Three-dimensional analysis of maxillary denture displacement during reline impression procedure. 1985

N S Javid, and C G Michael, and H A Mohammed, and F A Colaizzi

The contourmeter was used to determine quantitatively the denture displacements caused by various impression materials and techniques during the relining of a maxillary denture. This study indicated the following conclusions. Tissue-conditioning material used with closed-mouth impression technique or light-bodied polysulfide used with either open- or closed-mouth technique caused the least denture displacement in the three dimensions when compared with regular-bodied polysulfide or zinc oxide and eugenol impression materials. Comparing the same impression materials used with either open- or closed-mouth technique showed no significant difference in maxillary denture displacements. A relined complete denture should be remounted on the articulator and the occlusion refined to eliminate occlusal mismatches resulting from three-dimensional denture displacements during relining.

UI	MeSH Term	Description	Entries
D003760	Dental Impression Materials	Substances used to create an impression, or negative reproduction, of the teeth and dental arches. These materials include dental plasters and cements, metallic oxide pastes, silicone base materials, or elastomeric materials.

D003761	Dental Impression Technique	Procedure of producing an imprint or negative likeness of the teeth and/or edentulous areas. Impressions are made in plastic material which becomes hardened or set while in contact with the tissue. They are later filled with plaster of Paris or artificial stone to produce a facsimile of the oral structures present. Impressions may be made of a full complement of teeth, of areas where some teeth have been removed, or in a mouth from which all teeth have been extracted.

D003767	Dental Occlusion, Balanced	Dental occlusion in which the occlusal contact of the teeth on the working side of the jaw is accompanied by the harmonious contact of the teeth on the opposite (balancing) side.

D003822	Denture Liners	Material applied to the tissue side of a denture to provide a soft lining to the parts of a denture coming in contact with soft tissue. It cushions contact of the denture with the tissues.	Cushion Liners,Cushion Liner,Denture Liner,Liner, Cushion,Liner, Denture,Liners, Cushion,Liners, Denture
D003823	Denture Rebasing	The process of refitting a denture by replacing the denture base material without changing the occlusal relations of the teeth. Rebasing may include adding to the denture base to compensate for resorptive changes to subjacent structures.

D003827	Denture, Complete, Upper	A complete denture replacing all the natural maxillary teeth and associated maxillary structures. It is completely supported by the oral tissue and underlying maxillary bone.
