Abstract
Description
Die vorliegende Erfindung betrifft das zahnfarbene Verblenden von Metallkonstruktionen und ein hierfür geeignetes Dentalmaterial, insbesondere prothetisches Material.The The present invention relates to the tooth-colored veneering of metal structures and one for this suitable dental material, in particular prosthetic material.
Gerüste aus Edelmetalllegierungen oder Sonderlegierungen, wie z. B. CoCr werden bei der Verarbeitung zu Kronen oder Brücken mit Kompositen oder Keramiken zahnfarben verblendet. Auf das metallische Gerüst wird zunächst eine Haftvermittlerschicht aufgebracht, welche einen chemischen Verbund zwischen der Metalloberfläche und den nachfolgenden (Meth-)Acrylat basierten Schichten herstellt. Auf den Haftvermittler wird eine Schicht eines relativ transparenten, fließfähigen Materials aufgebracht, welches auch in die Toträume in den Hinterschneidungen der Retentionsperlen einfließen, diese auffüllen und schon leicht opak eingestellt sein kann (Pre-Opaker). Dabei muss sichergestellt sein, dass das Material dort ausreichend aushärtet. Auf diese fließfähige Schicht werden anschließend eine oder mehrere Schichten Opaker aufgebracht, um das Metall farblich zu kaschieren. Dabei wird der Opaker in Form einer Creme aufgetragen. Den Abschluss des Schichtaufbaus bildet das eigentliche Verblendkomposit.Scaffolding off Noble metal alloys or special alloys, such as. B. CoCr when processing into crowns or bridges with composites or ceramics tooth colors blinded. On the metallic framework is first a primer layer applied, which is a chemical bond between the metal surface and the subsequent (meth) acrylate based layers manufactures. On the primer is a layer of a relatively transparent, flowable material applied, which also in the dead spaces in the undercuts incorporate the retention beads, fill these up and already slightly opaque can be set (Pre-Opaker). there It must be ensured that the material hardens sufficiently there. On this flowable layer will be afterwards One or more layers of opaque applied to the metal in color to conceal. The opaque is applied in the form of a cream. The completion of the layer structure forms the actual veneering composite.
Die Aufgabe der vorliegenden Erfindung besteht darin, den Verbund fester auszuführen, insbesondere die Haftfestigkeit zu erhöhen und Hinterschneidungen, die von dem cremigen Opaker schlecht bedeckt werden, in hoher Qualität auszuführen. Vorzugsweise soll noch die Anzahl der aufgetragenen Schichten reduziert werden.The The object of the present invention is to make the composite stronger perform, in particular to increase the adhesion and undercuts, which are badly covered by the creamy opaque to perform in high quality. Preferably should still be reduced, the number of layers applied.
Erfindungsgemäß werden Pre-Opaker mit einer Scherviskosität unter 10 Pa·s, insbesondere unter 1 Pa·s und vorzugsweise unter 0,1 Pa·s bereitgestellt. Damit sind die erfindungsgemäßen Pre-Opaker Suspensionen, die sich trotz Hinterschneidungen zu einer Schicht mit gleichmäßiger Schichtdicke ausbilden und in diesem Sinn komplizierte Schichtmuster bei gleicher Schichtdicke ausbilden.According to the invention Pre-opaquer with a shear viscosity below 10 Pa · s, in particular below 1 Pa · s and preferably below 0.1 Pa · s provided. Thus, the pre-opaque suspensions according to the invention are despite being undercuts to a layer with uniform layer thickness train and in this sense complicated layer patterns at the same Form layer thickness.
Insbesondere weisen die erfindungsgemäßen Suspensionen einen Haftvermittler auf und sind deshalb auch als Haftvermittler anwendbar, wobei dadurch ein Schichtauftrag eingespart werden kann. Bei einem Haftvermittler wird die transparente, fließfähige Schicht leicht opak eingestellt, insbesondere mit 2 bis 7 Gew.-% Pigmenten, insbesondere mit 3 bis 5 Gew.-%, um bei noch ausreichender Aushärtetiefe schon einen leichten Abdeckungseffekt zu erreichen und die Anzahl der aufgetragenen opaken Schichten zu reduzieren.Especially have the suspensions according to the invention a bonding agent and are therefore also as a bonding agent applicable, whereby a layer order can be saved. at a primer, the transparent, flowable layer is slightly opaque, in particular with 2 to 7% by weight of pigments, in particular with 3 to 5 wt .-%, to even with sufficient curing depth already a slight To achieve coverage effect and the number of applied opaque layers to reduce.
In erfindungsgemäßer Weiterbildung werden die aktiven Substanzen des Haftvermittlers in die leicht opak eingestellte, fließfähige Pre-Opaker-Schicht eingebracht.In Inventive training the active substances of the coupling agent become easy opaque, flowable pre-opaque layer brought in.
Hierdurch wird ein weiterer Schichtauftrag eingespart.hereby a further layer order is saved.
Vorzugsweise weist die erfindungsgemäße Suspension 40 bis 60 Gew.-% Lösungsmittel wie z. B. Aceton und geringe Mengen Wasser auf; 30 bis 50 Gew.-% Monomere, insbesondere 20 bis 40 Gew.-% einfach funktionelle Monomere und bis 20 Gew.-% mehrfach funktionelle Monomere sowie gegebenenfalls 0,5 bis 2 Gew.-% Haftmonomere; 2 bis 7 Gew.-%, insbesondere 3 bis 5 Gew.-% Pigmente, 0,1 bis 2 Gew.-% Photoinitiatoren und gegebenenfalls Glasperlen als Füllmaterial.Preferably has the suspension according to the invention 40 to 60 wt .-% solvent such as Acetone and small amounts of water; From 30 to 50% by weight Monomers, in particular 20 to 40 wt .-% of simply functional monomers and up to 20 wt .-% polyfunctional monomers and optionally From 0.5% to 2% by weight of adhesive monomers; 2 to 7 wt .-%, in particular 3 to 5 wt .-% pigments, 0.1 to 2 wt .-% of photoinitiators and optionally glass beads as filler.
Weiterhin empfiehlt sich die Zugabe folgender Additive:
- • bis zu 5 Gew.-% PMMA;
- • bis zu 5 % Rheologie-Modifikatoren, beispielsweise pyrogene Kieselsäure; und
- • bis zu 0,2 Gew.-% Stabilisatoren, beispielsweise Butylhydroxytoluol (BHT)
- Up to 5% by weight PMMA;
- • up to 5% rheology modifiers, such as fumed silica; and
- Up to 0.2% by weight of stabilizers, for example butylhydroxytoluene (BHT)
Die erfindungsgemäße Suspension spreizt sehr schnell und hat gegenüber den bekannten Cremes eine deutlich verbesserte Benetzbarkeit der Metalloberfläche. Deshalb werden auch Toträume in Hinterschneidungen genauso gut benetzt wie gerade Flächen. Die erfindungsgemäße Suspension fließt gleichmäßig in die Hinterschneidungen und füllt diese in gleicher Qualität auf. Auch härtet das Material in den Hinterschneidungen in gleicher Qualität aus. Nach dem Auftrag von zwei weiteren Opakerschichten kann bereits das eigentliche Verblendkomposit aufgetragen werden. Dabei wurde ein Schichtauftrag eingespart. Der chemische Verbund zur Metalloberfläche erfolgt über den Haftvermittler, beispielsweise über Phosphatester bzw. Schwefelgruppen. Die Anbindung an den Opaker und das Komposit erfolgt über (Meth-)Acrylatgruppen. Die Aushärtung erfolgt vorzugsweise mittels eines durch sichtbares Licht initiierten Härtemechanismus.The suspension according to the invention spreads very fast and has compared to the known creams one significantly improved wettability of the metal surface. Therefore are also dead spaces wetted in undercuts just as well as surfaces. The suspension according to the invention flows evenly into the Undercuts and fills these in the same quality on. Also hardens the material in the undercuts in the same quality. To the commissioning of two more layers of opaque can already do the actual Veneering composite can be applied. This saved a shift order. The chemical bond to the metal surface via the Adhesive agents, for example about Phosphate ester or sulfur groups. The connection to the opaque and the composite is over (Meth) acrylate groups. The curing is preferably carried out by means of a visible light initiated Curing mechanism.
Das erfindungsgemäße Verfahren besticht durch seine Einfachheit, da ohne zusätzliche Geräte Verarbeitungsschritte eingespart werden und die Festigkeit des Dentalerzeugnisses erheblich verbessert wird.The inventive method captivates by its simplicity, since it saves processing steps without additional devices and the strength of the dental product is significantly improved becomes.
Im Folgenden wird die Erfindung mit Bezug auf die anliegenden Zeichnungen verdeutlicht.in the The invention will now be described with reference to the accompanying drawings clarified.
