Description

Technical Field

[0001] The utility model relates to an integrated device of a healing base and a scanning mold-taking rod, belonging to the technical field of medical equipment. Background Art

[0002] Dental implant technology has become the main way to repair missing teeth, which can restore good functions. Doctors are pursuing how to make the shape of dental implants closer to natural teeth to achieve better functions and aesthetic effects. In this regard, there is a lot of room for improvement in the gingival contour around dental implants. Since most of them are conical structures, they cannot form good bionic gingiva.

[0003] Patent CN203493761U discloses an aesthetic gingival healing abutment, comprising a connected abutment body and an abutment bottom, wherein the outer contour of the cross section of the abutment body is elliptical, and the area gradually decreases from top to bottom; a transfer rod insertion hole is provided at the upper part of the abutment body, and screw holes are provided at the lower part of the abutment body and the abutment bottom, and the transfer rod insertion hole is communicated with the screw hole; the outer contour of the cross section of the abutment body is similar to the shape of natural teeth, which has a good shaping effect on the gums; but since the healing abutment cannot fix and pull the gums, it often causes the gingival papilla to recede and flatten, which is not aesthetically pleasing and also increases the risk of food impaction.

[0004] At the same time, because the scanning rod is an essential tool for digital scanning, it has the functions of gingival penetration identification and implant mid-direction identification. Therefore, when taking an oral impression, it is generally necessary to remove the healing base, install the scanning rod on the implant, and then take the impression. After the impression is completed, the scanning rod is removed and the healing base is reinstalled. Doctors need to install different products back and forth when taking impressions, which causes pain to patients due to prolonged consultation time and increases the workload of doctors. Utility Model Content

[0005] In order to solve the above-mentioned problems existing in the prior art, the utility model provides an integrated device of a healing base and a scanning mold rod, which can form better bionic gums and enhance aesthetics. When necessary, the gums can be pulled and resin can be used to assist in sealing the wound, thereby better achieving primary healing of the wound. The integrated design can reduce the patient's pain and the doctor's workload.

[0006] The technical solution of the utility model is as follows:

[0007] A healing base and scanning mold rod integrated device, comprising a coaxially arranged healing body and a scanning shell, the scanning shell is provided with a scanning positioning part for scanning and positioning an implant, the healing body comprises an upper healing base and a lower healing base, the scanning shell wraps the upper healing base, the lower healing base is arranged through the scanning shell, the lower healing base is provided with an external thread, and the upper end of the upper healing base is provided with an internal thread; the outer contour of the cross section of the scanning shell is elliptical, and the area gradually decreases from top to bottom; the scanning shell and the upper healing base are connected and lead through holes are relatively provided.

[0008] Wherein, the scanning positioning portion includes an arc-shaped section opened on the end surface of the scanning shell, and at least one arc-shaped section is provided.

[0009] Among them, the integrated device of the healing base and the scanning mold taking rod also includes a matching rod, the bottom of the matching rod is a screw rod, the screw rod is threadedly connected to the upper healing base, and the top of the matching rod is a hexagonal nut.

[0010] The healing body and the scanning shell can be made of titanium alloy material or PEEK material.

[0011] Wherein, a status identification surface for acquiring intraoral data is arranged on the arc-shaped section.

[0012] The utility model has the following beneficial effects:

[0013] The device can directly scan and locate the implant by setting an arc section and a state recognition surface, which greatly reduces the operation steps and time of doctors taking impressions, and reduces the pain of patients caused by long consultation time; it also reduces the probability of the parts falling into the patient's oral cavity and throat due to the cyclic disassembly and installation of various parts, thus causing harm to the patient;

[0014] Furthermore, the device opens holes on the scanning shell and the healing body for threading sutures, which are used to fix the gingival tissue by dragging and pulling. This can reduce wound exposure during immediate implantation and help achieve wound closure when used with light-curing fluid resin. In addition, it also helps to retain or form gingival papillae, meeting the aesthetic needs of customers. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] See also Figure 1 to Figure 2 , the utility model provides a technical solution:

[0021] A healing base and scanning mold rod integrated device, comprising a coaxially arranged healing body 1 and a scanning shell 2, the healing body 1 comprising an upper healing base 11 and a lower healing base 12, the scanning shell 2 and the upper healing base 11 are integrally formed, the two are sleeved, the structure is compact, the space is small, and the operation in the oral cavity is convenient, the upper healing base 11 and the scanning shell 2 are integrally processed from titanium alloy, the elastic modulus is large, and the weight is light, the wear resistance, the biocompatibility is strong, and the service life is long; the bottom of the lower healing base 12 passes through the scanning shell 2, and the lower healing base 12 is provided with an external thread, the external thread of the lower healing base 12 matches the internal thread of the implant, the upper end of the upper healing base 11 is provided with an internal thread, the internal thread of the upper healing base 11 is used for fixed connection with the central screw inside the artificial crown, the outer contour of the cross section of the scanning shell 2 is elliptical, and the area gradually decreases from top to bottom, specifically, the scanning shell 2 as a whole is personalized according to the shape of different natural teeth, and the operator can select the corresponding gingival penetration contour of the scanning shell 2 by observing the edentulous area;

[0022] The scanning shell 2 is provided with a scanning positioning part for positioning the implant scanning, and the scanning positioning part includes an arcuate section 21 opened on the end face of the scanning shell 2, and a state identification surface for acquiring intraoral data is provided on the arcuate section 21, and at least one arcuate section 21 is provided; it is processed by grooving the top of the scanning shell 2, and at the same time, according to the scanning body scanning data, the larger the plane of the healing top surface is, the more conducive it is to scanning, and the larger the surface is, the easier it is to scan clear lines. Therefore, in actual use, different numbers of arcuate sections 21 can be set according to the healing base and the scanning mold rod integrated device of different diameters and lengths, and multiple arcuate sections 21 are also arranged at intervals around the axis of the healing body 1;

[0023] The scanning shell 2 and the upper healing base 11 are connected to each other and are provided with lead holes 3. The lead holes 3 can be provided in several groups according to the needs. When the patient needs it, the wire can be passed through the lead holes 3, and then the movement of the gums can be driven by pulling the wires to reduce the exposure rate of the wound. Especially when the base is smaller than the wound, the wound can be closed by sutures and light-cured fluid resin can be used to isolate the wound from the oral environment. This can also promote the formation of gingival papillae, which is more in line with the overall aesthetic requirements.

[0024] The integrated healing abutment and scanning impression rod device also includes a mating rod 4, the bottom of the mating rod 4 is a screw 41, the screw 41 is threadedly connected to the upper healing abutment 11, and the top of the mating rod 4 is a hexagonal nut 42; when the integrated healing abutment and scanning impression rod device needs to be fixed to the implant, the tightening force by manual rotation is insufficient, and at this time, the screw 41 of the mating rod 4 can be threadedly connected to the internal thread of the upper healing abutment 11, and then locked by the hexagonal nut 42 on the top with a hexagonal wrench.

[0025] The working principle of the above-mentioned healing base and scanning impression rod integrated device is as follows:

[0026] In the case of immediate implantation (implantation immediately after tooth extraction), after tooth extraction, prepare a hole in the alveolar bone, implant the artificial implant, install the healing base, make the implant pass through the gums (if necessary, the local gums can be appropriately relieved), use sutures to suture the base to the surrounding gums. If the base cannot be completely covered or the pulling force is too large, light-cured fluid resin can be attached to the sutures to close the wound. Wait for the soft tissue to take shape. After the soft tissue is formed, wait for the repair stage, use an intraoral scanner for digital scanning or take a mold with a mold rod, and after making traditional dentures, the doctor takes out this product, installs the denture, and completes the final repair.
