Factors = ridge height/conformation; base adaptation; occlusal harmony; neuromuscular control.
Complete Denture […] = resistance to vertical movement of denture base toward ridge (while emplacing)
Initial support from bone and mucosa when bilateral simultaneous contact of opposing posterior teeth.
Long-term support = load tissue areas most resistant to** […].**
Complete Denture Support = resistance to vertical movement of denture base toward ridge (while emplacing)
Initial support from bone and mucosa when bilateral simultaneous contact of opposing posterior teeth.
Long-term support = load tissue areas most resistant to resorption.
Complete Denture **[…] **= resistance to displacement of denture base away from ridge.
Include principles of adhesion and cohesion.
**[…] **= attraction b/t unlike molecules.
**[…] **= force b/t molecules of same material.
Other factors include interfacial surface tension; intimate tissue contact; border seal; atmospheric pressure; neuromuscular control.
Complete Denture Retention = resistance to displacement of denture base away from ridge.
Include principles of adhesion and cohesion.
Adhesion = attraction b/t unlike molecules.
Cohesion = force b/t molecules of same material.
Other factors include interfacial surface tension; intimate tissue contact; border seal; atmospheric pressure; neuromuscular control.
..] Law = living bone responds to functional stress by depositing bone in areas of stress.
**Wolff’s **Law = living bone responds to functional stress by depositing bone in areas of stress.
In complete denture wearers, the mean reduction in anterior […] ridge is 4 times that of the […] ridge.
In complete denture wearers, the mean reduction in anterior mandibular ridge is 4 times that of the maxillary ridge.
Bone of Residual Ridges:
[…] Ridge = partly covered by layer of cortical bone after teeth are extracted.
[…] Ridge = crest remains spongy, trabeculated, and not very resistant to resorption.
[…] shelf (compact bone) of mandible is primary denture support area on mandibular arch.
Bone of Residual Ridges:
Maxillary Ridge = partly covered by layer of cortical bone after teeth are extracted.
**Mandibular **Ridge = crest remains spongy, trabeculated, and not very resistant to resorption.
**Buccal **shelf (compact bone) of mandible is primary denture support area on mandibular arch.
T or F: Dentures are substitutes for natural teeth.

Sodium phosphate = […]
Diatomaceous earth = filler that increases […] and produces […] texture.
What each component of alginate is used for:
Calcium sulfate and potassium alginate = reactors
Zinc oxide = influences setting time
Potassium titanium fluoride = ensures dense, hard stone cast surface
Sodium phosphate = retarder
Diatomaceous earth = filler that increases strength and stiffness and produces smooth texture.
[…] impression = negative restoration of entire denture bearing, stabilizing, and border seal areas present in edentulous mouth.
[…] impression = made for purpose of diagnosis or for construction of a tray.
**Complete denture **impression = negative restoration of entire denture bearing, stabilizing, and border seal areas present in edentulous mouth.
Preliminary impression = made for purpose of diagnosis or for construction of a tray.
[…] impression = exert as little pressure as possible during impression procedures. Capture tissues in most undisturbed/undisplaced form. Uses accurate, free-flowing impression material to increase retention and stability of dentures. Low viscosity, high flow.
Minimal pressure impression = exert as little pressure as possible during impression procedures. Capture tissues in most undisturbed/undisplaced form. Uses accurate, free-flowing impression material to increase retention and stability of dentures. Low viscosity, high flow.
[…] impression = made w/ soft tissue under signficant load. More viscous. Tray is seated and pt closes mouth w/ force while material sets. Denture base-tissue contact during function more intimate if tissue is recorded under compression.
Functional Pressure impression = made w/ soft tissue under signficant load. More viscous. Tray is seated and pt closes mouth w/ force while material sets. Denture base-tissue contact during function more intimate if tissue is recorded under compression.
