S4, performing film pressing manufacture on the hard model prepared in the S3 by using the thermoforming film;
s5, after the diaphragm formed by the whole dentition of S4 is taken down, the formed diaphragm of the affected area is sheared, and the range is expanded to the adjacent area so as to increase the stability of clinical operation;
S6, marking tooth positions on the formed film cut in the S5, and repairing the die;
S7, filling the photo-curing resin into the repairing mould in the S6 by a clinician, reversely buckling the prepared resin template at the affected teeth, photo-curing and forming, and recovering the attractive and occlusion relationship.
Preferably, the wax crown is manually carved by a technician using a wax dropping method when the templates of the upper and lower jaw models are made.
Preferably, the hard model in S3 is a model of whole gypsum.
Preferably, in S5, the shaped film piece of the affected area is cut, and the range is properly expanded to 1-2 adjacent teeth.
Preferably, in S4, the specific film pressing manufacturing process comprises the steps of firstly fixing a hard model and a hot forming film on a preheating frame, starting a preheating cabin of a film pressing machine to preheat the hot forming film, keeping the air pressure constant at 5bar at the moment, and pushing the whole preheating frame to enter the pressurizing cabin at the moment when the film is softened and pressing the pressurizing cabin to press the hot forming film on the hard model when the preheating time reaches 1-9S.
Compared with the prior art, the invention has the beneficial technical effects that:
The application can recover the shape of the affected dental crowns by using the model taken in the mouth, and manufacture the personalized mould which accords with the different tooth arrangement conditions of patients. The die can be used for remolding the appearance of the affected teeth by means of the die in clinical treatment, the attractive appearance and the occlusion relation are recovered, the external stimulation to dental pulp is reduced, the chewing function is improved, the dentin is protected, and the life quality is improved.
