This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,385.

Summary of the Inventive Concept

A revolutionary plate denture production system leveraging advanced 3D printing and curable composition technologies to create highly precise, customized dentures with enhanced mechanical strength and natural tooth-like structures.

Background and Problem Solved

The original patent disclosed a method of producing plate dentures using stereolithography 3D printing. However, the limitations of this method include the lack of precision, limited customization options, and inadequate mechanical strength. The new inventive concept addresses these limitations by introducing a next-generation plate denture production system capable of producing highly precise, customized dentures with advanced structures.

Detailed Description of the Inventive Concept

The new inventive concept comprises a 3D printer capable of printing denture bases with precision of 1 micron or less, a curable composition for stereolithography including a first polymerization initiator for stereolithography and a second polymerization initiator for post-curing, and an artificial tooth. The 3D printer can print denture bases with advanced structures such as gradient structures mimicking natural tooth structures or lattice structures for improved mechanical strength. The curable composition includes a filler with a particle size of 1 nm or less and a photopolymerization initiator with an absorption wavelength of 450 nm or more.

Novelty and Inventive Step

The new claims introduce a paradigm shift in plate denture production by enabling the creation of highly precise, customized dentures with advanced structures, thereby rendering the original patent's method obsolete. The novelty lies in the combination of advanced 3D printing capabilities, curable composition technologies, and artificial tooth integration.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include using different types of 3D printing technologies, such as digital light processing or selective laser sintering, or incorporating additional features such as sensors or microelectromechanical systems (MEMS) into the denture base. Variations of the curable composition may include different polymerization initiators, fillers, or photopolymerization initiators.

Potential Commercial Applications and Market

The next-generation plate denture production system has significant commercial potential in the dental industry, enabling the creation of highly customized, precise, and strong dentures. The target market includes dental clinics, hospitals, and dental laboratories seeking to provide advanced dental care solutions.
