Evaluation of a Poly(Lactic-Co-Glycolic) Acid-Coated β-Tricalcium Phosphate Bone Substitute for Alveolar Ridge Preservation: Multicenter Randomized Control Trial

Abstract

Purpose: The aim of this study was to determine whether the efficacy of PLGA-β-TCP in Alveolar Ridge Preservation (ARP) with histological analysis of the extraction socket following four months healing was similar to FDBA + CP as the control. Materials and Methods: 45 adult patients in this multicenter randomized controlled clinical trial were randomly assigned into treatment group A [PLGA-β-TCP] or group B [FDBA + CP] for ARP of a single extraction socket. Results: 45 bone core samples were harvested. Vital bone was present in intimate contact with the surface of β-TCP graft particles. Histologic measurements revealed no statistically significant difference between the test and control groups in percent vital bone after four months healing. Conclusion: This investigation demonstrated the similar efficacy of PLGA- β-TCP to FDBA as a bone substitute in ARP.
