(PDF) Comparison of Accuracy of Current Ten Intraoral Scanners – ResearchGate Insights

Intraoral scanners have revolutionized dental care by enabling quick, accurate, and digital impressions. This article delves into the comprehensive comparison of accuracy of the top ten intraoral scanners based on the latest research available on ResearchGate. If you are a dental practitioner, technician, or an enthusiast wanting to understand how these devices perform, this detailed guide will provide vital insights that can help optimize clinical and laboratory workflow.

Understanding Intraoral Scanners and Their Importance

Intraoral scanners (IOS) are digital devices used to capture direct optical impressions inside a patient’s mouth. Unlike traditional impression materials, IOS offer several advantages:

• Enhanced patient comfort
• Improved clinical accuracy
• Faster turnaround times
• Seamless integration with CAD/CAM technologies

Accuracy, often defined as the combination of trueness and precision, is arguably the most crucial determinant for selecting an intraoral scanner. Trueness refers to how close a scanner’s output is to the actual shape of teeth and tissues, while precision relates to the reproducibility of the scans.

Overview of the Research Study from ResearchGate

The “Comparison of Accuracy of Current Ten Intraoral Scanners” is an empirical study recently published on ResearchGate. This research systematically measured the accuracy of ten leading IOS models available in the market, using standardized clinical and laboratory protocols to benchmark their trueness and precision.

Key objectives of the research included:

• Evaluating each scanner’s trueness against a reference standard
• Assessing precision through repeated scans
• Identifying influence of scanning strategies and operator variability
• Providing quantitative data to guide clinical device selection

Top Ten Intraoral Scanners Compared

Interpreting the Results

The study shows noteworthy variations in accuracy among the scanners. The Dentsply Sirona Primescan and 3Shape TRIOS 4 emerged as top performers with superior trueness and precision, making them favorites for demanding applications like implantology and full-arch restorations. Meanwhile, models like the Runyes RAY IOS are positioned as entry-level options with moderately lower accuracy but greater accessibility for beginners or smaller clinics.

Benefits of Choosing a High-Accuracy Intraoral Scanner

Emphasizing scanner accuracy can dramatically impact clinical outcomes. Some of the key benefits include:

• Precision Fit: Accurately fitting restorations minimize adjustments and remakes.
• Improved Patient Experience: Less chair time and fewer retakes lead to higher satisfaction.
• Streamlined Workflow: Accurate data reduces errors through CAD/CAM integration.
• Cost Efficiency: Reduced material waste and fewer lab callbacks save money long-term.

Practical Tips for Maximizing Scanner Accuracy

To optimize the performance of your intraoral scanner, consider these expert strategies:

• Consistent Scanning Technique: Use methodical scanning patterns to avoid data gaps.
• Operator Training: Skilled operators reduce variability and errors.
• Maintain Device Calibration: Regularly calibrate according to manufacturer guidelines.
• Environmental Control: Minimize saliva, reflective surfaces, and patient movement during scans.
• Software Updates: Keep firmware and scanning apps updated for better algorithms and performance.

Case Study: Impact of Scanner Accuracy on Implant Dentistry

A dental practice specializing in implant restorations adopted the Dentsply Sirona Primescan after reviewing its outstanding accuracy credentials. The practice reported:

• Reduction in trial fittings by 30%
• Improvement in crown seating accuracy within ±15 microns
• Enhanced patient acceptance rates due to shorter appointment durations
• Better lab communication and productivity via seamless STL file transmissions

This demonstrates the tangible benefits of investing in high-accuracy intraoral scanning technology.

First-Hand Experience: What Users Say

According to multiple user reviews gathered on ResearchGate and dental forums, the following observations are frequently mentioned:

• 3Shape TRIOS 4: Praised for fast capturing speeds and reliable data output, excellent for multi-quadrant scanning.
• iTero Element 5D: Widely appreciated for integrating orthodontic and restorative workflows with ease.
• Runyes RAY: Good entry-level price point but limited in large arch full-mouth scans due to slightly lower accuracy.
• Carestream CS 3700: Noted for user-friendly interface and reasonably high accuracy for everyday clinical needs.

Conclusion

Choosing the right intraoral scanner requires careful consideration of accuracy, clinical applications, ease of use, and cost. The ResearchGate study comparing the current ten leading intraoral scanners offers essential data empowering dental professionals to make evidence-based decisions. High-accuracy scanners such as the Sirona Primescan and 3Shape TRIOS 4 come ahead for precision-demanding workflows, yet affordable models still offer respectable performance for general practice.

By understanding the nuances of accuracy and integrating best scanning practices, clinicians can elevate patient care, streamline treatments, and enhance digital dentistry outcomes.
