[Finals] Matching Type Flashcards
Provisional crowns that are made from impression of a corrected study cast.
Over-impression fabricated
A groove made by use of a no. 170 bur in the canal orifice, it has an anti-rotation function same as that of a second canal.
Keyway
The root of the mandibular 2nd molar to be saved when it is the last tooth in the arch and it can serve as a stop for the opposing occlusion.
Mesial root
The type of cement that is not indicated for permanent cementation for indirect restorations.
Zinc oxide eugenol
Teeth with this characteristic are poor candidates for an all-ceramic crowns because they do not have enough preparation length to support the lingual and incisal surfaces of the restoration.
Short cervical crown
The vertical concavity on the common root trunk of teeth with multiple roots.
Flute
Cements that are composites made of bis-GMA or diurethane methacrylate. They differ from restorative composition primarily in their lower filler content and lower viscosity.
Resin
Cement that adheres to enamel and dentin with good biocompatibility. It is more translucent than zinc phosphate cement.
Glass ionomer
Use of this cement requires layers of copal varnish that can partially seal the dentinal tubules and protects the pulp from phosphoric acid.
Zinc phosphate
Cement that has a low pH but causes little pulpal irritation due to its large size acid molecules. It can bond to stainless steel but not to gold.
Polycarboxylate
It is the bur recommended for the initial labial reduction on an all-ceramic or metal-ceramic crown?
Flat-end diamond
Any horizontal ridge on the facial or lingual surface that intersects the vertical concavity of posterior tooth can become a _____________ and it may be difficult to clean.
Plaque-retaining area
Type of resins that has been used the longest in making custom temporary restorations.
Polymethyl methacrylate
A procedure in which the tooth is separated through the crown down to the root division that produces two essentially equal-sized teeth.
Hemisection
Sharp angles of the preparation should be slightly rounded to reduce the danger of fracture caused by points of ___________.
Stress concentration
The second set of guide grooves that is made parallel to the incisal ⅔ of the uncut labial surface of the incisor is how many?
Two grooves
It is used as a guide and easy reference for tooth reduction. Without it, time may be wasted in repeated checks for clearance.
Depth-orientation grooves
The function for the concave cingulum reduction and the rounded angles on all-ceramic crown preparation is for the purpose of ______________.
Structural durability
The labial surface for a crown preparation on a maxillary incisor is done in _____________ to achieve adequate clearance for good esthetics without encroaching on the pulp.
Two planes
The removal of root without touching the crown.
Root amputation
The process of saving both roots of a mandibular molar after resection.
Bicuspidization
Fracture that usually occurs when a tension is produced on an all-ceramic tooth restoration.
Half-moon fracture
Thermal irritation or chemical irritation on a freshly cut dentin by a polymerizing resin is caused by _________________.
Free monomer
The tooth structure found in the root trunk of maxillary molars connecting the distofacial and palatal roots.
Bridge
This restoration is more difficult to handle due to their small size. The occlusal anatomy and marginal refinements can be done intraorally with a cone-shaped white stone under heavy pressure.
Gold inlay
The part of the axial contour that extends from the base of the gingival sulcus past the free margin of the gingiva.
Emergence profile
This is where the common root trunk divides into two or three roots.
Furcation
Discoloration of an acrylic material used for temporary restoration can be lessened by _________________.
Polishing of the material
The other name for root resection.
Radectomy
Found on the area where the root divides in 73% of mandibular molars.
Intermediate bifurcation ridge
