Description
本發明有關假牙裝置(prosthodontic device),尤指一種上部構造可拆卸的假牙裝置及相關的螺絲。 The present invention relates to a prosthodontic device, and more particularly to an upper structure detachable denture device and associated screws.
為了追求美觀或是改善口腔衛生等原因,許多人會選擇以植牙的方式來修補缺損的牙齒。傳統的植牙方式會利用黏著劑填充上部構造(suprastructure)與支座(abutment)之間的間隙,以使上部構造藉由黏著劑固定於支座上。 In order to pursue aesthetics or improve oral hygiene, many people choose to repair missing teeth by implanting them. Conventional dental implant methods use an adhesive to fill the gap between the suprastructure and the abutment so that the superstructure is fixed to the support by an adhesive.
然而,黏著劑一旦固化之後,便很難將上部構造從支座上移除,導致假牙周邊容易因為不易徹底清潔而產生牙周病,進而縮短了假牙的使用期限。倘若以物理方式強迫對上部構造施加力量以將上部構造從支座上移除,則很容易造成上部構造的結構或外觀受損,或是造成支座的結構受損。 However, once the adhesive is cured, it is difficult to remove the superstructure from the support, which causes the periodontal disease to be easily caused by the difficulty in thorough cleaning, thereby shortening the service life of the denture.

圖1為本發明一實施例的可拆卸假牙裝置100簡化後的剖面示意圖。如圖1所示,可拆卸假牙裝置100包含一支座(abutment)110、一上部構造(suprastructure)120、以及一螺絲(screw)130。支座110用於連接嵌入齒槽骨(bone)102中的一牙科植體(implant)104,且包含一支座接合部(abutment collar)111及一中空腔體(hollow chamber)112。上部構造120設置有一容置區(receiving region)121及圍繞容置區121的內側面(inner surface)122。螺絲130包含一螺絲頭(screw head)132與一螺桿(screw rod)134。在本實施例中,支座110的中空腔體112具有一開孔113及一外表面114,且中空腔體112的支座壁(abutment wall)115上設有一螺絲孔(screw hole)。 1 is a simplified cross-sectional view of a detachable denture device 100 in accordance with an embodiment of the present invention. As shown in FIG. 1, the detachable denture device 100 includes an abutment 110, an upper structure 120, and a screw 130. The support 110 is for attaching a dental implant 104 embedded in the bone 102 and includes an abutment collar 111 and a hollow chamber 112. The upper structure 120 is provided with a receiving region 121 and an inner surface 122 surrounding the receiving portion 121. The screw 130 includes a screw head 132 and a screw rod 134. In this embodiment, the hollow cavity 112 of the support 110 has an opening 113 and an outer surface 114, and a screw hole is formed on the abutment wall 115 of the hollow cavity 112.
如圖1所示,可經由中空腔體112上的開孔113將一支座螺絲(abutment screw)140伸入中空腔體112中,並將支座螺絲140貫穿支座接合部111以鎖入牙科植體104中,藉此將支座110固定在牙科植體104上。 As shown in FIG. 1, an abutment screw 140 can be inserted into the hollow cavity 112 through the opening 113 in the hollow cavity 112, and the abutment screw 140 can be inserted through the abutment joint 111 to lock in. In the dental implant 104, the support 110 is thereby secured to the dental implant 104.
以下將搭配圖2至圖3來進一步說明螺絲130的實施方式。圖2為本發明的螺絲130的一實施例簡化後的外觀示意圖。圖3為本發明的螺絲130的一實施例簡化後的側面示意圖。 Embodiments of the screw 130 will be further described below in conjunction with FIGS. 2 through 3. 2 is a simplified schematic view of an embodiment of a screw 130 of the present invention. 3 is a simplified side elevational view of an embodiment of a screw 130 of the present invention.
如圖2及圖3所示,螺絲頭132包含一接觸部(contact member)222與一導引部(guiding member)224。接觸部222具有一頂面226,導引部224位於接觸部222與螺桿134之間,且導引部224具有一導角(chamfer)結構。螺桿134上設置有螺紋(screw thread)230。 As shown in FIGS. 2 and 3, the screw head 132 includes a contact member 222 and a guiding member 224. The contact portion 222 has a top surface 226, and the guiding portion 224 is located between the contact portion 222 and the screw 134, and the guiding portion 224 has a chamfer structure. A screw thread 230 is disposed on the screw 134.
在圖2的實施例中,螺絲頭132的接觸部222的側面形狀為矩形。如圖2所示,螺絲頭132上還設置有一工具槽(tool slot)228。實作上,工具槽228的形狀可以但不侷限於一字形、十字形、三角形、六角形或是星形,使操作者可利用對應的螺絲起子等手工具***工具槽228中,以將螺絲130鎖入前述中空腔體112的支座壁115上的螺絲孔。另外,工具槽228還可設計成貫穿整個螺絲130,以節省製作螺絲130所需的物料量。 In the embodiment of Fig. 2, the side surface of the contact portion 222 of the screw head 132 is rectangular in shape. As shown in FIG. 2, a screw slot 228 is further disposed on the screw head 132. In practice, the shape of the tool slot 228 can be, but is not limited to, a shape of a letter, a cross, a triangle, a hexagon, or a star, so that the operator can insert the tool into the tool slot 228 by using a corresponding screwdriver or the like to screw the screw. 130 is screwed into a screw hole in the seat wall 115 of the aforementioned hollow body 112. Additionally, the tool slot 228 can also be designed to extend throughout the screw 130 to save the amount of material needed to make the screw 130.
請參考圖4至圖7,其所繪示為將螺絲130裝設到支座110的支座壁115上的方法的一實施例簡化後的示意圖。 Please refer to FIG. 4 to FIG. 7 , which are simplified schematic views of an embodiment of a method for mounting the screw 130 to the support wall 115 of the support 110 .
圖4為本發明的支座110的一實施例簡化後的剖面示意圖。在本實施例中,支座110的支座接合部111上設置有貫穿支座接合部111的一支座螺絲孔(abutment screw hole)416。 4 is a simplified cross-sectional view of an embodiment of a support 110 of the present invention. In the present embodiment, the abutment screw hole 416 penetrating the abutment joint portion 111 is provided on the abutment joint portion 111 of the abutment 110.
如圖5所示,要將螺絲130裝設到支座110的支座壁115上前,可先在中空腔體112的支座壁115上形成一螺絲孔517。實作上,可依螺絲130的螺桿134的長度來決定螺絲孔517的深度。例如,在某些實施例中,螺絲孔517可以用沒有貫穿支座壁115的盲孔來實現。在其他實施例中,螺絲孔517則可以用貫穿支座壁115的穿孔來實現。 As shown in FIG. 5, before the screw 130 is mounted on the support wall 115 of the support 110, a screw hole 517 can be formed in the support wall 115 of the hollow body 112. In practice, the depth of the screw hole 517 can be determined by the length of the screw 134 of the screw 130. For example, in some embodiments, the screw holes 517 can be implemented with blind holes that do not extend through the seat wall 115. In other embodiments, the screw holes 517 can be implemented with perforations that extend through the seat wall 115.
接著,如圖6所示,可利用適當的工具在螺絲孔517中形成尺寸及形狀都與螺絲130的導引部224相配合的一導引區(guiding region)618。例如,本實施例中的導引區618為圓形,導引區618的直徑與螺絲130的導引部224的直徑相同或是略大於導引部224的直徑,且導引區618及導引部224兩者的直徑都大於螺桿134的直徑。 Next, as shown in FIG. 6, a guiding region 618 having a size and shape matching the guiding portion 224 of the screw 130 can be formed in the screw hole 517 by a suitable tool. For example, the guiding area 618 in this embodiment is circular, and the diameter of the guiding area 618 is the same as or slightly larger than the diameter of the guiding portion 224 of the screw 130, and the guiding area 618 and the guiding Both the diameters of the lead portions 224 are larger than the diameter of the screw 134.
在將螺絲130裝設到前述支座壁115上的螺絲孔517時,導引部224的導角結構與導引區618之間的搭配,可輔助操作者將螺絲130更容易且更精準的鎖入螺絲孔517中,以降低螺絲130偏移的問題。 When the screw 130 is mounted to the screw hole 517 on the support wall 115, the alignment between the guide structure of the guiding portion 224 and the guiding portion 618 can assist the operator to make the screw 130 easier and more accurate. Lock into the screw hole 517 to reduce the problem of the screw 130 being offset.
當螺絲130設置於螺絲孔517中時,螺絲頭132的局部會從中空腔體112的外表面114向外突出。例如,如圖7所示,當螺絲130設置於螺絲孔517中時,導引部224會位於導引區618中,且接觸部222會從中空腔體112的外表面114向外突出。 When the screw 130 is disposed in the screw hole 517, a portion of the screw head 132 may protrude outward from the outer surface 114 of the hollow cavity 112. For example, as shown in FIG. 7, when the screw 130 is disposed in the screw hole 517, the guiding portion 224 may be located in the guiding portion 618, and the contact portion 222 may protrude outward from the outer surface 114 of the hollow cavity 112.
當上部構造120套住支座110時,中空腔體112的外表面114的局部區域會與上部構造120的內側面122的局部區域相接觸,且螺絲頭132會抵住內側面122的相對側,以施加一正向力到內側面122上,藉此使上部構造120以可卸除方式卡合在支座110上。 When the upper structure 120 is seated on the support 110, a partial area of the outer surface 114 of the hollow body 112 will contact a partial area of the inner side 122 of the upper structure 120, and the screw head 132 will abut the opposite side of the inner side 122. To apply a positive force to the inner side surface 122, whereby the upper structure 120 is removably snapped onto the support 110.
例如,圖8繪示將可拆卸假牙裝置100固定在牙科植體104上的方法的一實施例簡化後的示意圖。如前所述,操作者可經由開孔113將支座螺絲140伸入支座110的中空腔體112中,接著將支座螺絲140穿過支座接合部111的支座螺絲孔416並鎖入牙科植體104中,藉此將支座110固定在牙科植體104上。 For example, FIG. 8 illustrates a simplified schematic diagram of one embodiment of a method of securing a removable denture device 100 to a dental implant 104. As previously mentioned, the operator can extend the abutment screw 140 into the hollow cavity 112 of the abutment 110 via the opening 113, and then pass the abutment screw 140 through the abutment screw hole 416 of the abutment engagement portion 111 and lock The dental implant 104 is inserted into the dental implant 104 thereby securing the support 110 to the dental implant 104.
接著,操作者只需要將上部構造120的容置區121對準支座110,並將上部構造120往支座110的方向下壓以套住支座110,中空腔體112的外表面114的局部區域便會與上部構造120的內側面122的局部區域相接觸。此時,螺絲頭132的接觸部222便會抵住容置區121的內側面122的相對側,以施加正向力到內側面122上。如此一來,便可藉由中空腔體112的外表面114與上部構造120的內側面122之間的摩擦力,以及螺絲頭132的接觸部222與容置區121的內側面122間的應力,輕易將上部構造120以可卸除方式卡合在支座110上。 Next, the operator only needs to align the accommodating area 121 of the upper structure 120 with the pedestal 110 and press the upper structure 120 downwardly to the pedestal 110 to cover the pedestal 110, the outer surface 114 of the hollow body 112. The partial area will be in contact with a partial area of the inner side 122 of the upper structure 120. At this time, the contact portion 222 of the screw head 132 will abut against the opposite side of the inner side surface 122 of the accommodating portion 121 to apply a positive force to the inner side surface 122. In this way, the friction between the outer surface 114 of the hollow body 112 and the inner side surface 122 of the upper structure 120, and the stress between the contact portion 222 of the screw head 132 and the inner side surface 122 of the accommodating portion 121 can be achieved. The upper structure 120 is easily removably snapped onto the support 110.
倘若日後需要將上部構造120與支座110分離時,操作者只需對上部構造120施加適當的力量往離開支座110的方向推,便可克服上部構造120與支座110及螺絲130兩者間的摩擦力而將上部構造120與支座110分離,且不會損傷上部構造120與支座110的結構或外觀。 If the upper structure 120 needs to be separated from the support 110 in the future, the operator only needs to apply appropriate force to the upper structure 120 to push away from the support 110, thereby overcoming the upper structure 120 and the support 110 and the screw 130. The friction between the upper structure 120 and the support 110 is separated without damaging the structure or appearance of the upper structure 120 and the support 110.
因此,前述藉由螺絲130來卡合上部構造120與支座110的方式,有助於進行可拆卸假牙裝置100周邊組織的清潔、消毒、或治療、有助進行可拆卸假牙裝置100與鄰近牙齒106之間的間隙的清潔或治療、也有助於進行上部構造120的修復或更換。 Therefore, the manner in which the upper structure 120 and the support 110 are engaged by the screw 130 facilitates cleaning, disinfection, or treatment of the tissue surrounding the detachable denture device 100, and facilitates the detachable denture device 100 and adjacent teeth. Cleaning or treatment of the gap between 106s also facilitates repair or replacement of the superstructure 120.
請注意,當上部構造120卡合在支座110上時,螺絲130的螺絲頭132只會抵住上部構造120的容置區121的內側面,但螺絲130不會貫穿上部構造120,所以螺絲130不會外露到上部構造120之外,也不會破壞上部構造120的結構及完整性。 Please note that when the upper structure 120 is engaged on the support 110, the screw head 132 of the screw 130 only abuts against the inner side of the accommodating area 121 of the upper structure 120, but the screw 130 does not penetrate the upper structure 120, so the screw 130 will not be exposed to the superstructure 120 and will not damage the structure and integrity of the superstructure 120.
另外,並非任何形狀、尺寸的螺絲都能實現前述螺絲130的功能。事實上,螺絲130的形狀及尺寸要經過特別設計,才能被更廣泛地應用在不同的支座與上部構造之間,以下將對螺絲130的實施方式做進一步說明。 In addition, the screw of any shape and size can realize the function of the aforementioned screw 130. In fact, the shape and size of the screw 130 is specifically designed to be more widely used between different supports and upper configurations. The embodiment of the screw 130 will be further described below.
實作上,要對螺絲130的螺桿134的長度進行適當的設計,才能避免對前述支座螺絲140的裝設或卸除造成阻礙。 In practice, proper design of the length of the screw 134 of the screw 130 is to avoid obstructing the installation or removal of the aforementioned seat screw 140.
例如,在某些實施例中,可將螺桿134的長度設計成小於中空腔體112的內徑的一半。 For example, in certain embodiments, the length of the screw 134 can be designed to be less than half the inner diameter of the hollow cavity 112.
在另一些實施例中,可將螺桿134的長度設計成略小於中空腔體112的支座壁115的厚度。 In other embodiments, the length of the screw 134 can be designed to be slightly less than the thickness of the abutment wall 115 of the hollow body 112.
在部分實施例中,則可將螺桿134的長度設計成小於中空腔體112的支座壁115的厚度的150%。 In some embodiments, the length of the screw 134 can be designed to be less than 150% of the thickness of the abutment wall 115 of the hollow cavity 112.
經過多次試驗,發現將螺桿134的長度設計成介於0.5毫米(millimeter)至3.5毫米之間,可支援最多種既有的支座結構,應用的範圍最廣。 After many trials, it has been found that the length of the screw 134 is designed to be between 0.5 millimeters and 3.5 millimeters, supporting the widest variety of existing support structures and the widest range of applications.
另外,也可對螺桿134上的螺紋圈數(thread turns)或是螺距進行適當的設計,以提升螺絲130與前述支座壁115上的螺絲孔517鎖固時的穩定性。 Alternatively, the thread turns or pitches on the screw 134 may be appropriately designed to improve the stability of the screw 130 when the screw holes 517 on the seat wall 115 are locked.
例如,經過測試,發現將螺桿134上的螺紋圈數設計成介於1.5至6之間,可有效提升螺絲130與螺絲孔517間的緊密度並同時避免螺絲孔517的內螺紋受損,藉此可延長螺絲130的使用期限。 For example, after testing, it was found that the number of threads on the screw 134 is designed to be between 1.5 and 6, which can effectively improve the tightness between the screw 130 and the screw hole 517 while avoiding damage to the internal thread of the screw hole 517. This can extend the life of the screw 130.
另外,將螺桿134的螺距設計成介於0.1毫米至1.0毫米之間的方式,也能有效提升螺絲130與螺絲孔517間的緊密度並同時避免螺絲孔517的內螺紋受損。 Further, by designing the pitch of the screw 134 to be between 0.1 mm and 1.0 mm, the tightness between the screw 130 and the screw hole 517 can be effectively improved while the internal thread of the screw hole 517 is prevented from being damaged.
實作上,螺絲頭132的直徑最好設計成介於0.5至3.0毫米之間,以提供較佳的卡合效果。 In practice, the diameter of the screw head 132 is preferably designed to be between 0.5 and 3.0 mm to provide a better snap fit.
請注意,前述實施例中的支座110的形狀只是一示範性的實施例,並非侷限本發明的實際實施方式。例如,支座110的外型或是中空腔體112的形狀、尺寸,都可依實際需要而加以調整。 It should be noted that the shape of the support 110 in the foregoing embodiment is merely an exemplary embodiment and is not intended to limit the actual implementation of the present invention. For example, the shape of the support 110 or the shape and size of the hollow body 112 can be adjusted according to actual needs.
由前述說明可知,操作者只需要將上部構造120的容置區121對準支座110,並將上部構造120往支座110的方向下壓以套住支座110,便可藉由中空腔體112的外表面114與上部構造120的內側面122之間的摩擦力,以及螺絲頭132的接觸部222與容置區121的內側面122間的應力,輕易地將上部構造120以可卸除方式卡合在支座110上。 It can be seen from the foregoing description that the operator only needs to align the accommodating area 121 of the upper structure 120 with the pedestal 110 and press the upper structure 120 downward in the direction of the pedestal 110 to cover the pedestal 110, thereby obtaining a hollow cavity. The friction between the outer surface 114 of the body 112 and the inner side surface 122 of the upper structure 120, and the stress between the contact portion 222 of the screw head 132 and the inner side surface 122 of the receiving portion 121, facilitates detachability of the upper structure 120. The split mode is engaged on the support 110.
倘若日後需要將上部構造120與支座110分離時,操作者也只需對上部構造120施加適當的力量往離開支座110的方向推,便可將上部構造120與支座110分離,且不會損傷上部構造120與支座110的結構或外觀。 If the upper structure 120 needs to be separated from the support 110 in the future, the operator only needs to apply appropriate force to the upper structure 120 to push away from the support 110, so that the upper structure 120 can be separated from the support 110, and The structure or appearance of the superstructure 120 and the support 110 may be damaged.
因此,前述藉由螺絲130來卡合上部構造120與支座110的方式,有助於進行可拆卸假牙裝置100周邊組織的清潔、消毒、或治療、有助進行可拆卸假牙裝置100與鄰近牙齒106之間的間隙的清潔或治療、也有助於進行上部構造120的修復或更換。 Therefore, the manner in which the upper structure 120 and the support 110 are engaged by the screw 130 facilitates cleaning, disinfection, or treatment of the tissue surrounding the detachable denture device 100, and facilitates the detachable denture device 100 and adjacent teeth. Cleaning or treatment of the gap between 106s also facilitates repair or replacement of the superstructure 120.
在前述的部分實施例中,螺絲頭132的接觸部222的側面形狀是設計為矩形。這樣的設計方式並非簡單的設計選擇,而是經過測試發現這樣的螺絲頭設計方式可提供較多的應用彈性給操作者,使得操作者可依實際需要適度修整接觸部222的形狀,以更適應於上部結構120的容置區121的形狀、或是上部結構120與支座110之間的間隙大小,藉以提升上部結構120與支座110之間的卡合效果。 In some of the foregoing embodiments, the side shape of the contact portion 222 of the screw head 132 is designed to be rectangular. Such a design method is not a simple design choice, but it has been found that such a screw head design method can provide more application flexibility to the operator, so that the operator can appropriately trim the shape of the contact portion 222 according to actual needs, thereby being more suitable. The shape of the accommodating area 121 of the upper structure 120 or the size of the gap between the upper structure 120 and the support 110 is used to enhance the engaging effect between the upper structure 120 and the support 110.
前述的螺絲130的結構適用於許多不同結構的支座,具有相當廣泛的應用彈性。 The aforementioned structure of the screw 130 is suitable for a plurality of supports of different structures and has a wide range of application flexibility.
再者,由於前述的螺絲130是隱藏於上部構造120的容置區121內,不會外露到上部構造120之外,固能受到上部構造120的保護,而不容易受損或生鏽,可有效延長可拆卸假牙裝置100的使用期限。 Moreover, since the aforementioned screw 130 is hidden in the accommodating area 121 of the upper structure 120 and is not exposed to the upper structure 120, the solid energy is protected by the upper structure 120, and is not easily damaged or rusted. Effectively extending the life of the detachable denture device 100.
另外,由於螺絲130不會外露到上部構造120之外,所以不會影響到美觀,也不會引發患者口腔內的異物感,可改善假牙的使用舒適度。 In addition, since the screw 130 is not exposed to the outer structure 120, it does not affect the appearance, and does not cause a foreign body sensation in the patient's mouth, and can improve the comfort of use of the denture.
