Purpose: The purpose of this randomized, controlled split-mouth study was to compare the behaviour of the extracellular matrix membrane with autogenous subepithelial connective when used as a biological barrier in the covering of immediate implant placement after modified edentulous ridge expansion. Materials and Methods: A total of 5 patients aged between 40-59 years (3 males and 2 females) were selected for this study, and were randomly assigned to one of the 2 groups: extracellular matrix membrane or autogenous subepithelial connective. A total of 29 screw-shaped titanium implants were inserted. Control (Subepithelial connective tissue graft (SCTG)) or test (extracellular matrix membrane (EMM)) treatments were randomly assigned at the same surgical appointment. Clinical examinations and prophylaxis were performed in recall sessions at 2, 4 and 16 weeks post-surgery. A soft tissue biopsy was performed at both sides 4 months post-operation. Results: This study indicates that both procedures were effective and predictable in barrier membrane coverage after bone expansion and immediate implant placement. Conclusions: The use of EMM may be a valid alternative to SCTG as a biological barrier in bone expansion procedure. The use of the extracellular matrix membrane eliminates the need for the palatal donor site and, as such, provides a surgically less invasive solution.
