發明領域

發明背景
這種牙植入體從專利EP 1 418 858中已知。在已知的牙植入體中，套管膠黏在芯體上。為此目的，在套管的內壁和芯體的上部之間留有80-150µm的間隙。該間隙能夠形成足夠的空間，以使套管和芯體之間具有良好的彈性。
這種牙植入體從專利EP 1 418 858中已知。在已知的牙植入體中，套管膠黏在芯體上。為此目的，在套管的內壁和芯體的上部之間留有80-150µm的間隙。該間隙能夠形成足夠的空間，以使套管和芯體之間具有良好的彈性。
已知植入體的一個缺點是存在脫黏的風險。實際上，已經確定，當將這些植入體插入緻密或不規則的頜骨中時或將這些植入體插入緻密或不規則的頜骨中之後，頜骨有時會將套管往回推並因此導致黏合劑鬆動，從而導致套管從芯體上脫離。因此，這些植入體不適合完全置於頜骨中，並且套管不能與骨接觸。
發明概要
本發明的目的是實現一種牙植入體，其中脫黏和斷裂的風險得到明顯降低。
本發明的目的是實現一種牙植入體，其中脫黏和斷裂的風險得到明顯降低。
為此目的，根據本發明的植入體的特徵在於，所述間隙的距離在5µm至30µm之間，特別是在10µm至20µm之間。該間隙值能夠出乎意料地結合以下方面：一方面，插入時和與骨接觸時良好的阻力，另一方面在芯體和套管之間保持足夠的空間從而能夠在套管和芯體之間實現一定的彈性。該間隙值還使得可以在固定在芯體上的套管的拉力測試中獲得更好的結果，並降低在該測試中斷裂的可能性。然後，該套管可以部分地或整體地嵌入骨中，並且即使在頜骨不規則的情況下，該植入體也可以完全嵌入頜骨中。
根據本發明的牙植入體的第一優選實施方式的特徵在於，製造套管的陶瓷是氧化鋯。氧化鋯是一種具有優異的生物相容性的材料，特別是當與軟組織接觸時尤為如此。
根據本發明的牙植入體的第二優選實施方式的特徵在於，黏合劑層是生物相容性雙組分環氧黏合劑層。這種黏合劑非常適合牙植入體用途。
較佳實施例之詳細說明
現在將參考唯一的附圖1更詳細地描述本發明，該附圖1示出了根據本發明的牙植入體的實施方式。
現在將參考唯一的附圖1更詳細地描述本發明，該附圖1示出了根據本發明的牙植入體的實施方式。
該圖1示出了根據本發明的牙植入體1的橫截面。牙植入體包括由金屬，特別是鈦製成的芯體2。鈦具有耐用、柔韌和生物相容性的優點，可用作患者口腔中的牙植入體。芯體優選地具有外螺紋，使得能夠將芯體擰入頜骨中。
套管3放置在芯體的上部並且在芯體的整個圓周上延伸。套管具有內壁並且通過在芯體的上部上滑動而嵌套，使得當植入體植入患者的頜骨中時所述內壁面向芯的上部，所述套管位於骨和口腔之間的牙齦中。
套管優選地由陶瓷製成，更具體地由氧化鋯製成。 套管也可以由PEEK製成。
在芯體和套管內壁之間留有間隙4，使得黏合劑層可以容納在由該間隙的存在而形成的空間中。間隙的距離在5µm至30µm之間，特別是在10µm至20µm之間。該間隙在套管的整個高度上延伸，使得一方面通過套管在芯體的上部上的滑動來促進嵌套，另一方面使得黏合劑層能夠在該整個高度上延伸，從而使套管和芯體之間具有良好的黏附性和良好的組裝。
用於將套管黏附在芯體上的黏合劑優選是雙組分環氧黏合劑。這種黏合劑很好地被人們所接受用於口腔的牙植入體，因為其具有生物相容性。
留下距離在5µm到30µm之間，特別是在10µm到20µm之間的間隙的優點在於出乎意料地結合了以下方面：一方面，在與頜骨接觸時套管具有良好的阻力，另一方面，為了施加的咀嚼力，在芯體和套管之間保持足夠的空間，從而在套管和芯體之間能夠具有一定的彈性。實際上，現有技術中已知的牙植入體存在套管從芯體脫離的問題。對該問題的深入分析已經可以確定，當植入體被植入患者口腔時，頜骨有時將植入體的套管往回推。這是因為骨實際上從來不是完全平坦的，即使小於1毫米級別的骨脊中的一些小的不規則性也會導致對套管的壓力。因此，由頜骨施加在套管上的這種壓力可能導致在施加植入體時黏附和組裝的鬆動，從而導致套管離開芯體。
距離在5µm到30µm之間、特別在10µm到20µm之間的該間隙值還使得可以在固定在芯體上的套管的拉力測試中獲得更好的結果，並降低在該測試中斷裂的可能性。在製造植入體時在製造車間進行這些測試，以驗證固定在芯體的套管的抗拉性。這些測試能夠確定即使使用薄的黏合劑層，在套管和芯體之間也可獲得足夠的彈性，以避免套管破裂。
根據本發明的間隙的另一個優點是在該間隙留下的空間中細菌浸潤的風險最小化。實際上，關於該極小距離的間隙，由於間隙形成的空間中填滿了生物相容性黏合劑，所以似乎可以說沒有留給細菌的空間。
