Porcine collagen matrix

Comparison of soft tissue volume changes following connective grafting

A new study has compared different tissue grafting approaches to evaluate the changes in peri-implant soft tissue volume. The German study compared subepithelial connective tissue grafts with porcine collagen matrices.

Peri-implant soft tissue thickness is particularly important in the aesthetic zone. Soft tissue grafting is often used to reduce gingival recession and lower the risk of peri-implantitis. Subepithelial connective tissue grafts (SCTG) in the palate are often considered the ‘gold standard’ in this regard. An alternative method involving the introduction of a porcine collagen matrix has been suggested as a way to avoid tissue loss.

The study involved patients who had received implants in the aesthetic zone with a buccal tissue deficit. The patients’ soft tissue was thickened using a SCTG or a collagen matrix. Optical scans were taken before the procedure, at the point of surgery and at six months following.

The results showed that the SCTG group had higher soft tissue gains compared with the porcine collagen matrix, suggesting that SCTG is the procedure which will lead to the most favourable outcomes.

This study was presented as an e-poster at the 2018 EAO Congress.
