title: Five-Year Volumetric Evaluation of Periodontally Compromised Sites Restored by Immediate Implant Restorations.
abstract: The aim of the present study was the retrospective evaluation of the distance of the labial hard and soft tissue margins from the implant shoulder in 24 periodontally compromised sites that were restored by immediate implant restorations. Volumetric analysis was performed 5 years postoperatively using cone beam computed tomography with limited field of view. In all cases, a labial radiopaque plate component was apparent 5 years postoperatively coronal to the implant shoulder (3.1 ± 0.6 mm), supporting the soft tissue margin, which was extending above this level (5.2 ± 1.1 mm). In 12 of the sites, preoperative evaluation showed that this plate was missing at the time of implant placement.
