Description
in CJ 10 15 20 25 30 35 CH 2 cering pà fler ställen i kronor än de kända retentionsele- menten kunnat. in CJ 10 15 20 25 30 35 CH 2 cering in more places in kronor than the known retention elements could.
Ett utföringsexempel pà uppfinningen beskrivs nu när- under fig 1 fig 2 fig 3 fig 4 fig 5 tentionssystemet enligt uppfinningen i en krona. mare hänvisning till bifogade är är är är och 6 visar olika monteringsmöjligheter för re- ritningar, där en perspektivvy av en matris, en längdsektionsvy av matrisen, en perspektivvy av en patris, en vy underifrån av patrisen och Det visade retentionssystemet innefattar en platt, làngsträckt patris P med stam 1 och dubbelfjädertungor 2 i stamförlängningen vid ena änden, och en matris M med ett vid ena änden öppet spår 3 anordnat att med tämligen snäv passning men glidbart mottaga patrisen. Härvid är patrisen helt infälld i matrisen. Spáret 3 är fasat liksom patri- sens längskantsytor. Matrisen är avsedd att ingjutas i metallen (guld) som skall bilda ytterkronan efter en sed- vanlig vaxmodell. Matrisen har också spàr 4 för ordentligt ingrepp med ytterkronan. Patrisen består av någon lämplig fjädrande hárdmetall.An exemplary embodiment of the invention is now described below in Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 5 The tension system according to the invention in a crown. more reference to the accompanying is is is is and 6 shows various mounting options for drawings, where a perspective view of a matrix, a longitudinal sectional view of the matrix, a perspective view of a matrix, a bottom view of the matrix and The retention system shown comprises a flat, elongated patris P with stem 1 and double spring tongues 2 in the stem extension at one end, and a matrix M with a groove 3 open at one end arranged to receive the patris with a rather tight fit but slidably. In this case, the patrix is completely embedded in the matrix. The groove 3 is bevelled as are the longitudinal edge surfaces of the patrician. The matrix is intended to be cast in the metal (gold) that will form the outer crown according to a usual wax model. The matrix also has groove 4 for proper engagement with the outer crown. The patris consists of some suitable resilient carbide.
Spàret 3 i matrisen leder till en urtagning 5, i vil- ken ett fràn storsidan utàtriktat utskott 6 pà patrisens ena dubbelfjädertunga 2 kan insnäppa. Den andra tungans utskott 6 är avsett att ingripa med ett i innerkronan upp- taget urtag, som kan upptagas med borr efter ett märke som denna andra tungas utskott lämnar efter sig, efter t ex infärgning av det, pà innerkronan. Utskotten 6 är här bil- dade genom ombockning av tungändarna. Patrisen har ett hål 7 för montering och demontering.The groove 3 in the matrix leads to a recess 5, in which a projection 6 extending from the large side on one of the double spring tongue 2 of the padris can snap. The projection 6 of the second tongue is intended to engage with a recess received in the inner crown, which can be picked up with a drill after a mark which the projection of this other tongue leaves behind, after, for example, staining it, on the inner crown. The projections 6 are formed here by bending the tongue ends. The partition has a hole 7 for assembly and disassembly.
I fig 5 och 6 visas retentionsystemet pá plats i en teleskopkrona med ytterkrona 8 och innerkrona 9. Den pre- parerade tanden, vid vilken innerkronan är fast cemente- rad, har hänvisningssiffran 10.Figures 5 and 6 show the retention system in place in a telescopic crown with outer crown 8 and inner crown 9. The prepared tooth, at which the inner crown is firmly cemented, has the reference numeral 10.
Närmare bestämt visas i fig 5 retentionssystemet vila pà en fräst hylla på innerkronan 9, med det ena fjädrande tungutskottet 6 i ingrepp med ett urtag ll i innerkronan 10 15 20 25 30 35 3 9, och visas i fig 6 retentionssystemet monterat utan hylla pà innerkronan, varvid patrisen kan tas av från kro- nans ocklusalyta. Den utstickande delen skall markera att matris- och patrislängden till en början kan vara onödigt làng och kan efter gjutning kapas för anpassning till krontoppen.More specifically, Fig. 5 shows the retention system resting on a milled shelf on the inner crown 9, with one resilient tongue projection 6 engaged with a recess 11 in the inner crown 10 15 20 25 30 35 3 9, and Fig. 6 shows the retention system mounted without a shelf on the inner crown , whereby the patris can be removed from the occlusal surface of the crown. The protruding part should mark that the length of the matrix and partition can at first be unnecessarily long and can be cut after casting to adapt to the crown top.
Det är underförstått att vid utskottet 6 släpper sitt grepp om sen kvarblir i matrisen. Urtagningen 5 och motsvarande avtagning av ytterkronan urtaget ll medan patri- utskott 6 är inga nödvändigheter för uppfinningens syften.It is understood that at committee 6 it releases its grip if it then remains in the matrix. The recess 5 and the corresponding removal of the outer crown recessed 11 while the patriotic projection 6 are not necessary for the purposes of the invention.
Patrisbyte eller patrisjustering, såsom utátbockning för bättre sàdant ingrepp, kan utföras genom att spetsen pà ett av tungan 2 som skall ingripa med innerkronan, spetsinstrument införes i hålet 7 och patrisen drages ut ur matrisen, varpà ny patris eller den justerade patrisen skjuts pà sin plats i matrisen. Retentionssystemet enligt uppfinningen har kunnat tillverkas med 1,2 mm totaltjock- lek, vilket skall jämföras med de konventionella fjädrande retentionssystemens totaltjocklek pà ca 2 mm.Particle change or particle adjustment, such as bending out for better such engagement, can be performed by inserting the tip of one of the tongue 2 to engage the inner crown, tip instrument into the hole 7 and pulling the particle out of the die, whereupon a new particle or the adjusted particle is pushed into place in the matrix. The retention system according to the invention has been manufactured with a total thickness of 1.2 mm, which is to be compared with the total thickness of the conventional resilient retention systems of about 2 mm.
Retentionssystemet enligt uppfinningen kan även an- vändas i hybridprotes, varvid det placeras pà en eller fler frästa pelare, dvs kan användas som rotförankring.The retention system according to the invention can also be used in hybrid prostheses, whereby it is placed on one or more milled pillars, ie can be used as root anchoring.
