PFM crowns have good mechanical properties, satisfactory esthetic results, and an acceptable biological quality needed for periodontal health. Let's look at this comparison on porcelain fused to metal crown vs zirconia crown, focusing on the features and limitations of each. 3) Strength- Zirconia has a 800-1200 MPA (2-3 times stronger than EMAX).
Zirconia is stronger than porcelain. Why Zirconia Crowns Are Growing in Popularity for Kids Zirconia crowns tend to be more popular at general and cosmetic dentistry practices, but they are gradually becoming more commonly seen at pediatric dental practices. Upon that the porcelain is fused. Also, it typically requires less tooth structure to be removed, although if you are replacing an existing PFM bridge, then it probably doesn't matter since the teeth were already prepared for PFM. Other methods are to mill a full zirconia bridge FP1 style that meet the implants if possible, or meets MUA abutments, or perhaps on custom abutments.
One is to fabricate individual porcelain crowns and cement to a zirconia, chrome cobalt or a titanium milled substructure.
We now have a long track record producing layered crowns and bridges.
The only thing to consider is "Zirconium Oxide Crown VS Metal Porcelain".

Summary Since 2002, ROE has digitally fabricated zirconia-based copings layered with low-fusing porcelain for . The use of zirconia frameworks for long-span fixed partial dentures or for implant-supported restorations is currently under evaluation and further in vivo, long-term clinical studies will be needed to provide scientific evidence for drawing solid guidelines. Although the crown may be worth it when fixed by a skilled dentist, they can often be the deal .
Patient has been wearing old porcelain fused to metal bridge and wanted to upgrade her style and look plus she feels that oral health has been compromised du. For most dentists, the choice between these materials is related to cosmetic and/or strength. Zirconia is a great material especially for a tooth like number 14 as porcelain can chip and fracture easier and requires more removal of tooth structure. Zirconia (Metal free crowns) has great strength and does not fracture or chip easily. The zirconia tooth crown is many times better than the porcelain-fused-metal crown - both aesthetically and in durability. Prices; Treatments. Since the bridge is made of one block of material, there cannot be teeth breaking off of a metal underlying structure because the entire implant prosthesis is made out of one block of zirconia. These special crowns can better withstand the bite pressure of the incisors and can be covered with multiple layers of porcelain to promote a more natural appearance.
The decision to use the zirconia or PFM crown must be determined by reasons other than strength alone. 2) Colour- Even though Zirconia is metal based, it has a white base color. This group is proven to make informed decisions in regards to their health and appearance. The outer esthetic layer can be accomplished with conventional powder and liquid porcelain or pressed over the ceramic coping. A Zirconia ceramic material, because of the translucency of the middle, can be as thin as 1.5mm on the occlusal and can be 1mm to 1.5mm at the axial wall, so it's an extra conservative prep than the PFM.
Zirconia crowns are made of Zirconia which is a crystal that extremely durable and practically indestructible. This delivers a better aesthetic outcome around tissue areas compared to PFM (porcelain fused to metal). 3,288.
For longevity of restorations, this weakness has to be critically considered [ 9 - 10 ]. Zirconia Layered is another extremely strong material suitable for bridges and crowns. The basic technique for porcelain and zirconia crowns are fundamentally the same regardless of the materials used to make each crown. Zirconia, or zirconium dioxide is a metal oxide that is actually a type of a dental ceramic; however, it possesses properties that are markedly different from the conventional ceramics that were being used previously. 28 CAD/CAM Zirconia Screw-Retained BridgesA CAD/CAM zirconia screw .

I have had a porcelain-fused metal (PFM) crown there for about 5 years, and my new dentist gave the option between a similar crown or a zirconia one.
With the aid of computer-assisted design/computer-assisted manufacturing (CAD/CAM) technology or copy milling, zirconia is currently used in implant prosthodontics for the fabrication of implant abutments, single crowns, fixed dental prostheses (FDPs), and complete arch frameworks. Both zirconia and all-porcelain crowns are biocompatible. 27 If a chipped prosthesis needs to be repaired after delivery, addition of porcelain can be problematic, and usually requires intervention by the dental laboratory.
Porcelain fused to zirconia (PFZ) crowns and bridges can serve as a CAD/CAM alternative to the traditional porcelain fused to metal (PFM) restorations. Conclusions: Keating Dental Lab's porcelain-fused-to-zirconia crowns and bridges provide the perfect blend of handcrafted aesthetics and digitally produced precision. Studies that reported long-term results were found only for the MC crown group.
