Objective: Test the clinical efficacy of permamem® in alveolar ridge preservation
To obtain preliminary data and test the clinical effectiveness and efficacy of permamem® (d-PTFE membrane) in alveolar ridge preservation procedures with a flapless approach.
Socket sealing with intentionally exposed permamem® without socket grafting
A traumatic extraction was performed in the premolar maxillary area of 15 patients, and permamem® was used to seal the alveolar cavity: no biomaterial was used to graft the socket and the membrane was left intentionally exposed and stabilized with sutures. The membrane was removed after four weeks and dental implants were placed four months after the procedure. After 4 months the ridge width and height and keratinized mucosa width were measured.
Stable bone ridge width and height after 4 months
After tooth extraction, healing was uneventful and membranes were removed non-surgically without anesthesia after four weeks. No bacterial infection was detected in any of the cases treated. The mean width of the alveolar cavity was 8.9 ± 1.1 mm immediately after tooth extraction, while four months later a mean reduction of 1.75 mm was experienced. A mean vertical reduction of 0.9 ± 0.42 mm on the buccal aspect and 0.6 ± 0.23 mm on the palatal aspect were recorded at implant placement.
