Description

Movable denture module and manufacturing method thereof

Technical Field

The invention relates to a full-mouth movable denture, in particular to a movable denture module and a manufacturing method thereof.

Background

The whole denture is usually intended for older patients, but some people have to make whole dentures because of complete severe periodontal disease and complete lack of teeth.

When a patient comes for a visit and needs to make a full denture, the patient wants the time for manufacturing the denture to be completed to be quicker, the number of return visits is not needed to be increased, and the patient also wants a new movable denture to recover the complete occlusion function and the aesthetic function.

However, the good use of the whole denture is not only related to the personal condition of the patient, but also the process of making the denture needs to be careful, and the denture can have ideal results.

With current techniques for manufacturing dental prostheses, the manufacture of a full denture generally requires about five to six visits to obtain a finished denture, and if a visit is made once a week, it takes approximately two months to obtain a denture.

The general manufacturing process of the full mouth type false tooth comprises the following steps:

first appointment: typically, at the first appointment, the dentist will make an initial examination of the conditions in the mouth, including the degree of wound healing after tooth extraction, the degree of non-ridge absorption, the condition of the soft tissues in the mouth, and whether the patient has other illnesses or medical conditions. If the patient has a habit of wearing a full denture before, the adaptation situation of wearing the denture before the patient is also an important basis for the dentist. After the oral examination, a rough tooth model (alginate impression material is used to obtain the upper/lower jaw model) is printed and a dental tray for a specific patient is manufactured by the dental skill.

And (3) second appointment: the making of the precise model in mouth is to take out the special denture and then to enter the dental skill to make the wax dike. Because the whole denture is maintained in the mouth by the force between the soft tissue and the saliva acting like a suction cup, the precise impression of the internal soft tissue condition in any kind of movement is the most important purpose of this appointment. The result of this time will also affect the holding power of the whole denture in the mouth, so it takes much time to make this appointment and some oral movements are required to be performed in cooperation with the physician.

And (3) performing third appointment: the making of the intraoral occlusion wax dike and the obtaining of the beautiful vertical height can be mistaken and cannot be found in time, and then the teeth are arranged by entering the dental skill.

The fourth appointment: try on the arranged teeth in the mouth, find problems, retrieve the records again, adjust the arrangement of the teeth in the dental skill and finally determine the teeth. Some dentists divide this procedure into two or more appointments according to different conditions until patients.

And (4) fifth appointment: and finishing the manufacture of the false teeth. After the adjustment of the tissue plane and the occlusal adjustment, the patient may return the denture, but if more adjustments are still needed, perhaps one or more additional appointments may be made to return the finished denture.

Referring to fig. 1, it is worth mentioning that when a tooth falls off on the gum 11, the gum 11 covers the alveolar bone 12, and the shape and position of the alveolar bone 12 are not known from the appearance of the gum 11. Generally, the bottom surface of the dental seat 14 of the dental prosthesis 13 is shaped to conform to the appearance of the gum 11, and when the dental prosthesis 13 disposed on the dental seat 14 is engaged with other teeth, the pressure applied to the gum 11 by the dental seat 14 is pressed against the alveolar bone 12, which may cause discomfort or even pain to the gum 11. Since the full-mouth 3D scan can only scan the shape of the surface of the gum 11 and cannot know the position of the alveolar bone 12, the finished denture cannot be manufactured by only the data of the full-mouth 3D scan.

In order to improve the discomfort caused by wearing the false teeth, the patient must try on the false teeth trial product repeatedly and adjust the false teeth trial product repeatedly, however, the current false teeth trial product is a 3D printed product, which is a hard material, the dental technician must obtain the reaction of the patient and reset the shape parameters to the computer, and then a new false teeth trial product is generated to try on the patient, the parameter adjustment and 3D printing must take time, so the patient must make a plurality of back visits to try on the false teeth, and finally obtain the adapted false teeth product.

Although the known art discloses a technique for manufacturing a full denture, the following disadvantages are still present in practice:

firstly, wasting time:

although the shape of the gum can be obtained in the operation of taking the model, because the alveolar bone exists in the gum and the alveolar bone of each person is different, the artificial tooth must be tried on many times, for example, the number of times of return visits must be more than five times, and the time for obtaining the artificial tooth by the patient exceeds one month, which wastes a lot of time for doctors and patients.

Secondly, generating a large amount of waste:

the denture try-on article that the disease tried on every time is 3D prints the product, can not recycle, therefore every time the disease after trying on denture try-on article, denture try-on article just must be abandoned, the disease also need to examine denture try-on article many times back, consequently can produce a large amount of discarded objects before accomplishing the denture finished product.

Thirdly, generating defects in the product:

because the patient must go back to try on the denture for many times, the time for obtaining the denture is about two months, some patients have poor survivability, the doctor is requested to manufacture the final denture with a high draft, the finished denture is not suitable for the patient, and the product has flaws.

Therefore, how to reduce the number of patient return visits and obtain a fully-fitted denture product is an urgent task for those skilled in the art.

It may be necessary to extract wax and arrange teeth in the early stage, but the prior art may store the shape data of the first gum 211 and the second gum 212 in a computer unit (not shown) by means of 3D scanning of the first mold 22 and the second mold 23, wherein the computer unit may have an automatic tooth arrangement program to calculate the thickness of the denture, the center line of the denture, and further, the automatic tooth arrangement, and the dental technician may also operate the computer to adjust various parameters to plan the whole denture. In practice, other gingival modeling techniques may be used, and should not be limited thereto.

In the first manufacturing step 902, a first tooth module 41 and a second tooth module 42 are manufactured according to the shape of the first mold 22. Preferably, the first toothed module 41 and the second toothed module 42 are manufactured from the computer unit by means of 3D printing. In practical implementation, the first tooth module 41 and the second tooth module 42 can be made in other manners, which should not be limited thereto.

Referring to fig. 5, the first tooth module 41 includes a generally U-shaped first body 411, a first engaging portion 412 disposed on the first body 411, two first setting portions 413 disposed on the first body 411 and opposite to the first engaging portion 412, two first engaging portions 414 separately disposed on the two first setting portions 413, two first arrangement tooth portions 415 disposed on the two first engaging portions 414, and a first positioning tooth portion 416 disposed on the first body 411 and connected to the two first setting portions 413, wherein the first engaging portion 412 has a concave shape matching with the convex shape of the first gum 211.

The second tooth module 42 has a generally U-shaped second body 421, a second engaging portion 422 disposed on the second body 421, two second setting portions 423 disposed on the second body 421 and opposite to the second engaging portion 422, two second engaging portions 424 detachably disposed on the second setting portions 423, two second arrangement tooth portions 425 disposed on the second engaging portions 424, and a second positioning tooth portion 426 disposed on the second body 421 and connected to the second setting portions 423, wherein the second engaging portion 422 has an inner concave shape matching with the outer convex shape of the second gum 212.

In the first preferred embodiment, the first positioning tooth portion 416 is a plurality of upper incisors and upper canines disposed on the side of the upper incisors, the second first arrangement teeth 415 is a plurality of upper molars, the second positioning tooth portion 426 is a plurality of lower incisors and lower canines disposed on the side of the lower incisors, the second arrangement teeth 425 is a plurality of lower molars, the two first arrangement portions 413 and the two second arrangement portions 423 are planar, and the top surfaces of the first tooth connection portions 414 and the bottom surfaces of the second tooth connection portions 424 are planar.

Preferably, the first setting portion 413 and the first engaging portion 414 are connected by wax, and the second setting portion 423 and the second engaging portion 424 are connected by wax, and the wax is hard at room temperature.

Referring to fig. 6, in the trying step 904, the person tries to wear the first tooth module 41 and the second tooth module 42 and engages them to feed back the problem of the first tooth module 41 and the second tooth module 42.

Although in the preliminary mold-taking step 901, the concave shape of the first engaging portion 412 matches with the convex shape of the first gum 211, the concave shape of the second engaging portion 422 matches with the convex shape of the second gum 212. However, the gum has alveolar bone, which causes uneven pressure. In addition, the teeth of the first tooth module 41 and the second tooth module 42 may bite into the tongue or the mouth flesh, and the person can feedback the problem of the first tooth module 41 and the second tooth module 42.

In the adjusting step 905, the dental technician adjusts the relative position, relative distance, and relative angle between the first engaging portion 414 and the first installation portion 413, and adjusts the relative position, relative distance, and relative angle between the second engaging portion 424 and the second installation portion 423 according to the feedback problem of the human. Since wax is melted after being heated, the first tooth module 41 and the second tooth module 42 can be placed in hot water, so that a dental technician can adjust the relative positions of the first tooth arrangement 415 and the first body 411 and the second tooth arrangement 425 and the second body 421.

It should be noted that, since the present invention has the first tooth portion 414 detachably connected to the first body 411 and the second tooth portion 424 detachably connected to the second body 421, a dental technician can adjust the relative positions of the first tooth arrangement portion 415 and the first body 411 and the relative positions of the second tooth arrangement portion 425 and the second body 421 on site. The person does not need to visit several times to try on different dentures.

The inventor has clarified that the incisors cut food, the canines tear food, and the molars grind food, and besides, the molars provide a better biting and positioning effect, and the surfaces of the molars have concave and convex shapes, so that the positioning relationship between the first tooth module 41 and the second tooth module 42 can be determined by the biting of the upper and lower molars.

With the first tooth module 41 and the second tooth module 42 positioned, the first engaging portion 412 of the first tooth module 41 applies pressure to the first gum 211, the second engaging portion 422 of the second tooth module 42 applies pressure to the second gum 212, the person can feel uncomfortable position of the first gum 211 or the second gum 212 for feedback to the dental technician for adjustment, and the fitting step 904 and the adjusting step 905 are repeated, so that the person does not feel uncomfortable when the person bites in the mouth, and at this time, the first gum 211 and the second gum 212 of the person are completely fitted to the first tooth module 41 and the second tooth module 42.

In addition, the dental technician may also ask the person to perform various tests such as pronunciation test, aesthetic adjustment, chewing test, horizontal position, vertical position, etc. since the above test items are known in the art and will not be described in detail herein, in practice, a layer of impression material may be further coated on the surface of the denture to let the person perform oral cavity movement, smiling or laughing movement to shape the impression material for obtaining the exclusive denture shape of the person.

Referring to fig. 7, in the second manufacturing step 907, when the person completely fits the first tooth module 41, the computer unit manufactures a first artificial tooth body 24 according to the shape of the first tooth module 41 by using the stereolithography technique, and manufactures a second artificial tooth body 25 according to the shape of the second tooth module 42 by using the stereolithography technique.

Preferably, the computer unit can obtain the shapes of the first tooth module 41 and the second tooth module 42 by using a 3D scanning technique, and manufacture the first artificial tooth body 24 and the second artificial tooth body 25 by using a 3D printing technique, wherein the first artificial tooth body 24 and the second artificial tooth body 25 are artificial dentures, the gum is bright red, the teeth are white, and the upper and lower jaws can be supported to a normal height by wearing the first artificial tooth body 24 and the second artificial tooth body 25, thereby achieving the effects of beauty and food chewing.

In the first preferred embodiment, the person performs the preliminary mold-taking step 901 at the first visit, then the dental technician performs the first manufacturing step 902 and the temporary connection step 903 to complete the first tooth module 41 and the second tooth module 42 and wait for the second visit of the person, performs the trying step 904, the adjusting step 905, and the repeating step 906 at the second visit so that the person can completely fit the first tooth module 41 and the second tooth module 42, then the dental technician performs the second manufacturing step 907 to manufacture the first dental prosthesis 24 and the second dental prosthesis 25 and wait for the third visit of the person, and can obtain the first dental prosthesis 24 and the second dental prosthesis 25 fit with the first gum 211 and the second gum 212 at the third visit of the person, so the present invention only needs to perform three visits, such as one visit in a week, the invention enables the person to obtain the movable denture module without needing to take one month, compared with the early manufacture of the denture, the invention effectively shortens the time for obtaining the denture.

The first preset teeth 27 have upper incisors 271, upper canine teeth 272, and upper setting portions 273 connected to the upper incisors 271 and the upper canine teeth 272, and the second preset teeth 28 have lower incisors 281, lower canine teeth 282, and lower setting portions 283 connected to the lower incisors 281 and the lower canine teeth 282. In practice, the tooth arrangement of the first predetermined tooth 27 and the second predetermined tooth 28 should not be limited thereto.

The first mold 22 is disposed on the top surface of the first predetermined tooth 27, and the second mold 23 is disposed on the bottom surface of the second predetermined tooth 28, preferably, the top surface of the upper setting portion 273 has a groove for receiving the first mold 22, and the bottom surface of the lower setting portion 283 has a groove for receiving the second mold 23.

When the person engages the first mold 22 with the second mold 23, a dental technician takes the appearance of the first predetermined teeth 27 and the second predetermined teeth 28 as a reference for center recording, which can mark the center, level, and occlusal plane positions, and make the first mold 22 and the second mold 23 able to obtain the gum shape of the person. In practice, only the first predetermined tooth 27 or the second predetermined tooth 28 can be used, but not limited thereto.

Referring to fig. 12, a fifth preferred embodiment of the removable dental prosthesis module of the present invention is substantially the same as the first preferred embodiment, and the same points are not described in detail, except that the method of manufacturing the removable dental prosthesis module of the present invention further comprises a precise mold extraction step 908 between the repeating step 906 and the second manufacturing step 907, which can obtain the shape of the oral cavity by full mouth scanning or impression material.

The full-mouth scanning is a 3D computed tomography scanner, which can surround the head of a person, and can display the shape of the oral cavity of the person on a screen in a 3D manner through program operation.

When the dental technician accurately obtains the mouth shape and also obtains the first tooth module 41 and the second tooth module 42, the second manufacturing step 907 can be entered to manufacture the first artificial tooth body 24 and the second artificial tooth body 25, because the accurate mold-taking step 908 is performed in the second manufacturing step 907, the dental technician can further determine the mouth shape of the person so that the first artificial tooth body 24 and the second artificial tooth body 25 can be manufactured to be more adapted to the mouth of the person.

From the above description, it can be seen that the method for manufacturing a removable dental prosthesis module according to the present invention has the following effects:

firstly, rapidly obtaining the false teeth:

compared with the early denture manufacturing technology, the movable denture module manufacturing method can quickly acquire the denture only by three return visits of the personnel.

Secondly, reducing waste:

the first tooth module 41 is provided with a first setting part 413, so that a dental technician can adjust the relative position of the first arrangement tooth group and the first main body 411 on site, and does not need to manufacture a plurality of false teeth for trial wearing, thereby effectively reducing the amount of waste.

Thirdly, the false teeth are completely matched:

the method for manufacturing the removable dental prosthesis module of the present invention adjusts the relative positions of the first arrangement tooth portion 415 and the first body 411 and the relative positions of the second arrangement tooth portion 425 and the second body 421 in one visit, and obtains the first tooth module 41 and the second tooth module 42 which are completely fitted with the first gum 211 and the second gum 212, so that the person does not lose patience due to multiple visits, and further obtains an unsuitable dental prosthesis.

In summary, in the first manufacturing step 902, the dental technician manufactures the first tooth module 41 having the first setting portion 413, so that the trying step 904, the adjusting step 905, and the repeating step 906 can be completed in one visit of the person, and the dental technician manufactures the first and second prosthetic teeth 24 and 25 adapted to the first and second gums 211 and 212 of the person, thereby effectively reducing the manufacturing time of the movable prosthetic tooth module and reducing the waste in manufacturing the movable prosthetic tooth module, and thus the object of the present invention can be achieved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention, and should not be taken as limiting the scope of the invention, which is defined by the appended claims.
