Evaluation of Immediate Dental Implant Augmented with Biphasic Calcium Phosphate Coated by Polylactide - co-Glycolide Versus to Immediate Dental Implant Only

Abstract

Objectives: Numerous bone grafts have been studied for augmentation of the healing outcomes of dental implants. The aim of this study was designed to compare the clinical and radiographic evaluation between immediate dental implant augmented with biphasic calcium phosphate (BCP) coated with polylactide -co-glycolide (PLGA) and immediate dental implant alone. Materials and Methods:Twenty adult male patients with endodontic failure, root fracture, decayed tooth, retained deciduous teeth and teeth with internal/external root resorption were selected and categorized into the followings; Group 1(G1); received immediate implant only and group 2 (G2); received immediate implants augmented with (BCP/PLGA). The patients were evaluated at baseline, 6 and 12 months, clinically; by using plaque index (PI), gingival index (GI) and Pocket depth (PD). In addition, radiographic evaluation of marginal bone level (MBL) and measurement of bone density (BD).Results: Clinical improvement of GI and PI were observed in both groups, the statistical analysis were non-significant in comparisons at different time intervals. PD was significantly reduced in G1at 6 months versus baseline and highly significant at 12 months compared to baseline, in G2 the comparisons at 6 and 12 months contrast to baseline was highly significant, and whereas the differences at 12 months were significant reduced in G2 than G1. Radiographically, MBL was showing highly statistical significant in comparing the baseline versus 12 months in both groups, but at the difference at 6 months compared to baseline was highly significant in G1, while insignificant in G2. Moreover, there is no significant difference in G1 against G2 at 6 and 12 months. In addition, the bone density was showing highly statistical significant in comparing the baseline contrast to 6 and 12 months in both groups, and highly significant differences were observed in G2 compared G1at 6, and 12 months. Conclusion: Immediate dental implant augmented with BCP/PLGA achieved significant improvements in clinical and radiographic outcomes rather than immediate dental implant only.
