Zusammenfassung
Heutzutage stehen modernste Techniken zur Verfügung, durch die mithilfe einer digitalen präoperativen Planung patientenspezifische Implantate (PSI) hergestellt werden können. Vorrangig ist hier das selektive Laserschmelzverfahren auf Titanpulverbasis zu nennen, das sowohl zur Herstellung patientenspezifischer Implantate beliebiger Geometrie und innerer Struktur für Orbita- und Mittelgesichtsrekonstruktionen als auch für jede andere anatomische Region geeignet ist. Alternativ können virtuelle Planungen auch durch die CNC-Frästechnik (CNC: computerized numerical control), Spritz- oder Formentechniken in Implantate umgesetzt werden. Diese Innovationen führen zur Herstellung einer perfekt formstabilen patientenspezifischen Implantatgeometrie. Darüber hinaus kann das Einsetzen und die intraoperative Positionierung dieser Implantate mithilfe dieser Technik gesteuert werden, durch die der gesamte Kreislauf der präoperativen Defektanalyse, patientenspezifischen Implantatherstellung und Insertion von Implantaten qualitätsgesichert werden kann.
Abstract
Highly modern techniques are available for computer-supported preoperative digital planning of the direct fabrication of patient-specific implants (PSI). The laser fusion procedure is suitable for producing patient-specific implants of any geometry and internal structure for orbital and midface reconstructions, but also for any other anatomical region, all based on titanium powder. These digital plans can control CNC milling (CNC: computerized numerical control) cutters or lead to implants produced by spraying or moulding techniques. This innovation leads to the production of perfectly formed and stable patient-specific orbital implants of the required geometry. The insertion and intraoperative positioning of these implants can be controlled using this technique to ensure the quality of the entire process: preoperative defect analysis, patient-specific production of implants, and insertion of implants.
