Description

Technical Field

[0001] The utility model relates to the technical fields of restorative medicine, dental medicine and dental implantology, and in particular to a component with a supporting function for the upper palate soft tissue that falls during the healing process of dental implantation. Background Art

[0002] In the 1950s, Swedish scientist Brånemark discovered the bone-binding phenomenon of titanium metal and applied it to make artificial tooth roots, on which denture parts were installed to restore the functions of lost teeth. Since then, this tooth-missing repair technology has developed rapidly and has now become the first choice for tooth-missing repair treatment. This titanium dental implant technology has enabled thousands of tooth-missing patients to receive effective treatment, thereby restoring their chewing function. In addition, it also restores and obtains the aesthetic function and effect of teeth. Therefore, it is considered to be one of the greatest utility models of mankind in this century and is known as "the third set of teeth for mankind."

[0003] The screw-shaped artificial tooth root made of titanium metal, i.e. the implant, is implanted into the human jawbone. When the bone heals, the human bone tissue can grow firmly on the titanium metal, which enables the implant to be fixed in the jawbone. Therefore, it can serve as a basis to support the denture components, i.e. the false teeth, installed thereon, thereby achieving the artificial restoration of lost teeth, that is, replacing lost teeth with artificial implants, so that the chewing function and aesthetic function of the teeth here can be restored.

[0004] Modern titanium dental implants are composed of three major parts to form their basic structure, namely the implant, the abutment and the crown. The implant is an artificial tooth root, and the abutment is a component that is in the middle position and connects the upper and lower parts. "Connecting the upper part" means that it bears the crown, that is, the crown is installed on it, and "connecting the lower part" means that it must be connected to the implant. Since the implant must be implanted into the human jawbone through a special surgical operation and will undergo a long healing process, this structure allows the abutment and crown to be removed from the implant at any time without having a major impact on the implant, so it can be easily repaired.

[0005] There is no doubt that in order to implant a tooth in a part of the body, there must be a "bone" that can accommodate the implant, that is, there must be a sufficient amount of jawbone to place the implant, just like planting a tree requires soil of sufficient depth and area to plant the tree. In reality, the part where the patient needs to implant is often not suitable for implantation due to insufficient bone volume. For this reason, bone transplantation is often used in dental implant treatment technology to solve the problem. Autologous bone can be transplanted, and bone can also be increased by other means, such as using artificial bone. When the bone is grafted and the bone volume is appropriate, the implant surgery can be performed. In addition, the implant surgery will cause a soft tissue / gingival wound, which must be healed and grown in the manner required for the repair, that is, a channel is left to reach the implant to expose the top of the implant for installing the abutment and crown. For this reason, there are special healing components, such as the healing abutment, which is installed on the implant during the operation and the gums are sutured. In this way, after the gum soft tissue heals, the required channel can be formed.

[0006] In view of the fact that the zygomatic bone is thick and solid, around 1989, Brånemark proposed the concept of zygomatic implants to achieve "bone-free implantation" in response to severe atrophy and absorption or complete disappearance of the maxillary bone. This was to solve the problem that conventional implants could not be used to repair missing teeth due to severe atrophy and absorption of the maxillary bone. As a result, Brånemark and Nobel Biocare created the Zygoma zygomatic implant, which was proven to be effective after a long period of clinical application research and was launched on the market in 2000.

[0007] Through extensive practice and observation, the inventor of the present invention has found that although zygomatic bone implants are also suitable for cases of partial mandibular resection, such as the lower zygomatic area after bone tumor resection, or those where bone tissue is lost or remodeled due to other reasons, such as bone loss caused by mechanical trauma, conventional implants cannot be used, and zygomatic bone grafting is inconvenient or not suitable to be included in the preferred treatment plan.

[0008] In addition, compared with conventional implants, the implantation surgery of zygomatic implants is different. The operation is large-scale, the surgical technique is complex, and there are surgical traumas. In the later stages of the implantation process, there are more and stricter requirements for soft tissue trimming, bone wrapping, and suturing. This is especially true after soft tissue transplantation. Since the transplanted tissue blocks / flaps are independent and relatively thick, and people spend a considerable amount of time in a standing position, they will sag due to gravity, thus affecting the growth direction of the transplanted soft tissue during the healing process.

[0009] Due to the particularity of the indications and implantation surgery of zygomatic implants, their application has been difficult and the pace of promotion has been slow since their launch in 2000. However, in the past decade or so, the number of applications has gradually increased, and more developers have launched new products, which shows that zygomatic implant technology is still developing. For example, the famous Swiss Straumann company, which is at the forefront of the world's dental implant products and technologies, also announced its ZAGA series of zygomatic implants in early 2021. These technological developments and advances make it possible for such patients to have artificial dental implants through zygomatic implant implantation and restoration surgery to regain chewing function. However, the present inventor has found in a lot of practice that during implementation, Zygomatic implant surgery lacks auxiliary means for soft tissue healing, so surgeons often have to find ways to solve the problem on the operating table with temporary instruments. This makes it difficult to complete the operation quickly and smoothly, resulting in a prolonged operation. Especially in unexpected situations such as the thickness of the transplanted soft tissue greatly exceeds the expected thickness, the surgeon has to find temporary ways to deal with and solve the problem. One minute longer in surgery means an increase in surgical risk and one minute longer pain for the patient. As for postoperative healing, a considerable part of the human body is in a standing position, and the zygomatic implant will undoubtedly fall due to gravity, which will prolong the healing time.

DETAILED DESCRIPTION

[0060] The present invention is described in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0061] Since the disc-shaped tray 1 (or tongue-shaped tray) of the utility model is located between the tongue and the soft tissue of the upper palate of the oral cavity, it can support the implanted soft tissue from possibly falling during the healing process, so as to maximize the healing of the implanted soft tissue according to the healing mode expected by the doctor, reduce the healing time, and avoid medical disputes.

[0062] In addition, the disc-shaped support 1 provided by the utility model also has a restraining effect on the soft tissue of the upper palate during the trimming and suturing process.

[0063] like Figure 1 As shown, the upper palate soft tissue healing device for dental implantation provided by the utility model comprises a disc-shaped tray 1 which has a supporting effect on the sagging of the upper palate soft tissue during the healing process, and a fixing member 2 which fixes the disc-shaped tray 1 to the upper palate soft palate.

[0064] The contour shape of the disc-shaped support body 1a depends on the shape of the implanted soft tissue, and its contour type includes a four-rounded rectangle and an ellipse. The disc-shaped support body 1a is made of transparent polymer materials: PETG material, transparent K resin, transparent nylon, so that the surgeon can observe during the operation and then plan the position of the through hole 1c.

[0065] like Figure 2 As shown, the horizontal end surface of the rear end of the disc-type support body 1a is provided with 1 or 2 vertical through holes 1c for placing the fixing member 2, the purpose of which is to fix the disc-type support body 1a to the patient's upper zygomatic bone through the fixing member 2, based on the two holes set on the horizontal end surface of the rear end of the disc-type support 1 in this utility model. The handle 1d is a temporary handle or operating member used by the physician during surgery. The upper side surface 1b is the side of the disc-type support body 1a adjacent to the soft tissue of the upper palate; the lower side surface is the side adjacent to the upper side surface 1b of the disc-type support body 1a. The front or back refers to the tip and root of the tongue.

[0066] The upper fixing member 2-1 is a cylindrical fixing member with a central mounting platform 2-1a and a cylindrical boss 2-1c at the upper and lower ends respectively.

[0067] The fixing member 2 is a cylindrical fixing member with a coaxial core composed of an upper fixing member 2-1 and a lower fixing member 2-2. The upper end of the upper fixing member 2-1 is connected to a basic fixing member (implant nut, not shown in the drawings of the utility model) provided on the zygomatic tissue, and the lower end of the upper fixing member 2-1 vertically passes through the implanted soft tissue and the disc-shaped support 1 in sequence, and then is fixedly connected to the coaxial core of the basic fixing member through the lower fixing member 2-2, thereby supporting the implanted soft tissue from falling due to gravity during the healing process.

[0068] like Figure 3 As shown, the cross section of the upper end of the upper fixing member 2-1 includes a central mounting platform 2-1a and an annular sinking groove 2-1b surrounding the central mounting platform 2-1a. The central mounting platform 2-1a is composed of two sections, the upper section is a threaded section, and the lower section is a cylindrical section, so as to be fixedly connected with a basic fixing member (not shown in the drawings of the present utility model) provided on the zygomatic tissue.

[0070] The central mounting platform 2-1a in the upper fixing member 2-1 is composed of a threaded upper section 2-1e with external threads and a cylindrical lower section; the height of the upper section is equal to or greater than the depth of the annular sinking groove 2-1b.

[0071] The central mounting platform 2-1a and the annular sinking groove 2-1b at the upper end of the upper fixing member 2-1 are components that match the corresponding settings at the lower end of the basic fixing member of the zygomatic tissue, so as to fix the disc-type support body 1a through the mutual connection between the upper fixing member 2-1 and the lower fixing member 2-2.

[0072] like Figure 4 As shown, the lower fixing member 2-2 consists of three sections; the middle section is a regular polygonal section, and the other two sections are respectively a frustum section 2-2a and a threaded section 2-2c; the center of the frustum section 2-2a is provided with a frustum with a regular polygonal sinking hole 2-2b in its axial cross section.

[0073] The lower fixing member 2-2 is composed of three sections, namely a regular polygon section and a threaded section 2-2c, which respectively match the inner wall of the cylindrical boss 2-1c at the lower end of the upper fixing member 2-1, including a regular polygon lower section 2-1d and a threaded upper section 2-1e, to fix the disc-type support body 1a.

[0074] The regular polygon lower section 2-1d and the threaded upper section 2-1e of the inner wall in the lower end of the upper fixing member 2-1 are respectively the accommodating sections of the regular polygon section and the threaded section of the lower fixing member 2-2. The term "accommodating" means that the regular polygons and threads of the two match each other.

[0075] The following is combined with Figures 5 to 13 14 to 17 provide a detailed description of the punching mechanism 5 in the processing instrument of the upper palate soft tissue healing device for dental implantation provided by the utility model:

[0076] The hole of the dish-shaped tray 1 used in the healing process and the cutting thereof in the technical solution provided by the utility model are the embarrassing situation that the patient is in on the operating table, but the doctor does not have a satisfactory instrument to solve it. Figure 5 As shown, the punching device of the utility model is a device urgently needed in the process of setting the disc-type tray 1 at this specific moment when both the doctor and the patient are. Considering that the rectangular support base plate 5c in the present application is a rectangle, the "longitudinal" in the term "longitudinal lever" refers to the length direction of the specific shape of the rectangle; the "transverse" in the term "threaded hole 5a5" refers to its width direction; the "vertical" in the term "vertical frame" refers to the direction perpendicular to the length.

[0077] In the preferred technical solution provided in this application, Fig.12 As shown, the force required for drilling the disc tray 1 is transmitted through the pin 5b ( Fig.11 ) to the 5d3 sink hole at the left end ( Fig.12 The punch 5f in the punching tool (not shown) is provoked by this force, and the punch 5f of the punching tool slowly extends from the spring 5g and enters Fig.10 The hole (5a9, 5a4) with a larger bottom and a smaller top on one side of the F member in the shown member 5a, to the force-bearing boss 5a2 for punching holes in the dish-type support 1. The transmission path of the force for punching holes in the dish-type support 1 is an inverted L-shaped path, which is transmitted from the longitudinal lever-type operating handle 5d to the hole (5a9, 5a4) with a larger bottom and a smaller top on one side of the vertical F member.

[0078] like Fig. 9As shown, the frame 5a includes an N-shaped component 5a3 and an inverted L-shaped component 5a1 that are interconnected; the first through hole 5a2 on the inverted L-shaped component 5a1 and the second through hole 5a4 on the N-shaped component 5a3 are coaxially arranged, the N-shaped component 5a3 has a transverse channel 5a6 for accommodating a lever-type operating handle 5d, an axial hole 5a7 for installing a pin 5b, a fixing screw hole 5a8, a second vertical through hole 5a9 and a rounded corner 5a10, and a component whose height is equal to that of the inverted L-shaped component and is integrally formed relative to the inverted L-shaped component, and the horizontal area of ​​the inverted L-shaped component at the height is larger than the horizontal area of ​​the disc-type tray 1 to be punched, so as to facilitate the placement of the disc-type tray 1 during punching.

[0079] like Fig.10 As shown, the vertical frame 5a includes: the F-shaped component is vertically provided with a punch 5f located on the supporting end 5d3 of the lever-type operating handle 5d, and a second vertical through hole 5a9 and a second through hole 5a4 of two specifications with a large lower diameter and a small upper diameter that can move freely up and down after extending from the spring 5g.

[0080] The frame 5a is provided with a threaded hole 5a5 of the same diameter and coaxial core for the pin shaft 5b as the support rod of the longitudinal lever-type operating handle 5d to pass through horizontally at the same height of the cross section of the force-applying end 5d1 of the long lever 5d2 of the lever-type operating handle 5d, so as to flexibly connect the lever-type operating handle 5d to the transverse channel 5a6 between the front and rear sides of the vertical frame 5a, thereby realizing the flexibly connecting the lever-type operating handle 5d to the frame 5a. The vertical frame 5a is fixed to the rectangular supporting bottom plate 5c by base bolts 5e.

[0081] The vertical distance between the transverse through hole 5a5 in the frame 5a and the rectangular support base plate 5c is 3 to 8 cm.

[0082] like Figure 8 As shown, the pin 5b that passes through the holes 5a5 on the front and rear sides of the frame 5a and the supporting shaft hole 5d4 of the lever-type operating handle 5d is not only a pin connecting the two components, but also a fulcrum for the lever-type operating handle 5d to swing up and down along the pin 5b when a force is applied, thereby driving the punch 5f of the punching tool to rise and punch a hole in the disc-type tray 1.

[0083] The distance ratio between the support shaft hole 5d4 of the lever-type operating handle 5d and the support end 5d3 and the operating end or force-applying end 5d1 is 1:1-3.5;

[0084] The frame 5a is an F-shaped member composed of two inverted L-shaped members, and a member whose height is equal to that of the inverted L-shaped member and is relatively arranged as an integral part. The horizontal area of ​​the height of the inverted L-shaped member is larger than the horizontal area of ​​the disc-type tray 1 to be punched, so as to facilitate the placement of the disc-type tray 1 during punching.

[0085] The distance between the support shaft hole 5d4 of the lever-type operating handle 5d and the operating end 5d1 at the right end is equal to the distance between the support shaft hole 5d4 and the right end of the rectangular supporting bottom plate 5c.

[0086] like Fig.13 As shown, the punch 5f includes a punch seat 5f3, a tool rod 5f2 fixed to one side of the punch seat 5f3, and a punch cutting edge 5f1 arranged at the end of the tool rod 5f2.

[0089] The upper pliers body 6a and the lower pliers body 6b are connected by an interference fit of the pliers shaft 6c;

[0090] The ends of the upper clamp body 6a and the lower clamp body 6b are arc-shaped ends with mirror-symmetric relationship. ， When the two pliers are closed, an arc-shaped shearing end is formed at the end.

[0091] like Figure 14-17 As shown, the cutting pliers 6 of the present invention are composed of upper and lower pliers bodies 6a and 6b, a cutting pliers shaft 6c, and upper and lower finger rings 6e and 6d.

[0092] One side of the pliers shaft is a mushroom-shaped head, and the other side is expanded and fixed by riveting and cannot be withdrawn. Therefore, after assembly and riveting, it becomes an inseparable part; the upper and lower pliers bodies are made of metal, and the ends are provided with jaws 6a1, which are mirror-symmetrical. When the jaws are closed, the shearing blades of the upper and lower jaws are aligned, just like nail scissors. Fig.15 The cross-sectional views (c) and (d) show this jaw structure. Fig.15 6(d) is an enlarged view of (c), and the cross section is obtained by cutting off part of the jaws along the imaginary cutting plane 6f, obtaining the cross section of the cut part, and flipping it flat. Therefore, when the upper and lower jaws are closed, the handle 1d of the disc-type tray 1 can be cut off; the jaws 6a1 are not perpendicular to the upper and lower jaw bodies, but are tilted outward at an angle, such as Fig.15As shown in (b), the angle is between 10° and 20°. This structure allows the pliers to cut close to the base of the handle 1d of the disc holder 1. Fig.17 It is displayed here.

[0093] The upper finger ring 6e is a single-finger ring, and the lower finger ring 6d is a double-finger ring. When cutting, the thumb enters the upper finger ring, and for the lower finger ring, two fingers can enter. There are two ways. The first way is to enter with the index finger and the middle finger, and the second way is to enter with the middle finger and the ring finger. At this time, the index finger presses outside the finger ring. Therefore, compared with the classic "two-finger" surgical scissors, the scissors 6 of the utility model can obtain greater cutting force.

[0094] The upper pliers 6a and the lower pliers 6b can be made of a whole piece of metal, or they can be first cold extruded and then precision machined for the mating parts, or the main parts of the upper and lower pliers can be made by sheet metal stamping, and the jaws are separately machined and then welded to the upper and lower pliers. The jaws need to be hardened. Fig.16 The upper and lower pliers bodies and their riveted structure with the pliers shaft 6c are shown, and the structure is all metal.

[0095] The upper and lower finger rings are made of polymer material by integral injection molding, and are of integral structure. The small end is the connecting end with the clamp body, and both have rectangular holes, into which the connecting ends of the upper clamp body 6a and the lower clamp body 6b can be embedded and sealed with glue; the finger ring material can be polyoxymethylene POM or nylon.

[0096] In addition to trimming the handle 1d of the disc tray 1, the scissors 6 can also be used to trim the contour shape of the disc tray 1. The surgeon determines the trimming and trimming target at the operation site according to the specific conditions of the patient's oral surgery site.

[0097] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the claims of the present invention and within the equivalent technology, the present invention is also intended to include these changes and variations.
