The goal of this clinical trial is to learn if ridge preservation methods with dense polytetrafluoroethylene membranes, with d-PTFE membranes and platelet-rich plasma, and with free gingival grafts can reduce vertical resorption of the post-extraction socket walls. Researchers compared each experimental group to a control group (unassisted socket healing). Participants were randomly allocated to one of the four groups. Cone-beam computed tomography was performed after the procedure and 3 months post-operatively to evaluate the vertical socket wall resorption.

Vertical post-extraction resorption of the socket walls
Each socket wall is measured using CBCT right after the extraction and after 3 months to assess the vertical resorption.
Time frame: 3 months
