Abstract

In a method of preparing a filling (7) with light-tempering filling material, the filling (7) is contoured with a light-permeable matrix (6), which is connected to a light-source (4) via a light-permeable adaptor (1), or with an adaptor (9) formed with a bowl-like surface (10) that works as a matrix and can allow light to permeate, so that the filling is contoured and illuminated by the same apparatus. An apparatus for contouring and illuminating of light-tempered fillings (7) consisting of a light-permeable adaptor (1) with a hole (2) that receives a light-source (4) and has a hole (3) that receives an arm (5) on a similar light-permeable matrix (6), so that the filling can be contoured and illuminated by the same apparatus, or that a light-permeable adaptor (9) has a bowl-like surface (10) formed as a matrix and a hole (2) that receives a light-source (4).<IMAGE>

Description

8305730-7 å 1Ü 15 20 25 3D 35 Huvudändamålet med föreliggande uppfinning är att förenkla handhavandet av ljushärdade fyllningsmaterial vid klass V- fyllningar, genom att låta ljusledare utgöra fäste för matris- systemet, så att endast en hand behövs för att belysa fyllningen och för att hålla matrissystemet på plats. Därigenom erhålles en god kontroll över arbetsfältet samtidigt som matrisen kan hållas stabilt på plats. The main object of the present invention is to simplify the handling of light-cured filling materials in class V fillings, by allowing light guides to form a bracket for the matrix system, so that only one hand is needed to illuminate the filling and for to keep the matrix system in place. Thereby a good control over the working field is obtained at the same time as the matrix can be kept stable in place.

På marknaden finns en typ av klass V-matriser av glasklar plast vilka är lämpliga att använda till kombination med en adapter enligt föreliggande uppfinning. (Vivadent, Schan/Lichtenstein).On the market there is a type of class V matrices of clear plastic which are suitable for use in combination with an adapter according to the present invention. (Vivadent, Schan / Lichtenstein).

Dessa matríser är avsedda att hållas med pincett.These matrices are intended to be held with tweezers.

Tack vare den synnerligen enkla konstruktionen är uppfinningen enkel och mycket billig att tillverka i olika ljusgenomsläppli- plastmateriel,sàsom plexiglas eller polycarbonat eller dylikt.Thanks to the extremely simple construction, the invention is simple and very cheap to manufacture in various light-transmitting plastic materials, such as plexiglass or polycarbonate or the like.

Uppfinningen kommer att beskrivas närmare genom utföringsexempel under hänvisning till medföljande figurer.The invention will be described in more detail by means of exemplary embodiments with reference to the accompanying figures.

Fig 1 visar en ljusgenomsläpplig adapter 1 till en ljusledare 4 _ avsedd att hålla fast en buccalmatris (klass V-matris) 6. É Adaptern 1 består av en cylindrisk, urborrad kropp av ljusgenom- släppligt material. Den cylidriska urborrningen 2 är avsedd att mottaga ljusledaren 4, vilken införas i urborrningen 2 och kvar- hâlles genom friktion, skruvning e dyl. Den likaså cylindriska urborrningen 3 är avsedd att mottaga en arm 5 från en buccalmatris 8 (Vivadent), vilken också kvarhàlles genom friktion e dyl.Fig. 1 shows a light-transmitting adapter 1 to a light guide 4 intended to hold a buccal matrix (class V matrix) 6. The adapter 1 consists of a cylindrical, drilled body of light-transmitting material. The cylindrical bore 2 is intended to receive the light guide 4, which is inserted into the bore 2 and is retained by friction, screwing and the like. The likewise cylindrical bore 3 is intended to receive an arm 5 from a buccal matrix 8 (Vivadent), which is also retained by friction and the like.

Fig 2 visar hur adaptern 1 fungerar vid konturering och poly- merisering av en fyllning 7 i en tand 8. Ljusledare 4 är införd i adapterns urborrnimg 2 och buccalmatrisens arm 5 är införd i adapterns urborrning 3. Genom att hålla i ljusledaren 4 kan buocalmatrisen 8 pressas mot fyllningsmaterialet 7 och tanden 8, samtidigt som fyllningen belyses. Fyllningen ges kontur och tillåts polymerisera med ett enhandsgrepp. 10 3 asosvso-7 De på marknaden förekommande buocalmatriserna B finns i ett flertal storlekar på den del som skall användas till att konturera fyllningar 7, men alla storlekarna har samma dimensioner på armen 5. En adapter enligt ovan kan därför användas till ett stort antal fyllníngstyper.Fig. 2 shows how the adapter 1 works when contouring and polymerizing a filling 7 in a tooth 8. Light guide 4 is inserted into the bore 2 of the adapter and the arm 5 of the buccal matrix is inserted into the bore 3 of the adapter. pressed against the filling material 7 and the tooth 8, at the same time as the filling is illuminated. The filling is contoured and allowed to polymerize with a one-handed grip. 10 3 asosvso-7 The buocal matrices B available on the market are available in several sizes for the part to be used to contour fillings 7, but all sizes have the same dimensions on the arm 5. An adapter as above can therefore be used for a large number of filling types. .

Naturligtvis kan även adaptern utformas enligt fig 3, som visar en ljusgenomsläpplíg adapter 9 med en urborr- ning 2 som skall mottaga en ljusledare enligt fig 1 och 2, men där en skàlformad yta 10 fungeras som matris, motsvarande buccalmatrisen 6 i Fig 1 och 2. ~< v» 41Of course, the adapter can also be designed according to Fig. 3, which shows a light-transmitting adapter 9 with a bore 2 which is to receive a light guide according to Figs. 1 and 2, but where a shell-shaped surface 10 functions as a matrix, corresponding to the buccal matrix 6 in Figs. . ~ <v »41
