Cementing Tool for Dental Crown and Titanium Base Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching a crown to a titanium base in dentistry require manual holding until the cement cures, which is time-consuming and prone to human error, and can result in uneven seating due to the difficulty in aligning the titanium base within the crown.
Innovation Solution
A system comprising a handle, threaded rod, and driver tool that allows the crown to be securely attached to the titanium base without manual holding, enabling accurate cementing and easy inspection of the fit, with a hemostat tool as an alternative for clamping until the cement cures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual holding of the titanium base to the crown is used until cement cures, then the crown can be attached to the implant, but the process is time-consuming and prone to human error
Solution Approach 1:
A clamp device is introduced as an intermediary tool to hold the titanium base to the crown during cement curing. The clamp eliminates the need for manual holding by providing mechanical clamping force, thereby reducing human error and freeing the dentist's hands for other tasks while maintaining secure attachment throughout the cementing process.
2Manufacturing precision
If the titanium base is manually held to the crown, then attachment is possible, but the base may not seat evenly due to difficulty in alignment
Solution Approach 1:
The clamp device serves as a mediator that applies uniform pressure to ensure even seating of the titanium base within the crown. By providing consistent clamping force across the interface, the device eliminates alignment difficulties associated with manual holding and ensures precise, uniform contact between the base and crown surfaces.
3Ease of manufacture
If excess cement is present after cementing, then the attachment is complete, but cleaning becomes difficult once the cement hardens
Solution Approach 1:
The clamp device maintains pressure on the crown and base assembly during the cement curing process, ensuring that excess cement is compressed and contained at the margins. This preliminary action of controlled compression during curing makes subsequent cleaning easier, as the cement has already been shaped and contained before hardening, reducing the time and effort needed for cleanup.

AI summary
Tools, assemblies, devices, systems, and methods for easily mounting a crown to a titanium (Ti) base or custom abutment with a tool without having to pre-cement a mounting base to a crown and have to physically hold together the base to the crown until the cement is cured. The implant cementation assembly tool does allow the Ti base and crown to be cemented (pre-cemented) without being constantly held and done outside of the mouth. The embodiments can include a bottom (hard rod, such as plastic or metal) that goes through the Ti base and the crown. The embodiments can include a top that is either threaded to allow it to be screwed onto the hard rod or a top that has a hollow center that can slide over the hard rod and be clamped to the rod. A second embodiment uses a modified hemostat tool with lockable pivoting arms to clamp the crown to the Ti base to allow cement to become set.
