Description
Oppfinnelsen vedrører et legeringspulver eller legeringspulver-blandlng til fremstilling av dentalamalgam, som ved siden av de vanlige legeringskomponenter inneholder sølv, 5-80 vekt-# titan samt eventuelt som ytterligere vanlige legeringskomponenter tinn, kobber, zink og vanlige tilsetninger som f.eks. palladium, gull, platina eller indium. The invention relates to an alloy powder or alloy powder mixture for the production of dental amalgam, which, in addition to the usual alloy components, contains silver, 5-80 wt-# titanium and possibly as further usual alloy components tin, copper, zinc and usual additives such as e.g. palladium, gold, platinum or indium.
Den ifølge oppfinnelsen utformede legering lar seg, etter triturering eller etter legging av amalgamfyllingen i kaviteten, ved kjemisk og/eller elektrokjemisk behandling innbefattende innvirkning av munnmiljø farge således at den metalliske karakter av fyllingens overflate endrer seg i retning av et lyst, ikke metallisk til tannsubstansens farge tilpassende utseende. The alloy designed according to the invention can be colored, after trituration or after placing the amalgam filling in the cavity, by chemical and/or electrochemical treatment, including the impact of the oral environment, so that the metallic character of the surface of the filling changes in the direction of a bright, non-metallic color to that of the tooth substance color adaptive appearance.
Dentalamalgamer har i lengere tid vist seg egnet i den konserverende behandling av tenner. Forsøk til å tilpasse det metalliske glinsende utseende av amalgamfyllinger til fargen av den omgivende tannsubstans, har hittil forblitt uten resultat. Oppfinnelsens oppgave var derfor å tilveie-bringe et legeringspulver eller en legeringspulverblanding til fremstilling av dentalamalgamer, hvor det metalliske utseende ved en spesiell behandling kan endres i retning mot det lyse, ikke metalliske utseende av tannsubstansen. Dental amalgams have long been shown to be suitable for the conservative treatment of teeth. Attempts to adapt the metallic shiny appearance of amalgam fillings to the color of the surrounding tooth substance have so far remained unsuccessful. The task of the invention was therefore to provide an alloy powder or an alloy powder mixture for the production of dental amalgams, where the metallic appearance can be changed by a special treatment towards the bright, non-metallic appearance of the tooth substance.
Dette formål løses ifølge oppfinnelsen med en legeringspulver-blanding av den innledningsvis nevnte type, som på grunn av nærvær av 5-80 vekt-# titan som 1 eger ingskomponent målrettet kan farges etter amalgameringen. Slike legeringspulvere resp. blandinger har hittil ikke vært kjent i tannbehandlingen. According to the invention, this purpose is solved with an alloy powder mixture of the type mentioned at the outset, which, due to the presence of 5-80% by weight of titanium as a special component, can be purposefully colored after the amalgamation. Such alloy powders or mixtures have so far not been known in dentistry.
Ifølge oppfinnelsen sammensatte legeringspulvere har fortrinnsvis følgende sammensetning: Alloy powders composed according to the invention preferably have the following composition:
20 - 95 vekt-* Ag20 - 95 weight-* Ag
5-80 vekt-* Ti5-80 weight-* Ti
0-15 vekt-* Cu0-15 wt-* Cu
0-45 vekt-* Sn0-45 weight-* Avg
0-10 vekt-* Zn0-10 wt-* Zn
Ved siden av disse legeringskomponenter kan det i dentalamalgamer forekomme vanlige tilsetninger, spesielt de innledningsvis nevnte. In addition to these alloy components, dental amalgams may contain common additives, especially those mentioned at the outset.
Den til triturering eller legging av amalgamfyllingen følgende kjemiske og/eller elekrokjemiske behandling består fortrinnsvis i innvirkning av egnede elektrolyttoppløsninger resp. suspensjoner med eller uten oksyderende tilsetninger resp. anlegg av en liten potensialdifferens i forhold til en inert elektrode. The chemical and/or electrochemical treatment following the trituration or placement of the amalgam filling preferably consists of the action of suitable electrolyte solutions or suspensions with or without oxidizing additives or installation of a small potential difference in relation to an inert electrode.
Oppfinnelsen skal forklares nærmere ved hjelp av følgende eksempler. The invention shall be explained in more detail by means of the following examples.
Eksempel 1Example 1
En legering av 57 vekt-* Ti, 40 vekt-* Ag, 2 vekt-* Zn og 1 vekt-* Cu smeltes i lysbueovnen under 99,98*-ig, ved hjelp av Ti-svamp fylt (gegettert) Ar, avspennes under benzol og males til en kornstørrelse < 80 pm under permanent avkjøling ved hjelp av flytende nitrogen. Oppvarmingen av malegodset til værelsestemperatur må foregå under luftutelukkelse. An alloy of 57 wt-* Ti, 40 wt-* Ag, 2 wt-* Zn and 1 wt-* Cu is melted in the arc furnace under 99.98*-ig, using Ti sponge filled (gegetated) Ar, destressed under benzene and ground to a grain size < 80 pm under permanent cooling using liquid nitrogen. The heating of the paint material to room temperature must take place under exclusion of air.
Det således dannede legeringspulver gir etter amalgameringen en tilstrekkelig plastisk masse, som umiddelbart etter fyllingens legging bestrykes med en vandig blanding av magnes iumf osf at og natriumsil ikat, pufret ved hjelp av ammoniumfosfat til en pH-verdi mellom 10 og 12, idet det opptrer en omfarging, som sammenlignet med vanlige amalgamer viser en fargeverdiforskyvning i retning mot tannmaterialet. The alloy powder thus formed gives, after amalgamation, a sufficiently plastic mass, which is coated immediately after the filling is laid with an aqueous mixture of magnesium phosphate and sodium silicate, buffered with the aid of ammonium phosphate to a pH value between 10 and 12, as a discoloration, which compared to ordinary amalgams shows a color value shift in the direction of the tooth material.
Eksempel 2Example 2
En legering, bestående av 70 vekt-* Ag og 30 vekt-* Ti smeltes som angitt i eksempell, avspennes og males, imidler-tid utsiktes til en kornstørrelse på < 60 pm. Etter amalgamer ingen omspyles pastaen ca. 3-5 minutter etter legging av fyllingen og tilstrekkelig herding med en 2m vandig oppløs-ning av natriumhydrogenfosfat, idet fyllingen skjaltes anodisk ovenforen Pt-katode med +1,0 til 1,8 V. I løpet av ca. 1-2 minutter oppnås en lysgjøring av amalgamfyllingen analogt eksempel 1. An alloy, consisting of 70 wt-* Ag and 30 wt-* Ti is melted as indicated in example 1, relaxed and ground, although a grain size of < 60 pm is expected. After no amalgams, the paste is rinsed approx. 3-5 minutes after placing the filling and sufficient curing with a 2m aqueous solution of sodium hydrogen phosphate, the filling being anodically scalded above the Pt cathode with +1.0 to 1.8 V. During approx. 1-2 minutes, a lightening of the amalgam filling is achieved analogously to example 1.
Eksempel 3Example 3
En legering, bestående av 52 vekt-* Ag, 38 vekt-* Ti og 10 vekt-* Sn, smeltes, avspennes og males som omtalt i eksempell og utsiktes til en kornstørrelse på < 60 pm. Etter amalgameringen og legging av fyllingen laes etter ca. 30 minutters herding det innvirke en vandig oppløsning av 5* natriumsili-kat, 2* hydrogenperoksyd og 1* natriumhydrogenfosfat inntil opptreden av en lysgjøring. An alloy, consisting of 52 wt-* Ag, 38 wt-* Ti and 10 wt-* Sn, is melted, annealed and ground as discussed in example 1 and is prospected to a grain size of < 60 pm. After the amalgamation and laying of the filling, it is left after approx. After 30 minutes of curing, apply an aqueous solution of 5* sodium silicate, 2* hydrogen peroxide and 1* sodium hydrogen phosphate until the appearance of lightening.
Eksempel 4Example 4
En legering, bestående av 65 vekt-* Ag og 35 vekt-* Ti, smeltes, avspennes og males som omtalt i eksempel 1, imidler-tid utsiktes til en kornstørrelse på < 33 pm. An alloy, consisting of 65 wt-* Ag and 35 wt-* Ti, is melted, annealed and ground as described in example 1, although a grain size of < 33 pm is expected.
Det således fremstilte legeringspulver blandes i forholdet 2:1 med en vanlig legering bestående av 70 vekt-* Ag, 27 vekt-* Sn og 3 vekt-* Cu med en kornstørrelse på < 33 pm. The alloy powder produced in this way is mixed in a ratio of 2:1 with a normal alloy consisting of 70 wt-* Ag, 27 wt-* Sn and 3 wt-* Cu with a grain size of < 33 pm.
Etter amalgamer ingen og legging av fyllingen laes det etter ca. 5 til 8 minutter innvirke en nytilberedt vandig oppløs-ning som inneholder 40 g natr iumsilikat, 25 g sinksulfat, 0,5* sitronsyre og 1* natriumperoksyd, inntil opptreden av lysgjøring- Etter ca. 5 minutters innvirkningstid var lysgjøringen noe mindre intensivt utpreget enn omtalt i eksemmplene 1 til 3. After no amalgams and placing the filling, it is laid after approx. For 5 to 8 minutes, apply a freshly prepared aqueous solution containing 40 g of sodium silicate, 25 g of zinc sulfate, 0.5* citric acid and 1* sodium peroxide, until lightening occurs - After approx. After a 5-minute exposure time, the lighting was somewhat less intensive than described in examples 1 to 3.
Eksempel 5Example 5
En legering av 75 vekt-* Ag og 25 vekt-* Ti smeltes under reneste argon og fordyset etter smelting til partikler An alloy of 75 wt-* Ag and 25 wt-* Ti is melted under pure argon and jetted after melting into particles
< 33 pm. Etter amalgamer ingen og legging av fyllingen foretas etter en herdingsvarighet på minst ca. 10 minutter en omfarging på elektrokjemisk måte (analogt eksempel 2) resp. på kjemisk måte (analogt eksempel 3). Herved fåes en lysgjøring av amalgamfyllingen analogt eksemplene 1 til 3. < 33 p.m. After no amalgams and placing the filling is done after a curing time of at least approx. 10 minutes a recoloring in an electrochemical way (similar to example 2) resp. in a chemical way (analogous to example 3). This results in a lightening of the amalgam filling analogous to examples 1 to 3.
