Effect of L-shaped, loosely packed versus non-trimmed, compactly packed non-fixed collagenated bone blocks on the stability of augmented sites in chronic peri-implant dehiscence defects: a pre-clinical in vivo experimental study

Year: 2025

Type: article

Abstract: PURPOSE: This pre-clinical study aimed to compare the efficacy of L-shaped, loosely packed soft block bone substitutes (BBS, LP group) with that of non-trimmed, compactly packed soft BBS (CP group), both covered with a non-fixed collagen membrane, on augmentation stability and new bone formation in chronic peri-implant dehiscence defects treated with guided bone regeneration (GBR). METHODS: test. Bland-Altman and Spearman correlation analyses were also performed to evaluate the relationship and agreement between micro-computed tomography (micro-CT) and histomorphometric measurements. RESULTS: <0.001), supporting the reliability of radiographic methods for bone assessment. CONCLUSIONS: Neither LP nor CP soft BBS effectively prevented morphological collapse in the coronal region of augmented sites when used without additional membrane fixation. These findings underscore the necessity of enhanced stabilization techniques to improve structural integrity and bone regeneration in GBR procedures.
