Changes of Soft Tissue Grafting: A Randomized Study

April 23, 2026 updated by: Tufts University

Volumetric Changes of Soft Tissue Grafting. Comparison of Autologous PRF (Platelet-rich Fibrin ) & Autogenous CTG (Connective Tissue Grafts) . A Split-mouth Randomized Design

To correct gum recession, patient's own tissue from the roof of the mouth is harvested and placed where there is root exposed. This is considered gold standard of treatment. Sometimes patient don't want to have second surgical site in their mouth and at the same time do not want to use alternative tissue from human or animal donor. Using patients' blood and preparing it as a membrane is the next best thing to correct gum recession.

Detailed Description

Patients that are interested in having corrective surgery for recession due to esthetic concerns or sensitivity will be enrolled in the study. The treatment site will randomly receive the procedure assignment. Intraoral scanner will be utilized to establish pre-op volume and will be repeated at each follow up visit. Total of 12 visits and 5 year duration is anticipated for the study.

  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: All Participants
Participants will receive the CTG procedure on one side and the PRF procedure on the other. Both are standard of care soft tissue grafting methods and a split mouth design is standard of care.
PRF on one side of mouth and CTG on the other side of participant's mouth.
