This study presents a 3D-printed sleeveless guide system for safe and efficient fiber-post removal. The novel system guides the handpiece, improving clinical outcomes in dental procedures.
Area of Science:
- Dental Technology
- Biomaterials Engineering
- Surgical Instrumentation
Background:
- Fiber-post removal can be challenging, posing risks to tooth structure.
- Existing methods may lack precision, potentially leading to complications.
- A need exists for improved, minimally invasive fiber-post retrieval techniques.
Purpose of the Study:
- To develop and evaluate a novel three-dimensional printed assembled sleeveless guide system.
- To enhance the safety and efficiency of fiber-post removal procedures.
- To provide a precise guidance mechanism for dental handpieces.
Main Methods:
- Acquisition of dentition data using optical scanners and cone-beam computed tomography.
- Design of a 3D-printed guide system with a cylindrical passage for virtual path determination.
- Assembly of the guide system using split parts, pin/jack structures, and connectors.
- Fabrication of the guide system components using titanium alloy.
- Testing the system for fiber-post removal from an upper right central incisor.
Main Results:
- Successful development of an assembled sleeveless guide system.
- Demonstration of safe and efficient fiber-post removal using the guide system.
- The system effectively guided the handpiece, not the rotary instrument.
- Titanium alloy printing ensured durability and biocompatibility.
Conclusions:
- The 3D-printed assembled sleeveless guide system offers a safe and efficient method for fiber-post removal.
- This novel approach enhances procedural precision by guiding the handpiece.
- The technology holds potential for improving clinical outcomes in endodontic retreatment.
