Soft tissue grafting at immediate implants: does it protect the buccal plate?
Abstract
Jung M, Tran D, Chang CC, Kim SK, Tsukiboshi Y, Min S, Ayilavarapu S, Lee CT. Volumetric buccal bone alterations at immediate implant sites with or without soft tissue augmentation: A 6-month assessment. J Periodontol. 2026;97:220–33. https://doi.org/10.1002/jper.11381. This was a secondary analysis of cone-beam computed tomography (CBCT) and scanned model data from a registered randomised controlled trial evaluating immediate implant placement with or without soft tissue augmentation1. The study compared immediate implant placement with subepithelial connective tissue grafting, immediate implant placement with acellular dermal matrix, and immediate implant placement without soft tissue augmentation (control). Forty-five patients requiring extraction of a single maxillary anterior or premolar tooth followed by immediate implant placement were included. Participants were allocated to one of three groups: immediate implant with subepithelial connective tissue graft, immediate implant with acellular dermal matrix, or immediate implant alone. In all groups, the gap between the implant and the alveolar bone was filled with bovine bone material and a collagen dressing was placed. CBCT scans were taken before extraction and 6 months after immediate implant placement. The scans were superimposed to assess three-dimensional volumetric and two-dimensional linear buccal bone dimensional changes. The buccal region was divided into coronal, middle and apical thirds. Volumetric bone loss…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
