Summary:
In patients requiring posterior tooth extraction with immediate implant placement, chairside composite Sealing Socket Abutments (CS) significantly reduced volumetric tissue shrinkage compared to prefabricated zirconia abutments (ZR), though it was associated with increased probing depths.
| PICO | Description |
|---|---|
| Population | Adults undergoing posterior tooth extraction with immediate implant placement using static computer-assisted implant surgery (sCAIS). |
| Intervention | Chairside-fabricated composite Sealing Socket Abutments (CS). |
| Comparison | Prefabricated zirconia Sealing Socket Abutments (ZR). |
| Outcome | Both groups exhibited stable Supra-Platform Tissue Height over 3 months. THT decreased significantly in both groups (CS: −1.00 mm, ZR: −1.17 mm), with less horizontal shrinkage in the CS group. Probing pocket depth increased significantly in the CS group and decreased in the ZR group. Bleeding on probing improved in both groups, more notably in CS. |
