Dental Post Canal Guide With Puncturable Shell for Root Canal Shaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endodontic file insertion methods are prone to misguidance, causing unintended dentin removal and potential perforation of root canals during root canal cleaning and shaping, leading to periodontal tissue damage and aesthetic issues.
Innovation Solution
A dental post kit comprising a post with a central canal and a thin shell, along with an endodontic file that punctures the shell to access the canal, allowing precise cleaning and shaping of the root canal while preventing preexisting adhesive cement entry and guiding the file's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If tactile sensation guidance is used for endodontic file insertion, then the procedure can be performed without additional guidance systems, but the file may move in the wrong direction causing unintended dentin removal
Solution Approach 1:
The patent introduces a post as an intermediary tool between the endodontic file and the root canal. The post serves as a guide that the file follows during insertion, preventing deviation from the correct path. This mediator ensures precise file placement without requiring complex real-time guidance systems, resolving the contradiction between simplicity and precision.
Solution Approach 2:
The post is pre-formed with a central canal that defines the exact path the endodontic file should follow. By preparing the post structure in advance with the correct geometry and dimensions, the system ensures precise file insertion without needing complex intraoperative guidance mechanisms, thus achieving both simplicity and precision.
2Productivity
If endodontic file is inserted without a guiding post, then the procedure is simpler and faster, but perforation of the root canal may occur causing periodontal tissue damage
Solution Approach 1:
The post acts as a protective intermediary that guides the endodontic file safely through the root canal. Its structured design with a central canal ensures the file remains centered and follows the correct path, preventing perforation and protecting periodontal tissue while maintaining procedural efficiency.
Solution Approach 2:
The post is inserted beforehand to create a protective pathway that cushions and guides the endodontic file during insertion. This pre-prepared guide structure prevents sudden deviations that could cause perforation, ensuring root canal integrity without slowing down the procedure.
3Reliability
If the post has a thin shell covering the second opening, then preexisting adhesive cement cannot enter the internal central canal, but the file must puncture the shell to access the canal
Solution Approach 1:
The thin shell is pre-formed as part of the post structure, creating a sealed barrier that prevents adhesive cement contamination before the procedure begins. The shell's predetermined location and dimensions allow for controlled puncturing by the endodontic file, ensuring both sealing integrity and operational feasibility.
Solution Approach 2:
The post incorporates a thin shell that provides a barrier against adhesive cement entry while remaining thin enough to be punctured by the endodontic file. This thin film structure maintains the sealing function during storage and handling, then allows controlled access when the file deliberately punctures the shell at the second opening.

AI summary
A dental post kit is provided. The dental post kit includes at least one post having a first section and a second section, where the first section has a first opening, and the second section has a second opening covered by a thin shell. An internal central canal extends from the first opening to the second opening. A stopper is mounted on the at least one post and is located between the first section and the second section. At least one endodontic file is included in the kit. The at least one endodontic file is configured to be inserted into the internal central canal through the first opening and to pass through the second opening by puncturing the thin shell covering.
