Abstract
Objectives: The aim of this study was to compare the clinical and radiographic outcomes of the socket shield technique (SST) versus the modified socket shield technique (MSST). Methods: twenty patients were included in this study for replacement of a single non-restorable maxillary tooth in the aesthetic zone by dental implant. Patients were randomized into two equal groups. In the first group A, implants were treated by SST with immediate implant placement, while in the second group B, implants were treated by MSST with delayed implant placement. All patients were evaluated clinically and radiographically at implant placement time, loading time and 6 months after loading regarding implant stability, peri-implant pocket depth (PPD), modified sulcus bleeding index (mSBI), esthetic outcomes by pink esthetic score (PES) and marginal bone loss (MBL). All clinical and radiographic data were subjected to statistical analysis. Results: During follow up period, all patients showed favorable clinical and radiographic finding. There were no significant differences between the two groups regarding implant stability, mSBI and MBL at any time interval. However, it was shown that group A had a significant higher PES than group B at loading time only. However, at 6 months after loading there was no significant difference in the mean PES between groups. In addition, there was a significant difference between groups concerning the mean PPD values at loading time and at 6 months after loading. Conclusion: Both SST and MSST demonstrated better preservation of alveolar bone structure and peri‐implant tissues, facilitating better functional and esthetic outcomes particularly in the esthetic zone. Subsequently, it is recommended that selection between these two techniques depends mainly on patient selection criteria.
