Current status and clinical considerations of intraoral scanners (IOS) and digital impression techniques in fixed prosthodontics treatment

Key Points

• The aim is to evaluate the current status, techniques, and clinical implications of intraoral scanners in fixed prosthodontics.
• Comprehensive analysis of the measurement principles of intraoral scanners.
• Comparison of digital impressions with traditional methods.
• Discussion on factors affecting accuracy and clinical decision-making based on case characteristics.
• Intraoral scanners demonstrate equivalent or superior precision for single crowns and small bridges compared to traditional methods.
• Improved patient comfort and reduced chair time are significant advantages of digital workflows.
• Cautions are necessary for widespread defects and deep subgingival cases, emphasizing the need for proper clinical techniques.
