Difference Between Classes Of Implants And Their Surface Contamination

The aim of this study was to differentiate the surface of high-end and low-end implants, i.e. which chemical elements are present on them during cleaning of the implants. One group (10 implants) consisted of high-end implants that have been extensively studied in scientific and clinical research and have been available on the market for a long time. The second group (10 implants) included newer implants that are relatively recent to the market, with limited research data available and a lower price point compared to the first group. The analysis focused on the surface of the dental implants and was conducted using a Scanning Electron Microscope (SEM). The Electron Sample analysis can be performed using SE (Secondary Electron) and/or BSE (Backscattered Electron) detectors. With proper sample preparation, resolutions better than 5 nm can be achieved. Using scanning electron microscopy, a range of chemical elements was detected on the surfaces of implants across all study groups. The first group (low-end implants) showed a high presence of these elements. In contrast, the second group (high-end) of implants exhibited a notably different surface composition, containing only a minimal number of chemical elements. Titanium is the primary choice for implants due to its biocompatibility and durability, while the addition of elements such as calcium, phosphorus, zinc, magnesium, and silver can significantly enhance the process of osseointegration, increase stability, and reduce the risk of infections.
