The Good Crown
There are many types of crowns available and they are described on my web site (www.focusedcaredental.com). I go into details on all of them. What is not explaided by most of the profession is the part of the crown that is the most critical. In dental-speak we call that area the margin. That is where the crown comes togeather with the tooth. The Americal Dental Association says that opening can be up to 40 microns. We have no way to actually measure such a tiny space before or after the crown is actually cemented. I like to take a fine pointed instrument called an explorer and run it over the margin before the crown is cemented and feel by touch and lots of experience if there are any openings. Sometimes an x-ray is called for as at times it will show the opening if I feel a gap, and sometimes not. It a discretionary call. The secret here to achieve a durable crown is a very good mold of the tooth and a great dental technician. We have both. With that combination , I estimate that 95% of the crowns that are done in my Encino dental office meet or exceed the standard. If not, we do it again.You can trust me that my 95% number is far, far above the average. I always try to give you my best effort.
Tip of the day: One, if the dental assistant is taking the impression it is likely agaist the law and two, I consider that to be second class care. Best regards, AM
