Composite Resin
3. The plastic U-shaped frame is placed the dam; the metal Young frame and the
Ostby frame are placed the dam.: Under; Outside
4. The primary advantage of non-eugenol periodontal surgical dressing over periodontal
surgical dressing that does contain eugenol is that: Some pa- tients are allergic to the eugenol

same arch: Contact Area
