« 4 Implants in the Mandibular Anterior Area? | Internal Vs. External Hex? »
Keith from California asks:
I have the impression that, in absence of aesthetic considerations, gold crowns are superior to PFMs on natural teeth and on dental implants. Is this accurate?
Also, can gold crowns be used on free-standing, single-tooth and
mini dental implants? Are there any contra-indications to using gold crowns for this purpose?

if esthetics dose not come in to picture,precious gold crowns restorations are THE BEST REGARDLESS OF TYPE OF RESTORATIONS,INLAY,ONLAY,SINGLE ,MULTIPLE,NATRAL TOOTH, IMPLANTS, MINI,MICRO,WIDE.
Agreed gold endures forever. I have never had a gold crown that we have made chip or crack.
If you can place a crown you can use a gold one…. to me the best when there is no esthetic consideration
Gold is premier restorative material if aesthetics is not a factor. A gold onlay is my choice for over 5 decades since it does not disturb the buccal and lingual gingiva.
When asking what is best,,ask best for what. The only negative to gold is esthetic considerations. Or galvanic issues, which are usually not long lasting. To me besides longevity is its wear rates in the oral environment.It has the properties of wear not so different from tooth structure. This is called adhesive or smear wear, like enemal. This is very important for our implant supported restorations. We want them to wear at similiar rates as tooth substance so that the occluding surfaces are more maintainable over time. Harder materials , more brittle materials have different wear qualities such as abrassive wear which will damage tooth substance. In a nut shell a feldspathic restoration can be left high on the bite by having a slower wear rate than gold vs. tooth material. I use gold when ever I can. The wear properties are great. It also lends it self to have a better energy loss coeficient and a degree shock absorption.It will also lend itself to screw retained systems better than ceramic of any form.
If esthetics is not a concern, use a gold crown. It is the most durable restorative material, and it will not prematurely wear the opposing teeth or restorations.
Gold for posteriors is Gold standard.
PFM is good for the rest of the mouth, depends the quality of the porcelain, strength, coefficient of thermal expansion of porcelain to metal.
Don Cornell and many others do awesome work with PFM.
I believe we the use of all ceramic is good for single units or 3 units.
More studies and research is necessary before we go with the flow with companies pushing use full mouth zirconia(procera) , research show the are brittle and have high crack propogation.( why you think they came up with Nobel Rondo recently)
Porcelain can’t stick to the thing.
I wouldn’t run and do full mouth Dicors and have them all crack,and have a pretty upset patient.Case selection counts when and where in the mouth.
I hope this helps.
