Description

Film pressing equipment, film pressing method and one-stop type dental socket production system

Technical Field

The invention belongs to the technical field of medical appliances, and particularly relates to a tooth correction technology, in particular to a film pressing device, a film pressing method and a one-stop dental floss production system.

Background

In the prior art of dental floss preparation, the current common manufacturing method is manual or semi-automatic. The whole manufacturing process comprises the working procedures of obtaining a digital model in a mouth of a patient, 3D printing the dental model, cleaning the dental model, solidifying the dental model, pressing a film, manually removing the film, cutting, polishing, cleaning a dental socket, checking, packaging and the like. And the semi-automatic manufacturing is only realized by some procedures, and the two manufacturing modes are completed by manual participation.

The existing dental model is cleaned by manually using organic solvents such as alcohol as cleaning liquid for ultrasonic cleaning, and for viscous resin materials which cannot be cleaned by an ultrasonic cleaning method, the viscous resin materials are cleaned manually by using solvents and then dried. Firstly, residual 3D printing resin and volatile organic solvent have great peculiar smell, and the residual resin and the solvent are directly or indirectly contacted, so that people are damaged. Secondly, the manual cleaning work is inefficient and cannot improve productivity on a large scale. And moreover, the cleaning solution is large in use amount, and the direct discharge causes serious environmental pollution, so that the recovery and reutilization of the cleaning solution are also the problems to be solved urgently.

In the film pressing process, high-degree manual participation exists. The operator selects the diaphragm, then puts the diaphragm into the heating platform and heats, then places the dental model on the film pressing platform, finally withholds the heated diaphragm on the film pressing platform to implement vacuum film pressing, and finally achieves the film pressing effect. However, there is a problem in the operation, firstly, since the types of dental braces are various, the types of diaphragms selected for different types of dental braces are also different, for example, the thickness of the diaphragm required by the accessory template is 0.5mm, the thickness of the diaphragm required by the appliance is 0.75mm, and the thickness of the diaphragm required by the retainer is 1mm; in addition, the membrane is made of a high polymer material, the currently commonly used membrane is PETG or TPU, and the like, and in the process of selecting manually, due to the fact that the membrane is more in variety and larger in human factors, the operation error is easy to occur, and the membrane is selected by mistake, so that the dental floss is directly unqualified. Secondly, the manual film pressing work efficiency is low, and the productivity cannot be improved on a large scale. And the membrane in the membrane pressing process is preheated at high temperature, so that the requirement on the proficiency of operators is high, and the potential risk of scalding is easy to occur.

In the process of demoulding, the method adopted at present is also manual operation, firstly, the dental model with the dental sleeve after the film pressing is cut off along the edge of the dental model, and then the demoulding is carried out. Because the dental floss is pressed on the dental floss model with uneven surface shape by adopting a hot pressing mode, the dental floss is generally difficult to be peeled off from the dental floss model. In order to prevent the dental mouthpiece from deforming in the demolding process, a great amount of pre-post training is needed for operators to identify demolding points and master demolding force and operation skills. The operation proficiency and state stability of the on-duty personnel can influence the stripping operation quality and the tooth socket quality. The manual operation can bring the dental floss pollution, increase follow-up cleaning operation burden and corresponding cost. In the automatic production process of the dental braces, the step of removing the dental braces from the dental model is the most difficult stage in the whole production process, and the automatic operation is not realized at present.

In the cutting process, the current method is manual operation or automatic cutting, and the common mode of automatic cutting is laser cutting or mechanical cutting. Finally, the cut tooth socket is cleaned and packaged manually, so that the labor intensity is high and the production efficiency is low.

In the existing production process of dental braces, the operation method is mostly manual operation or semi-automatic operation, the whole assembly line occupies large production space, and many participants are involved, so that the efficiency is low in the large-scale production process, and resources are wasted.

The traditional invisible correction mode is generally that after diagnosis and scheme design are carried out by doctors, correction schemes are sent to manufacturers for dental socket manufacture. The manufacturer receives orders, arranges and produces, and sends finished dental braces to doctors or corresponding clinics after a certain time. And then the doctor informs the patient to get the dental mouthpiece, and finally reaches the hand of the patient to start wearing treatment. The traditional flow can be summarized into a custom-made-manufactured-sent-picked delivery mode, and the traditional flow is subjected to a process of data transmission and physical sending for many times in the middle, wherein one link is deviated, and mismatch or mismatching between the dental mouthpiece and a patient is easily caused. Meanwhile, the packaging cost, the logistics cost and the time cost in the physical sending are all higher. This mode of delivery does not allow for immediate delivery after medical treatment and the patient experience is poor. Meanwhile, a plurality of uncertain influencing factors exist in the patient condition during a longer waiting period after the treatment, such as tooth arrangement changes again, tooth health conditions change, correction deviation occurs in the wearing process, dental sockets are damaged in the wearing process, and the like, so that the dental sockets need to be timely adjusted and even manufactured again, which is a technical problem which is difficult to solve in the current production mode.

In conclusion, the manual/semi-automatic production has large occupied space and high cost; the traditional delivery mode has long period and high cost, and can not meet the needs of doctors and patients. Therefore, the design of the one-stop type dental floss production system has important significance for realizing the whole dental floss production flow in a small space, and manufacturing beside a chair and delivering instantly.
