Why it matters for dental

Implant-restoring dentists and specialists gain new quantitative data on how much supracrestal tissue height changes during healing-abutment seating in posterior sites, information that directly affects abutment selection, emergence-profile design, and long-term peri-implant tissue stability.

Key points

  • Retrospective analysis of intraoral scans from 37 posterior implants shows mean supracrestal tissue height increases of 0.6–0.9 mm between second-stage surgery and final impression.
  • Tissue height change is statistically greater in the mandible (mean +0.9 mm) than the maxilla (mean +0.6 mm), influencing decisions on final abutment length and cement margin placement.
  • Study uses intraoral scanning to quantify soft-tissue rebound, offering clinicians a non-radiographic method for tracking healing-abutment outcomes in daily practice.
  • Findings apply to both single-tooth and short-span posterior implant restorations; no significant correlation found between patient age or smoking status and tissue-height change.
