Clinical Outcome of Submerged vs. Non-Submerged Implants Placed in Fresh Extraction Sockets
The aim of this study was to compare the clinical outcome of submerged vs. nonsubmerged tapered implants placed into fresh extraction sockets. The results showed statistically significant differences between the two groups in the mean value of keratinized tissue (KT) height after surgery that was significantly reduced for submerged implants when compared with transmucosal implants. Similar outcomes were found for submerged and non-submerged implants placed in fresh extraction sockets with a horizontal peri-implant defect smaller than 2mm, except for a reduction of KT in the submerged group. Either with a submerged or a nonsubmerged procedure, 1mm of mean soft tissue recession is seen after 1 year when compared with the pre-extraction situation.
