Implant Bite Registration Jig for Simultaneous Impressions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing implant procedures require a separate jig for taking a bite impression, which increases the time and cost of manufacturing the prosthesis, as well as necessitates additional visits to the dental clinic, especially when embedding a tooth root in parallel with the gum surface lacks a rigid structure for impression alignment.
Innovation Solution
An implant bite registration jig with a coupling portion for supporting bite material, a connecting portion that threads onto an embedded fixture, and a body minimizing interference, allowing simultaneous dental and bite impression taking, reducing the need for external jigs and subsequent clinic visits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate jig is manufactured and used for taking bite impression, then accurate bite impression can be obtained, but the time and cost of prosthesis manufacturing increases
Solution Approach 1:
The patent combines the bite registration jig with the implant fixture into a single integrated component. The jig is formed as part of the fixture structure, eliminating the need for a separate jig manufacturing process and reducing overall procedure time while maintaining impression accuracy.
Solution Approach 2:
The bite registration function is built into the fixture during the initial implant placement. The jig is pre-formed with the fixture at the time of embedding, so that when the patient returns for the bite impression, the registration structure is already in place and ready for use, eliminating the need for separate jig fabrication and delivery steps.
2Measurement precision
If a separate jig is manufactured and used for taking bite impression, then accurate bite impression can be obtained, but the number of clinic visits increases
Solution Approach 1:
The patent merges the bite registration function with the implant fixture, combining two separate procedures (fixture embedding and bite impression taking) into a more integrated process. This reduces the number of separate components and steps that need to be managed, thereby reducing procedure complexity even though multiple visits may still be required.
3Ease of manufacture
If fixture is embedded in parallel with gum surface, then implant placement is simplified, but rigid structure for impression alignment is lacking
Solution Approach 1:
The bite registration jig is pre-formed as part of the fixture structure during the embedding process. This preliminary formation of the registration structure ensures that when the patient returns for the bite impression, the alignment references are already in place, providing accurate guidance without requiring additional structural modifications.
Solution Approach 2:
The patent combines the fixture and bite registration jig into a single integrated structure. This merging provides the necessary rigid alignment references directly from the embedded fixture, eliminating the need for separate registration structures and maintaining impression alignment accuracy while preserving the simplicity of parallel embedding.

AI summary
An implant bite registration jig includes a coupling portion configured to produce a clear impression in bite impression material; a connecting portion that connects the implant jig with a fixture embedded in a patient's gums; and a body that is formed between the coupling portion and the connecting portion. The implant bite registration jig is positioned in an embedded fixture and a bite impression is taken. Reference marks are formed in the bite impression material by the registration jig, which permit accurate location of the fixture. This makes it possible to simultaneously take a dental impression and a bite impression in an implant operation, similar to a natural teeth operation, such that it is possible to reduce the cost and time for manufacturing a prosthesis.
