Because of the wide selection of dental porcelain furnaces on the market and the resultant confusion, the Dental Investigation Service DIS undertook this study to offer USAF dental clinics information to aid them in their selection of the best unit for their particular requirements. This report compares the capabilities and features of these furnaces. The information from this report can be used by dental clinics to assist in the selection of porcelain furnaces to meet their particular requirements. The evaluators grouped all porcelain furnaces into three categories automatic, manual, and glazing. They also arranged the vacuum pumps into a separate table. The following criteria were developed by USAFSAM evaluators to compare the units against the most desired and required features. Keywords Dental porcelain ovens Dental glazing ovens Dental equipment.
