All-ceramic crowns, formerly known as “porcelain jackets,” are made from advanced generations of aesthetically pleasing, lifelike materials that provide strength and longevity compared to traditional metal and porcelain fused to metal crowns (PFM).
When a tooth needs a full-coverage restoration to restore its structural integrity and appearance, the crown’s appearance and its ability to withstand the stresses of oral function are important factors to consider when selecting a crown. Only metal crowns or porcelain crowns bonded to an underlying metal substructure provided the strength needed to bite and chew without shattering in the past. While porcelain fused to metal crowns are still a popular choice for robust, attractive, and long-lasting restorations to restore teeth that are broken, decaying, malformed, worn down, undersized, or have had a root canal, they do have some disadvantages. For instance, a PFM crown’s thin metal edge at the collar may be visible at the gumline (especially in receding gums). Porcelain fused to metal crowns also doesn’t handle light and natural tooth structure or dental ceramics due to the presence of an underlying metal shell.
Advantages Of Ceramic Scan
While it used to be the case that porcelain or all-ceramic crowns looked superior but lacked the strength and longevity of porcelain fused to metal crowns, this is no longer the case. All-ceramic crowns are capable of providing remarkably lifelike results, but they are also tougher and more reliable than ever before because of the variety of materials available today.
Some of the major benefits of ceramic crowns are:
With the variety of designed dental ceramics available in today’s time, the material chosen for crown fabrication is determined by the tooth’s location, the forces it faces, and the case’s aesthetic requirements. Some all-ceramic crowns are better suited for back teeth, while others can meet the aesthetic demands of a front tooth. Feldspathic porcelain crowns, Empress crowns, Procera crowns, Lava crowns, Zirconia crowns, and Emax crowns are some of the all-ceramic crowns used today.
