# The Influence of Surface Damage on Miniplates: A Study of Bacterial Attachment Across Various Strains

## TL;DR

This study shows that damaged miniplates used in facial surgery attract more bacteria, increasing infection risks.

## Contribution

The study reveals how surface damage on miniplates affects bacterial attachment and infection risk in oral surgery.

## Key findings

- Miniplates with severe surface damage showed higher bacterial attachment than undamaged ones.
- Certain bacterial strains like Staphylococcus aureus adhered more strongly to damaged surfaces.
- Surface damage increases the risk of postoperative infections in orthognathic surgery.

## Abstract

Miniplates are frequently used in oral and maxillofacial surgery to address malocclusion issues. However, surface damage to miniplates is a significant concern that can affect surgical outcomes and patient quality of life. This study aims to evaluate the influence of miniplate surface damage on bacterial attachment, which may lead to postoperative infections.

Miniplates with varying degrees of surface damage were used in this study. The damaged surfaces were subjected to special treatments to simulate postoperative conditions. Various bacterial strains, including Staphylococcus aureus, Pseudomonas aeruginosa, and Streptococcus mutans, were tested. Each type of bacteria was cultured on different miniplates for specific durations, and bacterial attachment was subsequently measured and analyzed.

Surface damage to miniplates significantly influenced bacterial attachment. Miniplates with more severe surface damage exhibited higher levels of bacterial attachment compared to undamaged miniplates. Furthermore, the type of bacteria impacted attachment levels, with certain strains demonstrating higher adhesion than others.

Surface damage to miniplates increases the risk of postoperative infections due to enhanced bacterial attachment. Therefore, maintaining the integrity of miniplates during and after orthognathic surgery is crucial. Further research is necessary to develop prevention and management strategies for postoperative infections related to miniplate surface damage.
