Description

Comfortable type tooth of anticreep mould is with tray

Technical Field

The utility model relates to a dental medical appliance, in particular to a comfortable dental tray for preventing the falling off of a mold.

Background

At present, taking an impression in the process of oral cavity restoration and orthodontic treatment is an indispensable operation step, the operation is not complicated, but the demoulding phenomenon is frequently encountered in the operation process, and particularly, the demoulding is very easy in the process of taking the impression for an orthodontic patient with a bracket stuck in the mouth and a patient with irregular tooth arrangement in the mouth. The demolding refers to: when a doctor prepares an oral cavity model, firstly preparing an impression material, placing the impression material in a tray, then pressing the tray into the upper dentition or the lower dentition of a patient, at the moment, the redundant impression material flows out from the drainage holes of the tray, after the impression material is solidified, the tray has certain binding force with the impression material, the doctor takes the tray together with the impression material out of the patient, at the moment, the preparation of the oral cavity impression is finished, but in the process of taking the impression material out of the oral cavity, the impression material is partially separated from the tray even completely separated from the tray due to the reasons of incorrect demoulding technique of the doctor, too small drainage holes of the tray, unreasonable mixing and mixing of the impression material and the like, because strong negative pressure is formed among the impression material, oral cavity soft tissue and oral cavity saliva and resistance caused by the anatomical structure of the dental crowns in the oral cavity. If the impression is separated from the tray, the impression can be deformed, the plaster model poured by the doctor by using the deformed impression has larger difference with the real situation of teeth in the oral cavity, the prosthesis made by an oral technician on the oral cavity model with the larger difference, an orthodontic correction device and the like worn in the oral cavity of a patient can cause the wearing discomfort of the patient, various complications such as the non-close adhesion of the prosthesis and the teeth and the like can finally cause the failure of the prosthesis, the increase of the complications and the like. The fixed and movable restoration of dentition loss in the oral cavity, the manufacture of various orthodontic appliances and the like belong to high-precision restoration, an oral impression made by a doctor can accurately reflect the fine structure of oral tissue anatomy, and the inaccurate preparation of the impression and an oral model increases a lot of difficulties for later-stage denture manufacture, the trial wearing of a clinician on a restoration body and the like. Even if the model needs to be taken again, the model is made again, and the dental laboratory is sent again to make the restoration again, which undoubtedly increases the workload of doctors and technicians, prolongs the working time, and increases the time and psychological burden of the patient for seeing a doctor. Therefore, the tray which can prevent the demoulding phenomenon when a model is manufactured and ensure the accurate, stable and stable impression has important clinical significance. At present, similar products have not appeared.
