植體移除裝置 Implant removal device 【相關申請案】[related application]

本申請案主張2013年10月21日在韓國智慧財產局申請之韓國專利申請案第10-2013-0125553，其內容已藉參考方式完全併入本文中。 The present application claims the Korean Patent Application No. 10-2013-0125553, filed on Jan. 21, 2013, the disclosure of which is hereby incorporated by reference.

本發明係有關於一種植體移除裝置之一至多個實施例，特別是關於一種植體移除裝置用以移除***於齒槽骨形成人工齒根的植體。 The present invention relates to one to more embodiments of an implant removal device, and more particularly to an implant removal device for removing an implant inserted into the alveolar bone to form an artificial tooth root.

一般而言，植牙程序依據牙醫步驟，其中由適耐度材料如鈦所製成的人工齒根***且種植牙與失去牙齒的齒槽骨結合，接著牙齒修補物固定於人工齒根以回復缺齒之原始功能。 In general, the implant procedure is based on a dental procedure in which an artificial tooth root made of a suitable material such as titanium is inserted and the implant is combined with the alveolar bone that has lost the tooth, and then the dental prosthesis is fixed to the artificial tooth root to recover The original function of missing teeth.

牙齒植入組合過程包含：植體***於齒槽骨及形成人造齒根、螺絲鎖附臨接於植體及修補物的應用，將人工牙齒臨接於植體上。 The dental implant assembly process includes the application of the implant to the alveolar bone and the formation of the artificial tooth root, the screw lock attached to the implant and the prosthesis, and the artificial tooth is attached to the implant.

為了將植體***至齒槽骨，設有前置直徑的洞形成於齒槽骨內且植體具有公螺絲於植體外周邊表面，受旋轉以***洞內，然後植體***洞內且螺絲緊密鎖附於齒槽骨。 In order to insert the implant into the alveolar bone, a hole having a front diameter is formed in the alveolar bone and the implant has a male screw on the peripheral surface of the plant body, is rotated to be inserted into the hole, and then the implant is inserted into the hole and the screw Tightly attached to the alveolar bone.

有時植體***齒槽骨後由於不同原因必須移除， 如種植牙失敗或骨頭重生及由於植體週遭發炎導致失去牙骨。 Sometimes the implant must be removed after insertion into the alveolar bone for different reasons. Such as dental implant failure or bone regeneration and loss of dental bone due to inflammation around the implant.

在此情況下，如第1圖所示，在以一環鑽30切去植體10附近的人工齒骨20後，一牙科治療經常執行移除植體10過程。切去鄰近人工齒骨20原因是藉由一般螺絲移除工具單獨將植體10旋轉及抽出並不容易，因為植體10已經臨接於人工齒骨20。 In this case, as shown in Fig. 1, after the artificial tooth bone 20 near the implant 10 is cut with a burrow 30, a dental treatment often performs the process of removing the implant 10. The reason for cutting the adjacent artificial tooth bone 20 is that it is not easy to rotate and extract the implant 10 alone by a general screw removing tool because the implant 10 is already adjacent to the artificial tooth bone 20.

然而，使用環鑽30之程序造成植體附近大量的齒骨損耗，因而在移除先前植體後，剩餘齒骨已不足支撐新植體。同時由於剩餘齒骨於植體附近的厚度必須大於2mm以上且骨頭在移除植體後發生損失，因而需要額外的植骨。於此，額外的時間與成本於植牙過程中會增加。 However, the procedure for using the trephine 30 results in a large amount of dentate loss near the implant, so that after removal of the previous implant, the remaining dentate is insufficient to support the new implant. At the same time, because the thickness of the remaining tooth bone in the vicinity of the implant must be greater than 2 mm and the bone is lost after the implant is removed, additional bone grafting is required. Here, the extra time and cost will increase during the implant process.

有鑑於此，本發明之一至多個實施例，包括一植體移除裝置用於易於移除***並臨接於齒骨的植體，並減少鄰近齒骨的損失。 In view of this, one to many embodiments of the present invention include an implant removal device for easily removing implants that are inserted and adjacent to the dentate and reducing loss of adjacent dentition.

參考第2至5圖，依據本發明之一實施例中，一 植體移除裝置100，用於移除植體10因為下述原因如種植牙失敗或骨頭重生及由於植體附近發炎導致失去牙骨。 Referring to Figures 2 through 5, in accordance with an embodiment of the present invention, The implant removal device 100 is used to remove the implant 10 for reasons such as dental implant failure or bone regeneration and loss of the dental bone due to inflammation near the implant.

植體10在***且鄰接齒槽骨後形成一人工齒根且具有公頭螺絲12，螺絲鎖附至齒槽骨於植體10的外周緣面上。一耦接洞14由植體10上表面下以一預定深度形成於植體10內且在內周緣面的耦接洞14，母頭螺絲16設置以螺絲鎖附鄰接。修補物的應用如人工牙齒藉由鄰接固定於植體10。一般而言，植體10的公頭螺絲12形成為右手螺絲且母頭螺絲16也形成為右手螺絲。 The implant 10 forms an artificial tooth root after insertion and abutment of the alveolar bone and has a male screw 12 attached to the alveolar bone on the outer peripheral surface of the implant 10. A coupling hole 14 is formed in the implant 10 at a predetermined depth from the upper surface of the implant 10 and has a coupling hole 14 on the inner peripheral surface. The female screw 16 is disposed to be screwed to abut. The application of the prosthesis, such as an artificial tooth, is fixed to the implant 10 by abutment. In general, the male screw 12 of the implant 10 is formed as a right hand screw and the female screw 16 is also formed as a right hand screw.

植體移除裝置100，可以包括：一連接螺絲110，連接植體10之一母頭螺絲16及一移除起子120，接觸植體10上表面且當連接連接螺絲110時，藉由旋轉以移除植體10。 The implant removing device 100 may include: a connecting screw 110, a female screw 16 connected to the implant 10 and a removing driver 120, contacting the upper surface of the implant 10 and rotating when the connecting screw 110 is connected The implant 10 is removed.

在連接螺絲110外周緣面的一端，一連接公頭螺絲112，用於鎖附連接植體10之母頭螺絲16形成且一移除母頭螺絲114以一預定深度距離連接螺絲110的上部形成於連接螺絲110的另一端內。連接公頭螺絲112形成為右手螺絲相同於植體10的母頭螺絲16，然而移除母頭螺絲114形成為左手螺絲，螺紋線相反於連接公頭螺絲112。 At one end of the outer peripheral surface of the connecting screw 110, a male screw 112 is attached, and a female screw 16 for attaching the implant 10 is formed, and a female screw 114 is removed to form an upper portion of the connecting screw 110 at a predetermined depth. In the other end of the connecting screw 110. The connecting male screw 112 is formed as a female screw 16 having the right hand screw identical to the implant 10, however the female screw 114 is removed as a left hand screw, and the thread is opposite to the male screw 112.

同時，在連接螺絲110外周緣面的另一端，一第一工具耦接部118為多邊形，耦接一工具如扳手以旋轉連接螺絲110。第一工具耦接部118用於連接接螺絲110的連接公頭螺絲112至植體10的母頭螺絲16。 At the same time, at the other end of the outer peripheral surface of the connecting screw 110, a first tool coupling portion 118 is polygonal, and a tool such as a wrench is coupled to rotate the connecting screw 110. The first tool coupling portion 118 is configured to connect the male screw 112 of the screw 110 to the female screw 16 of the implant 10.

移除起子120的一端為圓柱形且內具有一***洞122且連接螺絲110另一端******洞122。一移除公頭螺絲 124連接連接螺絲110之移除母頭螺絲114設置於移除起子120的***洞122中心且以平行***洞122的方向延伸。移除公頭螺絲124形成為左手螺絲與移除母頭螺絲114相同。 One end of the removal driver 120 is cylindrical and has an insertion hole 122 therein and the other end of the connection screw 110 is inserted into the insertion hole 122. Remove the male screw The removal female screw 114 of the connection connecting screw 110 is disposed at the center of the insertion hole 122 of the removal driver 120 and extends in the direction of the parallel insertion hole 122. The removal of the male screw 124 is formed as the left hand screw is the same as the removal of the female screw 114.

藉由形成連接螺絲110的移除母頭螺絲114且移除起子120的移除公頭螺絲124為左手螺絲，移除公頭螺絲124連接移除母頭螺絲114；當移除起子120反時鐘方向旋轉亦即左手方向然後移除起子120往下移動至植體10並接觸植體10上表面以將植體10由齒槽骨移除。細部解釋如後所述。 By removing the female screw 114 of the connecting screw 110 and removing the removing male screw 124 of the driver 120 as a left-hand screw, the male screw 124 is removed to remove the female screw 114; when the screwdriver 120 is removed, the counterclock is removed. The directional rotation, i.e., the left hand direction, then removes the driver 120 and moves down to the implant 10 and contacts the upper surface of the implant 10 to remove the implant 10 from the alveolar bone. The detailed explanation will be described later.

同時，在移除起子120外周緣表面的另一端，一第二工具耦接部128為多邊形，耦接一工具如扳手以旋轉移除起子120。第二工具耦接部128用於連接移除起子120的移除公頭螺絲124至連接螺絲110的移除母頭螺絲114且移除植體10。 At the same time, at the other end of the outer peripheral surface of the driver 120, a second tool coupling portion 128 is polygonal, and a tool such as a wrench is coupled to rotate to remove the driver 120. The second tool coupling portion 128 is for connecting the removal male screw 124 of the removal driver 120 to the removal female screw 114 of the connection screw 110 and removing the implant 10.

同時，移除起子120底部一端接觸植體10上表面且一摩擦部126形成於移除起子120底部以增加移除起子120底部與植體10上表面的摩擦力。如第5圖所示，摩擦部126包含複數個鋸齒狀螺紋127形成於移除起子120的***洞122周緣，但不限制於此。例如，摩擦力可增加藉由讓摩擦部126表面粗糙或藉由塗佈高硬度粉末材料至摩擦部126表面。 At the same time, the bottom end of the removal driver 120 contacts the upper surface of the implant 10 and a friction portion 126 is formed on the bottom of the removal driver 120 to increase the friction between the bottom of the removal driver 120 and the upper surface of the implant 10. As shown in FIG. 5, the friction portion 126 includes a plurality of zigzag threads 127 formed on the periphery of the insertion hole 122 of the removal driver 120, but is not limited thereto. For example, the frictional force may be increased by roughening the surface of the friction portion 126 or by coating a high hardness powder material to the surface of the friction portion 126.

如第5圖所示，每一鋸齒狀螺紋可具有垂直前端127a及傾斜後端127b。此複數個鋸齒狀螺紋127形成如前所述，當反時鐘旋轉時，鎖附植體10上表面，因此可以當移除起子120接收到植體10時，可靠地傳遞反時鐘扭力。 As shown in Fig. 5, each serrated thread may have a vertical front end 127a and an inclined rear end 127b. The plurality of serrated threads 127 are formed as previously described, and when rotated counterclockwise, the upper surface of the implant 10 is attached, so that the counterclockwise torque can be reliably transmitted when the removal driver 120 receives the implant 10.

第6圖係分別表示本發明第2圖中移除起子拆成 兩部件之示意圖。 Figure 6 is a view showing the removal of the screwdriver in Figure 2 of the present invention, respectively. A schematic representation of two parts.

參考第6圖，移除起子120可包括兩部件120a,120b，彼此耦接或分離。藉由移除起子120包括兩部件120a,120b，具有移除公頭螺絲124在***洞122內部之移除起子120，可較容易製造。 Referring to Figure 6, the removal of the driver 120 can include two components 120a, 120b coupled or separated from one another. By removing the driver 120 comprising two parts 120a, 120b, the removal of the driver 120 with the removal of the male screw 124 inside the insertion hole 122 can be easier to manufacture.

兩部件120a,120b的第一部件120a具有***洞122於其內，供連接螺絲110另一端***第一部件120a且複數個鋸齒狀螺紋127形成摩擦部126於第一部件120a的底面。同時，兩部件120a,120b的第二部件120b具有移除公頭螺絲124******洞122內且第二工具耦接部128形成於移除公頭螺絲124上部。 The first member 120a of the two members 120a, 120b has an insertion hole 122 therein, and the other end of the connection screw 110 is inserted into the first member 120a and a plurality of zigzag threads 127 form a friction portion 126 on the bottom surface of the first member 120a. At the same time, the second member 120b of the two members 120a, 120b has the removal male screw 124 inserted into the insertion hole 122 and the second tool coupling portion 128 formed on the upper portion of the removal male screw 124.

同時，第二部件120b具有一第一耦接部133相較於移除公頭螺絲124有較寬直徑且介於移除公頭螺絲124與第二工具耦接部128間，而且第一部件120a具有一第一耦接洞131，以讓第二部件120b之第一耦接部133***並耦接於***洞122上部。第一耦接洞131及第一耦接部133為多邊形對應彼此形狀設置，藉此情況當第一耦接部133***第一耦接洞131時不空轉。 At the same time, the second component 120b has a first coupling portion 133 having a wider diameter than the removal male screw 124 and between the removal male screw 124 and the second tool coupling portion 128, and the first component The 120a has a first coupling hole 131 for inserting and coupling the first coupling portion 133 of the second component 120b to the upper portion of the insertion hole 122. The first coupling hole 131 and the first coupling portion 133 are disposed in a polygonal shape corresponding to each other, whereby the first coupling portion 133 is not idling when inserted into the first coupling hole 131.

同時，第一部件120a具有一第二耦接洞132直徑小於第一耦接洞131及***洞122，位於第一耦接洞131及***洞122間且第二部件120b具有一第二耦接部134***於第二耦接洞132，位於第一耦接部133與移除公頭螺絲124間，且第二耦接洞132及第二耦接部134為圓形並具有相互對應直徑。 At the same time, the first component 120a has a second coupling hole 132 having a smaller diameter than the first coupling hole 131 and the insertion hole 122, and is located between the first coupling hole 131 and the insertion hole 122 and the second component 120b has a second coupling. The portion 134 is inserted between the first coupling portion 133 and the removal male screw 124, and the second coupling hole 132 and the second coupling portion 134 are circular and have mutually corresponding diameters.

當第二部件120b的公頭螺絲124通過在第一部件120a裡面形成之第一耦接洞131及第二耦接洞132後，第二部件120b的移除公頭螺絲124******洞122定位時，第二部件120b的第一耦接部133和第二耦接部134分別***第一部件120a的第一耦接洞131及第二耦接洞132，因此第一部件120a和第二部件120b耦接彼此以形成移除起子120。 After the male screw 124 of the second component 120b passes through the first coupling hole 131 and the second coupling hole 132 formed in the first component 120a, the removal male screw 124 of the second component 120b is inserted into the insertion hole 122. The first coupling portion 133 and the second coupling portion 134 of the second component 120b are respectively inserted into the first coupling hole 131 and the second coupling hole 132 of the first component 120a, thus the first component 120a and the second component 120b are coupled to each other to form a removal driver 120.

應用本發明實施例植體移除裝置100來移除***人工齒骨的植體10之原則將細部描述並參考第3圖如下。 The principle of applying the implant removing device 100 of the embodiment of the present invention to remove the implant 10 into which the artificial tooth is inserted will be described in detail and referred to in Fig. 3 as follows.

首先，連接螺絲110耦接植體10，如第3圖所示。細部地，當工具如扳手耦接連接螺絲110之第一工具耦接部118且連接螺絲110旋轉順時鐘方向，連接螺絲110之連接公投螺絲112耦接植體10的母頭螺絲16，因此連接螺絲110耦接植體10。 First, the attachment screw 110 is coupled to the implant 10 as shown in FIG. In a detailed manner, when a tool such as a wrench is coupled to the first tool coupling portion 118 of the connecting screw 110 and the connecting screw 110 rotates clockwise, the connecting male screw 112 of the connecting screw 110 is coupled to the female screw 16 of the implant 10, thus connecting The screw 110 is coupled to the implant 10.

其次，移除起子120耦接連接螺絲110。細部地，當連接螺絲110的另一端***移除起子120的***洞122且一工具如扳手耦接移除起子120的第二工具耦接部128，然後移除起子120反時鐘旋轉，移除起子120的移除公頭螺絲124連接至連接螺絲110的移除母頭螺絲114且往下移動至植體10。 Next, the removal driver 120 is coupled to the connection screw 110. In detail, when the other end of the connecting screw 110 is inserted into the insertion hole 122 of the removal driver 120 and a tool such as a wrench is coupled to remove the second tool coupling portion 128 of the driver 120, then the driver 120 is removed for counterclockwise rotation, and removed. The removal male screw 124 of the driver 120 is coupled to the removal female screw 114 of the attachment screw 110 and moved down to the implant 10.

當移除起子120往下移動至植體10時，移除起子120底部接觸植體10上表面。在這因為連接螺絲110接受到張力且一壓力形成於移除起子120與植體10間，摩擦部126形成於移除起子120底部，亦即複數個鋸齒狀螺紋127緊密接觸植體10上表面並具有強的摩擦力。 When the removal driver 120 is moved down to the implant 10, the bottom of the removal driver 120 contacts the upper surface of the implant 10. Here, since the connecting screw 110 receives the tension and a pressure is formed between the removing driver 120 and the implant 10, the friction portion 126 is formed at the bottom of the removing driver 120, that is, the plurality of serrated threads 127 are in close contact with the upper surface of the implant 10. And has a strong friction.

依據本發明實施例，如上所解釋，植體移除裝置 100可有效應用強大順時鐘方向扭力於植體10***人工齒骨且因而單獨由齒槽骨移除植體10。藉由當移除植體10及***新植體同於先前植體直徑至相同位置且植體10附近骨頭損耗最少下，因為骨頭損失而造成的額外骨頭橋接則不需要，因此重新植入的時間與成本得以減少。 Implant removal device as explained above, in accordance with an embodiment of the present invention The 100 can effectively apply a strong clockwise torsion force to the implant 10 to insert the artificial tooth bone and thus remove the implant 10 from the alveolar bone alone. By removing the implant 10 and inserting the new implant to the same position as the previous implant diameter and with minimal bone loss near the implant 10, additional bone bridging due to bone loss is not required, so reimplantation Time and cost are reduced.
