Clinical and Dimensional Outcomes of Sealing Socket Abutment Combined to Alveolar Ridge Preservation

Belgium20 participantsStarted 2018-08-22

Plain-language summary

objectives The aim of this study was to assess the implant outcomes as well as hard and soft tissue dimensional changes of immediate implant placement in posterior sites using a custom-made sealing socket abutment (SSA) combined to alveolar ridge preservation (ARP). Material and methods Twenty posterior teeth were immediately replaced with implants in 20 patients. The remaining sockets were filled with Deproteinized Bovine Bone Mineral. Based on intra-oral scanners (IOS), custom-made SSAs were placed the same day. CBCT and IOS were performed to monitor hard and soft tissue dimensional changes. Moreover, implant survival rate, peri-implant bone changes, peri-implant health and pink esthetic score were recorded at 1 year, 3years and 5 years.
