METHODS AND SYSTEMS FOR FABRICATING DENTAL APPLIANCES HAVING VARIABLE STIFFNESSES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240008956 titled 'METHODS AND SYSTEMS FOR FABRICATING DENTAL APPLIANCES HAVING VARIABLE STIFFNESSES

Simplified Explanation

The patent application describes methods for fabricating dental appliances and associated systems. The method involves defining multiple cross-sections of the dental appliance and sequentially polymerizing them to create the appliance. The dental appliance includes an outer shell with teeth-receiving cavities and an inner structure attached to the inner surface of the shell. The outer shell has a higher stiffness than the inner structure. The sequential polymerization process involves simultaneously forming the outer shell and the inner structure.

  • The method involves defining and polymerizing multiple cross-sections to create a dental appliance.
  • The dental appliance consists of an outer shell with teeth-receiving cavities and an inner structure.
  • The outer shell has a higher stiffness compared to the inner structure.
  • The sequential polymerization process allows for the simultaneous formation of the outer shell and inner structure.

Potential Applications:

  • Fabrication of dental appliances such as dentures, retainers, or aligners.
  • Customization of dental appliances for individual patients.
  • Improved fit and comfort of dental appliances due to the combination of outer shell and inner structure.

Problems Solved:

  • Traditional methods of fabricating dental appliances may not provide optimal fit or comfort.
  • Difficulty in creating dental appliances with varying stiffness levels.
  • Limited customization options for dental appliances.

Benefits:

  • Enhanced fit and comfort of dental appliances due to the combination of outer shell and inner structure.
  • Improved customization options for dental appliances.
  • Efficient and streamlined fabrication process for dental appliances.


Original Abstract Submitted

methods for fabricating dental appliances and associated systems are provided. in some embodiments, a method includes defining a plurality of object cross-sections of a dental appliance, and sequentially polymerizing the plurality of object cross-sections to create the dental appliance. the dental appliance can include an outer shell having a plurality of teeth-receiving cavities, and an inner structure coupled to an inner surface of the outer shell. the outer shell can have a first stiffness, and the inner structure can have a second stiffness less than the first stiffness. the sequential polymerization can include integrally forming the outer shell concurrently with the inner structure.
