Generation of pre-liminary data and testing the clinical efficacy of a novel non-porous d-PTFE membrane.
Traumatic maxillary tooth extraction in 15 patients. Covering of empty sockets with permamem®, intentionally left exposed. Membrane removal at four weeks. Evaluation of dimensional changes of ridge width and height after 4 months.
Mean width of alveolar cavity 8.9 ± 1.1 mm after extraction; at 4 months a mean reduction of 1.75 mm. Vertical reduction of 0.9 ± 0.42 mm on the buccal aspect and 0.6 ± 0.23 mm on the palatal aspect at implant placement.
permamem® is not affecting the regeneration despite membrane exposure. The new non-absorbable membrane proofed to be highly effective in alveolar ridge preservation.
