What type of dental implant crown is the strongest on molars. lab made all porcelain, the cerec crowns, pfm or pfhnm crowns. which ones are worst.

Gold crowns: For strength and longevity, gold would be your best choice, for esthetic reason we use porcelain, zirconia is the strongest but it is very abrasive and can damage the opposing teeth, e_max blocks (cerec), or pfm should do well, in this case e_max, can be stronger then the regular pfm, but again it can be a bit more abrasive. The choice is yours.

Varies: Depends on the location of the tooth and the forces and alignment. If esthetics is not a concern, the zirconium is the strongest. The pfm or pfhnm is the most esthetic. I would not choose all porcelain. Cerec can be strong, depending on the material used. Good luck.

Ask dds: Your dentist can examine your mouth and the opposing teeth to determine which kind of crown is best for you.

Alloy: The strongest crown would be a gold crown. The next would be an all zirconia crown. The weakest an all porcelain crown with no substrate.

Zirconia: We like to use zirconia crowns, but there is no best one. Metal ceramic crowns or all metal crowns need to be used somethimes, so have your dentist choose for you.

PFHNM: Porcelain fused to high nobel metal are probably the best because the underlying metal substructure can be designed to support the porcelain adequately. The worst would probably be cerec because can not get an adequate seal at the margins.

Strongest =all metal: All metal crowns are without a doubt the "strongest" restorations. Feldspathic ceramic (original cerec porcelain) and original "cosmetic " all ceramic crowns are the weakest. However a "strong" artificial crown may, abrade or otherwise unforgivingly traumatize an opposing natural or artificial tooth. The choice of a "strong" crown does not equated to the most appropriate crown.

Zirconia: While an all metal crown may not break it can be worn through over time. A zirconia crown will last longer and be more cosmetic than a metal crown.

Metal is the : Easy answer for strongest. You can have a full contour titanium crown! but who wants a metal crown anymore? Zircon material (bruxzir) is the strongest ceramic style tooth colored/ shaded choice and I use this almost all the time.

Consider this: Years ago, we would place all metal (gold), but no one wants that anymore. Strongest is bruxzir (all zirconia) -- for molar this would be "aesthetic" enough. These are actually metal, but look like all porcelain, although they do not have the life-like translucency that porcelain has. But for a molar they work quite well and do not abrade the opposing tooth to the same extent as porcelain can.

Strong?: Strong in what sense? Each crown material has its own indication. We want to use a material that is comparable with natural dentition. In some cases for example in bite situations that are less than ideal, a very strong material like zirconia can be harmful to the opposing teeth. So different situations calls for different material. Consult a dentist or a prosthodontist.

Gold is #1: Although expensive these days, gold crowns are the strongest available. For those wanting a more natural look, a solid zirconia crown is strongest but may wear down the opposing teeth quicker. Third strongest would be zirconia layered with porcelain or porcelain veneered or bonded to metal. This is a great question. The least strongest would be cerec-type crowns not made of zirconia.

All Zirconia or gold: I believe the strongest implant crowns made are all zirconia, or bruxzir crowns. They are virtually chip proof. They have the advantage of being tooth colored. A high noble full cast gold crown is also an option if esthetics are not a concern for you. If you are not a clenching and grinding your teeth, any crown can work. I you do clench, avoid base metal porcelain fused to metal crowns.

Bruxier or All-Cast: While there are so many options for implant restorative crowns, probably the strongest in the molar region would be the new "bruxier" one piece crown or a full cast implant crown. Probably screw retained would be ideal, but as long as the abutment cement is completely cleaned out these two types of crowns would be least likely to fracture.

Gold: A metal crown is going to be the strongest in most cases.

Dental implant crown: They come in many sizes and shapes and some are appropriate in some areas and not in others. Todays ceramics that are milled such as zirconia and lava type crowns are generally as strong as metal crowns provided there is sufficient thickness of material. Pfm crowns may be the one at risk for fracture as an implant has not movement like a natural tooth and you need room for metal and porcelain.
