Abstract
The invention discloses a production method of a personalized obturator. The production method includes: step 1 performing spiral captive test (CT) scanning for the maxillofacial region of a patient to obtain a scanning data file; step 2 placing the scanning data file into three-dimensional modeling software to perform three-dimensional modeling so as to obtain three-dimensional model data of soft and hard tissues of the patient; step 3 molding the three-dimensional model data through a numerical control fast molding device to obtain a solid model; step 4 placing the trimmed personalized solid model in a coloboma cavity of the patient and using an impression material to take molds for the solid model on the in-position palate portion in the coloboma cavity of the patient and in the upper mandible dentition or the upper mandible occlusion area to obtain an obturator model comprising the intra-oral coloboma cavity form and dentition; and step 5 completing production of the personalized obturator on the obtained obturator model. The technical scheme of the production method has the advantages of reducing production time of the obturator, reducing production difficulty of the obturator and enabling the obturator to be well matched with the practical conditions of the patient.

For palatine defect of maxilla patient, need to carry out the traffic that upper jaw prosthesis repairs to stop the mouth and nose chamber, improve patient's dysmasesis of pronouncing.For the patient of defect of maxilla, the making maintenance is good, and closure is good, and the rational obturator of occluding relation is most important.The making complicated operation of conventional congestion device, length consuming time, strong to maxillofacial prosthesis doctor's technology and experience dependency, also be subject to the restriction of patient's self-condition.
Summary of the invention
Make existing the problems referred to above for obturator in the existing palatine defect of maxilla patient treatment, now provide a kind of and be intended to shorten Production Time, reduce the manufacture method of the personalized obturator of manufacture difficulty.
Concrete technical scheme is as follows:
A kind of manufacture method of personalized obturator wherein, comprises the steps:
Step s1, patient's jaw face is carried out Spiral CT scan, obtain scan data file;
Step s2, described scan data file is imported 3 d modeling software, carry out three-dimensional modeling, to obtain the three-dimensional modeling data of patient's soft or hard tissue;
Step s3, with described three-dimensional modeling data by the molding of numerical control rapid molding device, to obtain the Extraordinary physical model;
Step s4, will through the finishing described physical model in place in the damaged chamber of patient, and the palatine after in place in the damaged chamber of patient to described physical model with impression material and maxillary dentition or upper jaw anodontia close the zone and carry out delivery, to obtain to comprise the obturator model of intraoral defect chamber form and denture;
Step s5, on described obturator model, finish the making of personalized obturator.
Preferably, it is as follows to carry out the concrete steps of three-dimensional modeling among the described step s2:
Step a1, according to the position of osseous tissue and utilize recessed maintenance, form and the height of design hollow or solid personalized obturator;
Step a2, reserve air flue in the threedimensional model of described personalized obturator top for upper respiratory tract;
Step a3, add the needed attaching structure of delivery in the threedimensional model palatine of described personalized obturator.
