CEREC Failures

CEREC crowns do not fail more often than traditional crowns. Any crown will fail if it is not designed properly. The crown must fit the bite both when the teeth are closed and in function. The tooth must be prepared to provide enough thickness for the crown to maintain structural integrity. The margins of the crown and tooth preparation must be matched so that a proper seal exists, even before cementation. Home care is also an important factor, since a healthy... more

CEREC crowns and longevity--NOT GOOD

In the hands of a skilled and competent dentist, CEREC crowns and onlays/inlays work well. However, I see alot of people coming in with poorly done CEREC restorations. It seems as though there is a steep and long/tall learning curve. Some dentists do not seem to ever get thru the learning curve. Quite often they are poorly cemented with gaps at the margins or excess cement that cannot be cleaned off. I also believe there is tendency of dentists to overprescribe CEREC crowns when a direct... more

CEREC Crowns

With todays technology, a skilled dentist using a CEREC machine will be able to fabricate a crown that is equal to any lab fabricated crown. In fact there are many labs that are now utilizing CAD-CAM technology to fabricate their crowns. The real factor to the longevity of the crown, if done well, is the home care and habits of the patient.

Cerec crowns and restorations are great, but...

I have found over time that the most predictable type of restoration is one made out of gold. However, many people these days dont want metal in their mouth. Gold is almost unbreakable and can be cemented in with a traditional easy to use cement. Cerec crowns are made out of porcelain which is in most cases not as strong as gold. Cerec also must be bonded rather than cemented, which means that it requires more steps that have to be followed very carefully. ... more

Is Cerec crown as long lasting as a traditinal one?

There is no set life time for ANY Restoration. I have seen 20 year old crowns that still are good, and I have had patients coming in with a prior crown that was less than a year old and was failing. Same thing goes for cerec, all porcelain , gold, whatever crowns ! That is because there is so much involved , and variety of factors. Such as laboratory used, expertise of the dentist, " bite issues", clinching, grinding, crowding, the extend of disease on the tooth, hygiene.... more

Cerec failures

The lifespan of a cerec or any type of crown really depends on the patient and the dentist. If the dentist is being very meticulous with the occlusal components, the life span is longer. If the bonding process is followed to the exacting specifications that are indicated, then you will get a better result. If the patient does not keep good homecare and does not visit the dentist regularly then the reults will be less predictable. It does seem that lots of education is needed for dentists to... more

Cerec crowns longevity and survival

Cerec is a great product with amazing software potential. However, originally created for inlays/onlays they widened their makret by pushing Cerec crowns, "same day crowns" for general dentists. Milled Cerec crown which is done in the office and usually not even glazed in the oven, is t immediately cemented on the patient`s tooth. There is no underlying research showing that Cerec milled restorations strength, long-term success can be compaired to lab-produced metal or zirconia... more
