Problems solved by technology

However, compared with traditional glass ionomer cement or resin-modified glass ionomer cement materials, the fluoride ion release of these materials is often short-term or in a small amount, and the fluoride ion release often occurs one day after the restoration material is used. or several days, fluoride ion release is unsustainable

Embodiment 1

[0034] Embodiment 1: The preparation method of the one-component light-cured dental restoration composite resin of formula 1

[0035] The final calculated one-component light-curing polymerized composite resin of formula 1 is as shown in the above table 1, and the actual preparation process of the composition of formula 1 is demonstrated in the following steps:

[0036] (1) Weigh 9.43 grams of HEMA-Phosphate, 3.44 grams of HEMA, and 12.3 grams of distilled water, place them together in a 100-ml capacity PP plastic beaker and mix to form an acidic aqueous solution, and use pH test paper to test the acidity of the solution , between pH=0-1;

[0037] (2) 24.83 grams of barium-calcium-F-Al-Si glass ionomer cement fillers whose average particle size is 4.5 microns are added in the acidic aqueous solution prepared in step (1), and are adjusted with dental polytetrafluoroethylene plastics Rapid blending: The mixture reacts quickly to thicken and form lumps, but the resulting lumps h...

Embodiment 2

[0042] Embodiment 2: The preparation method of the one-component light-curing dental restoration composite resin of formula 2

[0043] The final calculated one-component light-curing polymerized composite resin of formula 2 is as shown in the aforementioned table 1, but the actual preparation process of the composition of formula 2 is demonstrated in the following steps:

[0044] (1) Prepare a resin liquid according to the following material mixing ratio: 29.88 grams of 4-META, 39.17 grams of UDMA, 15 grams of HEMA, 14.83 grams of TEGDMA, 0.2 grams of CQ, 0.40 grams of EDMAB; test with pH test paper, the pH value is about 2.

[0045] (2) Take 80 grams of the resin liquid prepared in step (1), add 20 grams of distilled water, and make it mix to form a suspension mixture. Glass ionomer cement filler G018090 111 grams was then mixed in to form a thicker paste with a milky white color indicating excess water in the mixture.

[0046] (3) On the second day, the consistency of the w...

Embodiment 3

[0048] Embodiment 3: The preparation method of the one-component light-cured dental restoration composite resin of formula 3

[0049] The final calculated one-component photocurable polymerized composite resin of formula 3 is shown in the aforementioned Table 1, but the actual preparation process of the composition of formula 3 is demonstrated in the following steps.

[0050] (1) Similar to the step (1) of the above-mentioned Example 2, prepare a resin liquid with the following composition: 4-META 29.88 grams, UDMA 20 grams, BisGMA 19.17 grams, HEMA 15 grams, TEGDMA 14.23 grams, CQ 0.2 grams , EDMAB 0.40 grams; with pH test paper detection, the pH value is about 2.

[0051] (2) Take 1 gram of 4-META resin, add 2.2 grams of distilled water in a molar ratio of 1:36, and add absolute ethanol to a capacity of 50 ml to dissolve 4-META in the solution and convert it into an acid form (4- MET). Then add 25 grams of G18090 glass ionomer cement filler and continue to stir for 15 minu...

Abstract

The invention discloses a single-component photocuring composite with the fluoride ion release property for dental restoration and application of the composite. The raw materials used for preparing the single-component photocuring composite with the fluoride ion release property for dental restoration comprise water soluble or at least partially water soluble acid molecule structure-containing polymeric resin monomers or oligomer or a mixture thereof, glass ionomer cement filler with the fluoride ion release property and a photocuring polymerization initiating system. The photocuring composite is the single-component photocuring composite, use is convenient, the fluoride ion release property is achieved, and meanwhile the mechanical and physical properties are achieved; the composite can be used as gasket materials under dental adhesives and other dental restoration materials, pit and fissure sealing materials on surfaces of teeth, tooth filling repair / restoration materials, post-core composition materials for dental crown restoration, root canal orifice sealing materials and photocuring orthodontic cement bonding materials and used for other dental treatment and restoration application.

Description

technical field [0001] The invention belongs to the technical field of materials for tooth restoration in the department of stomatology, and in particular relates to a single-component light-curing composite material with fluoride ion release characteristics for tooth restoration and an application thereof. Background technique [0002] Restorative materials are one of the key research contents in the field of dentistry. Although the chemical, mechanical, physical, and biological properties of the currently used restorative materials have been significantly improved, the research and development of materials for preventing secondary caries has always been one of the key projects of the academic community and related companies. The release of fluoride ions in materials has always been recognized as an effective means to prevent secondary caries, so related restoration materials containing fluoride ions have also emerged as the times require. For example, the traditional glas...
