Methacrylate Based Cements
Methacrylate based cements are an important class of dental materials used in various dental procedures. For example, they are used to construct crowns, bridges and dentures, as well as for making impressions for braces and retainers. In addition, they can also be used for other applications such as bonding braces or dental imitation materials.
Methacrylate based cements are often referred to as ‘composites’ because they are combinations of both hard and soft materials. This is due to their ability to form a durable bond with both hard and soft substances. The composite material can usually be formed into any desired shape and then injected or poured into the required area.
In order to be effective, methacrylate based cements must be properly mixed and poured into the area where the dentifrice is required. Depending on the specific product being used, the mixing process involves either manual stirring or using a machine (usually a forced air mixer).
After the methacrylate based material has been mixed, it can then be injected or poured into the area which requires filling. This process is known as ‘coring’. It is important that during this process the material used is allowed to cool and settle, as this will ensure the material properly adheres to the underlying surface.
Methacrylate based cements can be used in a variety of ways. For example, they can be used to fill teeth, repair cavity filling, bond braces or to seal dentures. The product is also commonly used in crown and bridge procedures as it is formable, exhibits great strength and forms an excellent bond with composite restorative materials.
The primary disadvantage of methacrylate based cements is their cost. As they are more complex and involve more labour intensive procedures they are generally more expensive than traditional cements. In addition to this, they require regular maintenance to keep them in good condition as they are more sensitive to changes in temperature and humidity than traditional cements.
Despite this, many dentists prefer methacrylate based cements due to their versatile range of uses and excellent strength and durability. Due to these pros and cons, it is important for a dentist to weigh up the potential costs versus the potential benefits of any given procedure.
In conclusion, methacrylate based cements are an important class of dental materials whose versatile range of uses and excellent strength and durability make them a popular choice for many dentists. However, due to the cost and maintenance involved, dentists must decide if the potential benefits of the procedure are worth the extra cost.
