Abstract

Amalgam is very controversial as dental filling material because of its high mercury content. Plastic-based composites cannot be used without restrictions because of their low hardness and the polymerisation shrinkage. The material combination of an inorganic matrix which expands little and in which firmly bound particles of suitable metals are embedded displays by contrast a greater hardness and stability in the mouth than plastics or amalgams.

Description

Seit geraumer Zeit wird in der wissenschaftlichen Zahnheil­ kunde nach Werkstoffen gesucht, die in plastischem Zustand in vorpräparierte Hohlräume defekter Zähne eingefüllt und zur anatomischen Kronenform modelliert werden, um anschließend auszuhärten.Has been in scientific dentistry for quite some time customer was looking for materials that are in plastic condition in Prepared cavities of defective teeth are filled in anatomical crown shape can be modeled to subsequently harden.

Ein bisher bevorzugter Werkstoff dieser Art ist das Amalgam, dessen Biokompatibilität infolge des hohen Quecksilberantei­ les neuerdings wieder stark umstritten ist. Kunststoffe und Komposites auf der Basis einer Kunststoffmatrix mit Quarz, Glas und SiO2 als Mikrofüller kontrahieren während der Poly­ merisation, so daß ein Randspalt entsteht, der zur Karies führen muß. Gleichzeitig sind Kunststoffe nicht uneinge­ schränkt mundbeständig infolge der Wasserquellung und der mechanischen Abnützung.A previously preferred material of this type is amalgam, the biocompatibility of which has recently become highly controversial due to the high mercury content. Plastics and composites based on a plastic matrix with quartz, glass and SiO 2 as microfillers contract during the polymerization, so that an edge gap is created which must lead to caries. At the same time, plastics are not unrestrictedly mouth-resistant due to water swelling and mechanical wear.

Um diese gravierenden Nachteile dieser bisher bevorzugten Füllungswerkstoffe zu umgehen, wird in der vorliegenden Anmeldung eine erfindungsgemäße, neu­ artige Werkstoffkombination vorgestellt, die aus einer anor­ ganischen kristallisationsfähigen Matrix besteht, in die Partikel aus geeigneten mundbeständigen Metallen oder deren Legierungen, bevorzugt aus silberhaltigen Palladium- Legierungen als Mikro- oder Makrofüller, eingelagert sind. Im Vergleich zu den bisher gebräuchlichen Kunststoff-Kompo­ sites ergibt sich der wesentliche Vorteil dadurch, daß die Metallpartikel eine höhere kaufunktionelle Duktilität besitzen als Glaspartikel, während umgekehrt die anorganische Matrix eine größere Härte und signifikant bessere Mundbestän­ digkeit aufweist als die bisherige Kunststoffmatrix. Ein weiterer, wesentlicher Vorteil der erfindungsgemäßen Werk­ stoffkombination aber ist die geringe Expansion der anorga­ nischen Matrix während ihrer Kristallisationsphase wodurch - abermals entgegengesetzt der bisherigen Kunststoff-Komposites - eine Randspaltdichte resultiert.To these serious disadvantages to circumvent these previously preferred filling materials in the present application, a new one like material combination presented that from an anor ganic crystallizable matrix exists in which Particles of suitable mouth-resistant metals or their Alloys, preferably made of silver-containing palladium Alloys as micro or macro filler are stored. Compared to the previously used plastic compo The main advantage of sites is that the Metal particles have a higher functional ductility possess as glass particles, while conversely the inorganic  Matrix a greater hardness and significantly better mouth stocks than the previous plastic matrix. A Another essential advantage of the plant according to the invention The combination of fabrics, however, is the low expansion of anorga nical matrix during its crystallization phase whereby - again contrary to the previous plastic composites - An edge gap density results.
