Prior to answering the question, What is a zirconia abutment, I will briefly explain what a dental implant abutment is. A dental implant is usually a titanium screw that is placed into either the upper or lower jaw. A dental implant is more like a tooth root than a tooth. What most people consider a tooth is the whitish thing that we see in the mouth. The dental implant must have something for the tooth to attach to : therefore the tooth is actually a crown, the crown covers the abutment and the abutment attaches to the dental implant. Traditionally the dental implant abutment is made from the same material (titanium) as the dental implant. Titanium is metal in color. We have all seen smiles that show that dark line near the gum line. The dark line is usually the metal in a porcelain fused to metal crown. With the tremendous advancements in cosmetic dental materials, a metal substructure is no longer needed. But if the dental implant abutment is metal colored, that will show. In this picture, two white zirconia dental implant abutments are visible.
