New York Times Dental Article: A Dental Shift: Implants Instead of Bridges

Hi everyone, I saw this article in the New York Times Online. Here's the teaser quote:

If I have one serious regret about my age, it is that my permanent teeth developed before New York, my hometown, got fluoridated water. I first lost a permanent molar to decay in my early 20s, and the resulting bridge has had to be replaced several times in subsequent decades, ultimately as a four-part apparatus.

Now that has to go as well. Because I could not floss and clean properly under the bridge and between the supporting crowns, I developed a severe periodontal infection.

Dr. Michael Zidile, the young periodontist I consulted, took one look at my mouth and said: “This is not how we do restorations nowadays. A bridge is not a permanent solution and makes it too hard for most people to keep their gums and underlying bone healthy. Now we do implants and individual crowns where needed.”

Zirconia and Implants

Hi everyone,


I've started the transition to using zirconia abutments and crowns with my implant cases. Why? Two main advantages:

• The silver colour of a usual titanium implant abutment (structure underneath the crown) can now be a colour that more resembles the final crown. Allows for better aesthetics. (first image)



• The strength of the crowns is incredible (reportedly up to 1200 MPa), especially compared to all-porcelain crowns with very comparable aesthetics. Allows for better durability. (second image)

Thanks to POW Laboratories for the excellent lab work. The crowns can be cemented with a temp cement (yes, the fit is that good!) or a non-expanding permanent cement. The implants that we primarily use are Noble Biocare Replace Select.


Take care
