Talk:Crown (dental restoration)

Reasons to restore with a crown.
I came to this article because I wondered why a person would need a crown (not because I wanted to know what a crown is). From the introduction, all I can gather is that they cap or encircle a tooth (or dental implant) to improve the strength or appearance of said tooth (or dental implant).

The first section is titled "Other reasons to restore with a crown", but I'm left wondering what the primary reason is. As this article concerns teeth (something which almost all readers of wikipedia probably have and occasionally think about), I think this article might be improved by assuming a bit less prior knowledge, and explaining the necessity of a crown outright.

I will happily read (elsewhere) about crowns and subsequently make these changes myself, but if anyone else with previous understanding or experience would like to contribute suggestions, or an outright rewrite, I welcome them.

Chip, the second sentence of the article states "Crowns are often needed when a large cavity threatens the ongoing health of a tooth" - This is the primary reason. —Preceding unsigned comment added by 69.113.98.195 (talk) 23:29, 18 October 2010 (UTC)

I'm the one that added that. Chip McShoulder (talk) 21:19, 10 December 2010 (UTC)

CAD/CAM Dentistry, Restorative Materials
I am probably picking nits, but I would rather see the term CAD/CAM Dentistry exchanged for CAD/CAM Dental Laboratory Work, or perhaps CAD/CAM Fabrication. The reason I did not edit the main article is that it is debatable. The reason I brought it up is that computers do not do the actual dentistry, they do the dental laboratory work of fabricating the restoration.

Further, other materials might be explored, as I am sure some of my more learned colleagues may be able to cite journal articles regarding lithium disilicate. I prescribe it often for my patients, as I know its physical properties and clinical use, but I do not have articles to cite. Thanks! Jedaniel (talk) 19:36, 20 October 2010 (UTC)

History of crowns
I would like to see a history of the prosthetic crown. And who invented it, etc.

thank you. —Preceding unsigned comment added by 75.20.188.220 (talk) 03:31, 3 March 2011 (UTC)

Longevity
Wait...why is CEREC not mentioned in longevity when it might be the best option? http://www.drsimonrosenberg.com/cerec_research.html —Preceding unsigned comment added by 24.14.167.165 (talk) 16:01, 5 March 2011 (UTC)

Dental crown may refer to normal anatomy not just a restoration.
I would say that the original anatomical meaning of a crown is that part of a tooth which is above the gingiva. Surely this should be defined in the article? Maybe hatnote? Lesion ( talk ) 17:30, 14 February 2013 (UTC)

 * Can't see any reason that it was deleted. Restored unless the person removing it can give a good reason. Lesion  ( talk ) 21:57, 26 June 2013 (UTC)

Citation for fracture rates
I couldn't find the "Clinical Fracture Rates for Nonvital Teeth" figure in the citation (Carbon fiber reinforced root canal posts. Mechanical and cytoxic properties, Eur J Oral Sci 104:605, 1996). Where did this figure come from? Elem3nt (talk) 19:25, 29 May 2014 (UTC)
