研究目的
To address the problem of fabricating temporary teeth restorations through multiple processes which require extensive expertise of dentists and usually result in restorations that do not precisely fit the patient’s teeth due to limited formability of material.
研究成果
The developed TCMIP-SL process can fabricate high viscous temporary crown material with fast speed and high resolution, offering a promising solution for the quick production of customized temporary crowns and bridges in dental offices.
研究不足
The study focuses on the fabrication of temporary crowns and bridges using specific dental composite materials. The process may require further optimization for different materials or more complex geometries.
1：Experimental Design and Method Selection:
The study involved the development of a temperature controlled mask image projection based stereolithography (TCMIP-SL) process for dental materials. The process includes integrating a material coating system with controllable heating to allow the coated thin film of dental composite material to be selectively cured using high resolution patterned light beam.
2：Sample Selection and Data Sources:
Commercial materials commonly used in the dental industry were tested for their photo-polymerization performance. The rheology of photo-curable composite material at different temperatures was studied.
3：List of Experimental Equipment and Materials:
The TCMIP-SL system includes a material coating system with controllable heating, high resolution patterned light beam for curing, and dental composite materials.
4：Experimental Procedures and Operational Workflow:
The process involves heating the dental composite material to reduce its viscosity, coating it into a thin film, and curing it with patterned light beam to build the temporary crown and bridge layer by layer.
5：Data Analysis Methods:
The curing performance and rheology of dental composite material under different temperatures were analyzed to optimize the process parameters.
