Treatment guide plate for root canal treatment and preparation method thereof

Abstract

The invention discloses a treatment guide plate for root canal treatment. The treatment guide plate comprises a closing plate, and the closing plate comprises a matching surface matched with a tooth crown shape of a part of teeth or all teeth of an affected tooth or an affected tooth and an adjacent single tooth. Guide holes corresponding to corresponding root canals are formed in the closing plate, one end of each guide hole is located in the matching surface, the position design of the guide holes depends on the three-dimensional stress finite element analysis of the teeth, and a mechanical strut region of the teeth is avoided; when a drill pin penetrates through the corresponding guide hole to drill a marrow hole of the affected tooth, the mechanical strut structure of the affected tooth cannot be damaged by the drill pin, and the anti-stress structure of the tooth is protected; the teeth are prevented from being cracked when biting hard objects after operations. The invention further provides a preparation method. The preparation method of the treatment guide plate for root canal treatment is simple, mature and easy to popularize, and the prepared treatment guide plate effectively avoids damage to the mechanical strut structure of the affected tooth, so that the teeth can be prevented from being cracked when biting the hard objects after the operations.

Description

Technical field [0001] The invention relates to the technical field of oral auxiliary medical devices and their preparation, more specifically, it relates to a treatment guide for root canal treatment and a preparation method thereof. Background technique [0002] However, the tooth has a cusp structure, which causes the surface of the tooth to be round and uneven like a mountain, and the pulp cavity inside the tooth is hollow like an underground river in the mountain. Such a hollow structure needs a good mechanical support structure to withstand the bite force without breaking. [0003] Pulpitis is a very common disease in oral diseases. Its symptoms are mainly spontaneous pain. The reason is that the dental pulp is inflamed due to bacterial infection. Clinically, root canal therapy is used to treat pulpitis. Root canal treatment is to prepare and shape the root canal first, then disinfect and sterilize the root canal with drugs, and finally close the root canal to effectively co...

AI Technical Summary

Problems solved by technology

[0004] In order to find the root canal orifice, some operations in the prior art are: it is necessary to grind out part of the tooth tissue on the occlusal surface, exposing the pulp cavity and the root canal orifice, so that the operation can be performed under direct vision. The grinding of these healthy tooth tissues It is pointed out that the above-mentioned mechanical pillar structure may be destroyed, weakening the resistance structure of the tooth, and it is easy to cause the fracture of the postoperative tooth when biting a hard object, which happens from time to time in clinical practice.

[0005] Moreover, in the prior art, there is still a part of the operation that chooses to drill vertically at the tooth surface closest to the pulp cavity, just like oil drilling, and chooses the shortest path. When the food bears the pressure, such teeth are still easy to bite
