“What is the strongest crown for teeth?”
I am a 35 year old male and I will get a dental crown. What is the strongest crown for teeth?

BruxZir® solid zirconia crowns have been known to have the highest strength and durability. Full gold crowns are also considered the best crowns, the only issue with FGC is they're not esthetically pleasing to some patients due to the gold color.
It really depends on what is wrong with your tooth. The more of your original tooth that remains the more support it can give to the material that is replacing the lost tooth. A veneer can increase the strength of the tooth if prepared correctly. Newer glass ceramics can have a similar impact depending on the remaining tooth it is bonded (glued) to.
Gold.
The strongest crown for a tooth is a metal (gold) crown for the back and a Zirconia (tooth colored) Crown for the front. You may not need the strongest material in all areas of the mouth, especially in the front where aesthetics matter more. We recommend Emax ceramic crowns in the front teeth where looks and strength matter the most.
Zirconia
We now have many materials to choose from. Gold is still the longest lasting and most durable. But if the tooth is visible many people want porcelain crowns which look and feel like real teeth. It depends on what your goals are for the tooth that needs a crown.
One made of Zirconia.

It's not a simple answer. It depends on which tooth it is and why it is being restored. The longest lasting, most bio compatible and strongest crown would be gold. Obviously, most people would not want that on a front tooth. Gold crowns that I made have lasted 30 to 50 years. Porcelain crowns can crack and chip in 3-5 years. Zirconia can be very strong and has pros and cons. The question can only be well answered with X-rays and models and a bite registration.

The strongest crown would be a non-precious metal crown. These are also, generally, less expensive. The drawback is the appearance is silver or chrome colored in nature.
The next strongest would be type III gold. It has a very good, long track record has a dental restoration. The drawback is the price of gold has become very expensive, and the color of the tooth would be gold.
The third strongest would likely be zirconia. The original form of zirconia (3Y) is strong but the color tends to be very white. This is least objectionable for back teeth. It is hard to get an acceptable match for front teeth with 3Y zirconia. The concern of this restoration is future replacement is more difficult due to the hardness (cubic zirconia is man-made diamond material). It is closer in color to natural teeth then the silver or the gold and may wear the teeth it chews against faster than desired.
The 4th strongest crown material is the modified zirconia (5Y) which is more translucent and can be colorized to be very similar to natural teeth. Equal in strength to 5Y zirconia is lithium disilicate that goes by the trademark e.max. There are other companies that also make lithium disilicate, but e.max by Ivoclar is the originator. These look very much like natural teeth and are similar in hardness to natural teeth.

For decades the strongest crown for molars was always a GOLD crown. Today there is an alternative, Zirconia is a white material that is extremely strong it can be done using the new 3D scanners and printers and it will last over 20 yrs. if you clean it properly
Either all gold if a back tooth or else ask for the nonmetal brand Bruxzir.

Hello,
Dental materials are always changing and this is an area of focus right now. Strength is an interesting concept. The strongest 1 piece crown right now is the full strength zirconia crown. In my opinion, the only thing that compares to this would be a full metal crown, but then it will never match your teeth. Is strength the only thing you want to consider? If it is in the front, then would you be interested in aesthetics as well? Anyway, the majority of the ones I do are full-strength zirconia crowns.
Hope this helps!
My best to you!

Depends on your personal situation. Molars usually do well with zirconia or PFM crowns. Premolars and incisors (front teeth) are usually fine with eMax or PFM crowns. If your are a bruxer (grinder/clencher) you may want only zirconia, whether molar or incisor.
