Factors associated with prosthetic complications with individualized abutments: Real-world data


A key advantage of individualized implant abutments over stock abutments is their great restorative flexibility to allow optimal emergence profile to promote healthy soft tissue development, superior support of more complicated rehabilitations, and improved crown retention (1,2). In addition, many individualized abutments are made from zirconia or titanium, offering a quality solution with clinically demonstrated long-term survival (3,4).

The aim of this study was to assess prosthetic complications with individualized abutments fitted on TiUnite-surface implants and identify factors associated with higher complication rates

Key Results

  • Cumulative prosthetic survival was 98.1%. Of the 9 failures out of 463 abutments, 4 were recorded for full zirconia crowns, 3 for zirconia abutments, and 2 for ASC abutments.
  • The rate of biologic complications (at the supporting implant) was 2.8%
  • Indication short bridge, 2-stage surgery (submerged healing), narrow and regular platforms, early loading, and FCZ abutment type were associated with a lower risk of prosthetic failure (Cox PH analysis; HR>4 and p<0.05).
  • Jaw, implant/connection type and site type (healed versus extraction) showed no association or had an insufficient number of records.
  • Most patients (96.5%) and clinicians (98.3%) were satisfied with the restoration.
