The patient had composite buildups made about six years ago and these had worked off, resulting in some sensitivity.
Patient requested they be re-made.
The build-ups were then done free-hand and the incisors were treated using composite “sausage technique”.
The composite is placed across the incisors in a continuous sausage. The shape is developed with fine flat plastic from LM.
After curing, the embrasures are grooved with a very fine bur and the teeth separated by placing an instrument between the teeth and twisting it to crack the remaining composite.
Interproximal clean up is done with diamond strips and 12 scalpel.
I free-handed the buildup and then spent 15 minutes getting the occlusion right.
It is important with retention of restorations on the incisal edge to cut into the incisal dentine in order to get thickness and retention. Otherwise they are too thin and the bond breaks down as the composite splits.
