Yizhimei Dental Implant Navigation System
Yizhimei (易植美) represents Dicar’s flagship dental implant navigation platform, having guided over 100,000 implant procedures across China since its commercial deployment in 2017. The system provides real-time visual guidance during implant surgery through active infrared optical positioning technology.
Product Overview
The Yizhimei system delivers computer-aided surgical navigation specifically designed for dental implant procedures. Unlike static surgical guides, the dynamic navigation approach allows dentists to adjust surgical plans intraoperatively while maintaining precision guidance throughout the procedure.
The system addresses clinical challenges in complex implant cases including limited bone volume, restricted mouth opening, and failed previous implant attempts. By providing real-time visualization of drill position relative to planned implant trajectory, surgeons can achieve precise placement while avoiding critical anatomical structures.
Key Features
Yizhimei’s sixth-generation marker-free tracking eliminates patient-worn devices by registering directly to CT data, reducing setup time while maintaining submillimeter implant placement accuracy.
Active Infrared Optical Positioning: International-standard tracking technology provides submillimeter accuracy for instrument localization without line-of-sight restrictions common to passive systems.
Real-Time 3D Visualization: The system displays live drill position overlaid on reconstructed CBCT images, showing the relationship between instruments and anatomical structures during surgery.
Prosthetically-Driven Planning: Integration with digital design software enables implant planning based on final restoration requirements, ensuring optimal emergence profiles and loading angles.
Multi-Region Navigation: Surgeons can navigate between different surgical sites without system recalibration, particularly beneficial for full-arch cases requiring multiple implants.
Sixth-Generation Marker-Free Technology: The 2025 update eliminates patient-worn tracking devices, using direct CT data for registration and reducing setup time significantly.
Technical Specifications

Clinical Applications
The Yizhimei system finds application across the spectrum of implant complexity:
Standard Implant Cases: Provides guidance for routine single-tooth and multiple-implant procedures, reducing reliance on surgeon experience for optimal positioning.
Full-Arch Rehabilitation: Supports edentulous cases requiring precise placement of 4-6 implants for immediate function protocols. Treatment time for full-arch cases can be reduced from 6-8 hours to 3-4 hours.
Complex Anatomical Situations: Particularly valuable for cases involving:
- Severely atrophied ridges
- Proximity to inferior alveolar nerve
- Maxillary sinus involvement
- Zygomatic and pterygoid implant placement
- Failed implant revisions
Immediate Loading Protocols: The precision achieved enables same-day provisional restoration placement, as implants can be positioned according to pre-fabricated prosthesis requirements.

Clinical Evidence
According to the manufacturer, the Yizhimei system has supported:
- Over 100,000 implant procedures (2017-2023)
- Approximately 400 daily procedures (2024)
- Deployment in 600+ hospitals and clinics
Published clinical literature using dynamic navigation systems reports typical deviations of:
- Coronal deviation: 0.85-1.05 mm
- Apical deviation: 1.07-1.11 mm
- Angular deviation: approximately 3°
These figures compare favorably to freehand placement deviations of 1.88 mm (coronal), 2.89 mm (apical), and 8.23° (angular).
Frequently Asked Questions
What procedures can Yizhimei guide?
The system is designed for dental implant placement across all complexity levels, from single-tooth replacements to full-arch rehabilitations. It has been used for standard implants, immediate loading cases, and complex situations including zygomatic and pterygoid implant placement.
How does Yizhimei compare to static surgical guides?
Unlike static guides that are fixed at fabrication, dynamic navigation allows real-time adjustment during surgery while maintaining precision guidance. This provides flexibility to respond to intraoperative findings without sacrificing accuracy.
What is the accuracy of the Yizhimei system?
The system achieves submillimeter accuracy in clinical use. Published studies on dynamic navigation systems report typical deviations under 1.2 mm at the implant platform and under 1.5 mm at the apex, with angular deviations around 3-4 degrees.
