Clinical Indications

Anterior dental aesthetic area implantation

Transalveolar crest maxillary sinus lift

Free end deletion implantation

Immediate implantation

Complete immediate restoration

Implant surgery after fibula reconstruction

Application of Autonomous Dental Implant Robots in Cases of Anterior Maxillary Teeth Loss

Oral Health Overview

Mr. Gu, male, 62 years old, has been missing 22 teeth for 2 years. The alveolar ridge in the edentulous area is well-developed, and there is no obvious collapse on the lip side. The keratinized gingiva is adequate。

Preoperative assessment, Formulation of the plan

Treatment Plan:

The autonomous dental implant robot completes the implant surgery, immediately places the temporary abutment and prefabricated crown, achieving immediate restoration.

Challenges

1、The dental implant robot inserts the implant into the bone surface at an angle (approximately 34.4° between the bone surface and the long axis of the implant).

2、Immediately postoperative placement of the abutment and crown.

Software Planning, Design, and Processing of Components

1. Planning the Position of the Dental Implant
Registration of CBCT and Intraoral Scan
The buccal bone wall hickness around the implant site is greater than 1.5mm
2. Designing and Manufacturing Surgical Accessories
Robot Positioning Board
3D Printed Positioning Board and Saliva Ejector
3. Designing and Manufacturing Immediate Restoration Components
The gingival morphology of immediate dentures is formed by mirroring and flipping the contralateral teeth, creating symmetry with the gingival penetration of corresponding teeth on the opposite side.

Performing the Surgery

Cavity Preparation
Implant Placement (Torque Exceeds 35Ncm)
Trial Placement of Temporary Abutment
Placement of Tooth Crown (Bite Check, Adjustment)

The autonomous dental implant robot system features precision, minimally invasive procedures, safety, and efficiency. With continuous innovation from the research team, the new generation of robot systems is equipped with functions that simulate the tactile sensations of implant surgeons, such as force feedback and visual servoing. Even in the case of complex tilted anterior tooth implants, the system can still precisely complete the surgery. Additionally, the feasibility of a fully digital immediate restoration process for anterior teeth has been validated, opening up new possibilities for the application of digital technology in dentistry.
