  1. PAT E NT K RAV
    1. Fremgangsmåde til frembringelse af en fysisk tandmodel, omfattende: at tilvejebringe et virtuelt tredimensionelt (3D) billede af en patients dentition eller en del deraf; og at udfærdige en fysisk model af kæberne baseret på information fra det virtuelle 3D-billede; hvor den fysiske model er en positiv model eller en negativ model, hvoraf en positiv model kan fremstilles, hvor modellen omfatter to elementer (100,102; 120,122), hvor en repræsenterer overkæben og den anden underkæben, og begge elementer fremstilles med markeringer eller et justeringsarrangement for at muliggøre korrekt okklusionsjustering af den positive models to elementer, hvor justeringsarrangementet indbefatter et monteringsapparat til montering af elementerne på en artikulator (104), hvor det virtuelle 3D-biIlede forud for udfærdigelsen af de to elementer (100, 102; 120, 122) virtuelt kombineres med artikulatoren (104) for at definere artikulatorindgrebsdele i elementerne; eller hvor justeringsarrangementet indbefatter et eller flere justeringsreferencekomponenter (124R, 126R) i hvert af modellens elementer, hvor komponenterne i de to elementer svarer til hinanden således, at hver komponent i et af elementerne kan justeres til at passe til den tilsvarende komponent i det andet af elementerne for at give korrekt justering af de to elementer, hvor den ene eller flere justeringsreferencekomponenter (124R, 126R) fremstilles virtuelt forud for udfærdigelsen af de to elementer (100,102; 120, 122).
  2. 2. Fremgangsmåde ifølge krav 1, hvor modellen er en gipsmodel.
  3. 3. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, hvor patientens dentition eller en del deraf omfatter mindst et område af tænderne, der indbefatter en tandstub, hvorpå en krone skal påsættes, eller et område, hvorpå en bro skal påsættes.
  4. 4. Fremgangsmåde ifølge krav 3, omfattende baseret på information fra det virtuelle 3D-billede at frembringe en 3D-model af en krone, der skal påsættes på tandstubben.
  5. 5. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, hvor modellen er til fabrikation af en krone, bro eller anden dental indretning, omfattende trinet at frembringe en 3D-datafil af patientens kæber og af det rumlige forhold mellem kæberne i okklusion for at tilvejebringe det virtuelle 3D-billede.
  6. 6. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, hvor modellen fremstilles med computerstøttet fremstillingsteknologi.
  7. 7. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 5, hvor en computerdrevet fræsemaskine fremstiller modellen af et råemne.
  8. 8. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 5, hvor modellen fremstilles med 3D-litografi.
  9. 9. Fremgangsmåde ifølge et hvilket som helst af kravene 6 til 8, der endvidere omfatter baseret på 3D-datafilen at frembringe digitale data, der repræsenterer den tredimensionelle struktur af en virtuel krone eller bro; og at anvende de digitale data til at konstruere en virtuel krone eller bro til påsætning på en tandstub.
  10. 10. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, hvor markeringerne er i form af fordybninger eller fremspring på elementernes flader.
  11. 11. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 9, hvor justeringsarrangement indbefatter et monteringsarrangement til montering af elementerne på en artikulator (104), og hvor artikulatorindgrebsdelene (106) omfatter referencehuller (108), der kan indføres og gå i indgreb med huller (110) i artikulatoren, hvilket indgreb er via stifter (114), hvor artikulatorindgrebsdelene med referencehullerne indledningsvis er defineret i det virtuelle 3D-billede.
  12. 12. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, omfattende at frembringe digital information til fabrikation af en fysisk tandmodel.
