Nowadays, computer-aided design/computer-aided manufacturing technology seems to be an interesting way to promote both business and safety, being more comfortable for patients and more accurate than traditional technology. Gypsum casts are frequently contaminated mainly by bacteria and their antibiotic-resistant strains and even stored for long periods during dental implant supported restoration and orthodontic therapy, becoming a hidden source of infection. The transport of impression, to dental laboratories, is often delayed with limited precautions for limiting cross-infection. Some of these contain irritant or non-eco-friendly disinfectants. Effective procedures are available with difficulties. Traditional techniques required disinfecting items (impression, chewing waxes, and appliances) with well-suited products, which are also chosen for limiting impression changes or appliance deterioration. Guidelines for infection prevention in dentistry have been published by Centres for Disease Control and Prevention since 2003 the section “IX-Special consideration” includes a subsection concerning the prevention in dental laboratories, but it has not been modernised in later versions to fit the needs of traditional and computer-aided technology. Recent data indicates limited awareness and compliance on infection prevention procedures by dental offices and by dental laboratories.
