Dental Resin and Nanotechnology: Benefits and Disadvantages
The emergence of nanotechnology in dentistry has made composite resin filling materials a viable alternative for filling cavities. Silver is less toxic to human cells, and Zeolite enhances adhesion. It is also essential to consider the clinical context and the potential risks of nanotechnology 강남치과 when evaluating dental applications. However, these materials have inherent physical and chemical limitations that limit their applicability for tooth-colored restorations. In this article, we discuss some of the disadvantages of using composite resins. To better understand the benefits and drawbacks of these materials, we will look at the pros and cons of each.
Nanotechnology improves esthetics
The application of nanotechnology in the production of composite materials for dental use has been widely studied, with various applications being proposed for improved durability and esthetics. However, there are many issues associated with their use, including safety, efficacy, and practicality. Different nanomaterials possess varying levels of effectiveness and mechanical properties. While some offer superior aesthetic and polishing properties, others can cause wear or have undesirable side effects.
A number of applications for nanomaterials are emerging in dentistry. The use of nanocoatings on dental implants is one example, with the potential to improve osseointegration. Nanorobots are also being developed to print new enamel. But despite the recent advances in nanotechnology, it is not just the cosmetic benefits of the materials, but also the clinical and cosmetic value of dental implants.
Silver is less toxic to human cells
A study in mice revealed that dental silver was less toxic to human cells than standard amalgam. This is due to the silver’s ability to activate mast cells, which are critical for immune system function and play a role in allergic reactions and wound healing. In addition, silver activates mast cells by bypassing early signalling events, causing them to attack microbial cells before they have a chance to colonize. Moreover, silver also stimulates the lymphatic system, which filters toxins from the blood.
Research has revealed that silver is a more efficient disinfectant than most other metals. Silver is known to have a bactericidal effect on many different bacteria, including P. aeruginosa. It is also less toxic to human cells when it is incorporated into dental resins. The antimicrobial effect of silver is particularly beneficial because it can kill both Gram-positive and -negative bacteria.
Zeolite enhances dental adhesion
In recent years, zeolite fillers have been studied for their potential to increase the adhesion of dental materials. While this substance is commonly used for its antimicrobial properties, there are few studies evaluating its efficacy in a variety of dental applications. To address this problem, we conducted a systematic review of the literature on zeolite in dental materials, focusing on its antimicrobial properties and mechanical properties. We used PubMed and Ovid Medline databases, as well as reference materials to identify relevant studies. We also conducted nitrogen adsorption/desorption tests to evaluate the effectiveness of each modification process.
The composition of zeolites A and X was determined through ion exchange. Then, they were impregnated with methacrylic acid, which was used as a bonding agent. Incubation in saline confirmed that these zeolites were able to release calcium ions comparable to their calcium phosphates-filled counterparts. The antimicrobial activity of these composites was further increased after incorporating zeolites into the resin.
Composite resins have inherent physical and chemical property drawbacks
The mechanical properties of dental composites are determined primarily by the filler component. Compared to the polymer resin matrix, the reinforcing fillers have significantly higher mechanical properties. As a result, these materials tend to follow the predictive models based on the mechanics of complex viscoelastic structures and not a simple “rule of mixtures.” In addition to this, there are also some factors that affect the wear of the composites.
The physical and chemical properties of composite resins are highly dependent on the type of reinforcing filler particles, polymer network-forming monomers, and coupling agent used. Some research has investigated the effects of reinforcing particle size and interfacial modifications on these properties. The drawback of dental composites is that they lack strength against intra-oral fracture. However, significant developments in dental resin have been made by developing new polymers with improved shrinkage and degradation resistance.
