Systems and methods for manufacturing personalized oral care devices

Abstract

Disclosed herein are systems and methods for providing personalized oral irrigation. One variation of a method of generating a model of an oral insert including a fluid inlet port, fluid nozzles, manifolds, and a tray configured to retain teeth may comprise the steps of displaying a graphical representation of the oral insert model, generating a geometry of the fluid nozzles based on oral scan data of a jaw, defining a tray surface that encloses the fluid nozzles based on the oral scan data, generating a geometry of the manifolds that connect the fluid inlet port to the fluid nozzles on the graphical representation of the oral insert model. The manifolds are configured to provide a predetermined range of hydraulic pressures to each of the fluid nozzles.
