Long-term clinical performance of flapless implant surgery compared to the conventional approach with flap elevation: A systematic review and meta-analysis

Figure 5 Forest plots of the results of subgroup analyses to compare long-term clinical performance between the guided/free-hand flapless surgery subgroup and the conventional surgery group. A: Implant survival; B: Marginal bone loss; C: Complications. The sample size of each research group in each study varied slightly for different outcomes due to missing data.
