201242577 六、發明說明： 〔發明所屬之技術領域〕 本發明係有關一種可促進骨整合之人工植牙體結 構’特別是指一種使用於微創式快速植牙系統之可促進骨 整合之人工植牙體結構。 〔先前技術〕 按’ 一般植牙手術’係藉由在患者預定裝設假牙的槽 骨裝設一人工植牙體（或稱人工牙根），然後藉由該人工 牙根將一贗復齒定位在口腔預定裝設假牙的牙齦位置上。 植牙的過程約略可分成二個階段《第一階段先在齒槽 骨鑽孔，並將一人工植牙體鎖入槽骨的孔中，當植牙體鎖 入的初期，槽骨的組織尚未與植牙體發生骨整合 (Osseointegration)，因此需經過一段避免受力期 (stress — free period)，此時應盡量避免微小移動 (micro — mot i on)導致人工植牙體表面上之新生骨組織產 生鬆動，故人工植牙體植入後，通常會先將牙肉暫時縫 合。待骨整合期過後，新生骨組織與人工植牙體已呈緊密 結合狀態，再進行第二階段，重新打開牙肉並將一支檯體 (abutment)固定在人工植牙體上。最後，再將廣復齒製作 於支檯體上。 由於鈦金屬具有高度生物相容性，人體不易產生排斥 或發炎，且骨組織容易於鈦金屬表面上生長並直接與鈦金 屬結合，因此被廣泛地使用於製作人工植牙體。藉此，人 工植牙體與齒槽骨間的結合，不純粹倚賴機械力，亦利用 201242577 生物表面接合力，來達到更佳之結合效果。 習用的人工植牙體係概呈圓柱狀，其外表面設有一螺 牙部，係可鎖入前述患者之槽骨中，於該植牙體頂端的中 央具有一個安裝孔’可供前述的支檯體的一部分插入於該 安裝孔中，藉以使該支檯體與人工植牙體相互結合在一 起。 為了促進該人工植牙體與患者槽骨的骨整合，並避免 植牙體植入初期的微小位移，因此會在植牙體的外型結 構、表面處理方式進行各種的改良。 一般人工植牙體，植入到槽骨之後，植牙體的本體大 部分都會埋入到槽骨内層的海綿骨組織中，而只有頂端與 支檯座連接的頸部的外側表面約有2mm左右的部分會與 槽骨外層的皮質骨組織接觸，由於皮質骨組織的硬度與強 度均高於海綿骨組織，因此植入體的頸部與皮質骨是否能 夠穩固地結合’成為植入體是否獲得足夠支撐的關鍵因 素。 因此’在習用的人工植入體的構造上，往往可以看到 在植入體的頸部外侧表面設置細螺紋，以增加頸部表面與 皮質骨組織咬合力的目的；例如，中華民國專利第丨557丄 號案’ M344871號案’以及美國專利申請第11/074051號 案。 然而’習用的人工植牙體所採用的在頸部設置細螺紋 的構造，僅能夠達到增加植牙體與皮質骨抓附力的目的， 對於促進骨質生長縮短骨整合時間並沒有顯著的幫助，因 此在植牙體植入後，仍然必須等待相當長的時間，槽骨才 201242577 能與植牙體完全地骨整合，因此㈣無法有效降低植牙手 術的失敗率。 、發明人有鑑於上述因素，乃苦思細索，積極研究，加 以多年從事相關產品研發之經驗，並經不斷試驗及改良， 終於發展出本發明。 〔發明内容〕 本發明主要目的，在提供一種可以提高植牙體與槽骨 結合穩定性，同時又可促進槽骨的皮質骨成長，使皮質骨 與植牙體的頸部的骨整合更為完整的可促進骨整合之人 工植牙體結構。 本發明主要技術内容，係為在植牙體的頸部與槽骨的 皮質骨組織接觸部位的外側表面，以機械加工方法設置有 Μ花紋路’使得該頸部與皮質骨咬合的力量更為穩固，同 時可以藉由該壓花紋路所形成的間隙提供保留骨血的空 間’因此有助於皮質骨組織的成長，而縮短骨整合時間， 並提高骨整合的完整性。 本發明為達成上述及其他目的，所採用之技術手段、 元件及其功效，茲採一較佳實施例配合相關圖式詳細說明 如下。 〔實施方式〕 圖1至圖3所示係為本發明的第一實施例’本發明之 可促進骨整合之人工植牙體結構，其中該植牙體10係為 一利用金屬材料一體成形製成之圓枉體，依照該植牙體植 201242577 部位㈣㈣方向’可定義出―上端部分及一 下端部分’該植牙體10的下端部分係概呈圓柱狀，且其 外表設置有一螺牙部11，而其頂端具有-個頸部12，_ =12之上方可進—步連接—支檯座2q，並藉由該域 座20將-個職齒3G安裝於該植牙體1()的上 3所示）。 _ 如圖2所示’該植牙體1〇的螺牙部u係為一自攻螺 牙，該螺牙部11前端的侧面可設置至少一溝槽13，使該 螺牙11在鎖入到患者口腔的槽骨時，能夠更容易地咬 入槽骨的組織中，並容納該螺牙部u切削槽骨所產生的 骨屑。此外該螺牙部1 i的外表面可以採用喷砂、化學腐 钮、或電聚處理等表面加工，使其表面呈現粗經狀態，以 提高該螺牙部11的親血性，以及槽骨與該植牙體1〇骨整 合後的密合性。 如圖3所示，本發明第一實施例的植牙體1〇係採多 段式植牙體的設計，亦即該植牙體1〇與前述用以安裝贗 復齒30的支檯座20係為分離個體的構造。如圖3所示， 本發明的植牙體在進行植牙手術時，係先以鑽孔器械於患 者口腔的槽骨40預定裝設假牙的位置預先鑽孔，然後再 將該植牙體10鎖入到該槽骨4〇的孔中。 當植牙體10植入到槽骨40以後，該植牙體10下端 的螺牙部11係鎖入於該槽骨40的組織之令，而植牙體 10頂端的頸部12係位於可與該槽骨40外層的皮質骨組 織41相互接觸的位置。依據一般植牙的手術程序，該植 牙體10植入到槽骨40以後，會先將牙齦部分縫合，待槽 201242577 骨40與植牙體10發生骨整合後，再重新開刀使植牙體 10的頂端露出牙齦外，然後再將前述支檯座20裝置到植 牙體10的頸部12的上端，然後再將前述贗復齒30成型， 並裝設在該支檯座20上。 本發明主要特徵，係在於該人工植牙體10的頸部12 的表面係經由輥壓加工方式，形成具有由複數的凹入、或 凸出於該頸部12之側表面的花紋所組成的凹凸紋路14的 形狀’因此使該頸部12與槽骨4 0的皮質骨組織41的接 觸面積增加，且應力分佈狀態改變，而能夠增進皮質骨組 織41與頸部12的接合力量’並使頸部12與皮質骨組織 41接觸的應力能均勻地分佈。 該頸部12設置凹凸紋路14的作用，除了增加頸部 12與皮質骨組織41咬合的穩定性以外，更重要的是能夠 將更多的血液保留在頸部12與皮質骨組織4丨之間的空隙 中，而達到提高頸部12與皮質骨組織41之間骨血含量， 因此有助於植牙體1〇植入後，皮質骨組織41的生長速 度，而促進皮質骨組織41與頸部12的骨整合速度，並且 使骨整合更為密合。 本發明第-實施例的植牙體1G，係利用滾壓加工的 方式在頸部12的表面輥壓上前述的凹凸紋路14;而該凹 凸紋路14的紋路間距，係概略為〇.卜ο」丽#尺寸範圍 内。 然而在此必須強調，前述的凹凸紋路14的製作方 法’可採用滾壓、壓花犛朔} !化寺塑性變形的加工方式，也可以採 用切削方式製作，其並不限定於姓〜 不隈叱於特定的加工方式。同時’ 201242577 該凹凸紋路14的形狀以及花紋的間距、尺寸也沒有特定 限制’可依照實際需求加以改變。 圖4所示，係為本發明應用於一體式植牙體的實施 例。其中該一體式的植牙體1〇A之下端係為一螺牙部 11A ’該螺牙部前段部分的外側設有至少一溝槽13 a ;其 頂端具有一頸部12A且於該頸部12A的頂端一體成型地設 有一支檯座20A。同時’於頸部12A的外側表面，與第一 實施例相同地，設有一凹凸紋路14A，藉以促進該植牙體 10A植入到患者口腔槽骨後，槽骨的皮質骨組織與該頸部 12A的骨整合速度與完整性。 本發明上述技術手段’可有效地提升人工植牙體 10、10A植入到槽骨40初期的穩固性，並且有效促進槽 骨40的皮質骨組織41與植牙體之頸部12、12A的骨整合 速度與密合度，因此其倶已符合發明專利之新穎性及進步 性要件。惟說明書所揭示僅為針對本發明較佳之可行實施 例說明而已，該實施例並非用以限定本發明之申請專利範 圍，亦即其它未脫離本發明所揭示之技藝精神下所完成之 均等變化，均應包含於本發明之申請專利範圍中。 〔圖式簡單說明〕 圖1係為本發明第一實施例之人工植牙體的側面視圖。 圖2係為本發明第—實施例之人工植牙體的立體圖。 圖3係為本發明第—實施例之人工植牙體植人於患者口 腔植牙位置的槽骨中，並將復齒安裝於該植牙體之上 的狀態下的使用狀態示意圖。 201242577 圖4係為本發明第二實施例之人工植牙體的側面視圖 〔主要元件符號說明〕 10、 10A 植牙體 11、 11A 螺牙部 12、 12A 頸部 13、 13A 溝槽 14、 14A 凹凸紋路 20、20A 支檯座 30 贗復齒 40 槽骨 41 皮質骨組織201242577 VI. Description of the invention: [Technical field to which the invention pertains] The present invention relates to an artificial dental implant structure capable of promoting osseointegration, in particular to an artificial implant for promoting osseointegration for use in a minimally invasive rapid dental implant system Dental structure. [Prior Art] According to the 'general implant surgery', an artificial implant (or artificial root) is placed on the groove of the patient to be equipped with a denture, and then the artificial tooth is positioned by the artificial root. The oral cavity is intended to be placed on the gingival position of the denture. The process of implanting teeth can be roughly divided into two stages. The first stage first drills the alveolar bone and locks an artificial implant into the hole of the trough. When the implant is locked, the trough tissue Osseointegration has not yet occurred with the implant, so it is necessary to go through a period of stress-free period. In this case, micro-movement should be avoided as much as possible to cause new life on the surface of artificial implants. The bone tissue is loosened, so after the artificial implant is implanted, the meat is usually temporarily sutured. After the bone integration period, the new bone tissue and the artificial implant have been tightly combined, and then the second stage is performed, the tooth is reopened and an abutment is fixed on the artificial implant. Finally, the wide-toothed teeth are made on the abutment body. Titanium is widely used in the manufacture of artificial implants because of its high biocompatibility, the human body is less prone to repulsion or inflammation, and bone tissue is easily grown on the surface of titanium metal and directly bonded to titanium metal. In this way, the combination of the artificial implant and the alveolar bone does not rely solely on mechanical force, but also uses the 201242577 bio-surface joint force to achieve a better combination. The conventional artificial implant system has a cylindrical shape, and has a threaded portion on the outer surface thereof, which can be locked into the groove of the patient, and has a mounting hole in the center of the top of the implant body for the aforementioned abutment A part of the body is inserted into the mounting hole, so that the abutment body and the artificial implant body are coupled to each other. In order to promote the osseointegration of the artificial implant and the patient's trough, and to avoid the slight displacement in the initial stage of implantation of the implant, various improvements are made in the external structure and surface treatment of the implant. Generally, the artificial implant body is implanted into the trough bone, and most of the body of the implant body is buried in the sponge bone tissue in the inner layer of the trough, and only the outer surface of the neck connected to the support base is about 2 mm. The left and right parts will contact the cortical bone tissue of the outer layer of the trough. Since the hardness and strength of the cortical bone tissue are higher than that of the spongy bone tissue, can the neck and cortical bone of the implant be firmly combined to become the implant? The key factors to get enough support. Therefore, in the construction of conventional artificial implants, it is often seen that fine threads are placed on the outer surface of the neck of the implant to increase the bite force between the neck surface and the cortical bone tissue; for example, the Republic of China patent丨 557 案 case 'M344871' and US Patent Application No. 11/074051. However, the use of the finely threaded structure in the neck of the conventional artificial implants can only achieve the purpose of increasing the grasping force of the implant and the cortical bone, and does not significantly contribute to the promotion of bone growth and shortening the time of osseointegration. Therefore, after implantation of the implant, it still has to wait for a long time, and the trough bone can only fully integrate with the implant body 201242577, so (4) can not effectively reduce the failure rate of dental implant surgery. In view of the above factors, the inventors have developed their inventions through careful research, active research, and years of experience in research and development of related products, and through continuous testing and improvement. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for improving the stability of the joint between the implant and the trough, and at the same time, promoting the growth of the cortical bone of the trough, and integrating the cortical bone with the osseointegration of the neck of the implant. Complete artificial implant structure that promotes osseointegration. The main technical content of the present invention is that the outer surface of the contact portion between the neck of the implant body and the cortical bone tissue of the trough is mechanically processed to provide a sacral pattern to make the neck and the cortical bone more forceful. Stable, at the same time, the gap formed by the embossed road can provide a space for retaining bone blood', thus contributing to the growth of cortical bone tissue, shortening the time of osseointegration, and improving the integrity of osseointegration. The present invention has been made in view of the above-described and other objects, the technical means, the components and the effects thereof, and the preferred embodiment is described in detail below with reference to the related drawings. [Embodiment] Figs. 1 to 3 show a first embodiment of the present invention. The artificial dental implant structure of the present invention which promotes osseointegration, wherein the dental implant body 10 is integrally formed of a metal material. In the round body, according to the implant body 201242577 part (four) (four) direction ' can be defined - the upper end part and the lower end part 'the lower end part of the implant body 10 is generally cylindrical, and its outer surface is provided with a screw portion 11, and the top end has a neck 12, _ = 12 can be further connected to the support base 2q, and the field gear 3G is mounted on the implant 1 () The above 3 shows). _ As shown in FIG. 2, the thread portion u of the dental implant body is a self-tapping screw, and at least one groove 13 can be disposed on the side surface of the front end of the screw portion 11, so that the thread 11 is locked. When it reaches the trough of the patient's mouth, it can more easily bite into the tissue of the trough and accommodate the bone fragments generated by the threaded part u cutting the trough. In addition, the outer surface of the screw portion 1 i may be subjected to surface processing such as sand blasting, chemical corrosion button, or electropolymerization treatment, so that the surface thereof is roughened to improve the blood affinity of the screw portion 11 and the groove bone and The implant 1 has the adhesion after integration of the tibia. As shown in FIG. 3, the dental implant 1 according to the first embodiment of the present invention adopts a design of a multi-stage dental implant, that is, the dental implant 1 and the aforementioned support base 20 for mounting the complex tooth 30. It is the structure that separates the individual. As shown in FIG. 3, in the dental implant operation of the present invention, the dental implant body is pre-drilled at a position where the dental prosthesis 40 of the patient's mouth is scheduled to be installed with a drilling tool, and then the dental implant body 10 is Lock into the hole of the trough 4〇. After the implant body 10 is implanted into the trough 40, the threaded portion 11 at the lower end of the implant body 10 is locked into the tissue of the trough 40, and the neck 12 at the top of the implant 10 is located. A position in contact with the cortical bone tissue 41 of the outer layer of the trough 40. According to the surgical procedure of the general implant, after the implant 10 is implanted into the trough 40, the gingival part is first sutured, and after the osseointegration of the bone 40 and the implant 10 is performed in the groove 201242577, the implant is re-opened to make the implant The top end of the 10 is exposed to the gums, and then the abutment seat 20 is attached to the upper end of the neck portion 12 of the implant body 10, and then the aforementioned gingival teeth 30 are molded and mounted on the pedestal base 20. The main feature of the present invention is that the surface of the neck portion 12 of the artificial dental implant body 10 is formed by a roll processing method, and is formed by a pattern having a plurality of concave portions or protruding from the side surface of the neck portion 12.
