work until it is reactivated.
This Concept Map, created with IHMC CmapTools, has information related to: 03 PostAndCoreCrowns, Glass Ionomer Disadvantages Prone to fracture, Principle of Substitution ???? 2 Rules, adding grooves, Materials for Buildups Amalgam, Glass Ionomer Advantages Released fluoride ions contributes to reduced incidence of recurrent decay, Principle of Substitution a preparation may be modified by adding, treated as tooth structure ???? classic full coverage prep is used, pins types Friction Lock, Composite Resin Disadvantages Poor dimensional stability, Glass Ionomer Advantages Highly ionic nature that have the ability to physicochemically bond to enamel and dentin, Rapid rate of polymerization ???? Allow crown preparation to be done at the same appointment, w/ cavity varnish produces better Resistance to microleakage, Self-threading is the most retentive type, grooves placed in axial walls (applicable for multiple grooves), pins contraindicated when occlusal surface is to be adjusted and there is not enough vertical space for the pin to retain into the amalgam filling., Glass Ionomer Disadvantages Slow set, Amalgam Disadvantages May be harmful for patients w/metal allergies, Retention of Build Up Materials ???? Grooves, 2 Rules 2. No wall of dentin should be reduced to a thickness of less than its height for the sake of retention., half or more of the clinical crown is lost placing of amalgam/composite resin core in the tooth
