Abstract
Methods of recording a muco-dynamic or immediate functional impression of the dental arches of a patient onto the base or peripheral borders of a prosthetic denture, or rebasing a patient's prosthetic denture, utilizing a non-ionic, non-hydrophilic, impression-forming composition comprising polyvinyl acetate, aliphatic ketones, aliphatic esters, aliphatic alcohols or aliphatic ethers, non-toxic, non-aromatic, plasticizing oils and non-toxic and non-extractable organic pigments.
Claims8
A method of recording a mucodynamic impression of the dental arches of a patient or of the peripheral areas of said arches onto the base or peripheral borders of a prosthetic denture utilizing a non-ionic, non-hydrophilic impression-forming composition comprising:
- ______________________________________ Polyvinyl acetate (PVAc) 50-85% by weight C.sub.3 to C.sub.6 aliphatic 2-25% by weight ketones C.sub.3 to C.sub.8 aliphatic 1-25% by weight esters C.sub.2 to C.sub.10 aliphatic alcohols 1-25% by weight or aliphatic ethers Non-toxic, non-aromatic, 0.5-10% by weight plasticizing oils selected from the group consisting of dioctyl adipate, glycerol triacetate and polyglycols Non-toxic and non-extract- 0-2% by weight, able black, yellow, red or white organic pigments ______________________________________
- and is free of any gel-forming components, peroxide-based catalysts, aromatic amine-based inhibitors, aromatic plasticizing oils or compounds and incompatible plasticizers, said method including the steps of:
- (a) heating said composition to about 50.degree. C. and spreading the heated composition on the base or peripheral borders of the denture;
- (b) inserting the denture into the patient's mouth and allowing it to remain in the mouth for about 3-4 days;
- and
- (c) removing the denture from the patient's mouth.
A method of recording an immediate functional impression of the dental arches of a patient onto the base of a prosthetic denture utilizing a non-ionic, non-hydrophilic impression-forming composition comprising:
- ______________________________________ Polyvinyl acetate (PVAc) 50-85% by weight C.sub.3 to C.sub.6 aliphatic ketones 2-25% by weight C.sub.3 to C.sub.8 aliphatic esters 1-25% by weight C.sub.2 to C.sub.10 aliphatic alcohols 1-25% by weight or aliphatic ethers Non-toxic, non-aromatic, 0.5-10% by weight plasticizing oils selected from the group consisting of dioctyl adipate, glycerol triacetate and polyglycols Non-toxic and non-extract- 0-2% by weight, able black, yellow, red or white organic pigments ______________________________________
- and is free of any gel-forming components, peroxide-based catalysts, aromatic amine-based inhibitors, aromatic plasticizing oils or compounds and incompatible plasticizers, said method including the steps of:
- (a) heating said composition to about 50.degree. C. and spreading the heated composition on the base or peripheral borders of the denture;
- (b) inserting the denture into the patient's mouth and allowing it to remain in the mouth for about 10-20 minutes;
- (c) rinsing the mouth with water;
- (d) removing the denture from the patient's mouth.
A method of rebasing a patient's prosthetic denture on a temporary, semipermanent or permanent basis utilizing a nonionic, non-hydrophilic impression-forming composition comprising:
- ______________________________________ Polyvinyl acetate (PVAc) 50-85% by weight C.sub.3 to C.sub.6 aliphatic ketones 2-25% by weight C.sub.3 to C.sub.8 aliphatic esters 1-25% by weight C.sub.2 to C.sub.10 aliphatic alcohols 1-25% by weight or aliphatic ethers Non-toxic, non-aromatic, 0.5-10% by weight plasticizing oils selected from the group consisting of dioctyl adipate, glycerol triacetate and polyglycols Non-toxic and non-extract- 0-2% by weight, able black, yellow, red or white organic pigments ______________________________________
- and is free of any gel-forming components, peroxide-based catalysts, aromatic amine-based inhibitors, aromatic plasticizing oils or compounds and incompatible plasticizers, said method including the steps of:
- (a) heating said composition to about 50.degree. C.
- (b) applying said heated composition to the areas of the denture requiring rebasing;
- and
- (c) inserting the denture into the patient's mouth.
