Shuzhidao Dental Implant Robot

Developed by Shanghai Shuzhidao Robot Co., Ltd., the Dental Implant Surgical Robot received NMPA approval in April 2024, representing the company’s first commercially approved product. The system combines a proprietary six-axis robotic arm with visual servo technology and force feedback sensing to enable autonomous dental implant positioning within the confined oral cavity.

Product Overview

The Shuzhidao Dental Implant Robot addresses the precision demands of oral implantology through autonomous robotic control rather than traditional navigation-guided manual placement. The system integrates surgical planning, real-time tracking, and robotic execution into a unified workflow designed to standardize implant procedures while reducing dependence on individual operator experience.

Unlike dynamic navigation systems that assist surgeons in manual placement, this autonomous system executes implant positioning through direct robotic arm control based on pre-operative planning data. The approach aims to minimize human factors that can introduce placement variability, such as hand tremor or fatigue during extended procedures.

Key Features

Approved by NMPA in April 2024, Shuzhidao’s Dental Implant Robot autonomously positions implants using binocular visual servo tracking and a self-developed six-axis arm with force feedback.

Self-Developed Six-Axis Robotic Arm: The mechanical foundation mimics natural hand movement patterns, enabling operation within the spatial constraints of the oral cavity. Lightweight construction optimizes response speed and maintains consistent performance across extended surgical sessions.

Force Feedback System: Operators receive haptic feedback corresponding to tissue resistance variations, enhancing procedural safety by preventing excessive pressure on oral structures. The system senses micro-force changes during implant placement, reducing risk of damage to adjacent teeth, nerves, or sinus membranes.

Real-Time Patient Tracking: Visual servo technology employing binocular cameras continuously monitors patient position through dedicated oral localization devices. The system compensates for micro-movements during surgery, maintaining targeting accuracy despite patient repositioning.

Immediate Loading Capability: The robot supports immediate post-extraction implantation with same-day loading protocols, enabled by precision placement that ensures optimal primary stability. This capability reduces overall treatment duration and patient chair time.

Technical Specifications

Approved in April 2024, the Shuzhidao dental implant robot uses a six-axis self-developed arm with binocular visual servo tracking for autonomous implant placement in adult patients.

System Components

The complete system comprises:

• Main unit with integrated robotic arm and display screen
• Foot pedal controller
• Binocular vision device
• Oral position locator
• Mobile phone registration device and connector

The modular design enables rapid setup and supports standardized surgical workflows from pre-operative planning through post-operative assessment.

Clinical Applications

The dental implant robot addresses several clinical scenarios in oral implantology:

Single Tooth Replacement: Standard single-unit implant cases benefit from consistent angulation and depth control, particularly in aesthetically critical anterior regions where precise positioning affects final restoration outcomes.

Edentulous Rehabilitation: Full-arch implant cases requiring multiple implants with coordinated positioning use the robot’s ability to maintain planned spatial relationships between fixtures. The system supports posterior bicortical fixation strategies for immediate loading protocols.

Sinus-Adjacent Placement: Upper posterior implants near the maxillary sinus benefit from force-controlled advancement that reduces sinus membrane perforation risk. The system’s position tracking compensates for anatomical variations encountered during osteotomy preparation.

Regulatory Status

The NMPA registration covers the system’s use in adult dental implant surgery for positioning and navigation during implant body placement.

Frequently Asked Questions

What procedures can the Shuzhidao Dental Implant Robot perform?

The robot is approved for adult dental implant placement procedures, including single implants, multiple implants for partial edentulism, and full-arch rehabilitation. The system supports immediate post-extraction implantation and immediate loading protocols when clinical conditions permit.

How does this robot differ from dental navigation systems?

Traditional dynamic navigation systems provide visual guidance while surgeons perform manual placement. The Shuzhidao system is autonomous, meaning the robotic arm directly executes implant positioning based on pre-operative planning. This reduces variability from human factors such as hand tremor or fatigue.

What is the positioning accuracy of the system?

The visual servo tracking system combined with the six-axis robotic arm achieves high-precision implant placement. Clinical studies with similar autonomous dental robots report plant-point deviations under 1mm and angular deviations around 1-2 degrees, though specific accuracy data for this system should be confirmed with the manufacturer.
