Method for manufacturing a deciduous tooth model

Abstract

Until now, it has been impossible to create models of infant teeth. [Solution] By taking an optical impression of the deciduous teeth that have erupted in infants using an intraoral scanner, and then manufacturing a model using a 3D printer based on that data, it has become possible to manufacture a deciduous tooth model.

Description

Technical Field

[0001] The present invention relates to a technique for making a model of deciduous teeth erupted in infants as a replica. Here, the term "infants" generally means from 0 month after birth to less than 1 year old, but the scope of application of the production method of the present invention is not limited to this age range.

Background Art

[0002] Using a scanner for 3D printers (optical impression), the morphology of deciduous teeth can be scanned and made into models with various materials.

Summary of the Invention

Problem to be Solved by the Invention

[0004] Normally, impression taking of teeth performed in dental clinics and the like is carried out by loading dental impression material onto a dental impression tray, inserting it into the oral cavity, pressing it against the teeth, and holding it until the material hardens. Dental impression materials are classified into two types according to their properties. 1 Elastic impression materials Hydrocolloid impression materials (alginate impression materials, agar impression materials) Rubber impression materials (silicone rubber impression materials, polyester impression materials, polysulfide rubber impression materials) 2 Non-elastic impression materials Impression plaster, modeling compound, zinc oxide eugenol impression materials These impression materials require setting time, which varies depending on the type and manufacturer. For commonly used alginate impression materials, in addition to an initial setting time of 2 minutes, a holding time in the oral cavity of about 1 minute 30 seconds to 3 minutes is required. Furthermore, because of their considerable fluidity, taking impressions of infants' teeth carries risks such as choking. Therefore, it is virtually impossible to create models of infants' primary teeth. [Means for solving the problem]

[0005] This invention relates to a method for manufacturing a deciduous tooth model using a 3D printer, which involves taking an optical impression of an infant's erupted deciduous tooth with an intraoral scanner and using that data. [Effects of the Invention]

[0006] By overturning the notion that it is impossible to create models of infants' primary teeth, and by acquiring three-dimensional information of the oral cavity using an intraoral scanner, it is possible to create models of infants' primary teeth, generating new value as keepsakes. [Modes for carrying out the invention]

[0007] Using an intraoral scanner, optical impressions can be taken without physical contact with the infant, requiring only 30 seconds to 1 minute of oral cavity opening. Furthermore, this data can be used to easily create 3D-printed models of the deciduous teeth.

Claims

[Claim 1] A method for manufacturing a deciduous tooth model using a 3D printer, which involves taking an optical impression of an infant's newly erupted deciduous tooth with an intraoral scanner and using that data.
