Description

Novel special filler for preparing pile nuclear impression

Technical Field

The utility model relates to the technical field of medical equipment, specifically a novel special obturator is prepared to stake nuclear die.

Background

The post-nuclear crown repair is a common repair method for repairing large-area tooth defects, and the acquisition of a complete post-nuclear impression is an important step in the process of repairing the post-nuclear crown. The integrity of the core impression of the post directly influences the suitability of the post and the design of the height and the direction of the core, is very important to the long-term curative effect of the restoration on the post, and determines the success or failure of the restoration treatment.

The most accurate material for taking the impression for repairing the post-nuclear crown in the department of stomatology is silicon rubber, the silicon rubber materials are mixed according to the proportion of 1: 1, and the mixture is stirred and mixed to generate chemical reaction, and then the mixture is solidified and shaped. When in operation, the silicon rubber is firstly drilled at the root canal orifice of the tooth, then the silicon rubber is poured into the root canal by the spiral delivery needle, a core-making die is copied after the silicon rubber in the root canal is solidified, a technician is handed to make a core, and the core is stuck to the root of the tooth of a patient by a doctor after being made.

Gaps and air bubbles are easy to generate in the process of taking the pile impression clinically, and the pile core impression has the defects of high proportion and high requirements on the operating technique of doctors. The clinical self-made impression material is filled to 9 syringe needles, the syringe needle of 8cm length when buying 9 syringe needles, and later stage nurse oneself grinds length about 2cm with dental turbine, cuts off the back and on the head polish polishing, the doctor of being convenient for is bent according to root canal length. The process of bending the needle head has potential safety hazard and is not beneficial to the operation of medical staff; the original clinical use of a 5ml needle tube proves that the injection is laborious and the doctors can not carry out accurate root canal filling, so that the novel special filling device for preparing the pile-core impression is provided.
