A simple way to replace the old defective restoration

Although it may seem a simple procedure, replacement of old defective restorations is often a path full of difficulties, from occlusion, contact points, and deep margins. For this reason using a composite with easy handling properties, a good choice in shade, and a good polishing system is important when dealing with such restorations.

The cavities were sandblasted after finishing preparation.

matices and wedge for restoration of adjacent proximal walls

After adhesive procedures, two matrices were placed simultaneously for mutual support. After modeling one proximal wall one matrix is removed to proceed to the other one, without removing the wedge. The contact point will be strong as there is only one matrix separating teeth.

layering raw composite in the posterior cavities

The proximal walls were built, class I cavity obtained, occlusal anatomy was created following the Essential Lines technique. The CompoSite (White Dental Beauty) material is very easy to handle.

finished composite restorations

The natural anatomy of the tooth was reestablished.

In our everyday procedures, we need to think well about the instruments and materials that we use. Good materials and good techniques ensure stable results, on a daily basis.
