Abstract
Abstract Diagnostic measurements needed to determine the progress of treatment with orthodontic appliances are made with an appliance system comprising at least four gauge members, each gauge member comprising a handle interconnected with opposed pointer members that are maintained in a fixed position relative to each other. Each pointer member has a terminal portion and the distance between the terminal portions of the opposed pointer members of each gauge member defines a different cross-arch width distance or arch length distance between anatomical features of the maxilliary or mandibular arches. Typically, at least two of the gauge members define cross-arch width distances between anatomical features of the maxillary arch and at least two of the gauge members define cross-arch width distances between anatomical features of the mandibular arch.

Claim 1
Independent Claim
105 words
An orthodontic appliance system comprising at least four gauge members, said gauge members each comprising a handle member interconnected with opposed pointer members that are maintained in a fixed position relative to each other, each pointer member having a terminal portion, the terminal portions of the opposed pointer members of said gauge member defining a cross-arch width distance between anatomical features of ideal maxillary and mandibular arch structures, at least two of said gauge members defining cross-arch width distances between anatomical features of the maxillary arch and at least two of said gauge members defining cross-arch width distances between anatomical features of the mandibular arch.
Claim 2
Dependent Claim
105 words
An orthodontic appliance system comprising at least four gauge members, said gauge members each comprising a handle member interconnected with opposed pointer members that are maintained in a fixed position relative to each other, each pointer member having a terminal portion, the terminal portions of the opposed pointer members of said gauge member defining a cross-arch width distance between anatomical features of ideal maxillary and mandibular arch structures, at least two of said gauge members defining cross-arch width distances between anatomical features of the maxillary arch and at least two of said gauge members defining cross-arch width distances between anatomical features of the mandibular arch.
Claim 3
Dependent Claim
118 words
An orthodontic appliance system comprising at least four gauge members, said gauge members each comprising a handle member interconnected with opposing pointer members that are maintained in a fixed position relative to each other, each pointer member having a terminal portion, the terminal portions of the opposed pointer members of said gauge member defining a distance between anatomical features of ideal maxillary and mandibular arch structures, at least one of said gauge members defining a maxillary cross-arch width distance, at least one of said gauge members defining a maxillary arch length distance, at least one of said gauge members defining a mandibular cross-arch distance and at least one of said gauge members defining a mandibular arch length distance.
Claim 4
Dependent Claim
118 words
An orthodontic appliance system comprising at least four gauge members, said gauge members each comprising a handle member interconnected with opposing pointer members that are maintained in a fixed position relative to each other, each pointer member having a terminal portion, the terminal portions of the opposed pointer members of said gauge member defining a distance between anatomical features of ideal maxillary and mandibular arch structures, at least one of said gauge members defining a maxillary cross-arch width distance, at least one of said gauge members defining a maxillary arch length distance, at least one of said gauge members defining a mandibular cross-arch distance and at least one of said gauge members defining a mandibular arch length distance.
