Chairside vs Prefabricated Sealing Socket Abutments for Posterior Immediate Implants: A Randomized Clinical Trial
Abstract
OBJECTIVES
This randomized clinical trial aimed to compare changes in soft tissue height, probing depth, and buccal contour volume loss following immediate implant placement using either chairside composite or prefabricated zirconia Sealing Socket Abutments (SSAs) in the posterior region.
MATERIALS AND METHODS
47 patients requiring posterior tooth extraction and immediate implant placement were randomly assigned to one of two groups: the composite Sealing Socket Abutment (CS) group (n = 24), receiving chairside-fabricated abutments, or the zirconia Sealing Socket Abutment (ZR) group (n = 23), receiving prefabricated abutments. Implants were placed immediately after extraction, using static computer-assisted implant surgery (sCAIS). Supra-Platform Tissue Height (SPTH) and total horizontal tissues (THT) were assessed using cone-beam computed tomography (CBCT) over a 3-month healing period. Implant survival, probing pocket depths (PPD), bleeding on probing (BOP) and plaque index (PI) were recorded clinically, while volumetric analysis was performed using digital impressions.
RESULTS
SPTH remained stable from baseline to the 3-month follow-up, with a mean change of -0.17 mm in the CS group and -0.44 mm in the ZR group. These differences were not statistically significant (p > 0.05). THT exhibited significant horizontal shrinkage in both groups over the 3-month period. In the CS group, THT decreased by 1.00 mm, while the ZR group showed a reduction of 1.17 mm (p < 0.001). PPD…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 47 participants or records.
