Description

Support device and using method thereof

Technical Field

The present invention relates to a support device, and more particularly, to a support device for supporting a biological membrane and a method for using the same.

Background

In Bone Regeneration prior to dental implant, such as Guided Bone Regeneration (GBR), a regenerative membrane is used to cover the defect area to define the volume and type of Bone growth required. The regenerated membranes are mainly of two types, one is absorbable membrane which can be absorbed by human body, and the other is non-absorbable membrane which can not be absorbed by human body and needs to be taken out by secondary operation. Because the absorbable membranes are made of softer materials, when a large range of defect areas are met, the absorbable membranes are supported by a supporting structure to support the required bone supplementing space. The common methods for supporting the regenerated membrane are mainly: a titanium metal net supporting mode and a long bone nail supporting mode.

The titanium metal mesh supporting mode has the following defects:

because the titanium metal net is covered with a plurality of through holes, the titanium metal net can be adhered to the titanium metal net because soft tissues grow into the holes when the titanium metal net is taken out after bone supplementing is finished, so that the titanium metal net is not easy to take out.

In addition, because the holes are distributed on the titanium metal net, the titanium metal net is in a non-smooth state with unevenness, and the hole edges of the holes defined by the titanium metal net are sharp, so that when the titanium metal net is bent into a specific shape, the bending corner parts of the titanium metal net are relatively rough. This may cause the thinner region of the teethridge to be punctured by the bent corner of the titanium mesh during the healing period of the teethridge after surgery, so that the bent corner exposes the teethridge, which may lead to bone loss and tissue infection, which is the main reason for the most frequent failure of the aforementioned surgery.

Furthermore, some of the titanium meshes are designed to have a fixed shape and size, and are matched with a locking piece to form a supporting device together. If the range of the defect area is too large, a plurality of groups of the supporting devices are used at the same time, which results in more complex and inconvenient use.

The long bone nail supporting mode has the following defects:

in the supporting mode, a plurality of long bone nails are firstly locked on an alveolar bone, and then the regeneration membrane is covered on a screw head of each long bone nail, so that the regeneration membrane is supported by the long bone nails. Because the alveolar bone is often shrunk, the length of the alveolar bone in which the long bone nails can be locked is limited, and therefore, when the part of each long bone nail, which is exposed out of the alveolar bone, is much longer than the part of each long bone nail, which is locked in the alveolar bone, each long bone nail is easily shaken under the influence of external force. In addition, the screw head of each long bone nail has a small area for supporting the regeneration membrane, resulting in poor stability of each long bone nail for supporting the regeneration membrane. Thus, the regeneration membrane is easily shaken and causes the bone powder coated by the regeneration membrane to move and fail to form bone, thereby causing the failure of bone regeneration.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Before the present invention is described in detail, it should be noted that in the following description, like elements are represented by like reference numerals.

Referring to fig. 1, a supporting device 100 according to a first embodiment of the present invention includes a supporting strip 1 and a holding strip 2.

Referring to fig. 1 and 2, the support strip 1 is manufactured by, for example, casting or CNC machining, and the material of the support strip 1 is titanium. The supporting strip 1 is elongated and extends along a length direction D1, and the supporting strip 1 includes a middle section 11 and two end sections 12. The middle section 11 is sheet-shaped and extends along the length direction D1, and the middle section 11 has two first end faces 110 and two side faces 111. The first end surfaces 110 are spaced apart along the length direction D1. The side surfaces 111 are spaced apart from each other along a thickness direction D2 perpendicular to the length direction D1 and connected to opposite sides of the first end surface 110. The end sections 12 are formed at opposite ends of the middle section 11 and spaced apart along a width direction D3, the width direction D3 being perpendicular to the length direction D1 and the thickness direction D2. Each end segment 12 is cylindrical and has two second end faces 120 and an arcuate 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 faces 120, and the arc-shaped surface 121 protrudes out of the side faces 111 and is connected between the side faces 111 for supporting a biofilm 4 (as shown in fig. 6) used as a regeneration membrane, for example.

A width W that support bar 1 was taken along width direction D3 is less than or equal to 3 millimeters (mm), a thickness T that support bar 1 was taken along thickness direction D2 is greater than or equal to 1 millimeter. In the first embodiment, the width W is exemplified by 3 mm, and the thickness T is exemplified by 1 mm. Since the thickness T of the support strip 1 is very thin, the support strip 1 has flexibility. More specifically, since the circular-arc-shaped surface 121 protrudes beyond the side surface 111, the first thickness T1 of the middle section 11 taken in the thickness direction D2 is smaller than the second thickness T2 of each end section 12 taken in the thickness direction D2. 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. The circular-arc-shaped surface 121 of each end segment 12 projects out of the corresponding side 111 by a distance D of 0.25 mm. Thereby, the support strip 1 can be easily bent and deformed into a desired specific shape while maintaining sufficient support strength.

The material of the clamping piece 2 is titanium metal as an example. The clamping sheets 2 are detachably clamped on the supporting bar 1 and used for fixing the biological membrane 4 on the supporting bar 1. The holding piece 2 includes a main piece 21 and two elastic pieces 22. The main sheet body 21 is matched with the corresponding side surface 111 of the middle section 11 in shape, and the main sheet body 21 is used for contacting and pressing the biological membrane 4 and has an outer side surface 211 and an inner side surface 212. The elastic blades 22 are respectively connected to opposite ends of the main blade 21 in a curved manner and spaced apart from each other in the width direction D3, and the elastic blades 22 are respectively configured to be clamped on the circular arc-shaped surfaces 121 of the end segments 12. Each elastic sheet 22 extends from one end of the main sheet 21 to the outside and bends to a distance away from the main sheet 21 and protrudes out of the outer side 211, and then extends to the inside and bends to a distance and protrudes out of the inner side 212, so that each elastic sheet 22 forms an arc-shaped structure with a shape matched with the corresponding arc-shaped surface 121. Each of the elastic sheet bodies 22 is configured to contact and press against the biological membrane 4 and has a free end 221, and a distance S between the free ends 221 of the elastic sheet bodies 22 along the width direction D3 is smaller than the width W. Therefore, when each elastic sheet body 22 is assembled to the corresponding end segment 12, the free end 221 can contact and slide on the arc-shaped surface 121, so as to cause each elastic sheet body 22 to bend and deform relative to the main sheet body 21 and further buckle to the corresponding end segment 12.

The following is a detailed description of the method of using the support device 100:

referring to fig. 3, the support device 100 (shown in fig. 1) is adapted to be mounted to a bone defect structure 3 of a human body and to support the biofilm 4 (shown in fig. 6). The bone defect structure 3 is exemplified by an alveolar bone, and the bone defect structure 3 has an apex 31, a buccal side 32 and a lingual side 33. The apical end 31 and the buccal side 32 of the bone defect structure 3 are recessed to form a recessed space 34, the recessed space 34 having a corner 341 between the apical end 31 and the buccal side 32.

Referring to FIG. 4, FIG. 4 is a flow chart illustrating a method of using the supporting device 100 according to the first embodiment, the method includes providing the supporting device S1, installing the supporting strip S2, covering the bio-film S3, and holding the bio-film S4.

Referring to fig. 1 and 4, in the step S1 of providing the supporting device, the supporting device 100 includes the supporting strip 1 and the holding strip 2.

Referring to fig. 3, 4 and 5, in the step S2 of mounting the brace bar, a user first needs to make a hole in the middle section 11 of the brace bar 1 at a proper position by a tool such as a pair of pliers to form two through holes 112 extending between the side surfaces 111 in the middle section 11, wherein the through holes 112 are spaced apart along the length direction D1 and are respectively adjacent to the first end surface 110 of the middle section 11 (as shown in fig. 1).

Next, the supporting bar 1 is placed on the bone defect structure 3 at a specific position corresponding to the depressed space 34. In the first embodiment, the specific position refers to a position corresponding to the corner 341. For example, the rounded surface 121 of the end section 12 of the brace bar 1 is pressed against the buccal side 32 adjacent to the apex 31, so that the brace bar 1 corresponds to the corner 341 and spans the corner 341. Then, two bone screws 5 are respectively arranged through the through holes 112 and screwed on the buccal side 32, so as to lock the supporting bar 1 on the buccal side 32 of the bone defect structure 3. It should be noted that the supporting bar 1 can be mounted by two ways as required, one way is to abut the arc surface 121 of the supporting bar 1 against the top end 31 adjacent to the buccal side 32, and the supporting bar 1 is locked to the top end 31 of the bone defect structure 3 by the bone nails 5. Alternatively, the arc-shaped surface 121 of the supporting bar 1 is abutted against the junction of the top end 31 and the buccal side 32, and the supporting bar 1 is locked at the junction of the top end 31 and the buccal side 32 of the bone defect structure 3 through the bone nails 5. Thereby, the supporting strip 1 can be made to correspond to the corner portions 341 and cross over the corner portions 341.

The design of the support bar 1 with the end sections 12 formed at the opposite ends of the middle section 11 enables the support bar 1 to be locked to the bone defect structure 3 at the angular position shown in fig. 5 or at an angular position rotated 180 degrees around a center line of the middle section 11 extending along the length direction D1, thereby improving the convenience of assembly.

Referring to fig. 4, 6 and 7, in the step S3 of covering the biological membrane, the biological membrane 4 is firstly 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 a suture (not shown). Then, bone meal 6 is filled into the depressed space 34. After the filling process is completed, the biofilm 4 is covered on the top end 31, the concave space 34, the supporting strip 1 and the buccal side 32, so that the biofilm 4 shields the concave space 34 and the supporting strip 1, and at this time, the supporting strip 1 supports the biofilm 4 through the arc-shaped surface 121.

Referring to fig. 2, 4, 8 and 9, in the step S4 of holding the biofilm, a lateral pressure F is applied to the holding pieces 2 to move the holding pieces laterally toward the supporting bars 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 contacts and presses the biofilm 4 against the corresponding circular arc surface 121 during the transverse movement of the clamping piece 2. Then, the free end 221 of each elastic blade 22 slides along the corresponding circular arc surface 121, so as to cause each elastic blade 22 to bend and deform relative to the main blade 21 and accumulate a return elastic force. Because each elastic sheet body 22 partially protrudes out of the outer side 211 of the main sheet body 21, each elastic sheet body 22 drives the main sheet body 21 to slightly deform inwardly in a concave manner in the process of bending deformation relative to the main sheet body 21. When the free end 221 of each elastic sheet body 22 passes over and separates from the corresponding end portion of the circular arc-shaped surface 121, each elastic sheet body 22 automatically snaps into the corresponding end section 12 by the accumulated restoring elastic force, thereby enabling the elastic sheet bodies 22 to clamp the biofilm 4 and the circular arc-shaped surface 121 to hold the biofilm 4 on the supporting strip 1. The main sheet body 21 is slightly inwardly concave and deformed, so that the inner side 212 of the main sheet body 21 can press the corresponding part of the biological membrane 4 to be tightly attached to the corresponding side 111 of the middle section 11. By matching the shape of each elastic sheet body 22 with the corresponding circular arc-shaped surface 121, each elastic sheet body 22 can press the corresponding part of the biological membrane 4 to be tightly attached to the corresponding circular arc-shaped surface 121. Therefore, the supporting strips 1 and the clamping strips 2 have larger contact areas with the biological membranes 4 so as to improve the stability of holding the biological membranes 4.

By the design manner that the arc-shaped surface 121 of each end segment 12 protrudes out of the side surface 111 of the middle segment 11, when any one of the side surfaces 111 of the support strip 1 faces the buccal side 32 and is locked on 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 sheet 22 can be smoothly fastened to the corresponding end segment 12. Therefore, the clamping pieces 2 are not affected by the assembling directionality of the supporting strips 1, and the assembling convenience of the clamping pieces 2 is improved.

It should be noted that, in other embodiments of the first embodiment, each elastic sheet 22 may also extend from one end of the main sheet 21 to be bent inward without protruding out of the outer side 211 of the main sheet 21, so that after the holding sheet 2 holds the biofilm 4 on the supporting strip 1, the biofilm 4 is spaced from the corresponding side 111 by a certain distance.

After the holding piece 2 holds the biofilm 4 on the supporting strip 1, a flap (not shown) is completely covered on the biofilm 4 and the supporting device 100, and then the flap is sutured. Thereby, the dental pulp can entirely cover the biofilm 4 and the supporting device 100 after healing.

Referring to fig. 2, 8 and 9, in the first embodiment, the supporting strip 1 supports the biofilm 4 by the smooth arc-shaped surface 121, which can prevent the meat from being punctured by any one of the end sections 12 during the healing period, so as to prevent the supporting strip 1 from exposing the bone-supplementing area and causing the operation failure. In addition, since the supporting strip 1 is formed with the through holes 112 (shown in fig. 3) for the bone screws 5 (shown in fig. 5) to pass through respectively only in the middle section 11 without other holes, the soft tissue of the dental pulp can be prevented from growing into the supporting strip 1 and adhering thereto during the healing period. Therefore, after the dental pulp is healed, a groove is cut in the dental pulp, the clamping piece 2 is firstly detached from the supporting strip 1, and then the bone nail 5 is screwed down, so that the supporting strip 1 can be conveniently and quickly taken out. On the other hand, by the design of the clamping sheet 2, the biofilm 4 can be very conveniently and rapidly fixed on the supporting strip 1, so as to prevent the biofilm 4 from shaking relative to the supporting strip 1. Moreover, since the supporting strip 1 is elongated and can cross over the corner 341 (as shown in fig. 3), the user can stably support the biological membrane 4 by using a single set of the supporting device 100, thereby improving the convenience of assembly, use and post-operation disassembly.

The structure of the supporting bar 1 of the supporting device 100 of the first embodiment can have the following different aspects according to requirements:

one such aspect is: the circular-arc-shaped surface 121 of the end section 12 can be designed to project out of only one of the side faces 111 of the intermediate section 11, which side face 111 can face the retaining strip 2 when the support strip 1 is assembled for use.

Another aspect is: the end section 12 of the support strip 1 is one in number, the circular arc-shaped surface 121 of the end section 12 can be designed to project out of the side 111 of the middle section 11 at the same time, and the end section 12 can be oriented upwards when the support strip 1 is assembled for use.

Yet another aspect is: the support strip 1 has one end section 12, the circular arc surface 121 of the end section 12 can be designed to project out of only one side 111 of the middle section 11, the end section 12 can face upward when the support strip 1 is assembled for use, and the one side 111 can face the clamping piece 2 when the support strip 1 is assembled for use.

In particular, in another implementation of the first embodiment, the supporting device 100 may also have only the supporting strip 1. In the step S4 of holding the biofilm in this embodiment, the biofilm 4 can be fixed on the buccal side 32 by a suture (not shown), and the effect of holding the biofilm 4 can also be achieved.

Referring to fig. 10 and 11, the overall structure of the second embodiment of the supporting device 100 of the present invention is the same as that of the first embodiment, except for the use method of the supporting device 100.

In this second embodiment, the concave space 34 of the bone defect structure 3 is formed by the downward concavity of the top end 31. In the step S2 (shown in fig. 4), the supporting strip 1 is bent into an inverted U shape, so that the supporting strip 1 forms a top supporting portion 13 and two side supporting portions 14 respectively located at opposite ends of the top supporting portion 13. The top support 13 is placed over the recessed space 34 and spans the recessed space 34, and the side supports 14 abut 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 by the bone screws 5, respectively, so that the supporting bar 1 is fixed to the bone defect structure 3. Thereafter, the biofilm 4 is covered on the supporting strip 1, the buccal side 32 and the lingual side 33, and then the biofilm 4 is held on the top supporting portion 13 of the supporting strip 1 by the holding sheet 2 (as shown in fig. 9).

Since the side supporting portions 14 of the supporting bar 1 are respectively locked to the buccal side 32 and the lingual side 33 by the bone screws 5, the supporting bar 1 can be stably fixed to the bone defect structure 3 without shaking. In addition, by bending the supporting strip 1 into an inverted U shape, the supporting strip 1 can simultaneously support the biofilm 4 through the top supporting part 13 and the side supporting part 14, and the supporting strip 1 has a large area for supporting the biofilm 4, so that the effect of stably supporting the biofilm 4 can be achieved. Compared with the long bone nail supporting mode in the prior art, the shape of the bone powder 6 after growing into bone can be controlled more accurately.

Referring to fig. 12 and 13, the overall structure and the using method of the third embodiment of the supporting device 100 of the present invention are the same as those of the second embodiment, except for the number of the supporting devices 100.

In the third embodiment, the concave space 34 of the bone defect structure 3 is formed between the buccal side 32 and the lingual side 33 by being depressed downward from the tip 31, and the area of the concave space 34 is wide. In the step S1 (shown in fig. 4), the number of the supporting devices 100 is plural, and the number of the supporting devices 100 is determined according to the size of the area of the recessed space 34. In the supporting bar mounting step S2 (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 support bar 1 is locked to the bone defect structure 3. Since the lateral supporting portions 14 of the supporting bars 1 are respectively locked to the buccal side 32 and the lingual side 33 by the bone screws 5, the supporting bars 1 can be stably fixed to the bone defect structure 3 without shaking. In addition, the supporting strips 1 are respectively bent into an inverted U shape and simultaneously support the biological membrane 4, so that the effect of stably supporting the biological membrane 4 can be achieved. Compared with the long bone nail supporting mode in the prior art, the shape of the bone powder 6 after growing into bone can be controlled more accurately.

Referring to fig. 14, the overall structure and the using method of the fourth embodiment of the supporting device 100 of the present invention are substantially the same as those of the first embodiment, except for the structure of the supporting strip 1.

In the fourth embodiment, each end section 12 of the support strip 1 is formed with a through hole 122 extending between the second end faces 120 along the length direction D1 (shown in fig. 1). Thereby, the user can easily pinch each end segment 12 flat by means of an auxiliary tool, so that each end segment 12 can be conformed to the bone defect structure 3 (as shown in fig. 3) with large surface relief.

Referring to fig. 15, the overall structure and usage of the fifth embodiment of the supporting device 100 of the present invention are substantially the same as the first embodiment, except for the structure of the supporting strip 1.

In the fifth embodiment, the middle section 11 and the end section 12 of the supporting bar 1 together define a through hole 15 extending between the first end surface 110 and the second end surface 120 along the length direction D1 (shown in fig. 1). Thereby, the user can easily clamp the middle section 11 and the end section 12 by an auxiliary tool so that the support bar 1 can be attached to the bone defect structure 3 with large surface undulation (as shown in fig. 3).

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

In the sixth embodiment, the user can cut the opposite ends of each end segment 12 by a cutting tool to a proper length so that the first end surface 110 of the middle segment 11 protrudes a proper distance beyond the second end surfaces 120 of the opposite ends of each end segment 12. Thereby, the middle section 11 can be made to conform to the bone defect structure 3 with large surface relief through the portions corresponding to the side surfaces 111 protruding out of each end section 12 (as shown in fig. 3).

Referring to fig. 17, the overall structure of the seventh embodiment of the supporting device 100 of the present invention is substantially the same as that of the first embodiment, except for the use method.

After completion of the bone supplementing operation in which the bone powder 6 of the first embodiment grows into bone in the recessed space 34, the dental implant prosthesis is performed subsequently. The implant is almost always exposed to bone absorption at the buccal side 32 after long-term use, since there is a lack of periodontal ligaments like natural teeth around the implant, which cannot be stimulated to bone hyperplasia by the proprioceptors in the ligaments. The bone absorption at the buccal side 32 causes many problems such as food residue, difficulty in cleaning, inflammation of the gums, and even peri-implantitis. Therefore, in the seventh embodiment, after the teethridge is healed and a groove is cut in the teethridge, only the holding pieces 2 (as shown in fig. 9) are removed, and the supporting pieces 1 are left at the specific position without being removed, whereby the bone absorption condition at the buccal side 32 can be reduced.

Referring to fig. 17, in another implementation of the seventh embodiment, in the step S2 (shown in fig. 4) of mounting the supporting strip, the user further punches a hole on the middle section 11 of the supporting strip 1 at a proper position by the tool, such as a pair of pliers, to form a plurality of through holes 113 extending between the side surfaces 111 and located between the through holes 112 in the middle section 11, wherein the through holes 113 are spaced apart along the length direction D1. The through holes 113 allow soft tissue to grow therein to improve the stability of the combination, so that the supporting bars 1 can be firmly combined with the bone after being covered by the bone. In another aspect of the seventh embodiment, the first end surface 110, the side surface 111, the second end surface 120 and the circular arc surface 121 of the supporting strip 1 may also be subjected to surface treatment such as sand blasting or acid etching to increase surface roughness and improve adhesion of bone, so that the bone can be firmly bonded to the supporting strip 1 after covering the supporting strip.

In summary, in the supporting device 100 of the embodiments, the supporting strip 1 supports the biofilm 4 by the smooth arc-shaped surface 121, so that the dental pulp can be prevented from being punctured by any one of the end sections 12 during the healing period, and the bone supplementing area can be prevented from being exposed to cause operation failure. In addition, by means of the design of the holding pieces 2, the biological membrane 4 can be very conveniently and rapidly fixed on the supporting bar 1, so that the situation that the biological membrane 4 shakes relative to the supporting bar 1 is prevented. In the first embodiment, since the supporting strip 1 is elongated and can cross over the corner 341 (as shown in fig. 3), the user can stably support the biological membrane 4 by using a single set of the supporting device 100, thereby improving the convenience of assembly and use and post-operation disassembly. In the second and third embodiments, the supporting strip 1 can be bent into an inverted U shape to support the biological membrane 4, so as to stably support the biological membrane 4. In the first to sixth embodiments, since the supporting strip 1 is formed with the through holes 112 for the bone screws 5 to pass through respectively only in the middle section 11 without other holes, the soft tissue of the dental pulp can be prevented from growing into the supporting strip 1 and adhering thereto during the healing period. Therefore, after the dental pulp is healed, a groove is cut in the dental pulp, the clamping piece 2 is firstly detached from the supporting strip 1, and then the bone nail 5 is screwed down, so that the supporting strip 1 can be conveniently and quickly taken out. In the seventh embodiment, by keeping the supporting strip 1 at the specific position without removing it, the bone absorption at the buccal side 32 can be reduced, and the objective of the present invention can be achieved.
