Description

TECHNICAL FIELD

[0001] The present invention relates to a support device, in particular to a support device for supporting a biological membrane and a method of using the same. BACKGROUND

[0002] In the bone regeneration procedure before dental implantation, such as guided bone regeneration (GBR), a regeneration membrane is used to cover the defect area to define the volume and shape of the bone to be grown. There are mainly two types of regeneration membranes, one of which is an absorbable membrane that can be absorbed by the human body, and the other is a non-absorbable membrane that cannot be absorbed by the human body and needs to be removed by secondary surgery. Since the material of the absorbable membrane is soft, when a large range of defect area is encountered, a support structure is often needed to support the absorbable membrane to support the required bone filling space. The common methods for supporting the regeneration membrane mainly include titanium mesh support method and long bone screw support method.

[0003] The titanium mesh support method has the following disadvantages:

[0004] Since the titanium mesh is covered with a plurality of through holes, when the titanium mesh is removed after bone filling, the soft tissue will grow into the holes and adhere to the titanium mesh, making it difficult to remove the titanium mesh.

[0005] In addition, since the holes are distributed on the titanium mesh, the titanium mesh presents a non-smooth state with unevenness, and the hole edges defined by the titanium mesh are sharp, so when the titanium mesh is bent into a specific shape, the bending corner of the titanium mesh is relatively rough. This can cause the titanium mesh to break through the thin area of the gum during the healing period after surgery, exposing the bending corner of the titanium mesh to the gum, which can lead to bone loss and tissue infection, which is the main cause of the failure of the aforementioned surgery.

[0006] Furthermore, some titanium meshes are designed to have a fixed shape and size, and are combined with a locking member to form a support device. If the range of the defect area is too large, multiple sets of the support device need to be used at the same time, which is more complicated and inconvenient to use.

[0007] The long bone screw support method has the following disadvantages:

[0008] The support method needs to lock a plurality of long bone nails on a tooth socket first, and then cover the regenerative membrane on the screw head of each long bone nail, so that the regenerative membrane is supported by the long bone nail. Because the tooth socket is often atrophied, the length of the tooth socket that can lock each long bone nail is limited. Therefore, when the part of each long bone nail that is exposed outside the tooth socket is much longer than the part that is locked in the tooth socket, each long bone nail is easily shaken by external force. In addition, the area of the screw head of each long bone nail supporting the regenerative membrane is small, resulting in poor stability of each long bone nail supporting the regenerative membrane. Therefore, the regenerative membrane is easily shaken and causes the bone powder covered thereby to move and fail to form bone, thereby leading to the failure of bone regeneration. SUMMARY

[0009] Therefore, an object of the present application is to provide a support device that can overcome at least one of the drawbacks of the prior art.

[0010] The object and solution to the problems of the prior art are achieved by the following technical solutions. The support device according to the present application is suitable for supporting a biological membrane.

[0018] The support device of the present application, the intermediate section has two side surfaces spaced apart along a thickness direction, the thickness direction is perpendicular to the length direction and the width direction, the arc surface of each end section protrudes out of the side surface and is connected between the side surfaces.

[0019] The support device of the present application, a first thickness of the intermediate section along the thickness direction is less than a second thickness of each end section along the thickness direction.

[0020] The support device of the present application, the first thickness is 0.5 mm, the second thickness is 1 mm, and the distance of the arc surface of each end section protruding out of the corresponding side surface is 0.25 mm.

[0021] The support device of the present application, each end section has two end surfaces spaced apart along the length direction, and each end section is formed with a through hole extending between the end surfaces along the length direction.

[0022] The support device of the present application, the intermediate section has two first end surfaces spaced apart along the length direction, each end section has two second end surfaces spaced apart along the length direction, and the intermediate section and the end sections jointly define a through hole extending between the first end surfaces and the second end surfaces along the length direction.

[0023] The support device of the present application, a width of the support strip along the width direction is less than or equal to 3 mm, and a thickness of the support strip along a thickness direction is greater than or equal to 1 mm, the thickness direction being perpendicular to the length direction and the width direction.

[0024] The support device of the present application further comprises a clamping sheet detachably clamped to the support strip, the clamping sheet being used to hold the biofilm to the support strip.

[0025] The support device of the present application, the clamping sheet comprises a main sheet body and two elastic sheet bodies respectively flexibly connected to opposite ends of the main sheet body, the elastic sheet bodies being used to clamp the biofilm and the arc surface of the end section, each elastic sheet body has a free end, a spacing of the free ends of the elastic sheet bodies along the width direction is less than a width of the support strip along the width direction, the free ends being used to press the biofilm against the corresponding arc surface and slide along the corresponding arc surface to cause the elastic sheet bodies to be flexibly deformed relative to the main sheet body.

[0026] An object of the present application is to provide a use method of a support device capable of overcoming at least one disadvantage of the background art.

[0027] The purpose and background of the present application is to solve the technical problems by using the following technical solutions. The support device is suitable for being installed at a bone defect structure of a human body, and is used for supporting a biological membrane.

[0028] The use method of the support device comprises the following steps:

[0029] The support device comprises a support strip, the support strip is in a long strip shape and extends along a length direction, and the support strip comprises at least one circular arc surface extending along the length direction.

[0030] The support strip is installed at the bone defect structure and at a specific position corresponding to the recessed space, and then the support strip is locked to the bone defect structure.

[0031] The biological membrane is covered on the bone defect structure, so that the biological membrane covers the recessed space and the support strip, and the support strip supports the biological membrane through the circular arc surface.

[0032] In the step of providing the support device, the support strip comprises two circular arc surfaces located at opposite ends, and the support device further comprises a clamping piece. After the step of covering the biological membrane, the use method further comprises a step of holding the biological membrane, in which the biological membrane and the circular arc surface are clamped by the clamping piece, so as to hold the biological membrane on the support strip.

[0033] In the step of installing the support strip, the support strip corresponds to and spans an angle corner part of the recessed space, and the angle corner part is between a buccal side and an apical end of the bone defect structure.

[0034] In the step of installing the support strip, the support strip is first bent into an inverted U shape, so that the support strip forms a top support part and two side support parts respectively located at opposite ends of the top support part, and then the side support parts are respectively locked to the buccal side and the lingual side of the bone defect structure.

[0035] The support bar supports the biological membrane by the smooth arc surface, avoids the gum being pierced by any one of the end segments during the healing period, prevents the exposure of the bone graft area and causes the operation failure. In addition, the biological membrane can be fixed on the support bar by the design of the clamping piece, so as to prevent the shaking of the biological membrane relative to the support bar. Since the support bar is in a long strip shape and can cross the corner part, the user can achieve the effect of stably supporting the biological membrane by using a single set of the support device, and the convenience during the assembly and use and the postoperative disassembly is improved. The support bar can be bent into an inverted U shape and support the biological membrane, so as to achieve the effect of stably supporting the biological membrane. Since the support bar is only formed with the perforations for the bone nails to pass through in the middle segment without other holes, the gum in the healing period can be prevented from growing into the support bar and adhering to it. In this way, when the gum heals, the groove is cut on the gum, the clamping piece is detached from the support bar, and then the bone nail is rotated to conveniently and quickly remove the support bar. By retaining the support bar in the specific position, the bone resorption condition of the buccal side can be reduced. BRIEF DESCRIPTION OF DRAWINGS

[0053] The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0054] Before the present application is described in detail, it is to be understood that like elements are denoted by like numbers in the figures.

[0055] Referring to Figure 1 , the first embodiment of the support device 100 of the present application comprises a support bar 1 and a holding piece 2.

[0056] Referring to Figure 1 and Figure 2The support strip 1 is made by casting or CNC machining, and is made of titanium metal. The support strip 1 is long and extends along a length direction D1. The support strip 1 includes a middle section 11 and two end sections 12. The middle section 11 is a sheet and extends along the length direction D1. The middle section 11 has two first end faces 110 and two side faces 111. The first end faces 110 are spaced apart along the length direction D1. The side faces 111 are spaced apart along a thickness direction D2 perpendicular to the length direction D1 and are connected to opposite sides of the first end faces 110. The end sections 12 are formed at opposite ends of the middle section 11 and are spaced apart along a width direction D3 perpendicular to the length direction D1 and the thickness direction D2. Each of the end sections 12 is cylindrical and has two second end faces 120 and an arc surface 121. The second end faces 120 are spaced apart along the length direction D1 and are connected to the first end faces 110, respectively. The arc surface 121 extends along the length direction D1 and is connected between the second end faces 120. The arc surface 121 protrudes from the side faces 111 and is connected between the side faces 111, so as to support a biofilm 4 (as shown in Figure 6

[0057] A width W of the support strip 1 along the width direction D3 is less than or equal to 3 mm, and a thickness T of the support strip 1 along the thickness direction D2 is greater than or equal to 1 mm. In the first embodiment, the width W is 3 mm, and the thickness T is 1 mm. Since the thickness T of the support strip 1 is thin, the support strip 1 is flexible. More specifically, since the arc surface 121 protrudes from the side faces 111, a first thickness T1 of the middle section 11 along the thickness direction D2 is less than a second thickness T2 of each of the end sections 12 along the thickness direction D2. In the first embodiment, the first thickness T1 is 0.5 mm, and the second thickness T2 is the thickness T, i.e., 1 mm. A distance D by which the arc surface 121 of each of the end sections 12 protrudes from the corresponding side face 111 is 0.25 mm. In this way, the support strip 1 can be easily bent to form a desired specific shape, while maintaining sufficient support strength.

[0058] ​The clamping piece 2 is made of titanium metal. The clamping piece 2 is detachably clamped on the support bar 1 and used to hold the biological membrane 4 on the support bar 1. The clamping piece 2 comprises a main piece body 21 and two elastic piece bodies 22. The main piece body 21 is matched with the corresponding side surface 111 of the middle section 11, and is used to contact and press the biological membrane 4 and has an outer side surface 211 and an inner side surface 212. The elastic piece bodies 22 are respectively curvedly connected to the opposite ends of the main piece body 21 and are spaced apart along the width direction D3, and are respectively used to clamp the arc-shaped surface 121 of the end section 12. Each elastic piece body 22 is curvedly extended outward from one end of the main piece body 21 by a distance and protrudes out of the outer side surface 211, and then curvedly extended inward by a distance and protrudes out of the inner side surface 212, so that each elastic piece body 22 forms an arc-shaped structure matched with the corresponding arc-shaped surface 121. Each elastic piece body 22 is used to contact and press the biological membrane 4 and has a free end 221, and the distance S between the free ends 221 of the elastic piece bodies 22 along the width direction D3 is less than the width W. In this way, when each elastic piece body 22 is assembled on the corresponding end section 12, the free end 221 can contact and slide on the arc-shaped surface 121, so as to make each elastic piece body 22 bend and deform relative to the main piece body 21 and then be buckled on the corresponding end section 12.

[0059] The use method of the support device 100 will be described in detail below.

[0060] Referring to Figure 3 , the support device 100 (as shown in Figure 1 ) is suitable for being installed on a bone defect structure 3 of a human body and used to support the biological membrane 4 (as shown in Figure 6 ). The bone defect structure 3 is taken as an alveolar bone, and the bone defect structure 3 has a top end 31, a buccal side 32 and a lingual side 33. The top end 31 and the buccal side 32 of the bone defect structure 3 are recessed to form a recessed space 34, and the recessed space 34 has a corner portion 341 between the top end 31 and the buccal side 32.

[0061] Referring to Figure 4 , Figure 4 is a step flow chart of the use method of the support device 100 of the first embodiment, and the use method comprises the following steps: providing a support device step S1, installing a support bar step S2, covering a biological membrane step S3, and holding a biological membrane step S4.

[0062] Referring to Figure 1 and Figure 4In the providing support device step S1, the support device 100 includes the support bar 1 and the clamping piece 2.

[0063] Referring to Figure 3 , Figure 4 and Figure 5 , in the installing support bar step S2, the user needs to first punch a hole on the appropriate position of the middle section 11 of the support bar 1 by using a tool such as pliers, so as to form two through holes 112 on the middle section 11, which extend between the side faces 111 and are spaced apart along the length direction D1 and are respectively adjacent to the first end face 110 (as shown in Figure 1 ).

[0064] Then, the support bar 1 is placed on the bone defect structure 3 and corresponds to a specific position of the recessed space 34. In this first embodiment, the specific position refers to the position corresponding to the corner portion 341. For example, the arc surface 121 of the end section 12 of the support bar 1 is abutted against the buccal side 32 adjacent to the top end 31, so that the support bar 1 corresponds to the corner portion 341 and spans the corner portion 341. Subsequently, the two bone screws 5 are respectively threaded into the through holes 112 and are screwed into the buccal side 32, so as to lock the support bar 1 to the buccal side 32 of the bone defect structure 3. It should be noted that the support bar 1 can also be installed in the following two ways according to the needs, one of which is that the arc surface 121 of the support bar 1 is abutted against the top end 31 adjacent to the buccal side 32, and the support bar 1 is locked to the top end 31 of the bone defect structure 3 by the bone screws 5. The other way is that the arc surface 121 of the support bar 1 is abutted against the junction of the top end 31 and the buccal side 32, and the support bar 1 is locked to the junction of the top end 31 and the buccal side 32 of the bone defect structure 3 by the bone screws 5. In this way, the support bar 1 can also correspond to the corner portion 341 and span the corner portion 341.

[0065] The design of the support bar 1 by the end section 12 formed on the opposite end of the middle section 11 enables the support bar 1 to be locked to the bone defect structure 3 at the angle position as shown in Figure 5 , or the angle position after rotating 180 degrees around the center line of the middle section 11 extending along the length direction D1, thereby improving the convenience of assembly.

[0066] Referring to Figure 4 , Figure 6 and Figure 7In the covering biological membrane step S3, the biological membrane 4 is first covered on the lingual side 33 of the bone defect structure 3, and the biological membrane 4 is fixed on the lingual side 33 by sutures (not shown). Then, the bone powder 6 is filled into the recessed space 34. After the filling is completed, the biological membrane 4 is covered on the top end 31, the recessed space 34, the support strip 1 and the buccal side 32, so that the biological membrane 4 covers the recessed space 34 and the support strip 1. At this time, the support strip 1 supports the biological membrane 4 through the arc-shaped surfaces 121.

[0067] Referring to Figure 2 , Figure 4 , Figure 8 and Figure 9 In the holding biological membrane step S4, a lateral pressure F is applied to the clamping piece 2 to move it laterally toward the support strip 1. Since the interval S between the free ends 221 of the elastic sheet bodies 22 is smaller than the width W, the free ends 221 of the elastic sheet bodies 22 will contact the biological membrane 4 and press it against the corresponding arc-shaped surface 121 during the lateral movement of the clamping piece 2. Then, the free ends 221 of the elastic sheet bodies 22 will slide along the corresponding arc-shaped surface 121 to cause the elastic sheet bodies 22 to bend and deform relative to the main sheet body 21 and accumulate restoring elastic force. Since the elastic sheet bodies 22 partially protrude out of the outer side surface 211 of the main sheet body 21, the main sheet body 21 will slightly deform inwardly when the elastic sheet bodies 22 bend and deform relative to the main sheet body 21. When the free ends 221 of the elastic sheet bodies 22 pass the end of the corresponding arc-shaped surface 121 and separate from it, the elastic sheet bodies 22 will automatically snap onto the corresponding end section 12 by the action of the accumulated restoring elastic force, thereby enabling the elastic sheet bodies 22 to clamp the biological membrane 4 and the arc-shaped surface 121 to hold the biological membrane 4 on the support strip 1. The slight inward deformation of the main sheet body 21 enables the inner side surface 212 of the main sheet body 21 to press the corresponding part of the biological membrane 4 to tightly conform to the corresponding side surface 111 of the intermediate section 11. The shape of the elastic sheet bodies 22 cooperates with the corresponding arc-shaped surface 121 to enable the elastic sheet bodies 22 to press the corresponding part of the biological membrane 4 to tightly conform to the corresponding arc-shaped surface 121. In this way, the support strip 1 and the clamping piece 2 can have a larger contact area with the biological membrane 4 to improve the stability of holding the biological membrane 4.

[0068] By utilizing the design where the arcuate surfaces 121 of each end segment 12 protrude from the side surface 111 of the middle segment 11, when the support strip 1 faces the cheek side 32 with any one of its side surfaces 111 and is locked to the cheek side 32, the free ends 221 of each elastic sheet 22 can press the biomembrane 4 against the corresponding arcuate surface 121 and slide along the corresponding arcuate surface 121, allowing each elastic sheet 22 to be smoothly snapped into the corresponding end segment 12. This ensures that the clamping piece 2 is not affected by the assembly direction of the support strip 1, thereby improving the ease of assembly of the clamping piece 2.

[0069] It should be noted that in other embodiments of this first embodiment, each elastic sheet 22 may also be bent inward from one end of the main sheet 21 without protruding beyond the outer side 211 of the main sheet 21, so that after the clamping sheet 2 holds the biofilm 4 to the support strip 1, the biofilm 4 is spaced apart from the corresponding side 111 by a certain distance.

[0070] After the clamping piece 2 holds the biomembrane 4 to the support strip 1, it completely covers the biomembrane 4 and the support device 100 with a skin flap (not shown), and then the skin flap is sutured. In this way, after the gum heals, it can completely cover the biomembrane 4 and the support device 100.

[0071] See Figure 2 , Figure 8 and Figure 9 In this first embodiment, the support strip 1 supports the biomembrane 4 via its smooth, arc-shaped surface 121, preventing the gum from being punctured by any of the end segments 12 during the healing period, thus preventing the support strip 1 from exposing the bone graft area and causing surgical failure. Furthermore, since the support strip 1 only has sections for the bone screws 5 (such as...) formed in its middle segment 11... Figure 5 (As shown) the perforation 112 (as shown) Figure 3 (As shown) without any other holes, thus preventing soft tissue from growing into and adhering to the support strip 1 during the gum healing period. Therefore, after the gum has healed, a groove can be cut into the gum, the clamping piece 2 can be removed from the support strip 1, and then the bone screw 5 can be unscrewed, allowing for convenient and quick removal of the support strip 1. On the other hand, the design of the clamping piece 2 allows for very convenient and quick fixation of the biofilm 4 to the support strip 1, preventing the biofilm 4 from shifting relative to the support strip 1. Furthermore, since the support strip 1 is elongated and can span the corner 341 (as shown), Figure 3Therefore, the user can achieve the effect of firmly supporting the biological membrane 4 by using a single set of the support device 100, thereby improving the convenience of assembly and use and postoperative disassembly.

[0072] The support bar 1 structure of the support device 100 of the first embodiment can have the following different forms according to requirements:

[0073] One form is that the arc surface 121 of the end section 12 can be designed to protrude out of only one side surface 111 of the middle section 11, and the one side surface 111 can face the clamping piece 2 when the support bar 1 is assembled and used.

[0074] Another form is that the number of the end section 12 of the support bar 1 is one, and the arc surface 121 of the end section 12 can be designed to protrude out of the side surface 111 of the middle section 11 at the same time, and the end section 12 can face upward when the support bar 1 is assembled and used.

[0075] Another form is that the number of the end section 12 of the support bar 1 is one, and the arc surface 121 of the end section 12 can be designed to protrude out of only one side surface 111 of the middle section 11, and the end section 12 can face upward when the support bar 1 is assembled and used, and the one side surface 111 can face the clamping piece 2 when the support bar 1 is assembled and used.

[0076] It is particularly pointed out that in another implementation form of the first embodiment, the support device 100 can also only have the support bar 1. In the biological membrane holding step S4 in this implementation form, the biological membrane 4 can be fixed on the buccal side 32 by a suture (not shown in the figure), and the effect of holding the biological membrane 4 can also be achieved.

[0077] Referring to Figure 10 and Figure 11 , the second embodiment of the support device 100 of the present application has the same overall structure as the first embodiment, and the difference lies in the use method of the support device 100.

[0078] In the second embodiment, the recessed space 34 of the bone defect structure 3 is formed by the downward recess of the top end 31. In the installation support bar step S2 (as shown in Figure 4In the third embodiment, the support bar 1 is first bent into an inverted U-shape to form a top support portion 13 and two side support portions 14 located at opposite ends of the top support portion 13. The top support portion 13 is placed above and across the recessed space 34, and the side support portions 14 are respectively abutted against the buccal side 32 and the lingual side 33. Subsequently, the side support portions 14 are secured to the buccal side 32 and the lingual side 33 by the bone pegs 5, so that the support bar 1 is fixed to the bone defect structure 3. Then, the biological membrane 4 is covered on the support bar 1, the buccal side 32 and the lingual side 33, and the biological membrane 4 is held on the top support portion 13 of the support bar 1 by the clamping pieces 2 (as shown in Figure 9 ).

[0079] Since the side support portions 14 of the support bar 1 are secured to the buccal side 32 and the lingual side 33 by the bone pegs 5, the support bar 1 can be stably fixed to the bone defect structure 3 without being easily shaken. In addition, by bending the support bar 1 into an inverted U-shape, the support bar 1 can support the biological membrane 4 by the top support portion 13 and the side support portions 14 at the same time. Since the area of the support bar 1 supporting the biological membrane 4 is large, the support bar 1 can stably support the biological membrane 4. Compared with the long bone peg support method in the prior art, the shape of the bone powder 6 after growing into bone can be more accurately controlled.

[0080] Referring to Figure 12 and Figure 13 , the third embodiment of the support device 100 has the same overall structure and use method as the second embodiment, but differs in the number of the support devices 100.

[0081] In the third embodiment, the recessed space 34 of the bone defect structure 3 is recessed downward from the top end 31 and formed between the buccal side 32 and the lingual side 33, and the area of the recessed space 34 is large. In the step S1 of providing a support device (as shown in Figure 4 ), the number of the support devices 100 is multiple, and the number of the support devices 100 used is determined according to the area of the recessed space 34. In the step S2 of installing a support bar (as shown in Figure 4In the fourth embodiment of the present application, each of the end sections 12 of the support bar 1 is formed with a through hole 122 extending between the second end faces 120 along the length direction D1 (as shown in FIG. 12). In this way, the user can conveniently flatten each of the end sections 12 by using a tool, so that each of the end sections 12 can conform to a bone defect structure 3 with a large surface relief (as shown in FIG. 13).

[0082] Referring to Figure 14 , the fourth embodiment of the support device 100 of the present application has substantially the same overall structure and use method as the first embodiment, except for the structure of the support bar 1.

[0083] In the fourth embodiment, each of the end sections 12 of the support bar 1 is formed with a through hole 122 extending between the second end faces 120 along the length direction D1 (as shown in FIG. 12). In this way, the user can conveniently flatten each of the end sections 12 by using a tool, so that each of the end sections 12 can conform to a bone defect structure 3 with a large surface relief (as shown in FIG. 13). Figure 1 Figure 3 In the fourth embodiment, each of the end sections 12 of the support bar 1 is formed with a through hole 122 extending between the second end faces 120 along the length direction D1 (as shown in FIG. 12). In this way, the user can conveniently flatten each of the end sections 12 by using a tool, so that each of the end sections 12 can conform to a bone defect structure 3 with a large surface relief (as shown in FIG. 13).

[0084] Referring to Figure 15 , the fifth embodiment of the support device 100 of the present application has substantially the same overall structure and use method as the first embodiment, except for the structure of the support bar 1.

[0085] In the fifth embodiment, the middle section 11 and the end sections 12 of the support bar 1 together define a through hole 15 extending between the first end face 110 and the second end face 120 along the length direction D1 (as shown in FIG. 14). In this way, the user can conveniently flatten the middle section 11 and the end sections 12 by using a tool, so that the support bar 1 can conform to a bone defect structure 3 with a large surface relief (as shown in FIG. 15). Figure 1 Figure 3 In the fifth embodiment, the middle section 11 and the end sections 12 of the support bar 1 together define a through hole 15 extending between the first end face 110 and the second end face 120 along the length direction D1 (as shown in FIG. 14). In this way, the user can conveniently flatten the middle section 11 and the end sections 12 by using a tool, so that the support bar 1 can conform to a bone defect structure 3 with a large surface relief (as shown in FIG. 15).

[0086] Referring to Figure 16 , the sixth embodiment of the support device 100 of the present application has substantially the same overall structure and use method as the first embodiment, except for the structure of the support bar 1.

[0087] ​​In the sixth embodiment, the user can cut the two opposite ends of each of the end segments 12 to appropriate lengths by using the cutting tool, so that the first end surface 110 of the middle segment 11 protrudes from the second end surface 120 of each of the end segments 12 by an appropriate distance. In this way, the middle segment 11 can be attached to a bone defect structure 3 (as shown in FIG. 1) having a large surface relief by protruding from the portions of each of the end segments 12 corresponding to the side surface 111. Figure 3

[0088] Referring to FIG. 6, a seventh embodiment of the support device 100 of the present application has substantially the same overall structure as the first embodiment, but differs in the method of use. Figure 17

[0089] After the bone powder 6 in the first embodiment grows into bone in the recessed space 34 to complete the bone supplementing operation, a dental implant prosthesis operation will be performed subsequently. After long-term use, the implant will almost always face the condition of bone resorption at the buccal side 32, because the implant lacks periodontal ligaments like natural teeth, and cannot stimulate bone growth through the stimulation of the mechanoreceptors in the ligaments. Bone resorption at the buccal side 32 can cause many problems, such as food residue being difficult to clean, gum inflammation, and even peri-implantitis. Therefore, in the seventh embodiment, after the gums heal and grooves are cut in the gums, only the clamping pieces 2 (as shown in FIG. 6) are removed, and the support bar 1 is left in place without being removed, thereby reducing the condition of bone resorption at the buccal side 32. Figure 9

[0090] Referring to FIG. 6, in another implementation aspect of the seventh embodiment, in the step S2 of installing the support bar (as shown in FIG. 6), the user also punches holes in appropriate positions on the middle segment 11 of the support bar 1 by using the tool, such as pliers, to form a plurality of through holes 113 in the middle segment 11, which extend between the side surfaces 111 and are located between the perforations 112, and are spaced apart along the length direction D1. The through holes 113 allow soft tissue to grow in to improve the stability of the bond, thereby enabling the bone to cover the support bar 1 and stably bond therewith after the bone covers the support bar 1. In still another implementation aspect of the seventh embodiment, the first end surface 110, the side surface 111, the second end surface 120, and the arc-shaped surface 121 of the support bar 1 can also be subjected to surface treatment, such as sandblasting or acid etching, to increase the surface roughness and improve the adhesion of the bone, thereby enabling the bone to cover the support bar 1 and stably bond therewith after the bone covers the support bar 1. Figure 17 Figure 4

[0091] ​​​​​In summary, the support device 100 of the embodiments can support the biological membrane 4 by the smooth arc surface 121 of the support strip 1, so as to avoid the gum being pierced by the end section 12 during the healing period, and prevent the bone grafting area from being exposed to cause the surgery failure. In addition, the biological membrane 4 can be fixed on the support strip 1 by the design of the clamping piece 2, so as to prevent the biological membrane 4 from shaking relative to the support strip 1.
