Description

Manufacturing method of digital movable denture module

The invention relates to a full-mouth movable denture, especially a digital movable denture module, and a manufacturing method of the digital movable denture module.

The objects of full dentures are mostly older patients, but there are also some people who need to make full dentures because of severe periodontal disease in their entire mouths, resulting in full dentures.

When a patient comes to see a doctor and needs to make a full denture, the patient hopes that the manufacturing time of the denture can be completed sooner, without too many visits, and the patient also hopes that the new movable denture can restore its complete occlusal function and Beautiful function.

However, the ease of use of full dentures is not only related to the patient's personal conditions, and the production process also needs to be carefully and cautiously, so that the finished dentures can have ideal results.

With the current technology for manufacturing dentures, it usually takes about five to six appointments to obtain the finished dentures for the production of full dentures. If you return to the clinic once a week, it will take nearly two months to get the dentures.

The general production process of full-mouth dentures is:

First appointment: Usually at the first appointment, the dentist will do a preliminary examination of the condition of the mouth, including the degree of wound healing after tooth extraction, the degree of edentulous ridge absorption, and the condition of the soft tissues in the mouth. And whether the patient has other diseases or taking medication. If the patient has been accustomed to wearing full dentures before, at this time, the patient’s previous adaptation to wearing dentures is also important to the dentist. Basis. After the oral examination is completed, a rough tooth model (taking the alginate impression material to obtain the upper/lower jaw model) needs to be printed, and the dental tray is made for the patient in the dental laboratory.

The second appointment: the production of the precision model of the mouth is to take the model with the exclusive dental tray, and then enter the dental laboratory to make the wax bank. Because full dentures are maintained in the oral cavity by the force similar to the suction cup between soft tissue and saliva, the most important purpose of this appointment is to accurately determine the soft tissue condition of any kind of exercise in the mouth. The results of this time will also affect the maintenance of full dentures in the mouth, so it will take more time during this appointment, and you must cooperate with the doctor to do some oral exercises.

The third appointment: the preparation of the intraoral occlusal wax embankment and the acquisition of the aesthetic vertical height. At this time, there may be errors and can not be found in time, and then enter the dental laboratory for tooth arrangement.

The fourth appointment: try on the arranged teeth in the mouth, you can find the problem, and take the record again, go to the dental laboratory to adjust the tooth arrangement, and make the final confirmation. Depending on the situation, some dentists will divide this step into two or more appointments until the patient.

Fifth appointment: the denture is completed. After the adjustment of the tissue surface and the adjustment of the occlusion, the patient can bring the dentures back, but if more adjustments are still needed, there may be one or two more appointments to allow the patient to bring the finished dentures back.

Please refer to FIG. 1. It is worth mentioning that when the tooth falls on the gum 11, the gum 11 will cover the alveolar bone 12, and the shape and position of the alveolar bone 12 cannot be known from the appearance of the gum 11. Generally speaking, the shape of the bottom surface of the dental seat 14 of the artificial tooth 13 only conforms to the appearance of the gum 11. When the artificial tooth 13 arranged on the dental seat 14 engages with other teeth, the pressure exerted by the dental seat 14 on the gum 11 will press against the alveolar bone. 12, it will make the gums 11 appear uncomfortable areas, and even a painful sensation. Because the current full-port 3D scan can only scan the shape of the surface of the gingiva 11, and cannot know the position of the alveolar bone 12, it is not possible to use the full-port 3D scan data to make finished dentures.

In order to improve the discomfort of wearing dentures mentioned above, it is necessary for the patient to try on the dentures and adjust the dentures repeatedly. However, the current dentures are 3D printed products, which are hard materials. After obtaining the patient’s response, the dental technician resets the shape parameters of the computer to produce a new denture try-on for the patient to try. The parameter adjustment and 3D printing must take time, so the patient must return to the clinic several times to test the denture. Wear it, and finally get a finished denture that fits.

Although the conventional technology has revealed a manufacturing technology for full dentures, it still has the following shortcomings in actual use:

1. A waste of time:

Although the shape of the gums can be obtained during the mold-taking operation, because there is alveolar bone in the gums, each person's alveolar bone is different, so it is necessary to try on the denture many times. At one time, it takes more than a month for the patient to obtain dentures, which is a waste of time for the doctor and the patient.

2. A large amount of waste is generated:

Every time a patient tries on a denture try-on, it is a 3D printed product and cannot be recycled. Therefore, every time a patient tries on a denture try-on, the denture try-on must be discarded, and the patient also needs to dispose of it multiple times Return to the clinic to try on the denture try-on, so a lot of waste will be generated before the finished denture is finished.

3. The product has defects:

Because the patient has to come back to the clinic several times to try on the dentures, it takes nearly two months to obtain the dentures. Some patients can't bear the temper and rashly ask the doctor to make the final dentures. The finished dentures are not suitable for the patients. , The product has defects.

Therefore, how to reduce the number of patient return visits and obtain fully adapted denture products is an urgent goal for relevant technicians.

In view of this, the purpose of the present invention is to provide a method for manufacturing a digital movable denture module.
