 # When the flaps are not in close apposition, following suturing technique is used:

A. Direct or loop suture

B. Sling ligation

C. Anchor suture

D. Figure of 8 suture

The correct answer is D. Figure of 8 suture.

Interdental Ligation. Two types of interdental ligation can be used: the direct loop suture and the figure-eight suture. With the figure-eight suture, thread is placed between the two flaps. This suture is used when the flaps are not in close apposition as a result of apical flap position or nonscalloped incisions. This is simpler to perform than the direct ligation. The direct suture allows for a better closure of the interdental papilla. It should be performed when bone grafts are used or when close apposition of the scalloped incision is required.
