Abstract
|
|
|
One disadvantage of Glass Ionomer Cement Restoration is the difficulty in polishing. To find the appropriate polishing method, we polished the surface of Glass Ionomer Cement Restorations by 11 combination methods serially using disks shard with
large-small particles and evaluated the polishing process in terms of surface roughness, surface roughness curve, and SEM findings.
In addition, a visible light curing type bonding material was applied to evaluate the possible improvement I surface properties.
The following results were obtained.
1. The disk surface of Glass Ionomer Cement was polished serially by disks with superfine particles, but it didn't become smooth.
2. The surface of Microfilled Composite resin became smoother as using a disk with finer particles.
3. When a visible light curing type bonding material was applied in finishing process, the surface of Glass Ionomer Cement became smooth as much as the applied matrix.
