Lateral alveolar ridge augmentation with autogenous block grafts fixed at a distance vs resorbable poly-D-L-lactide foil fixed at a distance: 5-year results of a single-blind, randomised controlled trial.

Purpose: To report the 5-year outcomes of autogenous bone block grafts fixed at a distance (BBG-D) versus a resorbable poly-D-L-lactide foil fixed at a distance (SonicWeld Rx shell technique [SWST]) randomised controlled trial, for lateral alveolar ridge augmentation.

Materials And Methods: Thirty patients with a buccopalatal bone width of ≤ 3 mm were randomised into the following treatment groups: BBG-D and SWST. The implant survival, changes in bone morphology visualised in a cone beam computed tomography scan and periodontal parameters were assessed.

Lateral alveolar ridge augmentation with autogenous block grafts fixed at a distance versus resorbable Poly-D-L-Lactide foil fixed at a distance: A single-blind, randomized, controlled trial.

Objectives: The aim of this study was to compare bone block grafts fixed at a distance (BBG-D) with the SonicWeld Rx shell technique (Poly-D-L-Lactide foil fixed at a distance, augmented with autogenous and deproteinized bovine bone particles (SWST)) for lateral alveolar ridge augmentation.

Methods: In this single-blinded, randomized, controlled trial, 30 patients with a bucco-palatal bone width of ≤3 mm were randomized into the treatment groups: "BBG-D" and "SWST". Bone width was measured with cone beam computed tomography (CBCT).
