What two items are needed to create a proper contour of a new restoration?

Creating a proper contour for a new dental restoration is crucial for ensuring optimal functionality and aesthetics. The matrix band and wedges are essential tools for this process.

A matrix band is used to provide a mold for the restoration material, mimicking the shape and contour of the natural tooth structure. It allows for the accurate placement of materials, ensuring that the restoration has the proper dimensions and fits seamlessly within the tooth structure. The use of a band helps in maintaining the margins of the restoration and prevents material from spilling over into the adjacent teeth or areas.

Wedges are employed alongside the matrix band to ensure that the band fits tightly against the teeth. This prevents gaps and helps achieve close adaptation at the tooth-restoration interface, promoting better retention of the filling material. Wedges also help to create the necessary space for the material to flow and form a proper contour, critical for both function and aesthetics.

Together, these items facilitate the creation of a well-contoured and properly formed restoration that mimics the natural anatomy of the tooth, ultimately contributing to better dental health outcomes.
