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.
Old defective restorations on teeth 35 and 36.
Preoperative occlusion check to locate the occlusion points on the teeth.
Rubber dam isolation to get a clean field for adhesive procedures.
The old restorations were removed.
The cavities were sandblasted after finishing preparation.
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.
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.
The natural anatomy of the tooth was reestablished.
Occlusion checked, little adjustment was needed.
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.
