Chapter 10 Flashcards
color guide for matching shades
Shade guide
a study model that is a positive duplicate of the patient’s teeth
Model impression
holds whitening chemicals and shaped to fit the study model
Tray fabrication
shielding and protecting the gingivae from whitening chemical damage
Gingival isolation
whitening procedure
Tooth bleaching
acid solution is “painted” onto tooth surfaces
Acid brush
tray filled with gel or paste that is bitten into
Tray method
spreading of whitening gel onto tooth surfaces
Gel application
gel or liquid product is applied to the tooth surface, following the whitening process, to subdue any painful responses to the irritating lightening agents
Tooth desensitization
after tooth surfaces are roughened with a gel etch, a matching shade of composite material is applied to prepared teeth, smoothed and polished
Tooth bonding
tooth surfaces are covered with a porcelain material using one of two techniques:
Veneer or laminate application
similar to tooth bonding, but roughened teeth are covered with a white porcelain, rather than a composite material
Direct application
on a first visit, a small amount of enamel is removed from the teeth, and an impression is taken. The impression is used to make the new veneer cover, and during a second visit, this new covering is applied.
Indirect application
white composite material is used to replace an amalgam or gold filling
Cosmetic tooth restoration
prefabricated white restoration sealed “into” a cavity with cement
Inlay
prefabricated porcelain restoration cemented “atop” occlusal surfaces of posterior teeth or anterior lingual surfaces
Onlay
artificial substitute for the natural crown, with the use of white porcelain.
Dental crown
crown covers the entire tooth’s natural crown area
Full crown
crown covers 3 surfaces of the tooth
Three quarter
crown includes a metal pin inserted into the root to secure retention
Dowel
crown is placed over the anterior tooth like a “jacket”
Jacket
commonly used to make crowns. The top white porcelain layer is fused to the under-layer of gold or metal
PFM (porcelain fused to metal):
crown is a full porcelain crown, built without the use of metals
Procera crown
The amount of gingiva is either surgically reduced, or teeth are treated to give the gingivae a reduced appearance:
Gingival reduction
surgically shaping the gingivae to remove unwanted surplus of gingival tissue
Gingival contouring
exposing more tooth structure, providing the appearance of reduced gingivae
Crown lengthening
surgically excising (cutting) tissue over the crown, to expose the tooth
Exposing un-erupted teeth
Abnormal gingival tissue can be reconstructed or repaired with the addition of more tissue, to provide the appearance of more gingiva:
Gingival augmentation
extracting oral or palatal (palat-al) tissue and ‘relocating’ it to the required gingival area
Soft tissue grafting
adding to the gingival tissue that fills the spaces between the teeth
Interdental augmentation
surgical correction of gingivae that is atrophied (shrunk/shortened/recessed) to the point where the tooth’s apex may be seen
Gingival recession repair
Replacing the gingiva over exposed roots. Similar to repairing gingival recession
Covering exposed roots
eliminating the space between the gingiva and tooth surface
Pocket depth reduction
labial, lingual or buccal sulci are deepened
Ridge extension or augmentation
The dental implant and the bone connect permanently in a process called
osseointegration
the implant is positioned ‘within the bone’.
Endosseous
flat metal plate is screwed onto narrow portions of the jaw
Plate form
metal frame is placed ‘under the periosteum’, and atop the mandible. The periosteum (peri-oste-um) is a thick membrane that surrounds and covers bone
Subperiosteal
plate is positioned ‘through and beyond the bone’ with the post extending through the gingiva
Transosteal or endosteal
