This is the lava crown which we did recently. This sixteen year old teenager fractured his tooth while scateboarding .His mom was very scared about it since it is an anterior tooth. They were worried that it may not look natural.Our dentist Dr William J Capobianco decided to go with lava crown.When dr cemented this case both patient & his mom were in tears. Of couse, they were tears of joy!!!!!. Please let us know your opinion.

这是我们最近我们完成的LAVA全瓷冠（译者注：美国3M公司的CAD-CAM全瓷系统，国内还没有开展）。该患者为16岁男孩，在滑板时21冠折。由于是颗前牙，他母亲很担心。他们担心新的的牙冠看起来不自然。我们的牙医Dr William J Capobianco决定为他制作LAVA全瓷冠。当这颗牙粘固后，患者与他的母亲喜极而泣。大家谈谈看法吧

Beautiful work!  I am just loving these Lava crowns.  I've done some anterior and posterior units, one of which was a single central similar to this case.  I think the esthetics are outstanding, they look so lifelike.  I have a case coming up with a lady with what we've determined is likely a l allegy to some old ugly  PFMs and we are going to replace them with Lavas.  Can't wait to see the results!

我也越来越喜欢LAVA全瓷冠了。做了一些前牙和后牙的LAVA冠，其中一例单个中切牙病例与你的病例类似。我想它们的美学是没得说的，看起来就象长出来的一样。我有个女患者可能对一些老的贱金属烤瓷冠的金属过敏，准备用LAVA全瓷冠替换。等着看我的结果吧！

Nat,I think in most cases the problem with l is the subgingival placement. My thought is that the allergy is much more rare than people would lead you to believe. Perhaps a little CL is in order. Perhaps not. Just something to consider.

二楼的，我想大多数病例与金属有关的问题是由于龈下边缘的原因。我的想法是金属过敏的远比人们告诉你的要少得多。（后面几句我没翻，其中的“CL”我不知道是什么意思，大家自己体会吧）

Matt, believe me normally that would be what I'd suspect.  But the margins are actually at the gingiva, and in some areas supra due to some recession over time.  They are the only PFMs in her mouth, she was one other crown that is a full gold crown and no problems there.  She developed l allergy issues over time, is very limited in the types of jewelery she can wear now.  Actually l allergy is quite common in women, especially women with multiple ear piercings.  These crowns are quite old, 25 years or more, and possibly base ls, or semi-precious at the least.  They have that ugly dull look to them that noble/high noble just doesn't have. 

三楼的Matt，相信那也是我通常会质疑的。但是这位女患者的冠边缘确实在牙龈水平，时间久了由于一些牙龈退缩某些边缘位于龈上了。那些是她口内唯一的烤瓷冠。她口内还有一个铸造金合金冠，没有问题。她金属过敏已经有一段时间了，现在只能戴用有限的几种首饰。金属过敏实际在女性中经常见到，尤其是对于佩戴多个耳针的女性。这些烤瓷冠可能是贱金属的，或者半贵金属的，使用了至少25年。它们看起来太不美观了，应该不是贵金属的。

Incredible match!!

World class stuff guys.

 

六楼ID：doctored Posted: 2/16/2007 3:18:09 AM  

Awesome Match!!!  I attribute this exceptional esthetic result to be more about the talent of the ceramist than the type of core that is veneered. Ed

太逼真了！我想这种特别逼真的美学修复更多的应该归功于技师的天才表现，而不是饰瓷所依附的内冠材料的种类。

Outstanding result!!  

I have a question/comment from a recent CE event. 

Thomas Trinkner, DDS, of Columbia, SC, recently spoke here in Cincy and made a comment about the zirconium based crowns.  He asked if we were not "over building" the system by going to this level.  His rationale was that the zirconinium is far harder and less flexible than the tooth it is protecting.  In a case of future trauma (which Dr. Trinkner has experienced with a few of these crowns) he wondered aloud whether the tooth would survive the trauma with less resulting damage to the residual tooth structure if a "more traditional" all-ceramic were used instead. 

His argument was that snapping a tooth at the gingival margin was more difficult to restore (and explain) than to have the crown itself fracture and need to be replaced. 

Just waking up and getting the first cup of coffee, knocking the cobwebs loose.  Trying to sort out things that have been said as fact/fiction or real issues to contemplate.

最近参加了一个继续教育活动，有个问题想讨论一下

Thomas Trinkner, DDS, of Columbia,最近在Cincy的一次发言中关于氧化锆基底的全瓷冠给出了一个观点。他问我们是否有必要过度的使用现在的氧化锆系统。（这句译得可能有问题，大家提提怎么译更好）。他的解释是氧化锆比它要保护的牙齿要硬得多，但是更不易弯曲。鉴于可能发生的创伤（Dr. Trinkner已经有几例发生创伤的氧化锆全瓷冠），他想知道如果替代使用一种“更传统”的全瓷冠，牙齿是否可能受到更小的创伤从而保留更久。

他认为一个在牙龈边缘水平折裂的牙齿要比冠本身崩瓷或者被替换要难处理，也更难解释。

该是醒醒，喝杯咖啡，放松一下。试着找出事实或者假设或者文献去思考了。

Thank you so much for nice comments. I totally agree with Dr Ed, that talented ceramist can match any kind of restoration with any material. Here is example of another lava crown. Enjoy . Let me know which teeth are restored. I will post before photo tommorow.

谢谢大家这么精彩的讨论。我完全同意Dr Ed的看法，那就是天才的技师使用任何材料都可以做出逼真的修复体。这里是另一例LAVA全瓷冠的图片。欣赏一下。大家猜猜哪些牙齿是修复的。明天我会贴出术前的照片。

Those are all real...no crowns in that mouth!

这些牙都是真牙吧！口内没有牙冠啊！：）

十楼ID：milapandit Posted: 2/16/2007 1:07:08 PM  

Teddy, think again. By the way, I have started new thread on this topic. Let us see how many people can guess correctly.

Teddy，再看看。顺便说一句，这个话题我又有了新的想法。我们看看有多少人能正确的猜出来。

You guys seen to do these matches incredibly good.

In the above case it could have used slightly more halo effect but even the way it is it is fantastic.

Where you guys get these technicians????

你这家伙做得这些冠好得难以置信。上面的病例使用了荧光效果但是即便这样，做得也是很棒的。你们从哪找到这些技师的？

 

十二楼ID: beowoulf Posted: 3/10/2007 1:01:59 AM  

All the work I have seen by your lab is incredible, are they working from photos or is the patient present for custom shading?

我看到的这些病例都很棒，你们是用数码照片比色还是为患者使用定制的比色板啊

Mila

Astonishing again, I prefer the guessing games with your post!

Mila, if  the lab could only use maybe 1,2 or 3 materials for anteriors and 2 or 3  for posteriors, what are their favorites. Which materials , brands of products would they choose and that they  like the best and why??

Charles  

 

楼主啊，我更想参加你的猜冠游戏。

如果技工室只可能有1种、两种或者3种材料用于前牙，2或3种用于后牙，他们最喜欢的是什么系统啊。他们会选择什么材质，哪种品牌的全瓷系统？最喜欢什么系统？为什么这样？

 

十四楼ID: deanmersky Posted: 3/10/2007 8:01:19 PM

Dennis, thanks for passing on the information from Dr. Trinkner. Zirconia has great potential, especially as seen in this case. But as Ed said, great ceramists can make a lot of materials sing. But what Dr. Trinkner is saying is only a part of what we are hearing in some corners of research. The hardness of the material at times is not a great match for ceramic where more compliant materials are able to better absorb the trauma associated with . But as with all materials, time will tell us when it will work and when it won't..

 

谢谢Dennis写出来自Dr. Trinkner的看法。氧化锆有巨大的潜力，尤其是在这个病例中。但正如Ed所说，伟大的技师可以使许多全瓷材料“歌唱”。但是Dr. Trinkner.的质疑我们仅仅在一些研讨会才可能听到。对瓷来说，材料的硬度常常不完全匹配，更适合的材料更好的吸收与功能相联系的创伤性合力。但是对于所有的材料来说，时间会告诉我们什么时候它可以，什么时候不可以。

Both centrals are restored

两颗中切牙都是修复体。

Dr Alex. Thank you so much. For  most of our cases ,we have to rely only on pictures. Majority of our clients are not local. Although, we would love to see each patient for custom shade especially single central incisor cases.

Dr Alex，对于我们的大多数病例，我们必须依靠数码照片。我们的大多数患者不是当地的。尽管我们更想为使用定制比色板来为每个患者比色，尤其是对于单颗中切牙的病例。
