# A comparative analysis of peri-implant sulcular microflora in delayed versus immediately placed dental implants

## TL;DR

This study compares the bacterial communities in dental implants placed immediately after tooth extraction versus those placed later, finding differences in early microbial colonization.

## Contribution

The study provides new insights into how implant timing affects early microbial colonization and potential dysbiosis.

## Key findings

- Immediate implants showed higher commensal bacteria at 3 months.
- Delayed implants had increased pathogenic bacteria like Porphyromonas gingivalis at 6 months.
- Microbial differences between groups diminished by 12 months.

## Abstract

The timing of dental implant placement may influence early microbial colonization and long-term peri-implant health. This prospective
cohort study compared sulcular microflora in immediate (n=30) versus delayed (n=30) single-tooth implants over 12 months using 16S rRNA
sequencing. Immediate implants showed higher levels of commensal genera at 3 months, whereas delayed implants exhibited increased
colonization by Porphyromonas gingivalis and Tannerella forsythia at 6 months (p<0.05). By 12 months, microbial differences
diminished, with convergence of pathogenic species between groups. Delayed placement appears more prone to early dysbiosis, underscoring
the need for rigorous plaque control and monitoring.
