Technical Field
The application relates to the technical field of medical equipment, in particular to a handheld self-breaking dental fiber pile.
Background
The fiber post is a novel non-metal composite dental restoration material, and is often used together with a resin core and a crown restoration body to restore large-area tooth defects; in recent years, the metal corrosion resistance, good biocompatibility, excellent aesthetic property, moderate elastic modulus, simple operation and other advantages are popular among dentists and patients, and are widely popularized and applied; the material is clinically regarded as the first choice for repairing large-area tooth defects of anterior teeth by dentistry.
The fiber piles act in a completely different mode from root tube piles made of other materials, besides obvious aesthetic advantages, the fiber piles can not be corroded like non-noble metal piles (including stainless steel piles), because the hardness degree (elastic modulus) of the fiber piles is very close to the tooth structure, the fiber piles can act together with teeth instead of acting relative to the teeth, and the characteristic is favorable for preventing the generation of tooth fracture and other problems; all the components used for producing the fiber pile have high biocompatibility, while the stainless steel pile can cause nickel and chromium to be ingested by human bodies, other non-noble metal casting alloys also contain certain uncertain elements, and the fiber pile is a pure industrial composition and comprises the following components: (1) specially oriented equilibrium drawn reinforcing fibers; (2) specially preparing an epoxy resin filling material; (3) integrating an interface: a bonding system between the filler material and the fibers; the reinforcing fibers occupy more than 80% of the volume of the pile (more than 60% by weight) and are subjected to a pre-stretching process during production to stably achieve the desired mechanical properties, the fibers within the pile being pre-stretched along a central axis in a uniform and uniform manner, the transverse force exerted on a particular material, assuming an angle of 45 °, will be simultaneously subjected to two different forces: one side will be subjected to compressive forces and the other side will be subjected to tensile forces, while the middle part will be subjected to shear forces, so it is crucial to achieve high performance and high strength in compression, tension and shear.
Because of their importance, dental fiber posts need to meet the following functional requirements:
1. the traditional pile body with the elasticity modulus similar to that of dentin has higher elasticity modulus, is easy to generate larger stress concentration on a tooth body, and when the traditional pile body is subjected to poor stress, the tooth body tissue is split or root-folded to cause the repair failure; the fiber pile simulates the mechanical property of dentin, and the stress is transmitted into the whole dentin structure, so that the root fracture risk is reduced;
2. outstanding bending strength and tensile strength, which are basic requirements for pile materials, namely the super-strong mechanical properties of fiber piles, and stronger bending strength and tensile strength than those of metal piles;
3. the bonding property of the excellent bonding property fiber pile and the resin bonding agent far exceeds that of a metal pile, the surface of the fiber pile is porous under an electron microscope, the maximum bonding area can be provided, and meanwhile, the bonding agent enters the micropores to form lock catches, so that the chemical bonding property is enhanced;
4. the color is similar to that of teeth, the excellent aesthetic effect is that the restoration has no any shadow and is exactly similar to real teeth;
5. good fiber piles with repeatable repairability can be easily removed by a drill, and can be removed within a few minutes if metal piles fail, and tooth roots are likely to need to be pulled out;
6. the operation is simple, the operation technology of the fiber pile for reducing the times of treatment is simple and easy to use, the operation time is short, the treatment can be completed by one time, much time is saved, the pain of a patient is relieved, and the inconvenience caused by multiple times of treatment is eliminated;
7. metal corrosion metal piles are easy to corrode, byproducts can enter the interface between the pile and a tooth root, grey and black dyeing is generated on the edge of a crown and a gum, and the fiber pile repair is not influenced.
8. Various biological performance tests and clinical applications carried out by the good biocompatible fiber pile show higher safety;
9. the metal in the nuclear magnetic resonance oral cavity is not influenced, so that the nuclear magnetic resonance image is influenced to a certain extent, and the fiber pile repair is not influenced.
The steps of the fiber pile in use are as follows:
the method comprises the following steps: root canal preparation
Separating the affected teeth with rubber dam;
removing the gutta-percha filling by using a pre-drill;
selecting an appropriate drill to prepare the root canal, typically from about 1/2 to 2/3 deep into the root canal
Step two: trial fiber pile
The tweezers are used for clamping the fiber pile, so that the bonding surface is prevented from being polluted and the bonding strength is prevented from being influenced
Step three: trimming the length of a fiber post
Taking out the fiber pile, cutting the fiber pile according to the required length
Cutting the fibre pile with cutting sand or needles, without using pliers, scissors or tweezers, so as not to damage the pile structure
Step four: acid-etched root canal
Acid etching the tooth surface to be bonded, washing off the adhesive, sucking the excessive water in the root canal with large-size paper tip, and maintaining certain surface humidity
Step five: coating adhesive
Uniformly coating resin adhesive on the bonding surface of the root canal and the tooth and the surface of the fiber pile twice, sucking off the excessive adhesive with a paper tip, drying, and illuminating the bonding surface of the root canal and the tooth for 10-20 seconds
Step six: bonding of
The prepared intraoral injection head for the resin cement is delivered into the root canal, and the intraoral injection head gradually retreats from the apical part to the root canal orifice to deliver the resin cement into the root canal
And (3) coating the surface of the fiber pile with the well-adjusted resin cement gate, placing the fiber pile in a root tube in place, keeping the pressure for 10 seconds, and aligning a light curing lamp to the top of the fiber pile for illumination for 40 seconds to ensure that the resin cement gate is cured.
Step seven: repair of the coronal nucleuses
(1) Blending the component A of the Hard Core dual-curing corona-Core resin cement with the component B at a ratio of 1:1, adjusting and stirring for 20 seconds, and covering and sealing the mixture in time after use;
(2) injecting the crown core resin into a proper crown core forming cap, and paying attention to the elimination of bubbles;
(3) filling the adjusted material into the nuclear forming cover, and buckling the nuclear forming cover on the pile to ensure that the material is tightly adhered to the shoulder; primarily curing by illumination for 20 seconds, removing redundant resin, and continuing illumination until curing, wherein if illumination is not used, the chemical curing time is about 8 minutes from the beginning of blending; or directly stacking the core with the core material to repair the core;
(4) shining the crown core resin material through different sides by using a light curing lamp;
(5) after the nuclear material is completely solidified, removing the nuclear forming cover and finishing the shape of the crown nucleus;
according to the steps, in the prior art, the fiber pile needs to be cut by cutting sand or a machine needle for cutting the fiber pile; can not use pliers, scissors or tweezers because pliers, scissors or tweezers can destroy the structure of fibre stake, and it is comparatively loaded down with trivial details through cutting sand piece or car needle intercepting fibre stake step, reduce work efficiency, and if cutting sand piece or car needle operation is improper can also break the structure of meeting fibre stake, use very inconvenient.
Therefore, a new technical solution is needed to solve the above technical problems.
