Description
Technical Field
The invention relates to the field of denture preparation, in particular to a complete denture integrated preparation method based on DLP (digital light processing) photocuring 3D printing.
Background
The traditional denture repair is performed only in the stage that the wound of tooth extraction is healed and the alveolar ridge absorption tends to be stable, usually, a patient needs to wait for about 3 months after tooth extraction, and long-time dentition loss has great influence on the psychological state, the face appearance, the chewing and swallowing functions, the pronunciation and the like of the patient. The patient urgently wants to recover the dentition as soon as possible and shorten the edentulous time as much as possible. Therefore, the immediate complete denture or half denture needs to be worn by the patient as soon as possible after tooth extraction so as to meet the requirements of the patient, avoid the tooth extraction period of the patient, recover the physiological functional stimulation of the tooth lacking area of the patient in time, meet the aesthetic and psychological requirements of the patient, reduce various damages to the patient caused by dentition deficiency, increase the confidence of the patient, and fulfill the aims of compressing the tooth extraction wound and reducing bleeding.
The immediate complete or half denture is prepared into a memory model before tooth extraction, and the normal jaw position and the jaw distance are recorded as references for determining jaw position relation and tooth arrangement later. Functional impressions of the remaining teeth and the edentulous areas are usually taken with individual trays, and artificial stone models are poured to record jaw relations from the natural teeth still present in the mouth. Putting on a shelf, trying on the back teeth, completing the complete or half denture, and immersing in the disinfectant for later use. After the residual teeth are pulled out and the alveolar bone is trimmed, the immediate artificial tooth is worn immediately and is prepared and ground.
The traditional instant complete denture or half denture is mostly made of polymethyl methacrylate by adopting a thermosetting filling process, the manufacturing process needs the steps of boxing, filling, pressurizing, water bath polymerization and the like, and the manufacturing process is complicated and wastes time and labor. In addition, in the manufacturing process of the traditional thermosetting filling process of the complete denture or the half denture, the defects that the gypsum model has cracks, or the denture base after being manufactured has deformation or has air bubbles and the like are caused by the influences of factors such as the deformation of the base wax pattern, the difficult accurate control of the proportion of the polymethyl methacrylate powder liquid, the uneven pressurization of the mould box placed on a squeezer, the difficult accurate control and control of the temperature rising speed and the holding time in the heat treatment process and the like. Furthermore, the thermosetting base resin shrinks to some extent after polymerization, and if the shrinkage is too large, the fitting between the denture base structure surface and the oral cavity mucosa surface is poor, and the retention is affected. In addition, the tooth arrangement of the conventional complete denture or half denture is finished by a technician, which takes long time, and the quality of the tooth arrangement is closely related to the technical level of the technician, so that quality deviation is easy to occur. And the immediate denture is different from the conventional denture repair and needs to be pulled out of a plurality of teeth at one time, so that the model trimming before tooth pulling is difficult to be accurate, the stability and the retention of the prosthesis are directly influenced, the number of times of patients seeing a doctor is large, and the repair is related to a plurality of times.
In addition, because the alveolar bone is unstable and can be absorbed continuously within 3 months after tooth extraction, the complete denture or the half denture is easy to have the symptoms of looseness, non-fit, poor retention and the like after being worn for a period of time immediately, a temporary complete denture or half denture needs to be manufactured again, and the manufacture needs to take a quite long time again, so that inconvenience is brought to a patient.
In order to shorten the manufacturing period, reduce the manufacturing cost and improve the quality, false teeth are manufactured by adopting a 3D printer on the market; because 3D printer prints the advantage that the denture has the cycle to be short, with low costs and quality relatively good to the application of 3D printer in the dental trade has been accelerated.
However, in the process of manufacturing the complete denture by the 3D printer, the base and the denture are printed by the 3D printer separately, and then the base and the denture are adhered together to complete the manufacture of the complete denture; just as the printed base and the false tooth need to be cemented together, the integrated preparation of the base and the false tooth cannot be realized; meanwhile, the base and the denture are required to be cemented together, so the bonding strength of the base and the denture and the quality after bonding are poor, and the manufacturing process is relatively complex; moreover, in the process of printing the base and the denture, the peeling force of the printing platform from the trough is large, and the density consistency of the base and the denture at each position is poor due to the uneven concentration of the solution in the trough, so that the strength of the complete denture is affected.
Therefore, there is a need for a complete denture integrated preparation method based on DLP (digital light processing) photocuring 3D printing, which can realize complete denture integrated preparation, has small peeling force and good consistency of density of the base and the denture, and overcomes the above defects.
