Description
Stand der TechnikState of the art
Die Erfindung betrifft einen Röntgen-Messkörper gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to an X-ray measuring body according to the preamble of claim 1
Die implantologische Röntgendiagnostik wird im Regelfall mit Hilfe von Panoramaschichtaufnahmen durchgeführt. Bei der Herstellung von Panoramaschichtaufnahmen kommt es jedoch zu positionsbedingten Bildverzerrungen (aufgrund fehlerhafter Einstellungen) sowie zu gerätetypischen Vergrößerungen des Röntgenbildes, wobei Vergrößerungen gegenüber der tatsächlichen klinischen Situation um einen Faktor von 1:1,2 bis 1:1,7 auftreten können. Gemäß dem aktuellen Stand der Technik kann man davon ausgehen, dass eine Panoramaschichtaufnahme in der Horizontalen um etwa 30% bis 70% und in der Vertikalen etwa 20% bis 30% größer ausfällt als die tatsächliche klinische Situation. Dies hat zur Folge, dass die Knochenhöhe an der Implantationsstelle nur relativ ungenau bestimmt werden kann.The implantological X-ray diagnostics usually carried out with the help of panoramic shots. at However, the production of panoramic shots, it comes to Positional image distortions (due to incorrect settings) as well as device-typical enlargements the X-ray image, with enlargements over the actual Clinical situation by a factor of 1: 1.2 to 1: 1.7 occur can. According to the current State of the art, it can be assumed that a panoramic panoramic in the horizontal by about 30% to 70% and in the vertical about 20% to 30% larger than the actual clinical situation. This has the consequence that the bone height at the Implantation site can only be determined relatively inaccurate.
Um diese Nachteile auszugleichen, wurden Bissschablonen mit fixierten Röntgen-Referenzkugeln, die einen definierten Durchmesser aufweisen, entwickelt. Diese Metallkugeln sind im Röntgenbild als Verschattung erkennbar. Da der Durchmesser der Metallkugeln bekannt ist, kann mit Hilfe des einfachen Dreisatzes die tatsächliche Knochenstärke ermittelt werden. Trotz der erheblichen Verbesserungen, die solche Röntgen-Referenzkugeln gebracht haben, ist es weiterhin erforderlich, den Durchmesser der Röntgen-Referenzkugel auf dem Röntgenbild mit Hilfe eines Lineals zu messen und die Knochenstärke zu berechnen. Dies ist relativ aufwendig. Darüber hinaus erlaubt es eine solche Röntgen-Referenzkugel nicht, z. B. die axiale Anordnung des zukünftigen Implantates zu bestimmen.Around To compensate for these disadvantages, bite templates were fixed with X-ray reference spheres, the have a defined diameter developed. These metal balls are in the x-ray picture as Shading recognizable. As the diameter of the metal balls known is, with the help of the simple rule of three the actual bone strength be determined. Despite the significant improvements that such X-ray reference spheres have brought, it is still required, the diameter of the X-ray reference sphere on the x-ray with To measure the help of a ruler and to calculate the bone strength. This is relatively expensive. About that It also allows such an X-ray reference sphere not, z. B. to determine the axial arrangement of the future implant.
Offenbarung der ErfindungDisclosure of the invention
Es ist somit eine Aufgabe der vorliegenden Erfindung, einen Röntgen-Messkörper zu schaffen, mit dem sich die Knochenstärke genau und einfach bestimmen, sowie die spätere Bohrrichtung genauer anordnen lässt.It Thus, it is an object of the present invention to provide an X-ray measuring body create a precise and easy way to determine bone strength, as well as the later To arrange drilling direction more accurately.
Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Patentanspruch 1 angegebenen Merkmale. Weitere Ausgestaltungen der Erfindung sind Gegenstand von Unteransprüchen.Is solved this task according to the invention by the features specified in claim 1. Further embodiments The invention are the subject of subclaims.
Ein wesentlicher Aspekt der Erfindung besteht darin, einen Röntgen-Messkörper zu schaffen, der eine lang gestreckte Form hat und eine Markierung aufweist, die auf einem Röntgenbild sichtbar ist. Die Markierung ist dabei so ausgeführt, dass sie im Röntgenbild erkennbar ist und als Maßstab für die Bestimmung der Knochenhöhe herangezogen werden kann. Hierzu muss der Maßstab nur auf den Knochen (im Röntgenbild) durch Translation übertragen und abgelesen werden. Der virtuelle Implantatstollen wird bidimensional auf dem Knochen abgebildet.One An essential aspect of the invention is to an X-ray measuring body create, which has a long stretched shape and a marker that is on an x-ray is visible. The marking is designed so that they are in the X-ray image is recognizable and as a yardstick for the determination the bone height can be used. For this purpose, the scale only on the bone (in X-ray image) transmitted by translation and be read. The virtual implant tunnel becomes bi-dimensional pictured on the bone.
Wenn der Röntgen-Messkörper eine lang gestreckte, stabförmige Form aufweist, wird außerdem durch den Messkörper die spätere Bohrrichtung angezeigt. Die Bohrrichtung kann schließlich auf ein Mittel zum Führen des Bohrers übertragen werden. Bei Bedarf kann die Bohrrichtung noch korrigiert werden.If the X-ray measuring body a elongated, rod-shaped Is also characterized by the measuring body the later one Drilling direction displayed. The drilling direction can finally open a means of guiding of the drill become. If necessary, the drilling direction can still be corrected.
Die Markierung hat vorzugsweise die Form einer Skala, die im Röntgenbild sichtbar ist. Anhand dieser Skala kann später insbesondere die Knochenhöhe sehr genau und einfach abgelesen werden.The Marker preferably has the shape of a scale in the X-ray image is visible. On the basis of this scale, especially the bone height can be very much later be read accurately and easily.
Gemäß einer bevorzugten Ausführungsform der Erfindung umfasst die Markierung eine oder mehrere Ausnehmungen und/oder Vorsprünge. Die Ausnehmungen sind vorzugsweise in Form von Rillen gebildet. Die Rillen verlaufen vorzugsweise in Umfangsrichtung und sind parallel zueinander angeordnet.According to one preferred embodiment of The invention comprises the marking one or more recesses and / or protrusions. The recesses are preferably formed in the form of grooves. The grooves preferably extend in the circumferential direction and are parallel arranged to each other.
Der Messkörper ist vorzugsweise zylinderförmig gebildet und hat vorzugsweise einen runden Querschnitt.Of the measuring body is preferably cylindrical formed and preferably has a round cross-section.
Bei der Anfertigung einer Röntgenaufnahme wird der Messkörper in eine vorgegebene Öffnung in der Schablone gesteckt und vorzugsweise mit seinem dem Kiefer zugewandten, messerartigen Ende durch die Mukosa hindurch bis zum Knochen gedrückt.at making an X-ray the measuring body in a given opening stuck in the template and preferably with his jaw facing, knife - like end through the mucosa through to Bone pressed.
Am anderen Ende des Messkörpers sind vorzugsweise Mittel vorgesehen, die als Manipulations- und Kompressionshilfe während der OP dienen. Diese Mittel können z. B. eine Stellschraube umfassen, die in Axialrichtung des Messkörpers angeordnet ist und in ein Innengewinde des Messkörpers geschraubt werden kann. Diese Stellschraube wird vorzugsweise so eingestellt, dass der Messkörper von einem Zahn des anderen Kiefers gegen den Knochen gedrückt wird.At the other end of the measuring body are preferably provided means that as manipulation and Compression aid during serve the surgery. These funds can z. B. comprise a set screw, which is arranged in the axial direction of the measuring body is and can be screwed into an internal thread of the measuring body. This adjusting screw is preferably adjusted so that the measuring body of a Tooth of the other jaw is pressed against the bone.
Der Messkörper kann weiterhin Mittel zum Fixieren des Messkörpers an der Schablone aufweisen. Zu diesem Zweck kann beispielsweise eine Schraube vorgesehen sein, die in Lateralrichtung am Messkörper angeordnet ist und in ein zweites Innengesinde des Messköpers geschraubt werden kann.Of the measuring body may further comprise means for fixing the measuring body to the template. For example, a screw may be provided for this purpose, in the lateral direction on the measuring body is arranged and screwed into a second Innengesinde the Meßköpers can be.
