The Effect of Defect Morphology and Membrane Fixation on 3D Graft Material Displacement During Primary Wound Closure in Horizontal Bone Augmentation-An Ex Vivo Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThis preclinical study evaluated the influence of two defect morphologies on graft material displacement (GMD) during primary wound closure in horizontal bone augmentation (HBA). Secondary aims included assessing the effect of membrane stabilization and the role of local soft tissue characteristics on GMD. MATERIALS AND
methodsStandardized HBA procedures following guided bone regeneration principles were performed on fresh pig hemimandibles. Each mandible received two sequential HBAs, randomized for defect morphology-partially contained (PCD) vs. contained (CD)-and membrane stabilization with (+Pins) or without (-Pins) four fixation pins. GMD was assessed using cone-beam computed tomography and intraoral scanning by comparing graft dimensions before and after wound closure, at nine levels from the implant platform and across nine delimited sections, respectively.
resultsSixty HBA procedures were analyzed. A notable GMD was observed for both PCD and CD, with no significant differences between them. In contrast, membrane stabilization significantly reduced three-dimensional GMD across all sections, with the most pronounced effect in the central-crestal section (p < 0.001). At the implant platform level, GMD was -15.8% ± 25.6% with pins vs. -38.1% ± 27.4% without pins (p < 0.001). Across all groups, GMD occurred in an apico-lateral direction, with the greatest volume loss in the central-crestal, mesial, and distal crestal sections. Soft tissue phenotype did not affect GMD (p ≥ 0.240).
conclusionDefect morphology did not significantly influence the notable apico-lateral GMD. However, membrane stabilization using pins effectively reduced graft displacement, minimizing movement during primary wound closure.
