The Dexis IS 3800 (formerly under the DEXIS brand) is the flagship wired intraoral scanner from Envista Holdings, the dental company spun out from KaVo Kerr Group. It inherits the technical lineage of Carestream Dental's highly regarded CS 3600 / CS 3700 / CS 3800 series.
Product Background
Carestream Dental built a solid reputation in Europe and North America with its CS 3xxx intraoral scanner family. After Envista acquired Carestream Dental's imaging business in 2022, the scanners were rebranded under the Dexis name. The IS 3800 (wired) and IS 3800W (wireless) remain core models in the current lineup, positioned alongside the newer Dexis Imprevo flagship launched in 2025.
Key Technical Features
• Structured-light imaging with true-color scanning
• Ultra-lightweight handpiece (190 g for the wired IS 3800; ~240 g including battery for the wireless version)
• Autoclavable interchangeable tips (normal, side, and posterior) rated for up to 110 sterilization cycles at 134 °C
• Wired USB Type-C connection for stable, continuous power (wireless version available)
• Enlarged field of view (16 × 14 mm) and depth of field (–2 to +16 mm)
• Anti-fog technology via airflow
• Gesture motion control and on-handpiece buttons for intuitive operation
• Single-arch scan times as fast as ~25 seconds (in-vitro testing)
• Open STL / PLY / OBJ export
• Seamless integration with the broader Dexis imaging ecosystem (CBCT, 2D imaging) and Envista's DTX Studio Clinic software
• Supports restorative, orthodontic, implant, denture, and sleep-apnea workflows
The scanner's ergonomic design (Studio F. A. Porsche collaboration) and autoclave-friendly tips are frequently highlighted strengths.
Market Positioning
The IS 3800 is positioned in the mid-to-premium segment. Its strongest differentiator is deep integration within the Envista ecosystem-particularly with Nobel Biocare implant systems and Spark clear aligners. Clinics already invested in KaVo, Nobel Biocare, or other Envista products often find the workflow synergy attractive.
Performance in the China Market
Dexis (and previously Carestream) has maintained a relatively modest market share in China. Local after-sales service networks, localization of software, and competitive pricing lag behind leading international brands such as 3Shape and Medit, as well as strong domestic manufacturers. The higher price point further limits its appeal for many Chinese clinics seeking maximum value and rapid local support.
Who Is the Dexis IS 3800 Best Suited For?
• Practices already operating inside the Envista / Nobel Biocare / KaVo ecosystem (especially in Europe and North America)
• Clinics that prioritize autoclave-sterilizable tips, stable wired connectivity, and seamless CBCT integration
For clinics that need broader third-party lab flexibility, lower total cost of ownership, or stronger local service in Asia, open-platform alternatives frequently offer a more practical long-term solution.
