Metal bases for implant overdentures.

Reinforcement of implant overdenture bases with chromium alloys offers a number of advantages that offset the initial greater cost. These bases offer increased strength, the ability to detect thermal changes, and the option for use when space is at a minimum. Both acrylic resin and chromium alloy have long (approximately 80 years), successful histories as accepted dental materials. Low-heat (nickel) or high-heat (cobalt) chromium alloys can be used with equal success.
