• Resumen

  • Background: The aim of the present study was to radiographically evaluate the vertical socket walls changes, and the peri-implant marginal bone remodelling, and clinicallly the soft tissues conditions around the non-submerged single implants placed into the inter radicular septum of mandibular molar sockets, associated with a collagen membrane, after 3 years of loading.Material and Methods: Thirty patients underwent to placement of a non-submerged implants with a laser-micro-textured collar into the inter radicular septum of mandibular molar fresh extraction sockets. A collagen membrane and the mucoperiosteal flap were adapted around the neck of the implants, leaving the laser-microtextured collar to heal in a transmucosal fashion. Results: At the end of the follow-up period, no statistical differences were found for each radiographic measure-ments used for the examination of extraction sockets vertical bone changes. Compared to implants placement, at the end of the 3-year follow-up, the vertical radiographic mesial and distal peri-implant marginal bone levels showed a statistically significant gain of 0.9 (SD 0.5), and 1.0 mm (SD 0.6), respectively (P=0.037).Conclusions: in mandibular fresh extraction sockets, the method of GBR around transmucosal implants with la-ser-microtextured surface placed into the interadicular septum may be used successfully to counteract the ridge remodelling.
