Elastomeric Bite Fork Stabilizer for Accurate Maxillary Arch Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is currently no effective method to stabilize a bite fork in a patient's mouth during dental procedures, which hinders the accurate recording of the maxillary teeth relationship to the cranial base.
Innovation Solution
An elastically deformable bite fork stabilizer with an adhesive layer is attached to the bottom surface of the bite fork, allowing it to be securely positioned in the mouth and stabilized during biting, enabling accurate recording of the maxillary arch relationship.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a bite fork is placed in the patient's mouth to record maxillary teeth relationship, then the maxillary arch relationship can be determined, but the bite fork cannot be stabilized during biting
Solution Approach 1:
An elastomeric stabilizer material is introduced as an intermediary between the bite fork and the patient's teeth. This stabilizer material deforms elastically under biting forces to provide stabilization, while the rigid stabilizing members maintain the structural integrity and positioning of the bite fork during the recording process
2Stability of the object's composition
If a rigid stabilizing structure is added to the bite fork, then stability during biting is improved, but the ability to accurately record teeth imprints is reduced
Solution Approach 1:
The bite fork assembly is designed with different local properties: the stabilizing members are rigid to provide structural stability, while the stabilizer material in contact with the teeth is elastomeric to allow accurate imprint recording. This local differentiation of material properties resolves the contradiction between stability and recording accuracy
Solution Approach 2:
The system combines rigid stabilizing members with elastomeric stabilizer material to create a composite structure that exhibits both structural stability and deformability for accurate teeth imprint recording
3Stability of the object's composition
If complex stabilization mechanisms are added to the bite fork, then bite fork stability is improved, but the device complexity increases
Solution Approach 1:
The elastomeric stabilizer material provides automatic stabilization through its inherent elastic properties when compressed by the patient's biting forces, eliminating the need for complex mechanical stabilization mechanisms. The system self-regulates based on the applied force

Function Achieved in This Case
The stabilizer ensures the bite fork remains stable, allowing for a more accurate representation of the teeth relationship, facilitating precise replication on a mechanical jaw simulator or dental articulator.
