New description: [New technical field] This creation is related to artificial teeth, especially one-time implantable artificial tooth with immediate function. 5 [Prior Art] Traditional edentulous restoration methods can be roughly divided into four categories (A). Two-stage intraosseous osseointegration implant edentulous restoration is the most common implant, usually in many previous patents. Cases such as US Patent Nos. 6322364, 6916177, 6991463, and 10 6655962 have all been disclosed in detail. This kind of edentulous restoration needs to be sutured after implanting the implant, suspending the gums, embedding the implant under the gums, allowing the implant 1 to integrate with the alveolar bone, and then cutting the gums to connect the abutment 2 after 4 to 6 months. The implant is exposed in the mouth, and the gums are sutured again. After the gums are healed, the mold is taken, and then the artificial teeth are loaded to complete the operation of the entire 15 missing teeth. The advantage of this method is that the implant bone is well combined and is not susceptible to infection. The long-term effect is good and the success rate is high. As shown in the first figure A. (B) · The edentulous restoration of the staged intraosseous osseointegration implant combines the implant 1 and the abutment 2 into one body. When the knife is opened, the abutment is exposed in the oral cavity. 'After 4 to 6 weeks, the implant is stabilized. , take the mold and complete the final restoration. As disclosed in U.S. Patent Nos. 6,981,873, 6,880,707, 6,746,244, 6,732,291, and 7,207,800. This type of implant receives a certain range of stress in the alveolar bone. It can be used to install temporary dentures with no functional immediate load for aesthetic purposes. After waiting for osseointegration for about two months, replace the -4- M355092 with the mold. Formal dentures. The advantage of this approach is that it is reduced as shown in Figure B. Once the knife is opened, it has a beautiful effect. (6) · Subperiosteal _ body missing teeth repair 5

As shown in the second figure B. (D). There is a U-shaped or saddle-shaped, covered type with a straddle structure, or I5 has an edentulous restoration of an implant with an auxiliary member such as a lip, a flange, and a shoulder. For example, U.S. Patent Nos. 5,906,489, 4,702,697, 5,529,930, 5,513,989, 4,121,340, 4,379,694, 5,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, The artificial root has different cladding or auxiliary design than the pile. The overall structure focuses on the fixed problem. The advantage is that the dispersed part can be stressed on the cortical bone and can improve the stability of the pile. The second figure A shows one of them. M355092 All of these predecessors have their own advantages, but they all have the following problems or shortcomings: ^ 1. Patients need to undergo multiple operations and lengthy and complicated repair procedures. General implants need to produce bone with alveolar bone. After the integration, and then the town of the United States to make a denture 'final to complete the upper repair. Tudou clothing is composed of implants, abutments, crowns, screws, etc. It requires multiple operations and lengthy and complicated procedures. The patient suffers from physical and mental pain. , causing considerable inconvenience and embarrassment. 10 15 20 Although the edentulous restoration of the one-stage intraosseous osseointegration implant can reduce the number of ruptures, it still requires lengthy and complicated procedures. 2. Lack of immediate load and immediate occlusion. Intraosseous osseointegration implants must be osseointegrated under no-load conditions. Premature force can cause osseointegration failure, so it is necessary to implement Anzhen earthquake in stages. Patients must endure for a long time without Inconvenient function. Although some of the one-stage intraosseous osseointegration and edentulous restorations can be used to install non-functional temporary dentures for aesthetic purposes. However, it is difficult to ensure that when the occlusion, the micro-motion between the implant and the alveolar bone does not affect the osseointegration of the implant, so it usually takes a month to start the gradual load after the operation. Tolerate 2.3 is almost a function of the bite ^ ... Borrowing the second two, although clinically can be implanted in the full jaw of the edentulous patient's mandible 4 = 6 implants implanted after the implant, then implanted on the implant The horizontal bar () 'continuously difficult to establish __ He Wei dispersion stress, • 6- M355092 installed on the whole denture' immediately load and restore the chewing function. . 牙牙牙, the patient itself must have quite high conditions _, , limited reading in the loss of * strict face mandibular repair, bone loss, ^ patients and upper jaw are not suitable for this type of missing teeth repair. And not implanted in 5. Η立' will continue to shrink because of non-functional stimuli. 3. Headache problems caused by the joints of the joints of the joints • Face,! Γ: The combination with the implant is formed by a combination of epithelial adherent implants ine and forming a biological closure, also known as eUff. This is the weak part of the implant's H) and is also the implant success _ key. m weaving the most 4 due to the implant, abutment, crown and other components segmented... The joint between the abutment and the crown has a gap (ie the edge = the surface formed by the squatting agent, and the connection between the implant and the abutment) In the micro-gap (mlcrogap), it is easy to adhere to the beginning of the failure of bacteria to invade the cuff 15. < In the case of alfalfa planting, US Patent No. 6,991,462, revealing the "one-bodyized abutment crown 4_" (IA^Integrated Ab_ent Cr 〇wns) system, as shown in the third figure b, does not stick the crown to the abutment outside the mouth, although the system is a problem caused by the gap between the crowns, but because the system and the implant are divided into two soils... 20, there are still micro-slit joints between the implant and the abutment. Q: The temporary denture must be removed when implanting and installing the impression, but it destroys the ® mouth. It is susceptible to bacterial infection, and there are also multiple operations. And the sleeves of β, and the problem of no immediate occlusion function. Several long and complicated hands 4. The alveolar bone absorption affects the aesthetic effect after repair M355092 The lip side of healthy teeth and the lingual alveolar bone are concave height Lower teeth between the teeth and the adjacent teeth (inte xima丨嶋) The trough is read as a convex ancient product, so the alveolar ridge top is undulating.

但是由於:a.牙槽脊頂缺乏自然牙的牙肋帶的拉鹿 力刺激,b.種植體頂部平面結構,e.骨整合時解功能 刺激,d.種植體和基台間的縫隙存在的細菌等因素,所造 成牙槽脊頂萎縮、吸收,會導致生物學寬度(BiQlGgie爾^) 根向後退、牙齦萎縮,使得種植體或基台暴露,影響修 後的美學效果。 根據臨床經驗,種植體頸部牙槽骨於修復時,一年平 均喪失1.0mm,這是種植體修復上令醫師及患者頭痛的問 題。 有一種波浪型頸部的植體設計,如美國專利第 6527554、6537069、6854972、7090494、7291013 號案件 15所揭露的,都將植體頸部設計成波浪型,但這些設計仍未 解決構件接合處縫隙所衍生之問題,也都同時存在多次手 術及冗長而繁複的手續,以及缺乏立即負載和立即咬合功 能等問題。 另外’有一種如美國專利第6981873號案例中所揭露 20的’將植體的頸部5設計成Curve形狀,以利牙齦不同組織 的緊费結合,可避免生物學寬度的退縮,如第三圖A所 示’但此設計卻忽略了前述牙槽脊頂呈波浪起伏狀的構 造’仍難避免#間牙槽脊頂Bone peak的吸收,另外也無法 避免構件接合處縫隙衍生的問題。最重要的是仍無法做到 -8- M355092 立即咬合功能。 5. 齒槽骨萎縮問題 缺牙修復後,未植入植體的牙槽區繼績無功能性萎 縮’對全口無牙之修復有相當不利的缺點。骨膜下種植修 5復也因只突出四支支柱,底部網狀金屬網所覆蓋的齒槽骨 表面積有限’未受力的齒槽骨也會面臨無功能性萎縮的問 題,導致假牙鬆動、脫落,而無法使用假牙的現象。 6. 骨質的條件限制問題 植牙像蓋房子之前先打地基,若地盤不夠紮實,房子 10的穩定性不夠。骨質流失致齒槽骨高度、寬度、骨密度不 夠的,都不適合種植缺牙修復,這是普遍存在於老年病串、 的嚴重問題。 ~ 針對上述六項問題,申請人設計一特殊結構的人工牙 體,解決上述人工植牙普遍存在的頭痛問題。 15 【新型内容】 本創作之主要目的在於提供一種一次完成且具立即功 能的植入式人工牙體。 為達成上述目的,本創作設計一特殊結構之人工牙 20體,其中人工牙體的構造,包含有一人工牙齒;一 該牙頸呈現中段較窄而上下段漸寬的束腰狀;—人4 床,該人工牙床底面完全貼附並跨坐於齒槽骨表面, 載人工牙齒承受之咬合力;一 田 刀,人工牙根,用於植入齒槽 月’獻工牙根、人工牙床、牙頸與人工牙齒是一體成裂 M355092 的結構。 【實施方式】 為了說明本創作之特徵及功效,以下茲舉九個實施例 5 配合圖式詳細說明如後。 第一圖A與第一圖B為前案技術圖。 第二圖A與第二圖B為前案技術圖。 第三圖A與第三圖B為前案技術圖。 第四圖A與第四圖B為第一實施例之45°角側面示意 10 圖。 第五圖A與第五圖B為第二實施例之45°角侧面示意 圖。 第六圖為第三實施例之正面示意圖。 第七圖A、第七圖B與第七圖C為第四實施例不同形 15態之示意圖。 第八圖A與第八圖B為第五實施例之正面與側面示意 圖。 第九圖A與第九圖B為第六實施例之正面與側面示意 圖。 20 第十圖為第七實施例之斷面示意圖。 第十一圖A與第十一圖B為第八實施例之示意圖。 第十二圖為第九實施例之示意圖。 第十三圖A與第十三圖B為試裝假牙之示意圖。 如第四圖A及第四圖B所示,為本創作人工牙體的第 -10- M355092 一實施例,包含有: 一人工牙根ίο,用於植入於齒槽骨’為了增如該人工 牙根10與齒槽骨骨整合的緊密性’該人工牙根的部份可以 設置成粗糙的表面或是有凹紋1〇1(如第四圖B、第五圖 5 B、第十圖b所示),或是在人工牙根上設置横向的穿孔 102等等不同的結構。 一人工牙床11 ’設於該人工牙根上10,人工牙床u 底面完全貼附,並跨坐於齒槽骨表面,讓齒槽骨表面結構 較堅實的皮質骨來承受咬合力。 10 一牙頸12,設於該人工牙床11上,該牙頸呈現中段窄 上下漸寬的束腰狀。 一人工牙齒13,設於該牙頸12上。 上述之人工牙根1〇、人工牙床11、牙頸12與人工牙 齒13是一體成型的結構。 15 本創作是利用人工牙床11底面完全貼附,並跨坐於齒 槽骨表面’讓齒槽骨表面結構較堅實的皮質骨來承受咬合 力’所以不需骨整合,人工牙體植入當天即具備立即咬合 功能。 5亥人工牙床11的結構設計,是本創作中在一次手術 2〇後,就具備立即咬合功能的關鍵性因數。 本創作係一體成型之構造,所以沒有一般缺牙修復 中,構件接合處縫隙所造成修復失敗的問題。而且,在植 2藉助相關技術,只需開一次刀,將一體成型之人工牙 植入’不需分段實施,—魏可完成缺牙修復。 -11- M355092 當該人工牙體被植人時,該人I牙床u底 貼 附,並跨坐於齒槽骨表面,負起承 - 來可以減少人工牙根丨〇在受力時 .、壬,如* 過大而造成植牙失敗。U喊生微動’避免微動間距 5 10 15 另外,人4床η安置料 牙槽脊頂吸收,也可做為牙槽脊骨 =口應力了避免 學寬度往根謂退,㈣於^生物 題。 τ很外路、影響美觀上的問 又,由於人工牙齒的咬合力會被平均的傳導分佈於齒 齒槽骨無魏性萎縮或骨f流失。錢於$力狀態,避免 而且,本創作中人工牙床u的厚度, 的^狀態作調整,塾高已萎縮的齒槽骨,批=二 槽骨條件限制的問題。 个賞男回 如第五圖Α與第五圖Β所示,為本 ,,在本實施例中主要結構與前一實施例相似,= 在於該人工牙齒與牙頸12之接合處設置有-人工牙齦14, 以使牙齦陳合更好,麵免輯藏汗納垢。 如第六圖本創作第三實施例所示,該物Η上也可以 設置若干的凹穴m,讓牙銀結締組_纖 面上,與牙頸12的部份有更好的結合,使細生物學= 效果更好,避免牙槽脊頂吸收,所造成的生物學寬度往根 方後退,以致於牙根外露影響美觀上的問題。 如第七圖A '第七圖B及第七圖c所示,為本創作之 -12- 20 M355092 第四實施例,在本實施例中主要社 不同之處在於該人工牙床u由不同° :苐—實施例相似, 肩部I5覆蓋於牙槽骨的皮質骨上\ ^的肩部15取代,該 構可讓結構較堅硬的皮質骨來承擔咬入用有,:一、該結 牙槽脊骨承受應力而不致萎縮,二、 一、该結構使 代結構,使生物學寬度不致於彳為牙槽脊骨的替 問題。 根方移動,造成美觀上的 如第八圖Α與第人圖Β所示,為本創作 ίο ,在本實施例中主要結構與第四實施例相似,不同“ ^於該牙頸12與肩部15呈波浪起伏狀,以符合原本健康 牙齒的牙槽脊頂的形態。可避免牙槽脊頂的高度退縮,所 造成的生物學寬度往根錢退,以致料根外露影響美觀 上的問題。 1 如第九圖Α與第九圖β所示,為本創作之第六實施 15例,在本實施例中主要結構與第一實施例相似,不同之處 在於該人工牙齒兩側的下方,鄰近該牙頸12處各凹設有一 潛槽131,用於容納牙齦,藉此可以讓牙齦被包覆於該潛 槽’避免齦溝内塞入食物滋生細菌。 如第十圖所示,為本創作之第七實施例,在本實施例 中主要結構與第一實施例相似,不同之處在於該人工牙床 11上設有若干的貫孔m,該等貫孔ill自該人工牙床11 的頂面貫穿至底面’藉由此等貫孔ill的設置,可以使齒槽 骨與人工牙床11更緊密的結合。 如第十一圖A與第十一圖B所示,為本創作之第八實 -13- M355092 施例,在本實施例中主要結構包含有人工牙根1〇、牙頸Η 以及人工牙嵩13 ’與前述實施例不同之處在於人工牙根1〇 的下方橫設-螺栓16,人工牙根1G承受的壓力,大部份由 該螺栓16兩端結構較堅硬的皮質骨來承擔,以達到人工 體植入後立即具備咬合功能的目的。 如第十二圖所示,為本創作之第九實施例,本創作 結構可以運用於單顆、局部或是全口缺牙的修復,且上 顎皆可適用,此為全口缺牙修復的實施例。 10 15 20 卜如第十三圖A及第十三圖B所示,為本創作的第十 細*例,本貫施例為第一實施例人工牙體的試裝假牙。 叙牙疋為了#更快速且正_的裝設人卫牙體而設計。 U賴裝假牙20包含:一上部結構2(Π,由一人工牙齒 ,碩26、一人工牙床23組成;上部結構設有一通孔 由4人工牙齒22的頂面貫穿至該人工牙床23的底 2工以及,一下部結構202,包括一人工牙根24,設在讀 =工牙床23底面’—柱部25,設在該人工牙根%的項 丄该柱部25的頂面與人卫牙齒22 _面形狀相符 弟十三圖Α所示。 該柱部25直徑與通孔21 一樣,可插入通孔21而使上 示兩部結構結合在一起成為試裝假牙,如第十三圖B所 可傲ί。卩結構用來測試與牙射表面之適合性,其通孔2!However, due to: a. the alveolar ridge top lacks the natural teeth, the rib band stimulates the deer force, b. the top plane structure of the implant, e. the symmetry stimulus during bone integration, d. the gap between the implant and the abutment Factors such as bacteria, caused by atrophy and absorption of the alveolar ridge top, will lead to biological width (BiQlGgie er ^) roots retreat, gingival atrophy, so that the implant or abutment exposed, affecting the aesthetic effect of the repair. According to clinical experience, when the implant neck alveolar bone is repaired, it loses 1.0 mm per year, which is a problem for implants and patients to have headaches. There is a wavy neck implant design, such as those disclosed in U.S. Patent Nos. 6,257,554, 6,537,069, 6, 854,972, 7,090,494, and 7,291,013, all of which have been designed to be wave-shaped, but these designs still have unresolved component engagement. The problems arising from the gaps also have multiple operations and lengthy and complicated procedures, as well as the lack of immediate load and immediate occlusion. In addition, there is a type of neck 5 of the implant body designed as a Curve shape, as disclosed in the case of US Pat. No. 6,981,873, to facilitate the combination of the different tissues of the gums, and to avoid the shrinkage of the biological width, such as the third. Figure A shows 'but this design ignores the undulating structure of the alveolar ridge top'. It is still difficult to avoid the absorption of the Bone peak of the alveolar ridge top, and the problem of the gap origination of the joint of the joint is not avoided. The most important thing is still not able to do -8- M355092 immediate bite function. 5. The problem of alveolar bone atrophy After the edentulous repair, the alveolar area without implants has a non-functional atrophy, which has quite disadvantages for the restoration of the whole mouth. Subperiosteal implant repair 5 also because only four pillars are highlighted, and the surface area of the alveolar bone covered by the bottom mesh metal mesh is limited. The unstressed alveolar bone will also face the problem of non-functional atrophy, causing the denture to loosen and fall off. The phenomenon that dentures cannot be used. 6. Conditional limitations of bones The implants are grounded before the house is built. If the site is not solid enough, the stability of the house 10 is not enough. Bone loss caused by insufficient height, width and bone density of the alveolar bone is not suitable for implanted edentulous restoration. This is a serious problem that is common in senile disease. ~ For the above six questions, the applicant designed a special structure of the artificial tooth to solve the headache problem that is common in the artificial implant. 15 [New Content] The main purpose of this creation is to provide an implantable artificial tooth that is completed at one time and has immediate function. In order to achieve the above purpose, the present invention designs a special structure of the artificial tooth 20 body, wherein the artificial tooth structure comprises an artificial tooth; and the tooth neck has a narrow waist and a wide waist and a waist section; The bed, the bottom surface of the artificial gum bed is completely attached and sits on the surface of the alveolar bone, and the bite force of the artificial tooth is carried; the field knife, the artificial root, is used for implanting the alveolar month, the root of the work, the artificial gum, the neck The structure of the M355092 is integrated with the artificial teeth.

As shown in FIG. 4A and FIG. 4B, an embodiment of the present invention is the -10-M355092, which comprises: an artificial root ίο for implantation in the alveolar bone 'in order to increase the number The tightness of the artificial root 10 to the alveolar bone 'the part of the artificial root can be set to a rough surface or have a concave 1〇1 (such as the fourth figure B, the fifth figure 5 B, the tenth figure b Shown), or a different structure such as a lateral perforation 102 on the artificial root. An artificial tooth bed 11 ′ is disposed on the artificial root 10 , and the artificial gum bed u is completely attached to the bottom surface, and sits on the surface of the alveolar bone, so that the surface of the alveolar bone has a firmer cortical bone to bear the bite force. A tooth neck 12 is disposed on the artificial tooth bed 11 and has a waist-shaped shape in which the middle section is narrow and the upper and lower sides are gradually widened. An artificial tooth 13 is provided on the neck 12. The artificial root 1〇, the artificial gum 11, the neck 12 and the artificial tooth 13 are integrally formed. 15 This creation uses the artificial gum 11 to completely attach the bottom surface and straddle the surface of the alveolar bone to allow the cortical bone with a firmer surface structure to withstand the bite force. Therefore, no osseointegration is required, and the artificial tooth is implanted on the same day. That is, it has an immediate bite function. The structural design of the 5H artificial dental bed 11 is a key factor in the creation of the immediate occlusion function after 2 operations in this creation. This creation is a one-piece construction, so there is no problem of repair failure caused by gaps in the joints of the joints. Moreover, in the plant 2, with the help of related technology, it is only necessary to open the knife once, and the integrally formed artificial tooth is implanted 'without the need for segmentation, and Wei can complete the missing tooth restoration. -11- M355092 When the artificial tooth is implanted, the person's I-toe is attached to the bottom of the alveolar bone and sits on the surface of the alveolar bone. The load-bearing can reduce the artificial roots when the force is applied. If the * is too large, the implant will fail. U shouting micro-motion 'avoid fretting spacing 5 10 15 In addition, the human 4 bed η placement material alveolar ridge top absorption, can also be used as alveolar spine = mouth stress to avoid learning width to the roots retreat, (four) in ^ biological questions . τ is very external, affecting the aesthetics. Also, because the bite force of artificial teeth is distributed by the average conduction in the alveolar bone, there is no Wei atrophy or bone loss. The money is in the state of force, avoiding, and the thickness of the artificial gums u in this creation is adjusted, the height of the atrophic alveolar bone is reduced, and the batch = two-slot condition is limited. As shown in the fifth figure and the fifth figure, the main structure is similar to the previous embodiment in the present embodiment, and = the joint between the artificial tooth and the neck 12 is provided - Artificial gums 14 to make the gums better, and the face is free of sweat. As shown in the third embodiment of the sixth embodiment of the present invention, a plurality of recesses m may be disposed on the object, so that the silvery connective group _ the fiber surface has a better combination with the portion of the tooth neck 12, so that Fine biology = better effect, avoiding the absorption of the alveolar ridge top, and the resulting biological width retreats to the roots, so that the root exposure affects the aesthetic problems. As shown in the seventh figure A 'the seventh figure B and the seventh figure c, the fourth embodiment of the creation -12-20 M355092, in the present embodiment, the main difference is that the artificial gums u are different. : 苐 - similar to the embodiment, the shoulder I5 is covered by the shoulder 15 of the cortical bone of the alveolar bone. This structure allows the hard cortical bone to bear the bite. First, the gingival groove The spine is subjected to stress without atrophy. Second, the structure of the structure is such that the biological width does not become a substitute for the alveolar spine. The root side moves, resulting in an aesthetic appearance as shown in the eighth figure and the first figure. For the present creation, the main structure in this embodiment is similar to that of the fourth embodiment, and different "^ on the neck 12 and the shoulder The part 15 is undulating in shape to conform to the shape of the alveolar ridge of the original healthy tooth. The height of the alveolar ridge can be prevented from retreating, and the biological width caused by the roots is retreated, so that the root exposure affects the aesthetic problem. 1 as shown in the ninth diagram and the ninth diagram β, which is the sixth embodiment of the present invention. In the present embodiment, the main structure is similar to that of the first embodiment, except that the sides of the artificial teeth are below. Adjacent to the neck 12 is a recessed slot 131 for receiving the gums, so that the gums can be covered in the groove to prevent the food from breeding bacteria in the sulcus. As shown in the tenth figure, In the seventh embodiment of the present invention, the main structure is similar to the first embodiment in the present embodiment, except that the artificial gum 11 is provided with a plurality of through holes m, and the through holes ill are from the artificial dental bed 11 The top surface penetrates to the bottom surface , the alveolar bone can be more tightly combined with the artificial gum 11 .
