Abstract
Description
本發明係有關一種植牙手術裝置及方法，更特別有關一種用於植牙手術之骨頭增高裝置及方法。 The invention relates to a dental implant surgery device and method, and more particularly to a bone height increasing device and method for dental implant surgery.
傳統處理缺牙的方法須將缺牙兩旁之牙齒磨小，作為固定牙橋的支柱以固定假牙，因此不但會破壞兩側健康牙齒的琺瑯質及結構，並且存在著術後清潔不易、及咀嚼力較差等缺點。近年來，人工植牙已逐漸地取代傳統缺牙治療方式，以解決前述缺失。人工植牙係在缺牙處，將一鈦金屬植體經由外科手術植入缺牙區之齒槽骨內作為人工牙根，於植體與齒槽骨緊密結合後，再於植體之基座上裝上牙冠。因植體部分深植於牙床骨內並與齒槽骨緊密結合，故牙冠不需再以牙橋與自然牙齒相連，即能承受正常之咀嚼力量，功能與美觀上幾乎媲美自然牙。 The traditional method of treating the missing teeth is to grind the teeth on both sides of the missing tooth as the pillar of the fixed bridge to fix the denture, so that it not only destroys the enamel and structure of the healthy teeth on both sides, but also has difficulty in postoperative cleaning and chewing. Poor and other shortcomings. In recent years, artificial implants have gradually replaced traditional edentulous treatments to address the aforementioned shortcomings. The artificial implant system is located in the missing tooth. A titanium metal implant is surgically implanted into the alveolar bone of the edentulous region as the artificial root. After the implant and the alveolar bone are tightly combined, the implant is placed on the base of the implant. Top on the crown. Because the implant part is deeply implanted in the bone of the gum and tightly combined with the alveolar bone, the crown does not need to be connected with the natural tooth by the bridge, which can withstand the normal chewing force, and the function and appearance are almost comparable to the natural tooth.
植牙手術係於患者預植牙處進行麻醉，把植牙處的牙齦皮瓣翻開，讓齒槽骨露出，利用植牙器械在齒槽骨上進行鑽孔，以形成骨窩洞，再將植體之人工牙根植入骨窩洞，讓人工牙根埋入骨窩洞，再與齒槽骨逐漸緊密結合。如圖1A所示，若齒槽骨10的條件不佳，即齒槽骨萎縮時，將導致植入的人工牙根20部份外露，無法與齒槽骨逐漸緊密結合，而易造成植體植入手術失敗。因此，需要進一步進行植骨手術，以增加植體植入手術成功率。 The implant surgery is performed on the patient's pre-planted teeth, the gingival flap of the implant is opened, the alveolar bone is exposed, and the dental implant is used to drill the alveolar bone to form a bone cavity. The artificial root of the implant is implanted into the bone cavity, and the artificial root is buried in the bone cavity, and then gradually combined with the alveolar bone. As shown in FIG. 1A, if the condition of the alveolar bone 10 is not good, that is, when the alveolar bone is atrophied, the artificial artificial root 20 of the implant will be partially exposed, and the implanted bone can not be gradually tightly combined, which is easy to cause implanting. The operation failed. Therefore, further bone grafting is needed to increase the success rate of implant implantation.
如圖1B所示，目前植骨手術係將一包覆膜30，如鈦金屬網或再生膜，包覆於預補骨的齒槽骨上，而於鈦金屬網或再生膜30與齒槽骨之間填充骨粉40。於補完骨粉40 後，再將牙齦皮瓣覆蓋在鈦金屬網或再生膜30上，並加以縫合，或以固定釘32將鈦金屬網或再生膜30固定於齒槽骨10上。倘若鈦金屬網或再生膜30未確實固定，容易受力擠壓造成變形或移位，甚至撐開牙齦皮瓣而露出，造成植骨結果不理想甚或失敗。然而，臨床上發現，因患者口腔內部作業空間狹小，及固定釘32極為精細，因而不易將牙齦皮瓣與鈦金屬網或再生膜30加以縫合，或確實以固定釘32將鈦金屬網或再生膜30固定於齒槽骨10上。再者，僅藉由鈦金屬網或再生膜30及骨粉40，其能提供之植骨高度有限。若患者齒槽骨10萎縮嚴重，則無法提供所需之植骨的高度。 As shown in FIG. 1B, the current bone grafting operation coats a coating film 30, such as a titanium metal mesh or a regenerated film, on the alveolar bone of the pre-bone, and the titanium metal mesh or the regenerated film 30 and the cogging. The bone powder 40 is filled between the bones. In the completion of bone powder 40 Thereafter, the gingival flap is overlaid on the titanium mesh or the regenerated film 30, and the titanium mesh or the regenerated film 30 is fixed to the alveolar bone 10 by the fixing nails 32. If the titanium metal mesh or the regenerated film 30 is not fixed, it is easily deformed or displaced by force extrusion, and even the gingival flap is opened to expose, resulting in unsatisfactory or even failure of the bone grafting result. However, it has been clinically found that because the working space inside the patient's mouth is narrow and the fixing nails 32 are extremely fine, it is difficult to suture the gingival flap with the titanium metal mesh or the regenerated film 30, or the titanium metal mesh or the reinforcing nail 32 is actually regenerated. The membrane 30 is fixed to the alveolar bone 10. Furthermore, the bone graft height that can be provided is limited only by the titanium metal mesh or the regenerated film 30 and the bone powder 40. If the patient's alveolar bone 10 is severely atrophied, the height of the desired bone graft cannot be provided.
有鑑於此，便有需要提出一種用於植牙手術之骨頭增高裝置及方法，以解決上述問題。 In view of this, there is a need to provide a bone augmentation device and method for implant surgery to solve the above problems.
本發明之目的在於提供一種用於植牙手術之骨頭增高裝置及方法，其除易於將鈦金屬網或再生膜固定於齒槽骨上，亦可提供各種所需之植骨的高度。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a bone augmentation apparatus and method for implant surgery which, in addition to facilitating the attachment of a titanium metal mesh or a regenerative membrane to the alveolar bone, can also provide a variety of desired bone graft heights.
為達上述目的，本發明之骨頭增高裝置主要包含一本體，一固定根部，及一固定座。該固定根部外徑具螺牙，自本體向下延伸，且於本體與固定根部交接處形成一階梯部。固定座可與一定位元件鎖合或扣合，以固定一鈦金屬網或再生膜之包覆膜。該固定根部具有一預定長度，通常約為2-4mm。於植骨手術時，因該固定根部具有一預定長度，且本體與固定根部交接處形成一階梯部，醫師於旋入固定根部至齒槽骨時，無須時常量測旋入固定根部之深度，而可一次旋入到位，直到階梯部抵住齒槽骨。本體可依需要，事先製作成不同高度。因此，醫師於行植骨手術時，可事先選擇所需支撐高度之骨頭增高裝置，用以支撐及固定包覆膜。本發明之用於植牙手術之骨頭增高裝置及方法，其除易於將鈦金屬網或再生膜固定於齒槽骨上，亦可提供各種所需之植骨的高度。 To achieve the above object, the bone heightening device of the present invention mainly comprises a body, a fixed root portion, and a fixing base. The fixed root outer diameter has a thread extending downward from the body and forming a step at the intersection of the body and the fixed root. The fixing seat can be locked or fastened with a positioning component to fix a coating film of a titanium metal mesh or a regenerated film. The fixed root has a predetermined length, typically about 2-4 mm. In the bone grafting operation, since the fixed root has a predetermined length and a step is formed at the intersection of the body and the fixed root, the physician does not need to measure the depth of the fixed root when the screw is fixed into the alveolar bone. Instead, the screw can be screwed into place until the step is against the alveolar bone. The body can be made into different heights in advance as needed. Therefore, when performing a bone graft operation, the physician can select a bone height increasing device of a required support height in advance to support and fix the coating film. The bone heightening device and method for implant surgery of the present invention can provide a variety of desired bone graft heights in addition to the ease of fixing the titanium metal mesh or the regeneration film to the alveolar bone.

參考第2及5A圖，本發明之骨頭增高裝置50主要包含一本體52，一固定根部54，及一固定座56。該固定根部54外徑具螺牙，自本體52向下延伸，且於本體52與固定根部54交接處形成一階梯部53。固定座56位於本體52上方，其可供一板手或專用工具驅動旋轉，而將具螺牙之固定根部54旋入齒槽骨10內，而將骨頭增高裝置50固定於齒槽骨10內。固定座56可與一定位元件60鎖合或扣合，以固定一鈦金屬網或再生膜之包覆膜30。該固定根部54具有一預定長度，通常約為2-4mm。於植骨手術時，因該固定根部54具有一預定長度，且本體52與固定根部54交接處形成一階梯部53，醫師以一板手或專用工具將骨頭增高裝置50之固定根部54旋入齒槽骨10內時，可將固定根部54一直旋入直到階梯部53頂住齒槽骨10。因此，醫師於旋入固定根部54至齒 槽骨10時，無須時常量測旋入固定根部54之深度，以判斷是否需再旋入固定根部54，而可一次旋入到位。此設計除可大幅減少手術時間外，亦可減少固定根部54旋入不足或太多而造成手術失敗之機會。 Referring to Figures 2 and 5A, the bone raising device 50 of the present invention mainly comprises a body 52, a fixed root portion 54, and a fixing seat 56. The fixed root portion 54 has a screw with an outer diameter extending downward from the body 52, and a step portion 53 is formed at the intersection of the body 52 and the fixed root portion 54. The fixing seat 56 is located above the body 52, and can be driven to rotate by a wrench or a special tool, and the fixed root 54 of the screw is screwed into the alveolar bone 10, and the bone raising device 50 is fixed in the alveolar bone 10. . The fixing seat 56 can be locked or engaged with a positioning member 60 to fix a titanium metal mesh or a coating film 30 of the regenerated film. The fixed root 54 has a predetermined length, typically about 2-4 mm. During the bone grafting operation, since the fixed root portion 54 has a predetermined length, and the body 52 and the fixed root portion 54 meet to form a step portion 53, the physician screws the fixed root portion 54 of the bone raising device 50 with a wrench or a special tool. When the alveolar bone 10 is inside, the fixed root portion 54 can be screwed in until the step portion 53 bears against the alveolar bone 10. Therefore, the physician screwed in the fixed root 54 to the tooth In the case of the trough 10, the depth of the fixed root portion 54 is measured without a time constant to determine whether the fixed root portion 54 needs to be screwed in again, and can be screwed into place at one time. In addition to greatly reducing the operation time, this design can also reduce the chance of surgical failure due to insufficient or too much screwing of the fixed root 54.
請再參考第2圖，將固定根部54旋入至齒槽骨10後，本體52與固定座56於齒槽骨10上提供一所需支撐高度及一固定處，以支撐及固定一包覆膜30，如鈦金屬網或再生膜。將固定根部54旋入至齒槽骨10後，將所需之鈦金屬網或再生膜之包覆膜30置放於固定座56上，再以定位元件60鎖合或扣合於固定座56上，而將包覆膜30加以固定及定位，再將牙齦皮瓣覆蓋在包覆膜30上，待其固定後再填充骨粉40。亦可先填充骨粉40，再將所需之鈦金屬網或再生膜之包覆膜30置放於固定座56及已填充骨粉40上，再以定位元件60鎖合或扣合於固定座56上，而將包覆膜30加以固定及定位，再將牙齦皮瓣覆蓋在鈦金屬網或再生膜30上。因該本體52與固定座56可增加包覆膜30架設的高度及寬度，讓填充的骨粉40可確實包覆外露之人工牙根20表面並達理想植骨高度，且定位元件60鎖合或扣合於固定座56上，將包覆膜30加以固定及定位，因而不需再縫合牙齦皮瓣與包覆膜30，或以固定釘32將包覆膜30固定於齒槽骨10上。此方式確實解決不易將牙齦皮瓣與包覆膜30加以縫合，或確實以固定釘32將包覆膜30固定於齒槽骨10上之缺失。 Referring to FIG. 2 again, after the fixed root portion 54 is screwed into the alveolar bone 10, the body 52 and the fixing base 56 provide a required supporting height and a fixing portion on the alveolar bone 10 to support and fix a covering. A membrane 30, such as a titanium mesh or a regenerated membrane. After the fixed root portion 54 is screwed into the alveolar bone 10, the desired titanium metal mesh or the film of the regenerated film 30 is placed on the fixing seat 56, and then locked or fastened to the fixing seat 56 by the positioning member 60. Upper, the cover film 30 is fixed and positioned, and the gingival flap is covered on the cover film 30, and then the bone powder 40 is filled after being fixed. The bone powder 40 may be first filled, and then the desired titanium metal mesh or the regenerated film coating film 30 is placed on the fixing seat 56 and the filled bone powder 40, and then locked or fastened to the fixing seat 56 by the positioning member 60. Above, the cover film 30 is fixed and positioned, and the gingival flap is covered on the titanium metal mesh or the regeneration film 30. Because the body 52 and the fixing seat 56 can increase the height and width of the covering film 30, the filled bone powder 40 can surely cover the surface of the exposed artificial root 20 and reach the ideal bone height, and the positioning component 60 is locked or buckled. The cover film 30 is fixed and positioned on the fixing base 56, so that the gingival flap and the cover film 30 need not be sutured, or the cover film 30 is fixed to the alveolar bone 10 by the fixing nails 32. This method does solve the problem that it is difficult to suture the gingival flap with the cover film 30, or to secure the cover film 30 to the alveolar bone 10 with the fixing nails 32.
再者，根據本發明之骨頭增高裝置50，本體52與固定座56於齒槽骨10上提供一所需支撐高度，且此所需支撐高度係根據患者之齒槽骨萎縮情況，及所需增高之齒槽骨而定，通常約為1-8 mm之各種支撐高度。根據本發明骨頭增高裝置50之另一特點，本體52可依需要，事先製作成不同高度，因而與固定座56共同提供具有各種不同所需支撐高度(1-8 mm)之骨頭增高裝置50。因此，醫師於行植骨手術時，可是先選擇所需支撐高度之骨頭增高裝置50，用以支撐及固 定包覆膜30，再以定位元件60鎖合或扣合於固定座56上，將包覆膜30加以固定及定位。於鈦金屬網或再生膜30與齒槽骨之間填充骨粉40後，再將牙齦皮瓣覆蓋上鈦金屬網或再生膜30。 Furthermore, in accordance with the bone augmentation device 50 of the present invention, the body 52 and the mount 56 provide a desired support height on the alveolar bone 10, and the required support height is based on the patient's alveolar bone atrophy and the desired Depending on the alveolar bone height, it is usually about 1-8 mm of various support heights. According to another feature of the bone augmentation device 50 of the present invention, the body 52 can be pre-formed to different heights as desired, thereby providing the bone augmentation device 50 with a variety of different desired support heights (1-8 mm) in conjunction with the mount 56. Therefore, when performing a bone graft operation, the physician first selects the bone height increasing device 50 of the required support height for supporting and solidifying. The coating film 30 is fixed, and then the positioning member 60 is locked or fastened to the fixing seat 56 to fix and position the coating film 30. After filling the bone powder 40 between the titanium metal mesh or the regenerated film 30 and the alveolar bone, the gingival flap is covered with a titanium metal mesh or a regenerated film 30.
於填充骨粉40與後齒槽骨10緊密結合後，再將包覆膜30與骨頭增高裝置50取出，以形成一具足夠高度之植骨後齒槽骨10，如第3圖所示。值得注意者，若使用再生膜作為包覆膜30，則再生膜會被吸收，僅須取出骨頭增高裝置50即可。然而，若使用鈦金屬網作為包覆膜30，則鈦金屬網之包覆膜30須與骨頭增高裝置50同時取出。請參考第4圖，因植骨後齒槽骨10已具有一足夠高度，再將人工植體之牙根20植入植骨後齒槽骨10中，待人工植體之牙根20與植骨後齒槽骨10緊密結合後，則形成堅固之植體，再於植體之基座上裝上牙冠。因植體深植於牙床骨內並與齒槽骨10緊密結合，故牙冠不需再以牙橋與自然牙齒相連，即能承受正常之咀嚼力量，功能與美觀上幾乎媲美自然牙。 After the packed bone powder 40 is tightly coupled to the posterior alveolar bone 10, the coating film 30 and the bone augmentation device 50 are removed to form a posterior bone 80 of the bone graft of sufficient height, as shown in FIG. It is to be noted that if a regenerated film is used as the coating film 30, the regenerated film is absorbed, and only the bone augmentation device 50 needs to be taken out. However, if a titanium mesh is used as the cover film 30, the cover film 30 of the titanium mesh must be taken out simultaneously with the bone augmentation device 50. Please refer to Fig. 4, because the posterior alveolar bone 10 has a sufficient height, and then implant the root of the artificial implant 20 into the posterior alveolar bone 10, after the root of the artificial implant 20 and the bone graft After the alveolar bone 10 is tightly coupled, a strong implant is formed, and the crown is attached to the base of the implant. Because the implant is deeply implanted in the bone of the gum and closely combined with the alveolar bone 10, the crown does not need to be connected with the natural tooth by the bridge, which can withstand the normal chewing force, and the function and appearance are almost comparable to the natural tooth.
