Historically, Implant abutments were constantly made from metal and were either prefabricated or custom-made. Zirconia implant abutments provide an extremely aesthetic solution, especially for specific clinical conditions. Zirconia abutments are very versatile. Since they designed entirely using CAD/CAM technology or by scanning a wax-up before milling the abutment. Both options allow a zirconia abutment to be economically designed and created.
When to Choose a Zirconia Implant Abutment
One where the gingival tissue is thinner, it can expose the greyish hue of a titanium abutment implant in the cervical third of the implant restoration. This can detract from the most beautifully-made implant crown. A thin gingival tissue is unable to block the reflected light from metal abutments. Therefore selecting a zirconia abutment can overcome these limitations. One simple way to test whether a patient has thinner gingival tissue is to just insert a periodontal probe to the gingival sulcus. When it’s easy to see the probe through the tissue, then the patient has a thin periodontal biotype. Using a zirconia implant abutment provides a far more aesthetically-pleasing appearance once the patient’s gum needs to be considered. Additionally, it avoids the problem of trying to match the color of adjoining teeth while concealing the color of a titanium abutment.
ADVANTAGES OF ZIRCONIA IMPLANT ABUTMENTS
Zirconia In addition to its favorable mechanical properties, the material is believed to accumulate less dental plaque compared to titanium. It’s possible that the peri-implant soft tissues around zirconia may heal faster in comparison to peri-implant tissues in contact with titanium.
Concerns of strength
One of Although zirconia is very strong. It doesn’t have the same sort of strength as metal, particularly in places where the abutment could be thinner. Sometimes due to the position of the implant, the abutment must design in such a way that the axial walls may be excessively thin. If that is true, zirconia might not be a suitable abutment material. Zirconia abutments assembled as a one-piece with a metal insert. But the connection to this fixture significantly impacts the strength of the abutment. This is because the weakest portion of a zirconia abutment is in the level of the inner connection. It’s possible to achieve superior strength when using zirconia implant abutments or hybrid abutments. By utilizing an inner connection by means of a secondary metallic element.
Zirconia implant abutments can be more successful when used in regions of lower force. For example when restoring anterior teeth rather than jagged teeth, and ideally should have a secondary metal component for the inner connection to the implant. These factors must considered when designing zirconia implant abutments. Generally, the shanks of zirconia abutment screws are smaller compared to those used for titanium abutments. With a smaller diameter helps improve the performance of the relationship between the abutment and the implant. Reducing the danger of the screw loosening over time. When used in the proper clinical situations, a properly-designed zirconia abutment can eliminate aesthetic concerns when restoring anterior teeth.
