Description

FIELD FIXTURE COMPRISING ARTIFICAL TEETHRIDGE AND FANG}

The present invention relates to an artificial tooth fixture including an artificial alveolar and a tooth root, an artificial toothridge of an integral structure fixed to a cortical bone of an alveolar bone, in particular, It's about fangs. The artificial alveolar and tooth roots can be well distributed to the alveolar bone by dispersing the chewing force (cheongryok) well, it may be applied to the entire upper surface of the alveolar bone.

Today, there are various ways to embed dentures. The initial method is to insert dentures directly into the gums. The method is very simple, but usually the patient has an unpleasant feeling of having a foreign body in the mouth, there is a problem that can not chew hard food, other disadvantages are that it is difficult to fix the denture on the jaw bone and always cause gingivitis There is a problem.

Another method is to implant a fixture in the jawbone, a so-called "dental implant" commonly used today. The method is disclosed in prior patents such as US Pat. No. 4,359,318, US 6322364, US 5542847, US 6916177, US 5306149, US 6991463, US 3925892, US 4722687, US 4344757, US 4964801, US 6655962 and the like. The fundamental problem of the aforementioned methods is the chewing force on a single implant. In addition, the implant is anchored to the alveolar bone of the dense network of small density and hardness. Thus, it has a limited capacity of loading force. If the alveolar bone is seriously lost, the implant will be impossible or fail, such a result being due to the alveolar bone having a height and width not sufficient for the implant. Even with diarrhea implants, the twisting and shear forces during chewing will cause the implant to loosen or cause alveolar damage. In addition, the methods described above have to wait about six months before the alveolar bone is infused with the implant, resulting in the patient having to withstand long chewing problems before the denture is fully settled. have.

In addition, some of the implanted fixtures have a mounting structure, such as a U type, saddle type, covering type, etc., and other implanted fixtures. These have auxiliary structures such as loops, plates, washers, shoulders, and the like, and are registered in US Pat. Nos. US 5906489, US 4702697, US 5052930, US 5513989, US 3579829, US 4121340, US 4379694, US 4531916, US 5201736, US 5759033, US 5944526, US 6287118, US 6991463, US 4728331, US 4321914, US 4531916, US 4253833, US 5573401, US 6250923, US 6273720, US 4073999, US 6287118, US 5769637, US Patent Publication 2006/0154205 A1, France Patent FR 1113889, Russian Federation Patent RU 2217097, RU 2145819, Bulgaria Patent BG 51338, International Publication WO 2002/39921, WO 2008/062256 and China Patent Registration The implanted fixtures described above are disclosed in CN 1537516 (200310101638.6). Although the aforementioned implanted fixtures have a mounting or accessory design that is different from a single implant, they all focus on the problem of anchoring and still maintain the main force on the implant. This takes The two types of structures described above are not mechanically conductive structures that are relatively thick in the middle and gradually thinner toward both sides, and are not mechanically supported structures with complementary structures that allow them to be closely fixed to the upper surface of the cortical bone of the alveolar bone. Thus, the structures described above are not only able to disperse and distribute chewing power uniformly, but also to impart chewing force on the robust cortical bone surface of the alveolar bone. Since most of these patents still cause implants to be anchored to alveolar bone or some prominent points of the cortical bone of the less dense reticulated tissue, the structures not only have an area that is not sufficient to entrain the alveolar bone, It is not possible to distribute the chewing power uniformly. Thus, it still has the disadvantage of being easily damaged. Moreover, most of these structures are not integral designs and therefore not only brittle, but also have poor conducting power.
Other designs, such as DE 20200601134 0U and WO 2000/01318 A1, disclose a general implant fixture that is secured to the alveolar bone. These patents are not mechanical conduction structures or mechanical support structures that distribute the loading force evenly or allow the chewing force to be caught in the cortical bone of the alveolar bone.

The conclusion of the above-mentioned prior patents is that most implants on the market today still focus on how to secure the implant. Since all occlusal pressure, torsional force and shear force on prosthesis in the chewing process can not be distributed and transmitted to the outside, it is necessary to provide a better fixation method and a strong structure that requires chewing force. While the prior art described above focuses on how to secure the implant firmly to the alveolar bone, most designs secure it to the alveolar bone of the dense reticular tissue rather than the strong cortical bone of the alveolar bone. The above designs neglect the problem of how to balance the chewing power in a balanced and even manner, resulting in alveolar damage and alveolar atrophy of the residual alveolar ridge. Overlooked.

All the prior patents mentioned above focus only on the structure of a single prosthesis. Other designs that disclose the structure of a full denture are described in US Patents US 4225668, US 4741698, US 4767328, US 5098296, US 6382975, US 6685473, US 6692254, US 7234940, and the like. These include several single implants that are inserted into the alveolar bone and then connect the implants to the top of the gum with a bar or bridge structure. The bar or leg structure forms a supporting structure to hold the total denture. Although the patents have structures that distribute the writing power well, there is still a problem that the writing power is applied to several single implants. These designs still have the same disadvantages as the single implants mentioned above, namely that they have a limited loading force as the implant is secured to the alveolar bone of a dense network of small density and hardness, It also has the problem that it cannot be implanted into atrophic alveolar bone with insufficient height and width. Even if the implant is made, the torsional and shear forces will cause the implant to loosen or cause alveolar bone damage. In addition, you have to wait about six months for the alveolar bone to coalesce with the implant.

In addition, US Patent US 2836890 discloses a structure of a total denture fixed to the surface of the alveolar bone, but the bottom portion of the structure is not a complementary structure that can be tightly fixed to the upper surface of the alveolar bone without gaps. The structure is still subject to chewing force at some protrusions on the alveolar bone surface, which will lead to alveolar bone damage and alveolar atrophy at the protrusions on the alveolar bone and will loosen the implant. In addition, the total denture is not a unitary structure and still secures all dentures with screws. That is, because the structure is fragile and the transfer of chewing force is discontinuous, the bite, torsional and shear forces will loosen the screws. Most importantly, the structure does not have tapered posts and crescent-shaped carriers. That is, it is not a mechanical conduction structure capable of distributing the loading force uniformly and delivering it uniformly, so that the transfer of the loading force is not uniform and the capacity of the loading force is poor.

U.S. Patent No. 4379694 discloses an arch fixture-shaped dental fixture. The structure is mounted on the alveolar bone, but the main structure is a flat metal plate with no tapering ends, the metal plate being relatively thick in the middle and not gradually thinning toward both sides. That is, it is not a mechanically conductive structure that can uniformly deliver the load by distributing it. Moreover, it is not an integrated structure. The structure thus requires screws to firmly fix the leg or denture to the strut head with threaded holes. Although the structure enhances the fixing function, it is still unable to transmit and distribute the chewing power, and is also a weak structure.

Most importantly, for all the prior patents mentioned above, the bottom surface of the artificial tooth structure is lacking as a complementary structure that can be tightly fixed to the top surface of the alveolar bone without gaps. All the above-described artificial tooth structures cannot distribute the chewing force uniformly at each point on the surface of the alveolar bone, and the structures still apply chewing force to some protruding points of the alveolar bone surface, resulting in alveolar bone damage and alveolar bone atrophy. This will lead to loosening of the implants. In conclusion, the structures according to the above-mentioned prior patents were not designed as a mechanically conductive structure with the function of a "raft foundation", without the fact that in the early days it was difficult to obtain an accurate model of the alveolar bone. It is also due to the fact that it was also difficult to produce artificial teeth having complementary structures that could be tightly fixed to the upper surface of the alveolar bone. Today, however, related technologies such as 3D photography, computer aided design (CAD), computer numerical control (CNC) fabrication, and injection molding have been developed to fully complement the alveolar bone surface. It is not difficult to make an accurate artificial tooth with a surface. In addition, it is also not a problem to make a mechanically conductive structure that is fixed to the surface of the alveolar bone, and as a result, the loading force transmitted from the denture can be distributed through the unitary structure and transmitted completely uniformly to each point on the alveolar bone surface. Therefore, there is no longer a problem of chewing power in the hard cortical bone of the alveolar bone.

In order to deal with the above-mentioned problems, the applicants correspond to the application number PCT / CN2007 / 000353, entitled “Denture Carrier Fixed on The Surface of The Alveolar Bone”. Filed a PCT international application. Furthermore, in order to make the product more complete and to pursue excellent technological innovation, the present patent application has been further filed.

The main object of the present invention is to provide a structure of artificial teethridge and fang, which has a large capacity of loading force and is capable of uniformly and stably transmitting chewing force. To design. In order to achieve the above object, the present invention designs a structure having an arcuate top and bottom surface. The top and bottom surfaces are bent in the same direction, and the thickness is relatively thick at the center and gradually thinner toward both sides. The root is installed on the upper surface, the upper part is narrow and the bottom part is wide. A denture (prosthesis) is mounted on the root, and the chewing force transmitted from the denture is transmitted to the entire upper surface of the alveolar bone through the above-described structure. Thus, the chewing force will be distributed and transferred from the upper surface of the narrow roots to the surface wider alveolar bone. This mechanical conduction structure can evenly distribute and transmit chewing power.

In addition, the bottom surface of the artificial alveolar is designed in a complementary structure that can be tightly fixed to the upper surface of the alveolar bone without gap (that is, the bottom surface of the artificial alveolar is a concave surface matching with the convex surfaces of the alveolar bone). Or convex surfaces that are matched with the concave surfaces of the alveolar bone, the convex surfaces and the concave surfaces being complementary to each other, that is, the bottom surface of the artificial alveolar bone Has a complementary structure in close contact with the upper surface). Through a complementary arrangement as described above, the loading force delivered from the denture can be distributed to uniformly deliver the chewing force to each point on the surface of the cortical bone of the alveolar bone. The structure described above has a mechanical support function, such as the "raft foundation" of architecture, so that the chewing force transmitted from the denture is evenly applied to each point on the upper surface of the alveolar bone. Since the present invention uses the "raft foundation" instead of the "pile foundation" as in the prior art, it is possible to make the chewing force uniform and stable as described above. In other words, this mechanical support structure can make the chewing force completely and evenly applied.

Also, to avoid the presence of a weak point in the dental structure, the present invention does not allow the individual members to be joined by screws. Thus, there is no connection that causes discontinuous transmission of masticatory force and reduces the ability to transmit. The present invention is designed as a unitary structure including the main part for transmitting and supporting the chewing force, thereby forming a strong and stable structure capable of large force support, uniform force distribution, solid fixation and excellent force transmission.

The present invention has the three main features described above which are not found in any prior art. Each of the independent claims (such as claims 1, 8, 14, 20, 26, 28, and 30) of the present invention has at least one of the three main features described above. . A summary of the three main features described above is as follows:

1. The artificial tooth structure according to the present invention is formed of artificial alveolar and tooth root, the tooth root is narrow in the upper part and wide in the bottom part, the thickness of the artificial alveolar is relatively thick in the center and gradually thinner toward both sides. In particular, the structure is a mechanically conductive structure that can transmit and distribute the loading force uniformly downward.

2. The bottom surface of the artificial alveolar has a complementary structure that can be tightly fixed to the top surface of the alveolar bone without a gap, whereby the bottom of the artificial alveolar forms a mechanical support structure. Through the complementary arrangement described above, the loading force transmitted from the root can be distributed and evenly transmitted to each point of the upper surface of the alveolar bone. That is, "raft foundation" is used instead of "pile foundation" so that the chewing force is uniformly applied.

3. The above-described artificial alveolar and tooth root structures are in particular a unitary structure in which no part is decomposed, and therefore do not cause a weak structure and insufficient force transmission.

All three of the above-described features of the present invention may be designed to be included in one product or may be designed to include any one feature. In addition, a single product may be designed to include two of the aforementioned features.

As shown in FIGS. 1 and 2, the present invention according to the first preferred embodiment includes an artificial teethridge 10, a prosthesis base 20 and a prosthesis 30.

The artificial alveolar 10 has a crescent-shaped cross section that is shaped to correspond to a human maxillary or mandible, and its thickness is relatively thick in the middle and gradually thinner toward both sides. The artificial alveolar 10 has an arcuate top surface 11 and a bottom surface 12. The upper surface 11 of the artificial alveolar 10 is provided with a tooth root (fang: 13), the tooth root 13 has a narrow upper portion, the bottom portion is wide. The bottom surface 12 of the artificial alveolar 10 is designed in a mutually complementary structure that can be tightly fixed to the top surface of the alveolar bone 5 without gaps, and thereby the bottom surface of the artificial alveolar 10 12 forms a mechanical support structure. The loading force transmitted from the denture 30 may be distributed through the above-described structure and uniformly transmitted to each point of the cortical bone 4 so that the chewing force is strong. It can be caught in the cortical bone (4). In addition, a fastening fixture 14 is installed on the bottom 12 of the artificial dental clinic 10.

In the above embodiment, the fixing fixture 14 has lateral flanges 15 around and an enlarged portion for forming a lock portion 16 at the distal end. Have The fixture 16 may be replaced with another frictional structure, such as a loop, punctate structure or toothed structure.

The denture base 20 has an arcuate shape and may be complementary to the artificial alveolar 10. The denture base 20 has stakes 21 for mounting the denture 30 on its top surface. The dentures 30 are connected to each other by an artificial gingival 31 to look natural. The denture base 20 has a cavity 22 corresponding to the tooth root 13 on the upper surface 11 of the artificial alveolar 10. In the actual procedure, there is also a method in which the denture 30 is directly mounted on the tooth root 13 without the denture base 20.

The denture 30, artificial gum 31, and denture base 20 are combined into a denture set, which is later mounted to the artificial alveolar 10. There is a gap formed between the bottom of the denture set and the top surface 11 of the artificial alveolar 10 to receive a gingival 6. If necessary, as shown in FIG. 2, the screw 25 is tightened to strengthen the engagement of the denture set with the tooth root 13.

In this embodiment, prior to installing the artificial alveolar 10, positioning holes must be formed in the alveolar bone 5 in advance, and the holes are later replaced by bone tissue of the patient. Filled with degradable biodegradable bone cement or other similar materials. Since the fixing portions 16 of the fixture 14 have a relatively large size, the fixing fixture 14 will be fixed when the biodegradable bone cement is hardened or replaced with a patient's newly grown bone tissue. . Accordingly, the artificial alveolar 10 will be firmly fixed to the alveolar bone 5.

Unlike conventional structures that focus only on how the implant can be secured to an oversized cancellous bone, the present invention relates to an artificial alveolar 10 and a tooth plant that are fixed to the surface of the alveolar bone 5. The structure of the li 13 is designed. The root portion 13 has a narrow upper portion, a wide bottom portion, and the thickness of the artificial alveolar 10 is relatively thick in a central portion, and gradually thinner toward both sides. That is, the artificial alveolar 10 and the tooth root 13 form a mechanically conductive structure. Thus, the chewing force delivered from the denture can be further transmitted downward and outward through the structure described above. The bottom 12 of the artificial alveolar 10 is designed with a mechanical support structure and has the same function as the so-called "raft foundation" of architecture. Therefore, the chewing force transmitted from the denture is uniformly applied to the entire cortical bone 4 surface of the alveolar bone 5 through the above-described structure. Since there is a wide area for uniform chewing force, the above-described structure is very strong, and has a large capacity for receiving chewing force. As a result, the denture 30 can perform as much as natural teeth do, and allow chewing of hard foods. In addition, since the alveolar bone 5 has a long-term loading force with a uniform and wide area, alveolar bone atrophy is impossible.

Even if the patient has severe alveolar bone atrophy or osteoporosis and the alveolar bone 5 has an insufficient width, the artificial alveolar 10 is fixed to the alveolar bone 5 and the sturdy cortical bone 4 so that the artificial alveolar 10 ) And tooth root 13 can still be implanted and later mounted with denture 30 on tooth root 13. In addition, since the fixing method is to mount the artificial alveolar 10 and the tooth root 13 on the cortical bone 4, unlike the prior art, the treatment period can be reduced. In order to allow the alveolar bone to coalesce with the conventional implant, it takes about a week, not six months, to heal the wound on the gum 6, since the denture set can later be mounted on the tooth root 13, The duration of treatment is significantly shorter.

3 shows a second preferred embodiment, the main structure of which is a transverse screw in the fixing fixture 14 to enhance the rigidity of the artificial alveolar 10 mounted to the alveolar bone 5. Same as the first preferred embodiment described above, except that screw 17 is fastened. The transverse screw 17 need not be fastened to all fastening fixtures 14. In practice, only three to five transverse screws 17 are required for the entire artificial tooth fixture including the artificial alveolar 10 and the tooth root 13.

4 shows a third preferred embodiment, in which the main structure of the embodiment is that a pair of fixation fixtures 14 are installed on the bottom 12 of the artificial alveolar 10 and the pair of fixations Similar to the second preferred embodiment described above, except that the transverse screw 17 is fastened between the fastening fixtures 14. This embodiment has the same function as the previous embodiment.

5 shows a fourth preferred embodiment, the main structure of which is that the artificial alveolar 10 does not have any fixation fixture 14 on the bottom 12 and the fixation fixture described above ( 14) Instead of fixing the artificial alveolar 10 to the upper surface of the alveolar bone 5 using a fixing screw 14 (screw type fixing fixture, that is, the fixing screw is another form of the fixing fixture). Except for that, it is similar to the first preferred embodiment described above.

6 shows a fifth preferred embodiment, the main structure of which is similar to the fourth preferred embodiment described above, with a pair of fastening screws 14 in which the artificial alveolar 10 faces each other. It is fixed to the alveolar bone (5).

In the fifth preferred embodiment described above, the artificial alveolar 10 is mounted directly to the cortical bone 4 of the alveolar bone 5. Therefore, the patient has severe alveolar bone atrophy or osteoporosis so that the nerve cavity 3 is too close to the upper surface of the alveolar bone 5 and the width and height of the alveolar bone 5 are not sufficient to implant the fixture to mount the denture. If it is not enough, since only the width and height of the artificial alveolar 10 is adjusted according to the width and height of the alveolar bone 5 of the patient, as shown in Figure 7, the worry of damage to the nerve (3) It is still possible to install fixtures without artificial teeth.

Although there are some differences between the above-described embodiments, the main structure is the same. All the above-described artificial tooth fixtures have a mechanically conductive structure with a narrow top and wide bottom roots and a crescent-shaped carrier to distribute the chewing force evenly. In addition, the above-described artificial tooth fixtures have a mechanical support structure that uses a "raft foundation" instead of a "pile foundation" to take the chewing force and increase the capacity of the loading force. In addition, the above-described artificial tooth fixtures may integrate the artificial alveolar 10, the tooth root 13, the fixing fixture 14, and the denture 30 to form an integrated structure. As a result, the chewing force can be made uniform, and it can have a large capacity of bearing capacity and a rigid structure.

In addition to the above-described embodiments, the artificial alveolar 10 is integrated into the human body, as shown in FIG. 8, to facilitate the healing of the gum 6 and to ensure that the mounted artificial alveolar 10 is fully secured. Through-holes 18 are provided in the artificial alveolar 10 to facilitate this.

In addition, in order to enhance the stability of the artificial alveolar 10, a recess 19 having a narrow opening as shown in FIG. 9 is provided in the bottom 12 of the artificial alveolar 10. The newly growing bone tissue will enter the recess 19 of the artificial alveolar 10 and will enhance the firmness of the artificial alveolar 10. In addition, a concave loop 131 is provided around the root 13, and a convex loop 211 corresponding to the concave loop 131 is provided in the cavity 22 of the denture base 20. ) Is provided on the inner wall. Furthermore, a cushion pad 40 is secured to the upper surface of the tooth root 13 to buffer the chewing force acting on the denture set so that it is further transmitted to the tooth root 13.

10 shows the fastening screw 14 of the fourth, fifth and seventh preferred embodiments, which may be a general screw or a circular screw with a fastening 16. The fixing screw 14 has a flat end and a threaded section, and a plurality of through holes 141 are formed in the end and the thread. The flat end and the through holes 141 form a fixing part. The function of the fastening screw 14 having the fastening portion is to fasten the fastening screw 14 to the artificial alveolar 10. Prior to fixing the fixing screw 14, the positioning holes are filled with the biodegradable bone cement described above, and the hardened biodegradable bone cement will be decomposed and replaced with freshly grown bone tissue. The newly grown bone tissue may also be made by osteoadhesion without biodegradable bone cement. The biodegradable bone cement or the newly grown bone tissue hardened in the periphery of the flat end and the through holes 141 secures the fixing screw 14 to prevent the fixing screw 14 from rotating or loosening. Will form.

In addition to the above-described embodiments, other embodiments may be made without departing from the scope of the present invention.

The present invention provides a unitary structure of artificial teethridge and fang (and optionally prosthesis), the scope of which is for single, partial and fully-arched artificial teeth, partial and full-arched dental fixtures.
