BACKGROUND: Gold alloy has long been used in dentistry for the fabrication of cast restorations due to its material and clinical properties and known excellent longevity over long-term follow-up. The cost of gold has increased dramatically in recent years (by 450% in the past ten years). The use of base metal alloys as an alternative would lead to a considerable cost saving: a cobalt chromium alloy is around 98% cheaper than gold alloy at the time of writing. NHS regulations state which alloys are permissible for use in cast restorations in dentistry, and certain 'non-precious gold' alloys should not be used. MATERIALS AND METHODS: A prospective audit was carried out in our unit into the standard of cast restorations in cobalt-chromium alloy. The standard set before the audit was established by a prior audit of gold alloy restorations with measures of clinical and technical factors. RESULTS: Base-metal alloy restorations were considerably cheaper; but were of a poorer clinical standard than gold-alloy and required more frequent adjustment and remake (17% compared to 5%).
