Description

Support device

This model relates to a supporting device, in particular to a supporting device for supporting biofilm.

Bone regeneration before dental implantation, such as Guided Bone Regeneration (GBR), requires a regeneration membrane to cover the defect area to define the volume and type of bone that needs to be grown. There are mainly two types of the regenerated film, one of which is an absorbable film that can be absorbed by the human body, and the other is a non-absorbable film that cannot be absorbed by the human body and needs to be removed by a second operation. Since the material of the absorbable film is relatively soft, when encountering a large defect area, it is often necessary to support the absorbable film through a supporting structure to prop up the required bone space. Commonly used methods to support the regenerated membrane mainly include: titanium metal mesh support method, and long bone nail support method.

The titanium metal mesh support method has the following disadvantages:

Since the titanium mesh is covered with multiple through holes, when the titanium mesh is taken out after the bone filling is completed, it will stick to the titanium mesh because the soft tissue grows into the holes. As a result, the titanium metal mesh is not easy to be taken out.

In addition, because the holes are all over the titanium metal mesh, the titanium metal mesh presents an uneven and non-smooth state, and the titanium metal mesh defines the edge of each hole is sharp, therefore, the titanium metal mesh When bent into a specific shape, a bent corner of the titanium metal mesh is quite rough. This will make it possible for the thinner area of the gum to be pierced by the bent corner of the titanium metal mesh during the gum healing period after the operation, causing the bent corner to expose the gum, which will lead to bone loss and The condition of tissue infection is the main reason that causes the most frequent failure of the aforementioned surgery.

Furthermore, some of the titanium metal meshes are designed to have a fixed shape and size, and are combined with a fastener to jointly form a supporting device. If the area of the defect is too large, multiple sets of the supporting device must be used at the same time, which results in complicated and inconvenient use.

This long bone nail support method has the following disadvantages:

This support method requires multiple long bone nails to be locked on an alveolar bone first, and then the regenerated membrane is covered on a screw head of each long bone nail, so that the regenerated membrane is supported by the long bone nails . Because the alveolar bone often shrinks, the length of the alveolar bone that can lock the long bone nails is limited. Therefore, when the long bone nails are exposed outside the alveolar bone than the tooth is locked into the tooth When the part in the groove bone is too long, each of the long bone nails is easily affected by external force and shakes. In addition, the area of the screw head of each long bone screw supporting the regeneration membrane is small, resulting in poor stability of each long bone screw supporting the regeneration membrane. As a result, the regenerated membrane easily sloshes and causes the bone meal covered by it to move and cannot form bone, resulting in failure of bone regeneration.

Therefore, one of the objectives of the present invention is to provide a supporting device that can overcome at least one of the disadvantages of the prior art.

Therefore, the support device of the present invention is suitable for supporting a biofilm.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.

Referring to FIG. 1, the first embodiment of the supporting device 100 of the present invention includes a supporting bar 1 and a clamping piece 2.

1 and 2, the support bar 1 is made by, for example, casting or CNC machining. The material of the support bar 1 is titanium as an example. The support bar 1 is elongated and extends along a length direction D1. The support bar 1 includes a middle section 11 and two end sections 12. The middle section 11 has a sheet shape and extends along the length direction D1. The middle section 11 has two first end surfaces 110 and two side surfaces 111. The first end surfaces 110 are spaced apart along the length direction D1. The side surfaces 111 are spaced apart along a thickness direction D2 perpendicular to the length direction D1 and connected to the opposite sides of the first end surfaces 110. The end sections 12 are respectively formed at opposite ends of the middle section 11 and are spaced apart along a width direction D3, which is perpendicular to the length direction D1 and the thickness direction D2. Each of the end sections 12 is cylindrical and has two second end surfaces 120 and an arc-shaped surface 121. The second end surfaces 120 are spaced apart along the length direction D1 and connected to the first end surfaces 110 respectively. The arc-shaped surface 121 extends along the length direction D1 and is connected between the second end surfaces 120. The arc-shaped surface 121 protrudes from the side surfaces 111 and is connected between the side surfaces 111 to support For example, a biofilm 4 used as a regenerated film (as shown in FIG. 6).

A width W of the support bar 1 along the width direction D3 is less than or equal to 3 millimeters (mm), and a thickness T of the support bar 1 along the thickness direction D2 is greater than or equal to 1 mm. In the first embodiment, the width W is 3 mm as an example, and the thickness T is 1 mm as an example. Since the thickness T of the support bar 1 is very thin, the support bar 1 has flexibility. More specifically, because the arc-shaped surface 121 protrudes from the side surfaces 111, a first thickness T1 of the middle section 11 along the thickness direction D2 is smaller than that of each end portion 12 along the thickness direction D2. Take a second thickness T2. In the first embodiment, the first thickness T1 is, for example, 0.5 mm, the second thickness T2 is the thickness T, and the second thickness T2 is 1 mm. A distance D of the arc-shaped surface 121 of each end section 12 protruding from the corresponding side surface 111 is 0.25 mm. Thereby, the support bar 1 can be easily bent and deformed into a desired specific shape, and at the same time, sufficient support strength can be maintained.

The material of the clamping piece 2 is titanium metal as an example. The clamping piece 2 is detachably clamped to the supporting bar 1 and used to hold the biofilm 4 on the supporting bar 1. The clamping piece 2 includes a main piece body 21 and two elastic pieces 22. The main sheet body 21 matches the shape of the corresponding side surface 111 of the middle section 11, and the main sheet body 21 is used for contacting and pressing the biofilm 4 and has an outer side surface 211 and an inner side surface 212. The elastic sheets 22 are respectively connected to the opposite ends of the main sheet 21 in a curved manner and are spaced apart along the width direction D3. The elastic sheets 22 are respectively used to clamp the circular arcs of the end sections 12 Surface 121. Each of the elastic sheets 22 is bent and extended from one end of the main sheet 21 outward and away from the main sheet 21 for a certain distance and protrudes out of the outer side surface 211, and then bends inward for a certain distance and protrudes. The inner side surface 212 allows each of the elastic sheets 22 to form an arc structure whose shape matches the corresponding arc-shaped surface 121. Each of the elastic sheets 22 is used for contacting and pressing the biofilm 4 and has a free end 221. The free ends 221 of the elastic sheets 22 along the width direction D3 take a distance S smaller than the width W. Thereby, when each elastic piece 22 is assembled to the corresponding end section 12, the free end 221 can contact the arc-shaped surface 121 and slide thereon, so as to promote each elastic piece 22 relative to the main piece. The body 21 is bent and deformed to be buckled with the corresponding end section 12.

The method of using the supporting device 100 will be described in detail below:

Referring to FIG. 3, the supporting device 100 (as shown in FIG. 1) is suitable for being installed in a bone defect structure 3 of a human body and used to support the biofilm 4 (as shown in FIG. 6). The bone defect structure 3 is an alveolar bone as an example. 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.

Referring to FIG. 4, FIG. 4 is a step-by-step flow chart of the method of using the supporting device 100 of the first embodiment. The method of use includes the following steps: step S1 of providing the supporting device, step S2 of installing the support bar, step S2 of covering the biofilm S3, and step S4 of holding the biofilm.

Referring to FIGS. 1 and 4, in the step S1 of providing the supporting device, the supporting device 100 includes the supporting bar 1 and the clamping piece 2.

Referring to Figures 3, 4 and 5, in the step S2 of installing the support bar, the user needs to first use a tool such as pliers to make a hole in the middle section 11 of the support bar 1 to make a hole in the middle section 11 of the support bar 1. The middle section 11 forms two perforations 112 extending between the side surfaces 111. The perforations 112 are spaced apart along the length direction D1 and are respectively adjacent to the first end surfaces 110 of the middle section 11 (as shown in FIG. 1 ).

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 the first embodiment, the specific position refers to a position corresponding to the corner portion 341. For example, the arc-shaped surfaces 121 of the end sections 12 of the support bar 1 abut the cheek side 32 adjacent to the top end 31, so that the support bar 1 corresponds to the corner portion 341 and crosses the Corner 341. Subsequently, two bone nails 5 are respectively inserted through the perforations 112 and screwed on the buccal side 32 to lock the support bar 1 on 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 depending on requirements. One of the methods is to abut the arc-shaped surfaces 121 of the support bar 1 against the top end 31 adjacent to the cheek side 32. , The support bar 1 is locked to the top end 31 of the bone defect structure 3 through the bone nails 5. Another way is to abut the arc-shaped surfaces 121 of the support bar 1 against the junction of the top end 31 and the buccal side 32, and lock the support bar 1 to the bone defect structure through the bone nails 5. The junction of the top end 31 and the buccal side 32 of 3. Thereby, the support bar 1 can also be made to correspond to the corner portion 341 and span the corner portion 341.

The support bar 1 is designed in such a way that the end sections 12 are respectively formed at the opposite ends of the middle section 11, so that the support bar 1 is at an angular position as shown in FIG. An angular position where the center line extending in the longitudinal direction D1 is rotated by 180 degrees can be locked to the bone defect structure 3, thereby improving the convenience of assembly.

4, 6 and 7, in the biofilm covering step S3, the biofilm 4 is first covered on the lingual side 33 of the bone defect structure 3, and the biofilm is passed through sutures (not shown). The membrane 4 is fixed to the lingual side 33. Next, fill the bone meal 6 into the recessed space 34. After the filling is completed, cover the top 31, the recessed space 34, the support strip 1 and the buccal side 32 with the biofilm 4 so that the biological film 4 covers the recessed space 34 and the support strip 1. At this time, The supporting strip 1 supports the biofilm 4 through the arc-shaped surfaces 121.

Referring to FIG. 2, FIG. 4, FIG. 8 and FIG. 9, in the biofilm holding step S4, a lateral pressure F is applied to the clamping piece 2 to move it laterally toward the support bar 1. Since the distance S between the free ends 221 of the elastic sheet bodies 22 is smaller than the width W, the free end 221 of each elastic sheet body 22 will contact during the lateral movement of the clamping sheet 2 The biofilm 4 presses it against the corresponding arc-shaped surface 121. Subsequently, the free end 221 of each elastic piece 22 will slide along the corresponding arc-shaped surface 121 to promote the bending and deformation of each elastic piece 22 relative to the main piece 21 and accumulate the reset elastic force. Since each of the elastic sheets 22 partially protrudes from the outer side surface 211 of the main sheet 21, each elastic sheet 22 will drive the main sheet 21 in the process of bending and deforming relative to the main sheet 21. Slightly deformed inwardly. When the free end 221 of each elastic piece 22 passes over the end of the corresponding arc-shaped surface 121 and separates from it, each elastic piece 22 will automatically snap onto the corresponding one by the accumulated reset elastic force. The end section 12 thereby enables the elastic sheets 22 to clamp the biofilm 4 and the arc-shaped surfaces 121 to hold the biofilm 4 on the support bar 1. The main sheet body 21 is slightly recessed and deformed inwardly, so that the inner side surface 212 of the main sheet body 21 can press the corresponding part of the biofilm 4 so that it can closely adhere to the corresponding portion of the middle section 11 Side 111. By matching the shape of each elastic sheet 22 with the corresponding arc-shaped surface 121, each elastic sheet 22 can be pressed against the corresponding part of the biofilm 4 so that it can be closely adhered to the corresponding The arc-shaped surface 121. Thereby, the supporting strip 1 and the clamping piece 2 can have a larger contact area with the biofilm 4 to improve the stability of holding the biofilm 4.

By the design of the arc-shaped surface 121 of each end section 12 protruding from the side surfaces 111 of the middle section 11, the support bar 1 faces the cheek side 32 with any one of the side surfaces 111 and is locked to the When the buccal side 32, the free end 221 of each elastic sheet 22 can press the biofilm 4 against the corresponding arc-shaped surface 121 and can slide along the corresponding arc-shaped surface 121, so that Each elastic piece 22 can be smoothly buckled to the corresponding end section 12. Thereby, the clamping piece 2 will not be affected by the assembling direction of the support bar 1, so as to improve the convenience of assembly of the clamping piece 2.

It should be noted that in other implementations of the first embodiment, each of the elastic sheets 22 can also be bent inwardly by one end of the main sheet 21 without protruding from the outer side surface 212 of the main sheet 21 , So that after the clamping piece 2 holds the biofilm 4 on the support bar 1, the biofilm 4 is separated from the corresponding side surface 111 by a certain distance.

After the clamping piece 2 holds the biofilm 4 on the supporting strip 1, the skin flap (not shown) completely covers the biofilm 4 and the supporting device 100, and then the skin flap is sutured. Thereby, after the gum is healed, the biofilm 4 and the supporting device 100 can be completely covered.

Referring to Figures 2, 8 and 9, in the first embodiment, the support strip 1 supports the biofilm 4 by the smooth arc-shaped surfaces 121, which can prevent the gum from being arbitrary during the healing period. One of the end sections 12 is pierced to prevent the supporting strip 1 from exposing the bone area and causing the operation to fail. In addition, since the support bar 1 is only formed with perforations 112 (as shown in FIG. 3) for the bone nails 5 (as shown in FIG. 5) to pass through only in the middle section 11, there are no other holes, so It can prevent the soft tissue from growing into the supporting strip 1 during the healing period and sticking to it. Thereby, when the gum is healed, a slot is cut in the gum, the clamping piece 2 is first detached from the support strip 1, and then the bone nails 5 are unscrewed, and the bone nails 5 can be easily and quickly The support bar 1 is taken out. On the other hand, with the design of the clamping piece 2, the biofilm 4 can be held on the support bar 1 very conveniently and quickly, so as to prevent the biofilm 4 from shaking relative to the support bar 1. Furthermore, since the support bar 1 is elongated and can span the corner portion 341 (as shown in FIG. 3), the user can stably support the creature by using a single set of the support device 100 The effect of the membrane 4 can improve the convenience of assembly and use and postoperative disassembly.

The structure of the support bar 1 of the support device 100 of the first embodiment can have the following different aspects as required:

One aspect is that the arc-shaped surfaces 121 of the end sections 12 can be designed to protrude only one of the side surfaces 111 of the middle section 11, and the side surfaces 111 can face when the support bar 1 is assembled and used. The clamping piece 2.

Another aspect is that the number of the end section 12 of the support bar 1 is one, and the arc-shaped surface 121 of the end section 12 can be designed to protrude from the side surfaces 111 of the middle section 11 at the same time. 12 can face upward when the support bar 1 is assembled and used.

Another aspect is: the number of the end section 12 of the support bar 1 is one, the arc-shaped surface 121 of the end section 12 can be designed to protrude only from one of the side surfaces 111 of the middle section 11, and the end The section 12 can face upward when the support bar 1 is assembled and used, and the side surface 111 can face the clamping piece 2 when the support bar 1 is assembled and used.

In particular, in another implementation aspect of the first embodiment, the supporting device 100 may also only have the supporting bar 1. In the step S4 of fixing the biofilm under this embodiment, the biofilm 4 can be fixed on the buccal side 32 through sutures (not shown), and the effect of fixing the biofilm 4 can also be achieved.

10 and 11, the second embodiment of the supporting device 100 of the present invention has the same overall structure as the first embodiment, but the difference lies in the method of using the supporting device 100.

In the second embodiment, the recessed space 34 of the bone defect structure 3 is formed by the top end 31 recessed downward. In the step S2 of installing the support bar (as shown in FIG. 4), first bend the support bar 1 into an inverted U shape, so that the support bar 1 forms a top support portion 13, and two are respectively located at the top support portion 13 The side support 14 at the opposite end. The top support portion 13 is placed above the recessed space 34 and across the recessed space 34, and the side support portions 14 abut against the buccal side 32 and the lingual side 33, respectively. Subsequently, the side supporting portions 14 are locked to the buccal side 32 and the lingual side 33 through the bone nails 5 respectively, so that the supporting strip 1 is fixed to the bone defect structure 3. Afterwards, the biofilm 4 is covered on the support strip 1, the buccal side 32 and the lingual side 33, and then the biofilm 4 is held on the support strip 1 through the clamping sheet 2 (as shown in FIG. 9). The top support portion 13.

Since the side support portions 14 of the support bar 1 are locked to the buccal side 32 and the lingual side 33 through the bone nails 5, respectively, the support bar 1 can be firmly fixed to the bone defect structure 3, which is not easy Shaking. In addition, by bending the support strip 1 into an inverted U shape, the support strip 1 can support the biofilm 4 through the top support portion 13 and the side support portions 14 at the same time, because the support strip 1 supports the biofilm 4 The area of 4 is large, and therefore, the biofilm 4 can be stably supported. Compared with the long bone nail support method in the prior art, it can more accurately control the shape of the bone meal 6 after it has grown into bone.

Referring to FIGS. 12 and 13, the third embodiment of the supporting device 100 of the present invention has the same overall structure and method of use as the second embodiment, but the difference lies in the number of the supporting device 100.

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 very wide. Big. In the step S1 of providing a supporting device (as shown in FIG. 4 ), the number of the supporting device 100 is multiple, and the number of the supporting device 100 used is determined according to the size of the area of the recessed space 34. In the step S2 of installing the supporting bars (as shown in FIG. 4 ), the supporting bars 1 are bent into an inverted U shape, and the supporting bars 1 are arranged on the bone defect structure 3 at intervals. Subsequently, the supporting strips 1 are locked on the bone defect structure 3. Since the side support portions 14 of each support bar 1 are respectively locked to the buccal side 32 and the lingual side 33 through the bone nails 5, each support bar 1 can be firmly fixed to the bone defect structure 3 Not easy to shake. In addition, by bending the supporting strips 1 into an inverted U shape and supporting the biofilm 4 at the same time, the biofilm 4 can be stably supported. Compared with the long bone nail support method in the prior art, it can more accurately control the shape of the bone meal 6 after it has grown into bone.

Referring to FIG. 14, the fourth embodiment of the supporting device 100 of the present invention has the same overall structure and usage method as that of the first embodiment, except for the structure of the supporting bar 1.

In the fourth embodiment, each end section 12 of the support bar 1 is formed with a through hole 122 extending between the second end surfaces 120 along the length direction D1 (as shown in FIG. 1 ). Thereby, the user can conveniently clamp each of the end sections 12 with an auxiliary tool, so that each of the end sections 12 can conform to the bone defect structure 3 with large undulations on the surface (as shown in FIG. 3).

Referring to FIG. 15, the fifth embodiment of the supporting device 100 of the present invention has the same overall structure and usage method as the first embodiment, but the difference lies in the structure of the supporting bar 1.

In the fifth embodiment, the middle section 11 and the end sections 12 of the support bar 1 jointly define a line extending along the length direction D1 (as shown in FIG. 1) on the first and second end surfaces 110 , 120 between the through hole 15. Thereby, the user can conveniently clamp the middle section 11 and the end sections 12 with an auxiliary tool, so that the support strip 1 can conform to the bone defect structure 3 with large undulations on the surface (as shown in FIG. 3). ).

Referring to FIG. 16, the overall structure and use method of the sixth embodiment of the supporting device 100 of the present invention are roughly the same as those of the first embodiment, except for the structure of the supporting bar 1.

In the sixth embodiment, the user can use a cutting tool to cut the opposite ends of each end section 12 to an appropriate length, so that the first end surfaces 110 of the middle section 11 protrude from each other. The second end surfaces 120 at the opposite ends of the end section 12 have an appropriate distance. Thereby, the middle section 11 can be adhered to the bone defect structure 3 (as shown in FIG. 3) with large surface undulations through the parts protruding from the end sections 12 corresponding to the side surface 111.

Referring to FIG. 7, the seventh embodiment of the supporting device 100 of the present invention has the overall structure roughly the same as that of the first embodiment, but the difference lies in the method of use.

After the bone powder 6 of the first embodiment grows into bone in the recessed space 34, the prosthesis of dental implants will be carried out in the follow-up. After long-term use, the implant will almost face the condition of bone resorption at the buccal 32. This is due to the lack of periodontal ligaments like natural teeth around the implant, and bone hyperplasia cannot be stimulated by the body receptors in the ligament. . The bone resorption at the buccal side 32 will cause many problems, such as food residues that are not easy to clean, gum inflammation, and even peri-implant inflammation. Therefore, in the seventh embodiment, after the gum is healed and a groove is cut out on the gum, only the clamping piece 2 (as shown in FIG. 9) is taken out, and the support strip 1 is left in The specific location is not taken out, thereby reducing the bone resorption at the buccal side 32.

D1 phase interval. The through holes 113 allow the soft tissues to grow in to improve the stability of the connection, so that the bone can be firmly combined with the support bar 1 after covering it. In another implementation aspect of the seventh embodiment, the first end surfaces 110, the side surfaces 111, the second end surfaces 120, and the arc-shaped surfaces 121 of the support bar 1 can also be sandblasted, for example. Or surface treatment methods such as acid etching increase the surface roughness to improve the adhesion of the bone, so that the bone can be firmly combined with the support strip 1 after covering it.

In summary, in the supporting device 100 of each embodiment, the supporting strip 1 supports the biofilm 4 by the smooth arc-shaped surfaces 121, which can prevent the gum from being damaged by any one of the ends during the healing period. Segment 12 was pierced to prevent exposing the bony area and causing the operation to fail. In addition, with the design of the clamping piece 2, the biofilm 4 can be held on the support bar 1 very conveniently and quickly, so as to prevent the biofilm 4 from shaking relative to the support bar 1. In the first embodiment, since the support bar 1 is elongated and can span the corner portion 341 (as shown in FIG. 3), the user can achieve by using a single set of the support device 100 The effect of stably supporting the biofilm 4 can improve the convenience of assembly and use and postoperative disassembly. In the second and third embodiments, the support bar 1 can be bent into an inverted U-shape and support the biofilm 4, which has the effect of stably supporting the biofilm 4. In the first to sixth embodiments, since the support strip 1 is only formed in the middle section 11 with perforations 112 for the bone nails 5 to pass through, and there are no other holes, it can prevent the gum from being During the healing period, the soft tissue grows into the support strip 1 and adheres to it.
