Dental Implant Retaining Driver with Rotating Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental implant drivers face challenges in retaining implants in areas with less substantial or thinner bone, leading to the risk of implants being irretrievably lodged in the maxillary sinus, necessitating additional surgery for removal.
Innovation Solution
A dental implant retaining driver with a body and extension portion, featuring a bore with a rotating retaining rod and engagement mechanism that securely locks the implant in place, preventing rotation or removal until a release knob is activated, allowing for safe installation and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional dental implant driver is used, then the implant can be easily installed by rotating into the bone, but the implant cannot be retained securely and may be irretrievably lodged in thin bone areas
Solution Approach 1:
The driver is divided into distinct functional segments: a body portion for manual holding, an extension portion for operating in small oral spaces, a retaining rod within a bore for engagement, and a release knob for controlled release. This segmentation allows each component to perform its specific function while maintaining overall system manageability.
Solution Approach 2:
The retaining rod is configured to rotate relative to the body portion and extension portion, transitioning between engaged and disengaged states. This dynamic mechanism allows the driver to securely retain the implant during installation while enabling controlled release when needed, adapting to different operational requirements.
2Ease of operation
If the extension portion is made smaller in circumference to operate in small oral spaces, then accessibility is improved, but the gripping strength and control may be reduced
Solution Approach 1:
The driver features different circumferential dimensions at different locations: the extension portion has a smaller circumference for navigating small oral spaces, while the body portion has a larger circumference providing better grip and control. This local variation in geometry optimizes both accessibility and operational control.
Solution Approach 2:
The design compensates for the reduced circumference of the extension portion by utilizing the length dimension - the extension portion extends further from the body portion, providing mechanical leverage that compensates for the reduced radial dimension, thereby maintaining sufficient gripping strength and control.
3Reliability
If the retaining rod is configured to rotate within the bore, then the engagement and release mechanism becomes more reliable, but the device complexity increases
Solution Approach 1:
The rotating retaining rod mechanism is designed to be self-actuating through the release knob. When the user rotates the release knob, the retaining rod automatically rotates within the bore to disengage from the implant, and when engaged, it automatically secures the implant without requiring additional locking steps. The mechanism serves itself through simple rotational motion.
Solution Approach 2:
The retaining rod acts as an intermediary element between the release knob and the implant. It translates the rotational motion of the release knob into the engagement/disengagement action, providing a mechanical mediation that simplifies the overall control mechanism while ensuring reliable operation.

AI summary
A dental implant retaining driver apparatus has a body portion and an extension portion extending from the body portion. The extension portion terminating opposite the body portion in a connection region configured to engage a dental implant in a non-rotational relationship. The body portion and the extension portion together have a bore, and a retaining rod in the bore is configured to rotate relative to the body portion and the extension portion. An engagement portion on the retaining rod extends out of the extension portion. The engagement portion is configured to engage the dental implant, such that when the engagement portion and the connection region engage the dental implant, the dental implant cannot be rotated or removed from the apparatus.
