Description

Technical Field

[0001] The present invention relates to the technical field of medical devices and their peripheral supporting facilities, and in particular to an oral multifunctional vacuum therapeutic device and a use method thereof. Background Art

[0002] Pulp disease and periapical disease are one of the most common and major infectious diseases in the oral cavity. Root canal therapy (RCT) is the first choice and the most effective treatment for pulp disease and periapical disease.

[0003] Clinically, the steps of root canal treatment include root canal preparation, irrigation, disinfection and filling. Root canal preparation is the key step of root canal treatment, including mechanical preparation and chemical preparation of the root canal. Successful root canal treatment should completely remove the infected substances in the root canal, eliminate the infection, and fill it tightly. The smear layer produced during mechanical preparation will provide a matrix for bacterial colonization and growth, and may affect the tightness of the root canal filling, leading to microleakage. Calcium hydroxide is the most commonly used root canal disinfectant, which has antimicrobial potential, organic tissue dissolving ability and anti-inflammatory effects. However, calcium hydroxide must be completely removed before root canal filling as a root canal sealant. Calcium hydroxide remaining in the root canal will hinder the sealant from penetrating into the dentinal tubules, affect the bonding strength of the dentin, and increase the risk of apical leakage. In addition, calcium hydroxide residues can react chemically with some sealants and change their physical properties, reducing the flow and solidification time. Therefore, before root canal filling, it is a very critical step to thoroughly remove the smear layer and disinfectant calcium hydroxide in the root canal. However, due to the complexity of the anatomical morphology of the root canal system and the limitations of the penetration of the irrigation solution during positive pressure irrigation with a traditional syringe, it is usually difficult to completely clean the root canal system, especially the apical 1 / 3 area. Teeth with large areas of tooth tissue defects cannot provide the retention force required for full crown restoration, and often require post-core crown restoration to provide support and retention. In recent years, fiber posts have gradually become a preferred root canal post material in clinical practice due to their advantages such as similar elastic modulus to dentin, good biocompatibility, corrosion resistance, and stable performance. However, fiber post restoration still has a certain failure rate. A large number of studies have found that fiber post bonding failures often occur at the dentin / resin bonding interface of the post channel wall, further proving that the smear layer on the surface of the dentin wall of the post channel has an adverse effect on the bonding effect of the fiber post. Since instruments are used to cut the root canal dentin and root filling materials during post channel preparation, the debris generated in the process adheres to the dentin surface to form a smear layer. At this time, the composition of the smear layer is different from the debris generated by root canal preparation, including gutta-percha tips, root filling paste, etc. The presence of an excessively thick smear layer will block the opening of the dentinal tubules, hinder the penetration of the bonding material into the dentin, and thus affect the bonding effect of the fiber post. Therefore, the first prerequisite for improving the success rate of fiber post bonding is to try to remove the smear layer and residual root filling paste in the post channel.

[0004] Jawbone cystic lesions are diseases that present as cystic changes clinically and radiographically, such as jawbone tumors and jawbone cysts, which affect the oral and maxillofacial regions. Surgery is the first-line treatment for maxillary cystic lesions. Currently, the surgical methods for treating cysts mainly include curettage, decompression by fenestration, extensive resection of cystic lesions, etc. For large-sized jawbone cystic lesions that affect adjacent tissue structures such as teeth, the inferior alveolar nerve, and the maxillary sinus, decompression can be performed to reduce the cyst cavity, promote osteogenesis, and effectively protect adjacent tissues. In recent years, the potential application of mechanical stimulation in bone regeneration has been attracting increasing attention from researchers. Studies in multiple fields have shown that negative pressure can promote bone regeneration by promoting osteoblast differentiation.

[0005] Due to the complexity of the tooth root canal system and the existence of irregular canal morphologies such as oval canals, canal isthmuses, and lateral canals, it is very difficult to clean the root canal system. Research has shown that root canal preparation instruments can only clean 40% of the root canal wall at the apical part of the oval canal. Therefore, it is difficult to achieve the goal of thoroughly cleaning the root canal system by relying solely on mechanical preparation and traditional irrigation methods. In fiber post restoration, due to mechanical cutting during post space preparation, a smear layer is formed on the surface of the post space dentin wall. The composition of this smear layer is different from the smear layer generated during root canal treatment. It contains not only inorganic debris and collagen fiber debris, but also residual infective substances, gutta-percha, and root canal sealer, etc., and is even more difficult to remove. The presence of the smear layer will block the dentinal tubules in the post space, prevent resin tags from penetrating into the dentin, reduce the retention force of the micro-mechanical interlock at the bonding interface, and affect the bonding strength of the fiber post. At the same time, the use of root canal irrigation solutions is also a "double-edged sword". Research has confirmed that the combined and alternating irrigation with a 5.25% mass percentage concentration of NaClO (sodium hypochlorite) solution and a 17% mass percentage concentration of EDTA (ethylenediaminetetraacetic acid) solution has a significantly better cleaning effect on the smear layer on the root canal wall and the post space dentin surface than other irrigation solutions. However, when NaClO and EDTA appear in the post space at the same time, the available chlorine level in NaClO will decrease significantly, and at the same time, a certain tissue dissolving ability will be lost, affecting the cleaning ability. Secondly, any irrigation solution may cause liquid residue after irrigating the post space. If sufficient drying is not carried out, these residual irrigation solutions will affect the bonding strength between the post space dentin and the resin. However, the existing root canal irrigation systems on the market, such as the Gentlewave system, have a single function and only have an efficient irrigation function for root canal treatment, and have not applied the principle of vacuum negative pressure to other oral fields. Secondly, the cost of this system is high, with a single unit purchase price of more than 1 million yuan, and the cost-benefit ratio is low, so the enthusiasm of domestic and foreign medical institutions to introduce it is not high.

[0006] In addition, for large jaw cystic lesions that affect adjacent tissue structures such as teeth, inferior alveolar nerve, maxillary sinus, etc., traditional treatment methods mainly include curettage, fenestration decompression, extensive resection of cystic lesions, etc. However, traditional fenestration decompression has problems such as an increased risk of infection, unstable recovery time and prognosis.
