Description

A gutta-percha tip integrated with silver-containing titanium alloy for root canal retention and apex sealing

technical field

The invention relates to the field of stomatology, in particular to a silver-containing titanium alloy root canal internal retention and apex sealing integrated gutta-percha tip used in root canal treatment.

Background technique

Root canal therapy is the most commonly used effective treatment method for pulp disease and periapical disease in the world. The principle of root canal therapy is to remove most of the infection in the root canal by mechanical and chemical methods, and to fill the root canal, seal The crown prevents the occurrence of periapical lesions or promotes the healing of periapical lesions that have occurred;

In the existing technology, such as the authorized invention patent, application number: 201621237319.7, application date: 2016-11-18, patent name "root canal filling tip", the structure of this technical solution is most similar to this technical solution, but the comparison document There is a lot of room for technical improvement in the technical solution;

The reasons are as follows: in the comparison document, “the root canal filling tip includes the sealing section, the filling section and the tail section”, in which the sealing section and the tail section are both vanadium-free and nickel-free titanium alloy wires, the sealing section is made of metal material, and the sealing section is located in the tooth. For the root canal tip, on the one hand, due to the small internal size of the root canal, the size of the closed section is even smaller, which greatly increases the difficulty of processing the closed section, and the processing cost is very high. Even if it can be produced, it is far beyond the reach of the consumer group. On the other hand, due to the high metal strength and poor flexibility, it puts forward very high requirements for the dentist to perform the medullary cavity expansion, which greatly increases the operation time and difficulty coefficient, and the requirements for the dentist are extremely high. High, poor versatility. The more important issue is that the key to root canal treatment is the sealing of the apical area. The sealing section is made of metal material, and the sealing section and the inner wall of the root canal apex are both hard tissues. The two are in rigid contact, and the matching degree is poor. The sealing effect is poor, which seriously affects the sealing of the apical area and leads to the failure of root canal treatment. Another way in the prior art is to use gutta-percha tips completely. This technical solution is the most commonly used. On the one hand, it is because The cost is low, on the other hand, because of the good airtightness, but the problem of the gutta-percha tip is that it has low strength and no retention effect on the tooth filling material. The resin filling material on the patient's teeth is easy to fall off, which affects the long-term efficacy;

In summary, there are many practical problems in the existing technical solutions, and they cannot be fully applied to root canal therapy, and many problems remain to be solved.
