CONCLUSION
gingiva, MARF, reduced shrinkage, Postoperative pain
DEHISCENCE
Using PRF with the MARF method significantly increased the width and thickness of the gingiva and reduced shrinkage compared to MARF without PRF. Postoperative pain scores and VD changes were similar in the test and control groups. Increasing the GT may allow PRF to be used in the presence of bone dehiscence.
