Dental restorations with composite resin are the most common type of dental procedure. The dentist uses this type of restoration when the patient has a medium or large caries lesion. However, they can also be done after a tooth fracture.
Although this is a simple and standard procedure, the dentist requires a high-quality composite resin and enough practice and expertise to perform a successful restoration. However, the quality of the composite filling instruments also contributes to its success.
Furthermore, a good set of spatulas can make a huge difference when shaping the composite resin.
Composite Filling Instruments are any spatula or tool that helps the dentist mold and shape the dental composite.
They allow the dentist to recreate the tooth's natural anatomy using composite. Therefore, providing the dentist with the needs necessary to create a restoration that blends perfectly with the tooth.
Composite Filling Instruments usually consist of a pen-like tool with a special tip to shape the composite at both ends. Furthermore, each tip is shaped differently. This allows them to perform different functions.
However, this means that the dentist might need a complete set or a few composite spatulas with different tips. This way, the dentist can have the tools necessary to replicate every tiny detail of the tooth's natural anatomy.
Composite Filling Instruments are made of steel. Nonetheless, they are meant to be non-adherent. This property makes it easier to manipulate the composite resin as it doesn't stick to the spatula.
For this reason, some Composite Filling Instruments have a Teflon cover. This prevents the composite from sticking to it.
Lastly, since these instruments are meant to be used inside the patient's mouth, they are designed to be easy to clean. Moreover, they can be sterilized in an autoclave after being disinfected.
The function mechanism of Composite Filling Instruments are fairly straightforward.
After the tooth has been prepped, the dentist can use a spatula to grab a small portion of composite resin from the tube. This same spatula is then used to place the composite on the tooth.
Afterward, the dentist simply has to use the Composite Filling Instruments at his disposal to shape the composite in the desired way. This can be done by gently pressing it down with the spatulas and removing any excess composite.
Once satisfied with the results, the dentist can use the lamp light to light-cure the composite resin and harden it.
Nonetheless, the dentist can use the spatulas to add more resin composé on top of the light-cured restoration if a material increment is needed.
