- Abstract
Objectives: The purpose of this systematic review was to assess the effects of remelting dental alloys on the physical and mechanical properties and possible advantages and disadvantages of using the recasted base metal alloys. Study Selection: The systematic review included the studies on dental alloy recasting. MEDLINE, Science Direct, Dentistry and Oral Science Source were searched. Data extracted and the quality of studies were assessed. Data: 44 studies published were reviewed in the current article. The number of recastings for dental alloys ranged from 1 to 10. The percentage of new alloy ranged from 0 to 100 wt%, although the mean value was 50 wt%. The properties like biocompatibility, color, castability, porosities and marginal fit of the recasted alloys. Conclusion: Dental casting alloys have found wide spread usage in restorative dentistry due to their desirable physical, biological and economical properties. The recasting of previously casted alloy is a routine procedure in dental laboratories. The procedure is practiced worldwide mainly due to economic reason and to prevent wastage of natural resources and environmental protection. It will be of definite advantage if the properties of the recast alloys are studied in detail and directions given to Prosthodontist and technicians without compromising the optimum properties of the alloy. Clinical Significance: Recasting of dental alloys is practiced worldwide. This is mainly due to economic reasons and protection of environment. This article reviewed on various properties of dental alloys and recasting could be acceptable only if at least 50% of new alloy should be added during each recasting procedure.
