Chapter 11 Flashcards
man-made appliances that act as substitutes for damaged or missing teeth
prostheses (plural of prosthesis
non-removable devices
Fixed appliances
devices that can be inserted into, and removed from the mouth
Removable appliances
usually fixed appliances
Dental implants
includes gold, platinum, nickel
Metals
for implants and posts
Titanium
fused to metal crowns to provide natural tooth appearances
Porcelain and PFM
mostly used to cover metal frameworks and act as a base for the denture
Acrylic
non-metal material, fired at a very high temperature, to prefabricate substitute crowns
Ceramic
prosthesis permanently attached to adjacent natural teeth. The natural teeth then provide support to the appliance
BridgeAlso called a fixed partial denture
the artificial tooth that replaces the missing tooth
Pontic
natural tooth that supports and anchors the bridge
Abutment
neighboring teeth may be included in the appliance
Adjacent teeth
substitute for the entire dentition. May be an upper arch, a lower arch, or both
Complete denture
replaces one or more teeth in one arch
Partial denture
prosthesis inserted immediately after removal of natural teeth
Immediate denture
appliance that is supported by implant posts or prepared retained roots
Overdenture
a basic metal foundation to which all other structures are attached
Framework May also be called a stroma
saddle-shaped structure that lies on the gingivae
Saddle
rigid metal structure that fits and rests on top of an adjacent tooth
Rest
stabilizer that partially surrounds an adjacent tooth
Clasp
structure that joins two quadrants of the same arch
Connector
substitutes for natural teeth
Teeth
substitute for gingiva
Base
corresponds to natural tooth’s cervical line (area where enamel and cementum meet)
Flange
area where the maxillary appliance ends on the soft palate
Post dam
surgical removal of portions of the alveolar bone to allow smoothness for proper denture fit.
Alveolectomy
this suffix is a combination of ‘plasty’ and ‘otomy’. Cutting into and repairing, shaping and smoothing alveolar ridges following dental extraction
Alveoplastomy
luxation and removal of teeth
Extraction
refers to dislocating and displacing the tooth
Luxation
thin metal cap on tooth, to which the overdenture will be attached
Coping
removal of surfaces, edges and decay, to accept the appliance
Reduction
enlargement of tooth’s surface area, to accept a post for a fixed crown
Core buildup
insertion of the post
Post placement
creating a small ridge near the gingival edge to accommodate placement of the appliance’s clasp
Undercut
string/cord that may be treated with chemicals to shrink the gingivae prior to taking an impression
Retraction cord
mechanical dental impression, while the teeth are occluded
Bite registration
the patient bites down into the material used to make the impression
Open bite
with the teeth occluded, impression material is ‘infused’ into the mouth, around the teeth
Closed bite
the habitual, resting position
Centric
pushing out the lower jaw to thrust the mandible forward
Protrusion:
backward movement of the lower jaw (mandible)
Retrusion
movement of the lower jaw to the left and to the right
Lateral excursion
