UNSUPPORTED ENAMEL!
​
We could have all left Op1 lecture much sooner last Tuesday morning if any of the students had figured this out. We assistant professors in the back of the auditorium had our fingers crossed! But just repeating a phrase without understanding what it means won't help anyone succeed as an operative dentist. Perhaps it's hard to understand enamel - and its need for support - when the teeth you treat are plastic. (I must add that after yesterday's lab assignment, the concept of unsupported enamel is already making more sense!) ​So let's dive into the textbook definition of unsupported enamel and see how it relates to the all important concept of margin strength in tooth preparation.
