Unsurpassed
Strength
Gold offers more compressive and tensile strength than other filling materials.
This allows thin bevels of metal to be placed over margins to protect fragile
enamel walls. Margins do not chip or erode away. While most filling materials
must be protected by the tooth dentin and enamel, cast gold actually protects
the remaining tooth structure. The long-term durability of high gold content
alloys makes them an excellent value for the patient.
Excellent Esthetics
When used appropriately, gold is a very esthetic material. Gold inlays and
onlays will not discolor a tooth nor will they decompose or tarnish. Properly
completed preparations eliminate unwanted metal display. Natural tooth
contours are more easily reproduced in the laboratory than in the mouth
where access is always a consideration. The very smooth finished surfaces
are comfortable for the patient and do not readily harbor plaque.
Preserves Natural
Dentition
Many other restorative materials are harder than gold and may cause abrasion
damage to opposing dentition. Gold's wear resistance is compatible with opposing
teeth. As a malleable material, gold can adapt to occlusal pressures much like
natural dentition. A cast gold inlay or onlay also provides fine, smooth margins
that resist microleakage, significantly reducing secondary decay. There are
few areas in dentistry that require such close cooperation between dentist
and laboratory technician as gold inlays and onlays. Certainly, the procedure
for placing a gold casting has been called technique sensitive. Planning and
preparations must allow for expansion not only of the gold alloy but also for
expansion of the die material and shrinkage of the wax in the pattern. At Aurum
Ceramic/Classic Dental Laboratories, we understand the precision required for
intracoronal castings. Working as a team with the dentist, we can achieve truly
outstanding results in cast gold restorative dentistry. |
