Light-Curable Resin Dental Record Base for Interocclusal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for obtaining interocclusal records in dental prosthetics face challenges in ensuring rigidity, accuracy, and stability, particularly for partially dentate patients, due to the use of dimensionally unstable materials and the need for additional implant components.
Innovation Solution
A method involving the use of an impression post integrated with a dental implant, followed by molding a light-curable resin into a cubic shape and attaching it to the dental cast, which is then cured to form a record base device. This device is adjustable to aid in positioning interocclusal record material and can be securely attached to the dental implant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional materials and methods are used for the record base, then the fabrication process is simple, but the rigidity, accuracy, and stability of the interocclusal record are compromised
Solution Approach 1:
The patent changes the material parameter from traditional dimensionally unstable materials to light-curable resin, which provides superior rigidity and dimensional stability. The resin's chemical composition and physical properties are optimized to ensure accurate interocclusal recording while maintaining ease of fabrication through light-curing.
Solution Approach 2:
The record base is constructed as a composite structure combining light-curable resin with reinforcing elements or specific structural designs that enhance rigidity and stability. This composite approach maintains fabrication simplicity while achieving the required mechanical properties for accurate dental recording.
2Measurement precision
If additional implant components are used to ensure accuracy, then the interocclusal record precision improves, but the cost and device complexity increase
Solution Approach 1:
The patent merges the impression post and record base into a single integrated structure. The impression post serves dual functions: capturing the implant position and forming the foundation of the record base. This consolidation eliminates the need for separate components while maintaining high measurement precision through the monolithic structure.
Solution Approach 2:
The light-curable resin record base is designed to perform multiple functions: it provides structural support, ensures dimensional stability, facilitates accurate recording of interocclusal relationships, and can be directly attached to the implant via the integrated impression post. This multi-functionality reduces the overall number of components required.
3Ease of manufacture
If wax occlusal rim is used to capture bite relationship, then the reference for final prosthesis is provided, but the accuracy of interocclusal records is reduced
Solution Approach 1:
The patent changes the material state from soft, deformable wax to rigid, dimensionally stable light-curable resin. The resin maintains its shape and dimensional integrity under occlusal forces, providing both the necessary reference for prosthesis fabrication and high measurement precision for interocclusal recording simultaneously.

AI summary
A dental implant-retained record base device and methods of fabricating thereof are provided, and a method for obtaining an interocclusal record. The method involves inserting an impression post into a dental implant in a partially-dentate patient and capturing a dental impression to obtain a dental cast inclusive of the impression post. A light-curable resin is molded into a cubic shape and subsequently attached to the dental cast at position of the impression post. Upon exposure to visible light, the resin is cured to form a record base device, which is then adjusted to facilitate the positioning of interocclusal record material. The dental implant-retained device constructed from the light-cured resin is configured for attachment to the dental implant for obtaining the interocclusal record for the patient.
