As many of you already know, I'm studying to become a dentist! This morning I had my final operative summative that involved a MOD Class 2 Composite on tooth #19!
What makes this restoration difficult is breaking contact on both the medial and distal aspects of this molar. We call the method "dropping the box", where we drill our burs into the medial and distal marginal ridges forming a sort of rectangle. Then we precede to flaring out the walls of that opening and smoothing the floors and walls of the box!
We then Prime, etch, and seal the preparation with composite! This restoration was done on ivory, so we don't focus much on matching the composite shade with the tooth. On natural tooth structure, you wouldn't be able to notice you had a restoration on that tooth!
I'm super happy because I got a near perfect score for this summative! The next time I do one will be on a real patient!
