Connective Tissue Graft Versus a Porcine-derived Membrane (Mucoderm) After Immediate Placement

Esthetic outcome of immediate implant placement in fresh extraction sockets remains one of the biggest challenges in implant dentistry. Recently a method to preserve the peri-implant tissues was introduced using provisional restoration, allogenic bone and soft tissue thickening. However, the evidence that this immediate provisialisation with soft tissue grafting using different grafting materials results in constantly high Pink Esthetic scores, especially compared to the delayed loading approach is still lacking. The aim of this clinical trial is to assess the esthetic outcome of immediate temporization of immediately placed and loaded tapered implants in fresh extraction sockets with bone and soft tissue augmentation, using either a connective tissue graft (CTG) or a porcine-derived membrane (Mucoderm) in maxillary anterior sites. The secondary objectives are to investigate the influence of immediate loading on the success rate of tapered implants and crestal bone levels.
