Remebot Dental Robot

The Remebot Dental Robot (瑞医博®) achieved NMPA approval in 2021 as China’s first oral surgery robot, extending Beijing Baihui Weikang’s navigation technology into dental implantology. The semi-active system tracks patient movement at 1,000 Hz while automatically controlling drill position and trajectory during implant site preparation.

Product Overview

Developed from the same optical navigation platform as Remebot’s neurosurgical robots, the dental implant system addresses the precision demands of oral surgery within the constrained workspace of the mouth. The robot standardizes implant procedures, reduces learning curves for practitioners, and expands indications for immediate implantation and complex positioning.

The system operates as a semi-active robot—automatically performing osteotomy preparation and implant placement while requiring operator guidance for arm entry and exit from the oral cavity. This classification places it between passive navigation-only systems (like YOMI) and fully autonomous robots (like Yakebot) in terms of operational independence.

A wholly-owned subsidiary, Beijing Ruiyibo Technology Co., Ltd., operates the dental product line with dedicated R&D and commercial teams. In March 2025, an updated dental navigation device received additional NMPA approval.

Key Features

Remebot Dental’s 1,000 Hz optical tracking detects patient movement to 0.1 mm sensitivity, automatically repositioning the drill to maintain planned osteotomy trajectories during implant placement.

• High-Frequency Optical Tracking: Position monitoring at 1,000 Hz captures patient movement with 0.1mm sensitivity, enabling real-time trajectory compensation even under local anesthesia when patients may shift

• Automatic Position Adjustment: Once the robotic arm enters the mouth (guided by operator), the system automatically positions the handpiece according to the preoperative plan

• Force Sensing: Integrated force feedback allows surgeons to easily maneuver the handpiece within the limited oral workspace while maintaining safety limits

• Following Function: Continuous position monitoring ensures the system maintains lock on the planned trajectory despite patient movement during the procedure

• Standardized Workflow: Reduces procedural variability and shortens the learning curve for implant placement

Technical Specifications

Remebot Dental’s 1,000 Hz tracking and 0.1 mm movement detection enable semi-active implant placement with ≤0.5 mm positional accuracy and ≤1° angular deviation.

Clinical Applications

Single Implant Placement Standard implant surgery with enhanced precision for both straightforward and anatomically challenging positions.

Multiple Implant Procedures Reduced surgical time for cases requiring several implants, with consistent accuracy across all positions.

Immediate Implantation and Loading The high precision expands indications for placing implants at the time of extraction and immediate prosthetic loading.

Complex Position Implants Navigation assistance enables reliable placement in sites with limited bone, proximity to critical structures, or challenging angulation requirements.

Clinical Evidence

Published clinical studies demonstrate the Remebot dental robot’s accuracy:

Yang et al. (2023) - Case series of 10 patients with single implants:

• Mean coronal deviation: 0.74 ± 0.20mm
• Mean apical deviation: 0.73 ± 0.20mm
• Mean angular deviation: 1.11 ± 0.33°
• No adverse events or postoperative complications

Yang et al. (2022) - Full-arch immediate loading case (6 implants, edentulous maxilla):

• Mean coronal deviation: 0.59 ± 0.24mm
• Mean apical deviation: 0.61 ± 0.23mm
• Mean angular deviation: 0.89 ± 0.38°

Xu et al. comparative study - Comparing autonomous (Yakebot), semi-active (Remebot), and passive (DentRobot) systems in vitro:

• Remebot preparation time: 1.65 ± 0.19 minutes
• Coronal deviation: 0.31 ± 0.10mm
• Apical deviation: 0.36 ± 0.12mm
• Angular deviation: 0.43 ± 0.14°

These results demonstrate accuracy comparable to or exceeding benchmarks established for human-operated static and dynamic computer-assisted implant surgery.

Frequently Asked Questions

What type of dental implant robot is Remebot?

Remebot Dental is classified as a semi-active implant robot. It automatically performs osteotomy preparation and implant positioning once inside the mouth, but requires the surgeon to guide the robotic arm in and out of the oral cavity and to change surgical instruments.

How accurate is the Remebot dental robot?

Clinical studies report mean deviations of approximately 0.74mm coronally, 0.73mm apically, and 1.11° angularly for single implant placement. These figures are comparable to or better than benchmarks for traditional computer-assisted implant surgery.

How does Remebot Dental compare to YOMI?

YOMI (FDA-approved in 2017) is a passive/haptic system where the surgeon maintains continuous control while receiving physical resistance feedback from the robot. Remebot operates semi-autonomously, taking over drill control once positioned. Both achieve sub-millimeter accuracy, but Remebot’s approach reduces surgeon fatigue during longer procedures.

Is the Remebot dental robot available internationally?

Currently, the Remebot dental robot has NMPA approval for the Chinese market. International regulatory status (CE Mark, FDA clearance) has not been publicly confirmed.

What is the relationship between Remebot and Ruiyibo?

Beijing Ruiyibo Technology Co., Ltd. (瑞医博) is a wholly-owned subsidiary of Beijing Baihui Weikang Technology (Remebot’s parent company). Ruiyibo operates the dental robot product line independently with the brand name “Remebot Dental Robot.”
