Abstract
Description
Stand der Technik sind digitale Herstellungsverfahren von Zahnersatz bei denen zunächst das Arbeitsmodell und sein Gegenkiefer digital zusammengefügt werden, um die Kaufläche des späteren Zahnersatzes zu gestalten.State of the art are digital manufacturing methods of dentures in which first the working model and its opposing jaw are digitally assembled to make the occlusal surface of the future dentures.
Bei der Planung der Bewegungsabläufe der Kauzyklen wird aber ignoriert, dass die Kondylen des menschlichen Schädels völlig anders verhalten, als starre Artikulatoren bewegen können.When planning the movements of the chewing cycles, it is ignored that the condyles of the human skull behave completely differently than rigid articulators can move.
Es gibt alternativ die Möglichkeit – nach erfolgter Präparation – auf dann speziell angefertigten Trägerplatten, die auf die präparierten Stümpfe aufgesetzt werden – spezielle Wachse aufzutragen, die dann im Munde des Patienten dessen Kaubewegungen „aufzeichnen”.Alternatively, after the preparation has been completed, special waxes can be applied to specially prepared carrier plates which are placed on the prepared stumps, which then "record" the chewing movements in the patient's mouth.
Handwerklich werden diese Träger und Wachsregistrate später auf das zahntechnische Modell aufgesetzt und mit Modellmaterial gekontert. Wenn dann diese Teile präzise und rein vertikal zueinander geführt werden kann der Zahnersatz zunächst gegen das Zentrikregistrat konstruiert und anschließend gegen das Funktionsregistrat des Patienten eingeschliffen werden.In terms of craftsmanship, these carriers and wax registrations are later placed on the dental model and countered with model material. Then, when these parts are guided precisely and purely vertically to each other, the dentures are first constructed against the Zentrikregistrat and then ground against the Funktionsregistrat the patient.
Das, was so handwerklich erledigt wird, kann auch digital erfolgen. Hierzu benötigt man das „Ebenbild” des präparierten Stumpfes, mechanisch – als Modell – oder digital – z. B. als Scan der Mundsituation oder einer Abformung, das aufgelegte „Zentrikregistrat”, gegen welches die idealisierte Kaufläche konstruiert wird um anschließend gegen das Funktionsregistrat digital „eingeschliffen” zu werden. Beide Registrate können ebenfalls rein mechanisch oder digitalisiert verwendet werden.What is done in such a way can also be done digitally. For this you need the "image" of the prepared stump, mechanically - as a model - or digital - z. B. as a scan of the oral situation or an impression, the launched "Zentrikregistrat", against which the idealized occlusal surface is constructed to then be digitally "ground" against the function registry. Both registrates can also be used purely mechanically or digitized.
So kann Zahnersatz hergestellt werden, der – auch unter Berücksichtigung der Stärke des verwendeten Befestigungszementes und der individuellen Funktionen im Mund des Patienten – ohne weitere „Einschleifarbeiten” im Munde des Patienten eingesetzt werden kann.Thus, dentures can be made, which - even taking into account the strength of the cement used and the individual functions in the patient's mouth - can be used without further "grinding" in the mouth of the patient.
