Comparison of Direct Restorative Dental Materials
We will discuss the following : General Description, Principal Uses, Leakage and Recurrent Decay, Clinical Considerations,
Resistance to Wear, Resistance to Fracture, Post Placement Sensitivity, Esthetics, Relative Cost to Patient
and finally Average Number of Visits To Complete
SECOND PART
COMPOSITE
Direct and Indirect
General Description: A mixture of submicron glass filler and acrylic that forms a solid tooth-colored restoration. Self- or light-hardening at mouth temperature
Principal Uses: Esthetic dental fillings and veneers
Leakage and Recurrent Decay: Leakage low when properly bonded to underlying tooth; recurrent decay depends on maintenance of the tooth-material bond
Clinical Considerations: Must be placed in a well-controlled field of operation; very little tolerance to presence of moisture during placement
Resistance to Wear: Moderately resistant, but less so than amalgam
Resistance to Fracture: Moderate resistance to fracture in high-load restorations
Post-Placement Sensitivity: Occurrence of sensitivity highly dependent on ability to adequately bond the restoration to the underlying tooth
Esthetics: Mimics natural tooth color and translucency, but can be subject to staining and discoloration over time
Relative Cost to Patient: Generally Moderate; actual cost of fillings depends on their size and technique
Average Number of Visits To Complete: One for direct fillings; 2+ for indirect inlays, veneers and crowns
In the end, I thank you and wish you interest
