Abstract
INTRODUCTION: This study evaluated the efficacy of a resorbable l-lactide-ε-caprolactone copolymer (PLCL) membrane in promoting epithelial healing and preserving alveolar bone morphology using the open healing approach (OHA), compared to conventional membranes. METHODS: Extraction sockets in beagle dogs were filled with bone substitute material and covered with different membranes. Healing was assessed via histological analysis and micro-CT imaging. RESULTS: The PLCL membrane reduced bone resorption and preserved alveolar bone morphology better than conventional membranes. Histological analysis showed excellent epithelial healing and notable bone formation. CONCLUSIONS: The PLCL membrane effectively prevents infection, supports epithelial healing, and preserves alveolar bone morphology in OHA procedures.
