Abstract
|
Post-mortem histology serves as the gold standard for analysing new bone formation around dental implants. However, histomorphometry is a<br />time-consuming and destructive technique, limiting the analysis to around five histological sections per implant. As a non-invasive and nonionising<br />method magnetic resonance imaging (MRI) provides great soft tissue contrast which allows the visualization and differentiation of<br />newly formed bone tissue at the beginning of the mineralization process, where an appropriate detection with X-ray based techniques is not yet<br />possible. Polyetheretherketone (PEEK) is a promising alternative biomaterial being used for implants since the late 1990s [1]. The advantages of<br />the material are the chemical inertness, wear resistance, a low elastic modulus close to that of bone preventing stress shielding and the<br />compatibility to medical imaging, because it does not give rise to the typical artefacts seen in MRI and CT from metallic implants.
