Abstract

A customized osteotome for tooth auto-transplantation surgery comprises an analog of donor tooth and a handle. The analog has the same appearance as a donor tooth and includes a root portion and a crown portion; in addition, a first connecting structure is furnished at the crown portion. A front end of the handle is furnished with a second connecting structure which is connectable with the first connecting structure of the crown portion. When the handle and the analog are connected by means of the first and second connecting structures, the root portion of the analog acts as the osteotome tip of customized osteotome for drilling a socket (i.e., recipient socket) corresponding to the contour of the root portion at the alveolar bone (i.e., the edentulous ridge of recipient area). Therefore, the recipient socket can be formed at the edentulous ridge of recipient area by using the root portion of analog before extracting the donor tooth, such that the recipient socket is perfect fit with the root of donor tooth. Not only the Extra-Alveolar Time (EAT) is shortened, but also the degree of damage to the Periodontal Ligament (PDL) of the root of donor tooth is reduced, so as to improve the chances of successful tooth auto-transplantation surgery.

Description

Osteotome for autologous tooth transplantation and its simulating body and manufacturing method of simulating body

The present invention is related to an osteotome for autologous tooth transplantation and a method for manufacturing a simulated body and a simulated body, especially a method suitable for tooth auto-transplantation (Tooth Auto-Transplantation; TAT) surgery. An osteotome with the same appearance as the donated tooth to excavate the implant seat in the donation area, as well as the structure and manufacturing method of the simulated body.

Tooth Auto-Transplantation (TAT) involves the extraction of healthy teeth (such as molars or wisdom teeth; referred to as Donor Tooth) located in other parts of the oral cavity from the mouth of patients with missing teeth and autotransplanting them to The surgical technique on the ridge of the missing teeth (also known as the donation area) is considered to be one of the feasible techniques for replacing missing teeth. In order to ensure that the roots of the donated tooth can heal and heal smoothly after being transplanted to the ridge of the recipient area, whether the root surface of the donated tooth can retain a healthy and viable periodontal ligament (PDL) is the most important thing. Important factor. Therefore, in addition to the process of extracting and implanting the donor tooth, it is necessary to avoid damaging the periodontal ligament on the root surface or minimize the periodontal ligament damage. It is also necessary to shorten the period from the extraction of the donated tooth to the implantation of the donated tooth as much as possible. The entire process of entering the donation area is the time during which the root of the donated tooth is exposed to the outside world (Extra-Alveolar Time; EAT for short). Generally speaking, the EAT time of this process should be shorter than 15 minutes, otherwise it will increase the risk of the donor tooth being transplanted to the recipient area and unable to heal and recover smoothly.

Traditional tooth autotransplantation requires the clinician to extract the donated tooth, and then based on the clinician’s own visual observation of the root shape of the donated tooth. Existing dental tools are used on the tooth spine to chisel a Recipient Socket (RS) that conforms to the shape of the root of the donated tooth. Obviously, this process will greatly increase the EAT time and increase the risk of failure of the TAT operation. Later, someone developed an image of the root shape of the donated tooth by taking X-rays or other methods, allowing clinicians to use existing dental tools on the ridge of the donation area before extracting the donated tooth. An implant that roughly conforms to the shape of the root of the donated tooth is cut out, in order to shorten the time for implanting the root of the donated tooth into the implant of the donation area after extracting the donated tooth. However, because the shape of the existing dental tools used for drilling cannot match the shape of the root of the donated tooth, the shape of the implant seat that is chiseled out will inevitably be different from the shape of the actual root of the donated tooth. Difference; therefore, when the clinician tries to implant the extracted root of the donated tooth into the implant seat in the donation area, it is not only unavoidable to avoid collision and compression between the root of the donated tooth and the non-compliant implant seat. Periodontal ligament damage also requires extra EAT time for clinicians to fine-tune the shape of the implant (for example, local fine chiseling or filling powder) so as to correctly conform to the root shape of the donated tooth. In addition, according to the existing TAT technology, it is not possible to pre-detect whether the size of the donated tooth and the shape of the root are suitable for transplantation to the donation area. If the implantation of the donation area is completed, and the steps of extracting the donation tooth, it is discovered If the size or shape of the donated tooth and the donation area is not appropriate, the implant seat and the donation tooth in the donation area will be wasted. Therefore, there is still room for further improvement of the existing tooth autotransplantation technique.

For this reason, the main purpose of the present invention is to provide an osteotome for autologous tooth transplantation and its simulant body and a method for manufacturing the simulant body, by making a hard material simulant body that conforms to the shape of the donated tooth and its root. Later, a root of the simulated body is directly used as a chisel tip, so as to chisel out a recess in the alveolar bone of the human body (that is, the ridge of the donation area) that conforms to the outline of the root. Acupuncture point (ie, implant seat). In this way, the root of the simulated body can be used to make an implant in the donation area before the donation tooth is extracted, so that the shape of the implant can correctly conform to the root shape of the donation tooth; not only can the EAT time be shortened, but also It can also reduce the degree of damage to the periodontal ligament on the root surface of the donated tooth, thereby increasing the chance of smooth healing and recovery of the donated tooth in the autologous tooth transplant operation after being transplanted to the donation area.

Another object of the present invention is to provide a device and mold for autologous tooth transplantation For phantoms, you can simulate the state of the donated tooth after being transplanted to the donation area with a computer before performing the autogenous tooth transplant operation, and check in advance whether the size of the donated tooth and the shape of the root are suitable for being transplanted to the donation area, so as to avoid performing invalid self-transplantation. Body tooth transplant surgery.

To achieve the above objective, the present invention provides an osteotome and a simulated body for autologous tooth transplantation, which is suitable for the operation of autologous tooth transplantation of a human body, and includes: a simulated body and a grip rod. The simulation body is made of hard materials and has a tooth shape, which includes a tooth root and a tooth crown; and a first coupling structure is provided on the tooth crown. The grip is a rod-shaped structure and includes: a second coupling structure located at a front end of the grip, a handle located at a rear end of the grip, and connected between the second coupling structure and the grip Of a rod. Both the second coupling structure of the grip and the first coupling structure of the simulation body can be combined and fixed in a detachable manner; and, when both the grip and the simulation body are connected to the second combination structure by the second combination structure and the simulation body When the first connecting structure is combined and fixed into one body, the tooth root of the simulated body is used as a chisel tip for chiseling a cavity in the alveolar bone of a human body that conforms to the contour of the tooth root.

In one embodiment, one of the first coupling structure and the second coupling structure is a protruding bolt and the other is a concave nut, so that the first coupling structure and the second coupling structure are both It can be screwed and locked to each other.

In one embodiment, the osteotome further includes an ultrasonic vibration machine connected to the grip rod; the ultrasonic vibration machine can generate ultrasonic vibrations on the analog body located at the front end of the grip rod to facilitate the simulation The operation of the tooth root of the body to chisel the cavity in the alveolar bone of the human body that conforms to the contour of the tooth root.

In order to more clearly describe the osteotome for autologous tooth transplantation proposed by the present invention and its simulated body and the manufacturing method of the simulated body, it will be described in detail below in conjunction with the drawings.

The osteotome for autologous tooth transplantation of the present invention is mainly suitable for autologous tooth transplantation operations, and includes a simulated body and a grip rod. The simulated body has the same appearance as a donated tooth and includes a root portion and a crown portion; and a first coupling structure is provided on the crown portion. A second coupling structure is provided at the front end of the grip rod, which can be combined and fixed with the first coupling structure of the simulation body. And, when the grip and the simulated body are combined by the first and second coupling structures, the root of the simulated body is used as a chisel tip for the alveolar bone (that is, the donation area). A cavity (that is, an implant seat) conforming to the contour of the root of the tooth is chiseled out at the ridge of the tooth. In this way, the root of the simulated body can be used to make an implant in the donation area before the donation tooth is extracted, so that the shape of the implant can correctly conform to the root shape of the donation tooth; not only can the root of the donation tooth be shortened Exposure to the outside world can also reduce the degree of damage to the periodontal ligament on the root surface of the donated tooth, thereby increasing the chance of smooth healing and recovery of the donated tooth in the autologous tooth transplant operation after being transplanted to the donation area.

As shown in Figure 1, it is a schematic diagram of a typical example of the teeth of a patient who wants to undergo autologous tooth transplantation. The patient 10 has a lack of teeth in the front teeth (also referred to as the donation area 11), which is less beautiful and easily hinders the bite function. Therefore, the back of the patient's oral cavity can be less aesthetically affected and relatively non-functional teeth (such as molars). Or wisdom tooth; Donor Tooth for short) is transplanted to the donation area 11 through Tooth Auto-Transplantation (TAT) surgery. Because patient 10’s own living teeth are used for transplantation, there will be no defects of tissue rejection or absorption after transplantation. Periodontal ligament (PDL) on the surface of the root 122 of the donor tooth 12 is transplanted to the oral donation area 11. Can continue to survive and keep teeth healthy.

Please refer to Figure 2, which is a schematic diagram of an embodiment of the osteotome for autologous tooth transplantation of the present invention. In order to improve the success rate of autologous tooth transplantation, the present invention discloses an osteotome for autologous tooth transplantation, which can easily and quickly chisel out an accurate tooth on the ridge of the donation area 11 before the donation tooth 12 is extracted. An implant socket (Recipient Socket, RS for short) that conforms to the contour and size of the tooth root 122 of the donated tooth 12. The osteotome includes: a simulation body 20 and a holding rod 30. The simulation body 20 is made of a hard material, such as but not limited to a metal material having a hardness higher than that of the tooth ridge of the donation area 11 (for example, but not limited to: medical stainless steel 304 or 316). The outline and size of the simulated body 20 conform to the outline and size of the tooth, that is, the donation tooth 12, and it includes a crown portion 21 and a root portion 22; and a crown portion 21 is provided on the top surface of the crown portion 21. A combined structure 23. The outline and size of the crown portion 21 and the root portion 22 of the simulated body 20 correspond to the crown 121 and the root 122 of the donated tooth 12 as shown in FIG. 1, respectively. The grip 30 is a slender rod-shaped structure, the material of which is preferably metal, and it has a second coupling structure 33 at a front end of the grip 30, a grip 31 at a rear end of the grip 30, And a rod 32 connected between the second coupling structure 33 and the handle 31. In this embodiment, the total length of the grip rod 30 may be between 8-25 cm, and the diameter of the rod body 32 may be between 0.3-1 cm. The outer surface of the handle 31 can be optionally provided with a non-slip uneven surface to improve the stability of the grip. A bending part 321 is designed in the middle section of the rod body 32 or the area near the front end, so that the extension direction of the front end and the rear end of the rod body 32 are not on the same axis. Such a bending structure of the rod body 32 can allow It is more convenient for the clinician to perform the drilling operation of the implant seat located in the upper jaw of the oral cavity or the inner side of the donation area 11. It is understandable that the degree of bending and the setting position of the bending portion 321 of the rod body 32 can be changed according to the requirements of the location of the donation area; or, several grips with different degrees of bending portions 321 can be made in advance. 30 spare, so that clinicians can choose different grips according to the actual needs of different patients during autologous tooth transplantation 30.

In the present invention, the second coupling structure 33 of the grip 30 and the first coupling structure 23 of the simulation body 20 can be combined and fixed in a detachable manner; for example, the first coupling structure 23 and the first coupling structure 23 One of the two second coupling structures 33 is a protruding bolt and the other is a concave nut, so that the first coupling structure 23 and the second coupling structure 33 can be screwed, locked and disassembled with each other. In this embodiment, the first coupling structure 23 provided on the simulation body 20 is a nut, and the second coupling structure 33 provided at the front end of the grip 30 is a bolt. As shown in Figure 3, it is a schematic diagram of an embodiment of the present invention when the grip of the osteotome for autologous tooth transplantation is combined with the simulated body. When the grip 30 and the simulation body 20 are combined and fixed into one body by the second connection structure 33 and the first connection structure 23, the root portion 22 of the simulation body 20 is used as a chisel tip for A cavity (implant seat) conforming to the contour of the tooth root is chiseled at the tooth ridge of the donation area 11. In other words, in the present invention, the tool used to chisel out the implant is the root portion of the simulated body that has the same outline and size as the root portion 122 of the donated tooth 12. Therefore, when an autologous tooth transplant operation is to be performed, the clinician can operate the osteotome before extracting the donated tooth 12 and use the root of the simulated body as the tip of the chisel to be placed on the ridge of the donation area 11 in advance. An implant seat that accurately conforms to the contour and size of the tooth root 122 of the donated tooth 12 is conveniently and quickly chiseled out. It can not only shorten the exposure time (EAT) of the root 122 of the donated tooth 12, but also reduce the degree of damage to the periodontal ligament on the surface of the donated tooth root, thereby improving the transplantation of the donated tooth 12 during autologous tooth transplantation. After arriving at the donation area 11, there will be opportunities for smooth healing and recovery, which will greatly improve the various deficiencies of conventional technologies.

In other embodiments of the osteotome for autologous tooth transplantation of the present invention described below, since most of the components are the same or similar to the previous embodiments, the same or similar components will be given the same names and numbers, and I won't repeat the details.

Please refer to Figure 4, which is a schematic diagram of another embodiment of the osteotome for autologous tooth transplantation of the present invention. In this embodiment, the osteotome of the present invention also includes a simulation body 20a and a grip 30a. The only difference from the embodiment shown in FIG. 2 is that, in the embodiment shown in FIG. The first coupling structure 23a on the top surface of the crown 21 of the body 20a is a bolt, and the second coupling structure 33a provided at the front end of the grip 30a is a nut that can be interlocked with the first coupling structure 23a.

Please refer to FIG. 5, which is a schematic diagram of another embodiment of the osteotome for autologous tooth transplantation according to the present invention. In this embodiment, the osteotome of the present invention further includes an ultrasonic vibrator 392 (or piezoelectric vibrator), which is connected to the grip 30 by a connecting wire 391. The ultrasonic vibration machine 392 can The simulation body 20 combined with the front end of the grip 30 is made to generate ultrasonic vibrations to promote the tooth root 22 of the simulation body 20 to gouge out at the alveolar bone of the donation area in the patient's oral cavity to conform to the contour of the tooth root 22 The operation of the cavity (implant seat).

Please refer to Figure 6, which is a schematic diagram of an embodiment of the osteotome for autologous tooth transplantation of the present invention after transplanting the donated tooth to the donation area. As shown in the figure, once the operation of chiseling out the implant seat in the donation area is completed, the clinician can extract the donated tooth 12 from its original position 18 and transplant it to the implant seat in the donation area. After that, the suture 19 is used to position the donated tooth 12 in the donation area with the conventional suture technique, and the operation of the autologous tooth transplantation operation is completed, without any other splint device to fix the donated tooth 12. After a period of time (for example, a week or so) of the tissues near the recipient area and the periodontal ligament on the surface of the tooth root 122 of the donor tooth 12, the sutures are removed, and endodontic treatment of the transplanted tooth is performed. Generally speaking, the endodontic treatment can be completed about four weeks after the operation, and then the prosthesis treatment can be completed about three months after the operation. In the present invention, since the contour and size of the implant seat already correctly conform to the contour and size of the root portion 122 of the donated tooth 12, it can not only greatly shorten the exposure of the root 122 of the donated tooth 12 to the outside world. The time (EAT) can also reduce the degree of damage to the periodontal ligament on the root surface of the donated tooth 12, thereby increasing the chance of the donor tooth 12 for autologous tooth transplantation to heal and recover after being transplanted to the donation area 11. .

Please refer to FIG. 7, which is a flowchart of an embodiment of manufacturing a simulated body of the osteotome of the present invention and using the osteotome to perform an autologous tooth transplantation operation. As shown in the figure, an embodiment of the manufacturing method of the simulated body of the osteotome of the present invention and the using method thereof includes the following steps:

Step 31: Scan the appearance of the donated tooth and obtain a 3D (Three Dimensional) image of the appearance of a donated tooth. Wherein, the 3D image of the donated tooth can be a tomographic scan of the patient’s oral cavity by a Computed Tomography (CT) to obtain the bone 3D image of the patient’s oral cavity including the donated area and the donated tooth, which is based on There are types of digital information files that can be interpreted and processed by the computer, such as but not limited to: digital information files with the extension ".STL". After obtaining the 3D images of the bones in the donation area and the donated tooth, the 3D images of the donated tooth are separated and transplanted to the donation area by computer simulation, so that the 3D image of the donated tooth can be transferred to the donation area before the autologous tooth transplantation is performed. The computer simulates the condition of the donated tooth after being transplanted to the donation area to check the feasibility of autologous tooth transplantation. If the size of the donated tooth does not match the size of the donation area after simulation, it may be necessary to further consider performing an additional osteotomy (Osteotomy) Or even abandon the autologous tooth transplant operation, and avoid the execution of the failed autologous tooth transplant operation in advance.

Step 32: Manufacture a simulated body of the donated tooth. Once the 3D image of the donated tooth is separated by a computer operation, the simulated body can be made according to the 3D image of the donated tooth, and the first coupling structure is provided on the crown of the simulated body. In this embodiment, the method of making the simulation body can be one of the following: using a conventional 3D metal printer to produce the simulation body, using a conventional CNC (Computer Numerical Control; computer numerical control) A processing machine is used to produce the simulation body. Wherein, as shown in step 33, the first coupling structure can be formed integrally with the simulated body, or, after the crown and root of the simulated body are made, the crown and root of the simulated body can be additionally placed on the crown of the tooth. The surface processing sets the first coupling structure (for example, welding bolts or cutting nuts). After that, after the production of the simulated body provided with the first coupling structure is completed, the simulated body needs to be disinfected and other subsequent treatments in a conventional manner for the formal operation.

Step 34: Lock the simulated body to the hand-held instrument (ie, osteotome). Before performing the autologous tooth transplantation operation, the second coupling structure of the front end of the grip of the present invention is locked to the first coupling structure on the top surface of the simulated body to form an integral part that can be held by the physician as shown in FIG. Osteotome.

Step 35: Use the simulated body to excavate the tooth root in the donated area and then remove the simulated body. When autologous tooth transplantation is performed and the donated tooth has not been extracted, the clinician first holds the grip of the osteotome and uses the root of the simulated body as the tip of the chisel for use in the donation area of the patient’s oral cavity. A cavity conforming to the contour of the root of the simulated body is chiseled out of the tooth spine to serve as an implant seat. Since the root of the simulated body is made based on the 3D image of the root of the donated tooth, the internal shape, contour and size of the implant chiseled out by the root of the simulated body can certainly fit the donated tooth correctly. The outline and size of the root of the tooth. Because the ridges of the upper jaw of the human body are relatively soft, when the location of the donated area is in the upper jaw, the clinician can hold the osteotome and directly cut out the implant seat in the donated area; or, alternatively, osteotomy can be used first Drill a small hole in the tooth ridge of the donation area, and then directly dig out the implant seat in the donation area with an osteotome. However, when the location of the donation area is in the lower jaw, since the hardness of the lower jaw bone is relatively high, in this step, an ultrasonic vibration machine as shown in Figure 5 can be optionally used to promote the drilling of the implant. Chisel operation. After completing the drilling operation of the implant base, the simulated body can be removed from the patient's mouth, so that the donated area and the implant base are temporarily exposed to the outside world.

Step 36: Extract the donated tooth and transplant the donated tooth to the donation area and suture it. Once the excavation in the implant seat is completed, the clinician can extract the donated tooth from its original position and transplant it to the implant seat in the donation area, that is, place the root of the donation tooth into the implant in the donation area. Seated. After that, sutures are used to position the donated tooth in the donation area with the conventional suture technique to complete the operation of the autologous tooth transplantation. After the periodontal ligament on the surface of the tissues near the recipient area and the root of the donor tooth healed over a period of time, the sutures were removed. Since the contour and size of the implant seat already correctly conforms to the contour and size of the root of the donated tooth, it can not only greatly shorten the time (EAT) that the root 122 of the donated tooth 12 is exposed to the outside world (EAT), but also It can reduce the degree of damage to the periodontal ligament on the tooth root surface of the donor tooth, thereby increasing the chance of smooth healing and recovery of the donor tooth 12 of the autologous tooth transplant operation after being transplanted to the donation area 11.

However, the above-mentioned embodiments should not be used to limit the applicable scope of the present invention, and the protection scope of the present invention should be based on the technical spirit defined by the patented scope of the present invention and the scope included in its equivalent changes. That is to say, all equal changes and modifications made in accordance with the scope of the patent application of the present invention will still not lose the essence of the present invention, nor deviate from the spirit and scope of the present invention, and therefore should be regarded as a further implementation status of the present invention.
