Process and resulting product for matching a mouthpiece for cleaning teeth to a user's oral geometry

摘要

A method and the resulting product for optimizing the configuration of a mouthpiece for cleaning teeth in which the configuration of the mouthpiece is optimized to the oral geometry of individual users. The method includes a first step (26) of producing a digital scan of the oral geometry of the individual user and then producing a rigid shell (30) for the mouthpiece substantially matching the digital scan. The configuration of the resulting mouthpiece is characterized by the outer surface of the shell not extending from the buccal surface of the individual teeth more than 7 mm (31); further, by the rear edge of the shell not contacting the tissues to the rear of the rearmost teeth (36), and still further by no more than a 2 mm overlap into the gum line (36), when the mouthpiece is operatively positioned in the user's mouth.

主权项

1. A method for optimizing the configuration of a mouthpiece appliance for oral cleaning to the oral geometry of an individual user, comprising the steps of:
scanning the oral geometry or portions thereof of an individual user; and producing a rigid shell member of two portions for the mouthpiece substantially matching the oral geometry scan, an upper tray portion to receive the teeth in the upper jaw and a lower tray portion to receive the teeth in the lower jaw, wherein the resulting shell is configured and/or trimmed so that an outer surface of the shell does not extend more than 7 mm from the buccal surface of at least the back three teeth of the user's jaw, a rear edge of the shell does not come into contact with tissues to the rear of the rearmost teeth in the user's mouth upper and lower edges of the mouthpiece do not extend more than 2 mm into the gum line of the user, when the mouthpiece is operatively positioned in the user's mouth, and the two tray portions of the shell are angled relative to each other to match the angle of the user's jaws when the mouthpiece is operatively positioned in the user's mouth.
