The amount of bone gain (BG) at 3 months (T1) and 6 months after tooth extraction (T2). In a post hoc test, BG in the silk mat group showed a significantly higher gain compared with the control group (nonregenerative/nongraft procedure) at T1. Both membrane groups showed significantly higher BG than the control group (nonregenerative/nongraft procedure) at T2 (*P < 0.05)
