Preservation of alveolar bone in extraction sockets using bioabsorbable membranes.
The purpose of this study was to evaluate the clinical effectiveness of a bioabsorbable membrane made of glycolide and lactide polymers in preserving alveolar ridges following tooth extraction using a surgical technique based on the principles of guided bone regeneration . Sixteen patients requiring extraction s of 2 anterior teeth or bicuspids participated in the study ( split-mouth design ) . Following elevation of buccal and lingual full-thickness flaps and extraction of teeth , experimental sites were covered with bioabsorbable membranes ; control sites did not receive any membrane . Titanium pins served as fixed reference points for measurements . Flaps were advanced in order to achieve primary closure of the surgical wound . No membrane became exposed in the course of healing . Reentry surgeries were performed at 6 months . Results showed that experimental sites presented with significantly less loss of alveolar bone height , more internal socket bone fill , and less horizontal resorption of the alveolar bone ridge . This study suggests that treatment of extraction sockets with membranes made of glycolide and lactide polymers is valuable in preserving alveolar bone in extraction sockets and preventing alveolar ridge defects
