Restorative Anterior procedures Flashcards
(44 cards)
What are inlays?
Cover a portion of the occlusal and proximal surfaces
What are Onlay‘s?
Covers proximal surfaces and most of the occlusal surface
What does a crown cover?
Covers the full tooth
What are Bridges?
A few teeth connected with the Pontic in the center
What are veneers?
Covers the front portion of a tooth. Cemented on the front of the tooth
What are composites?
Tooth colored restorations
Which type of restorations are used if aesthetics or an issue?
Composite restorations
What type of composites are used to replace missing tooth structure and/or modify tooth color and contour to enhance facial aesthetic’s?
Resin composites
Which type of Restorative material actually reacts chemically with the tooth without acid etching?
Glass ionomer’s
What is resin in dentistry?
Reinforced polymer used for restoring enamel and Dentin
What are resin composites used for?
- Anterior tooth restorations
- Class three restorations- inter-proximal cavities in incisors and pre-molars that do not involve the incisal edge
- class for end inter-proximal carries in incisors that involve the incisal edge
- class 5N carries on the gingival third of the teeth
Describe G.V.black class I caries
Cavity in pits or fishers on the includes all surfaces of molars and pre-molars; facial and lingual surfaces of molars; lingual surfaces of maxillary incisors
Surfaces of posterior teeth you can clinically see
Describe G.V.black class II caries
Cavity on proximal surfaces of pre-molars and molars
Surfaces of a posterior tooth you cannot see clinically
Describe G.V.black class III caries
Cavity on proximal surfaces of incisors and canines that do not involve the incisal angle
Surfaces of an anterior tooth you cannot see clinically
Describe G.V.black class IV caries
Cavity on proximal surfaces of incisors or canines that involve the incisal angle
Larger version of class III that covers the incisal angle
Describe G.V.black class V caries
Cavity on the cervical third of the facial or lingual surfaces of any tooth
Think of the neck of the tooth
Describe G.V.black class VI caries
Cavity on incisal edges of anterior teeth and cusp tips of posterior teeth
Corresponds to the very top surface of a tooth
What are the two different forms of manufactured dental composites? How do they come ?
Self curing and light curing
Come in syringes, comp yours, or in spills
What are composites made of?
Mixture of two different classes of materials. Often called resins and may have glass particles as fillers. Contain pigments and chemicals that start the hardening process
Finer particles are coated with a coupling agent- silane
What are mini fills?
Small, fine particles
What are mid fills?
Larger particles, more strength made up of courts and other glasses containing barium, aluminum, zinc etc.
What is the shelf life of hybrid composites when stored correctly?
Two years or longer. Heat or exposure to operatory lights can cause chemicals to react so light cured materials must be stored in the refrigerator.
Less important for self curing materials
What do manufactures add to each paste to delay polymerization? What will this allow?
They add an inhibitor molecule
Provides ample working time of the material and ensures that the material will not prematurely harden during storage
How are composites handled and mixed?
materials are folded into one another on a pad with a spatula for 15-20 sec
Working time is 1.5-2min after mixing. Setting takes place 4 min from start of mixing (quicker if in the mouth)
