This invention is designed to facilitate the efficient and minimally traumatic extraction of teeth by optimizing the extraction trajectory. The device includes a tooth gripper mechanism, a central differential system, and a force transfer mechanism, all controlled by an actuator screw. This innovative design aims to reduce tissue trauma and extraction effort, making it easier and quicker for dentists to perform extractions.

Conventional tooth extraction methods using forceps and elevators often lead to fractures in the alveolar bone, causing additional post-operative trauma and hindering immediate dental implant placement. Existing devices with unidirectional pulling are not effective for teeth with curved roots or complex root anatomy, and they typically involve large setup times and a steep learning curve for dentists.
- Optimized extraction trajectory: The innovation utilizes a central differential gear system to achieve an optimal extraction path with minimal resistance.
- Differential displacement: It allows different displacements for extraction arms based on the resistance faced by the periodontal ligament and root anchorage.
- Minimal controls: The device is easy to use with only two main controls (actuator and gripping screws).
- Efficient gripping mechanism: It features a revolute joint for self-adjusting grippers that conform to tooth curvature.
