can be selected, and the width of the implant 5 can also be appropriately reduced accordingly. If the missing teeth of the target individual are in the posterior region, then since the posterior teeth bear greater biting force, a larger diameter and longer implant 1 can usually be selected, that is, a slightly larger diameter fixation component can be selected, and the length of the fixation component can also be appropriately increased. At the same time, the implant 1 also includes an implant neck 12, which is located between the implant body 4 and the abutment 2, and the implant neck 12, implant body 4, and abutment 2 are connected as a whole. The implant neck 12 is the part of the implant 1 that is close to the patient's gums. It is used to separate bone tissue and soft tissue, and at the same time provides the basis for the connection of the abutment 2 to prevent bacteria from invading the area around the implant 1. By setting up an integrated abutment, implant neck, and implant body, the implant and abutment can be inserted at once during the implantation process, simplifying the implantation procedure.

[0047] In this invention, the implant 1 further includes an implant head 13 of a preset shape; the implant head 13 is disposed on the side of the implant body 4 away from the implant neck 12; the side of the implant head 13 close to the implant body 4 is fixedly connected to the implant body 4.

[0048] In some embodiments, such as Figure 2 , Figure 4 As shown, the preset shape can be spherical. The implant 1 also includes a spherical implant head 13 or a similar spherical implant head 13. The implant head 13 is located on the side of the implant body 4 away from the implant neck 12, and the implant neck 12, the implant body 4 and the implant head 13 are connected as a whole. The implant head 13 refers to the part located at the front end of the implant 1. The spherical implant head can play a guiding role, preventing the dental implant restoration from shifting from the tooth socket formed after tooth extraction during the percussion implantation process, enhancing the initial stability of the dental implant restoration after implantation, and achieving firm positioning of the dental implant restoration.

[0049] In this invention, a groove 14 is provided on the side of the abutment 2 away from the neck 12 of the implant; a connecting joint is provided on the side of the prosthesis 3 close to the abutment 2; the shape of the connecting joint matches the shape of the groove 14; the connecting joint and the groove 14 are detachably connected.

[0050] In some embodiments, such as Figure 2-7 As shown, regardless of whether it is a one-piece or two-piece external interface dental implant prosthesis, all dental implant prostheses have a groove 14 on the side of the abutment 2 away from the implant neck 12, and all prostheses 3 have a connecting connector on the side near the abutment 2. The shape of the connecting connector matches the shape of the groove 14. The connecting connector is inserted into the groove 14, thereby connecting the prosthesis 3 to the abutment 2. In addition, the shape of the groove 14 of the abutment 2 is different in different dental implant prostheses 3. For example, in a one-piece dental implant prosthesis, the shape of the groove 14 can be circular. Figure 3 This is a cross-sectional view of the abutment on the side closest to the prosthesis in a one-piece dental implant restoration. Figure 3 There are three circles in the middle. The outermost circle is the cross-sectional shape of the base 2 as a whole, and the middle circle is the circular groove set on the base 2. Figure 6 This is a cross-sectional view of the abutment near the prosthesis in a one-piece dental implant restoration after healing. Figure 6 The obliquely lined area represents the patient's alveolar bone, and the mesh area represents the bone ingrowth zone after healing. In the two-segment external interface implant restoration, the shape of groove 14 can be hexagonal, rectangular, or other shapes. Figure 5This is a cross-sectional view of the abutment near the prosthesis in a two-segment external interface implant prosthesis. Figure 5 The outermost circle represents the overall cross-sectional shape of base 2, while the inner outer hexagons are the hexagonal grooves provided on base 2. Figure 7 This is a cross-sectional view of the abutment 2 near the prosthesis 3 in a two-segment external interface implant restoration after healing. Figure 7 The oblique lines represent the patient's alveolar bone, while the grid area represents the bone ingrowth zone after healing. By setting grooves of different shapes on the abutment, the dental implant prosthesis can achieve fixation and anti-rotation without relying on increased torque during implantation. This avoids bone compression caused by screws on the alveolar bone during conventional implant torque tightening, which affects the healing speed. It also helps the prosthesis and abutment to connect, enhances the stability of the dental implant prosthesis after implantation, and successfully achieves dental implantation.

[0051] In this utility model, the connecting joint includes a first connecting joint and a second connecting joint; the first connecting joint and the second connecting joint are fixedly connected; the first connecting joint is disposed between the second connecting joint and the base 2; the shape of the first connecting joint matches the shape of the groove 14; the first connecting joint is engaged with the groove 14; a fastening part 15 is sleeved on the outer side of the second connecting joint; the second connecting joint is movably connected with the fastening part 15.

[0052] In some embodiments, the fastening part 15 can be a screw, and the connecting joint includes a first connecting joint and a second connecting joint, which are fixedly connected. The first connecting joint is disposed between the second connecting joint and the base 2, and the shape of the first connecting joint is the same as that of the second connecting joint. In effect, the connecting joint is divided into two parts, namely the first connecting joint and the second connecting joint. The first connecting joint is inserted into the groove 14 of the base 2, and then the repair body 3 is connected to the base 2 by means of the fastening part 15 sleeved on the outside of the second connecting joint. Figure 3 The innermost circle is a cross-sectional view of the fastening component fitted onto the second connector of a one-piece dental implant prosthesis. Figure 5 The circle inside the hexagonal groove is a cross-sectional view of the fastening component fitted onto the second connecting joint of the restoration in a two-stage external interface cavity implant restoration. By setting grooves of different shapes and connecting joints, an anti-rotation connection between the restoration and the abutment is achieved, ensuring that there is no relative rotation between the restoration and the abutment, improving the connection stability between the restoration and the abutment, and helping to achieve precise alignment of the restoration, thus increasing the success rate of dental implantation.

[0053] The working principle of this dental implant prosthesis is as follows:

[0054] When a patient needs a one-piece dental implant prosthesis, after the patient has a tooth extracted, the dental implant prosthesis is hammered into the extraction socket. The serrated edge of the implant 5 is inserted into the alveolar bone and fits tightly with the alveolar bone. During the patient's healing process, the bone grows into the arc-shaped groove 10 along the first through hole 9 and into the second through hole 11, achieving a tight fit between the one-piece dental implant prosthesis 3 and the alveolar bone.

[0055] When a patient requires a two-segment external interface cavity implant restoration, after tooth extraction, the implant 1 and abutment 2 of the oral implant restoration are hammered into the extraction socket, and the serrated edge of the implant 5 is inserted into the alveolar bone, fitting tightly with the alveolar bone. During the healing process, the bone grows into the arc-shaped groove 10 along the first through hole 9 and into the second through hole 11, achieving a tight fit between the implant 1 and abutment 2 and the alveolar bone. After healing, a second surgery is performed to connect the restoration 3 and abutment 2 with anti-rotation, thus successfully implanting the two-segment external interface cavity implant restoration.

[0056] The beneficial effects of this utility model are:

[0057] This utility model discloses an oral implant prosthesis, comprising an implant, an abutment, and a prosthesis; the abutment is disposed between the implant and the prosthesis; the side of the abutment near the prosthesis is detachably connected to the prosthesis; the side of the abutment near the implant is fixedly connected to the implant; the implant includes a fixation component and an implant body; the implant body is fitted onto the outer surface of the fixation component; the implant body includes multiple implants; the multiple implants are evenly distributed along the central axis of the fixation component; each implant is fixedly connected to the fixation component; the side of the implant near the fixation component is fixedly connected to the fixation component; the side of the implant away from the fixation component has a serrated edge. By designing an implant with serrated edges, a percussion placement method was achieved, facilitating the insertion of dental implants into the alveolar bone. This simplified the cavity preparation process in dental implant surgery, avoided complex bone augmentation, and expanded the clinical indications. The spherical implant head improved the success rate of the implant surgery. By incorporating a second through-hole and a groove edge with an arcuate groove on the implant, the weight of the implant was reduced, facilitating bone ingrowth into the second through-hole and the arcuate groove after healing, and improving the stability of the dental implant after implantation.

[0058] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
