Benefits of technology

The patent describes a method for measuring the force exerted on each tooth in a person's dentition. A special rod is used to position a force gauge, which is connected to the person's dentition. A measurement aligner is then applied to the dentition, which is positioned to be received within a cavity of a reference aligner. The force exerted on the dentition by the measurement aligner is then calculated. This method allows for the simultaneous measurement of force on multiple teeth, providing valuable information for dental research and treatment.

Problems solved by technology

Currently, the systems that exist for obtaining such measurements suffer from issues of inaccuracy and their ability to look at multiple teeth and their movements relative to each other.
Thus, it takes much time and effort to obtain a force measurement for multiple teeth within the jaw structure, and any result can rarely be replicated.

Abstract

A method for concurrently measuring a force exerted upon each of a plurality of teeth is disclosed. A dentition crown connecting rod associated with a force gauge is positioned such that a dentition crown coupled to the dentition crown connecting rod may be received within a corresponding cavity of a reference aligner. A measurement aligner is then applied to the dentition crown, wherein the dentition crown is positioned to be received within a corresponding cavity of a reference aligner. A force exerted on the dentition crown by the measurement aligner is then calculated.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to the field of orthodontics.BACKGROUND OF THE INVENTION[0002]Orthodontic treatments involve repositioning misaligned teeth and improving bite configurations for improved cosmetic appearance and dental function. Repositioning is typically accomplished by a dentist or orthodontist (hereinafter practitioner) applying gentle forces by a dental appliance (e.g., braces or positioning appliances) to a patient's teeth over an extended period of time. Due to the limited space within the oral cavity and extensive movements that some teeth must undergo, the teeth will often be moved throughout a series of intermediate patterns to properly arrange the teeth.[0003]Braces comprise a variety of appliances such as brackets, bands, archwires, ligatures, and O-rings. After the brackets are bonded to the teeth, periodic meetings with the treating practitioner are required to allow them to reactively adjust the braces. This generally ...
