Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a chairside digital immediate load-bearing temporary denture manufacturing method. Background Art

[0002] In the immediate implant-loaded restoration of the edentulous jaw, the absolute rigidity of the temporary denture is very important for the healing and success of the implant. There are two conventional production methods.

[0003] 1. Traditional denture production methods include: 1. Implanting the implant into the patient's mouth and installing the composite base; 2. Installing the window impression rod and rigidly connecting it; 3. Taking the impression and obtaining the bite record; 4. Maxillary frame and casting the model; 5. Installing the temporary base on the model, arranging the teeth and filling with glue, grinding and polishing; 6. Wearing it in the mouth.

[0004] 2. Digital production methods include: 1. Implanting the implant and installing the scanning rod in the patient's mouth; 2. Scanning the dentition, soft tissue and occlusal relationship in the mouth; 3. Cutting personalized composite abutments and digitally designing and cutting to produce temporary dentures; 4. Cutting, grinding and polishing; 5. Wearing in the mouth.

[0005] Both of the above two production methods have certain shortcomings:

[0006] Traditional denture production methods involve too many additional operations, such as absolutely rigidly connecting the transfer rod, making personalized trays, and making plaster rigid connections for intraoral verification of the remade plaster models. Otherwise, the accuracy requirements cannot be met, the production is more complicated, the intraoral operation time is longer, and it is easy to cause certain discomfort to the patient;

[0007] The digital production method is complicated to operate and can easily result in inaccurate dentures that cannot be worn. This is mainly reflected in the small size of the scanning rod, which is prone to errors in data acquisition. Digital acquisition, that is, the scanning instrument obtains data in a single way and requires repeated comparison with the patient's oral condition. Summary of the invention

[0008] The object of the present invention is to provide a chairside digital immediate load temporary denture production method to solve the problems raised in the above background technology.

[0009] The technical solution of the present invention is: a chairside digital immediate load temporary denture production method, comprising the following steps:

[0010] Step 1: implant the implant in the patient's mouth, install the composite abutment, and install a temporary titanium barrel on the composite abutment;

[0011] Step 2: The titanium barrel is rigidly supported by an adjustable rigid component and filled with self-curing resin, and after trimming, it is used as a temporary denture rigid bracket;

[0012] Step 3: Perform intraoral scanning to obtain intraoral information data;

[0013] Step 4: Import the intraoral information data into the full denture design software to design the bite reconstruction, and make a full denture that matches the patient's intraoral data information;

[0014] Step 5: Use intraoral screws to fix the full denture to the titanium barrel, and fill it with self-curing resin to bond the full denture to the titanium barrel;

[0015] Step 6: After curing, adjust the bite and gum base, and polish to complete the denture wearing.

[0016] As a further supplement to this solution, the intraoral information data in step three includes: temporary denture rigid bracket information data, gum morphology information data, and opposing teeth information data.

[0017] As a further supplement to this solution, step three also includes using an electronic face bow to record occlusal information data and mandibular motion range information data.

[0018] As a further supplement to this plan, in step 4, the design of jaw reconstruction includes occlusal functional movement design, gingival fitting temporary denture rigid bracket design, and gingival entry direction cutting design, and finally a full denture that matches the patient's intraoral information data is produced.

[0019] As a further supplement to this solution, the temporary denture rigid bracket information data in step 3 also includes corresponding titanium barrel position opening data;

[0020] In step 4, the complete denture is designed and produced with reference to the opening of the corresponding titanium barrel position.

[0021] As a further supplement to this solution, step six includes: after curing, fine-tuning the bite jaw according to the actual occlusal conditions of the patient so that the occlusal and gingival forces are adapted, and performing local adaptive polishing of the full denture.

[0022] As a further supplement to the present solution, the adjustable rigid component adopts a multi-size rigid support component that can adapt to the complete denture, and the adjustable rigid component is sleeved and supported between multiple titanium barrels.

[0023] As a further supplement to the present solution, the adjustable rigid component is a continuous open annular support structure, and the adjustable rigid component can be broken for use.

[0024] As a further supplement to this solution, one end of the titanium barrel is fixed to the composite base, and a reserved hole for connecting an intraoral screw is reserved at one end of the titanium barrel away from the composite base.

[0025] As a further improvement of the present solution, the adjustable rigid component adopts a comb structure in the middle and a supporting structure of a ring structure on both sides. The comb structure of the adjustable rigid component is arranged at an inclined angle to the ring.

[0026] The present invention provides a chairside digital immediate load temporary denture production method through improvement, which has the following improvements and advantages compared with the prior art:

[0027] First, the present invention adopts a semi-digital method for making immediate load-bearing temporary dentures. Compared with the traditional denture making method, the method has a simple process, eliminates the steps of taking a mold and remaking a plaster, accurately adapts the data, and the finished product has high adaptability and high precision. In addition, by directly using an intraoral rigid bracket as a denture bearing and adhesive receptor, multiple intraoral verification operations are avoided, the making process is short, and the making is simple and quick.

[0028] In addition, compared with the pure digital production method: the use of finished original composite abutments has high precision and the process is simpler and more accurate. The temporary dentures digitally produced by this method can compensate for the errors in denture production by bonding with the rigid bracket of the temporary denture, thereby achieving faster production and better fit and precision of the finished product. At the same time, it reduces the high production cost caused by high-precision requirements and is suitable for comprehensive promotion.

[0029] Secondly, the present invention uses a titanium barrel and an adjustable rigid component to rigidly support the titanium barrel, and cooperates with the use of self-curing resin to obtain a temporary denture rigid bracket, and improves the original technical route: taking a working model - transferring to make a plaster model - making a denture on the plaster model - wearing it intraorally, to the current technical route: making a rigid intraoral connecting component - fitting a prefabricated denture outside the mouth - wearing it intraorally, which simplifies the steps of remaking the model, eliminates the errors caused by simplifying the remaking model, and reduces the intraoral operation time, making the production faster and more convenient. In addition, it can also flexibly adapt to the fixing requirements of different spacings, and the actual use effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present invention provides a chairside digital immediate load temporary denture production method through improvement. The technical solution of the present invention is:

[0040] Example 1

[0041] like Figure 1-Figure 3 As shown, a chairside digital immediate loading temporary denture production method comprises the following steps:

[0042] Step 1: implant the implant in the patient's mouth, install the composite abutment, and install a temporary titanium barrel on the composite abutment. One end of the titanium barrel is fixed to the composite abutment, and a reserved hole for connecting the intraoral screw is reserved at the end of the titanium barrel away from the composite abutment;

[0043] Step 2: The titanium barrel is rigidly supported by an adjustable rigid component. The adjustable rigid component adopts a multi-size rigid support component that can adapt to full dentures. The adjustable rigid component is set and supported between multiple titanium barrels, and filled with self-curing resin. After trimming, it serves as a temporary denture rigid bracket;

[0044] Step 3: Perform an intraoral scan to obtain intraoral information data, including temporary denture rigid bracket information data, gum morphology information data, opposing teeth information data, corresponding titanium barrel position opening data, and use an electronic face bow to record occlusal information data and mandibular motion range information data;

[0045] Step 4: Import the intraoral information data into the full denture design software to design the occlusal reconstruction, including the occlusal function movement design, the gingival fitting temporary denture rigid bracket design, the gingival insertion direction cutting design, and refer to the corresponding titanium barrel position opening to make a full denture that matches the patient's intraoral data information;

[0046] Step 5: Use intraoral screws to fix the full denture to the titanium barrel, and fill it with self-curing resin to bond the full denture to the titanium barrel;

[0047] Step 6: Adjust the bite and gingival base after curing. After curing, fine-tune the bite according to the actual bite of the patient to make the bite and gingival base forces match, and perform local adaptive polishing of the full denture to complete the denture wearing.

[0048] The above method is used to make an immediate load-bearing temporary denture. Compared with the traditional denture production method, the method has a simple process, eliminates the steps of taking a mold and remaking a plaster, accurately adapts the data, and the finished product has high adaptability and high precision. In addition, by directly using an intraoral rigid bracket as a denture bearing and adhesive receptor, multiple intraoral verification operations are avoided, the production process is short, and the production is simple and fast.

[0049] In addition, compared with the pure digital production method: the use of finished original composite abutments has high precision and the process is simpler and more accurate. The temporary dentures digitally produced by this method are made by bonding with the rigid bracket of the temporary denture, which can compensate for the errors in denture production, thereby achieving faster production and better fit and precision of the finished product. At the same time, it reduces the high production cost caused by high-precision requirements and is suitable for comprehensive promotion.

[0050] The method for making a full denture that is compatible with the patient's oral data information referred to in step 4 adopts a method commonly used in the prior art and applicable to the present embodiment, such as using resin or heat (self) solidifying methyl methacrylate plastic to make a full denture. Specifically, a 3D printing device (or other commonly used manufacturing equipment in the prior art) is used to input a full denture design software into the 3D printing device. The full denture manufacturing plan designed according to the patient's oral information data is directly 3D printed using resin or heat (self) solidifying methyl methacrylate plastic, and the finished full denture can be quickly obtained. The finished product has high precision and fast manufacturing speed, which meets the manufacturing requirements of immediate load-bearing temporary dentures.

[0051] Furthermore, the adjustable rigid component is a continuous open annular support structure, and the adjustable rigid component can be broken for use, such as Figure 4 As shown, it includes a hoop plate 1, and the hoop plates 1 are provided in plurality and divided into two groups. The two groups of hoop plates 1 are equal in number and arranged opposite to each other, and the plurality of hoop plates 1 in each group are arranged in rows and are equidistantly arranged in sequence;

[0052] A connector 2 is provided between every two adjacent hoop plates 1. A plurality of connectors 2 are provided and are respectively located between a plurality of adjacent hoop plates 1. Both sides of the connector 2 are respectively integrally formed with one end of two adjacent hoop plates 1 that are close to each other.

[0053] A plurality of reinforcing connecting rods 3 are fixed between the plurality of connecting heads 2 connecting the two sets of hoop plates 1. The plurality of reinforcing connecting rods 3 correspond to the plurality of connecting heads 2 respectively, and the number of reinforcing connecting rods 3 is less than one quarter of the number of connecting heads 2.

[0054] Among them, the connecting ends of other connecting heads 2 that are not connected to the reinforcing connecting rod 3 and the hoop plate 1 are formed with breaking grooves.

[0055] Based on the above structure, when a rigid connector is needed to rigidly support the transfer repair rod, firstly, the distance between the two titanium barrels is measured by an intraoral caliper, and then the appropriate spacing of the hoop plates 1 is selected by comparing the spacing, and the excess hoop plates 1 are broken according to the breaking grooves, so that the applicable rigid connector can be quickly obtained, and the hoop plates 1 are set on the corresponding transfer repair rod, and then the rigid fixation of the intraoral repair base can be completed by filling with self-curing resin. This method completely changes the original production technology route:

[0056] The original technical route: taking impressions from the working model - transferring to make a plaster model - making dentures on the plaster model - wearing them intraorally, is improved to the current technical route: making rigid intraoral connecting parts - fitting prefabricated dentures outside the mouth - wearing them intraorally. This simplifies the steps of making the model, eliminates the errors caused by simplifying the model, reduces the intraoral operation time, and makes the production faster and more convenient. In addition, it can flexibly adapt to the fixing requirements of different spacings, and the actual use effect is better.

[0057] Example 2

[0058] The present invention also provides another chairside digital immediate load temporary denture production method, which is based on Example 1 and is different from Example 1 in that:

[0059] The adjustable rigid component is a supporting structure with a comb structure in the middle and ring structures on both sides. The comb structure of the adjustable rigid component is arranged at an inclined angle with the ring, such as Figure 5 As shown, it includes a connecting ring 5, one side of which is connected to a rigid card comb 4, and the rigid card comb 4 is tilted and forms an angle with the plane side wall of the connecting ring 5;

[0060] The rigid card comb 4 includes a long rod base, on which a plurality of card columns perpendicular to the long rod base are fixedly formed, and the plurality of card columns are evenly distributed along the length direction of the long rod base;

[0061] When the rigid clamping combs 4 of the two rigid connectors are clamped together, the connecting rings 5 ​​of the two rigid connectors have the same posture.

[0062] Based on the above structure, the rigid card combs 4 of the two rigid connectors are mutually clamped, so that the two rigid connectors form a rigid support body with adjustable length, and the two connecting rings 5 ​​are respectively mounted on the repair base of the transfer rod repair structure, thereby achieving the purpose of rigid connection and rigid support. At the same time, by adjusting the number of comb teeth clamped by the two rigid card combs 4, the overall length of the rigid support body composed of the two rigid connectors can be adjusted, so as to adapt to the transfer rod repair structure with different spacings, fully meet the rigid connection requirements with variable spacings, and the actual use effect is excellent.

[0063] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
