Abstract

Abstract A disposable marking gauge for use in certain orthodontic procedures to mark a patient's tooth with a readily visible mark at the precise location relative to the occlusal surface of the tooth. The marking is especially useful in locating support wire positioning brackets on the patient's teeth so that they can be bonded to the teeth at precise locations relative to the occlusal surfaces of the teeth.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 106 words
A device for use in marking a patient's tooth with an easily visible and removable mark at a precise distance from the occlusal surface of the tooth, comprising a body having a forward portion and a handle portion, said forward portion including: (a) a first portion defining a locating surface engagable by the occlusal surface of the tooth, and (b) a second portion including marking means for marking the surface of the tooth at a fixed distance from the occlusal surface of the tooth, said marking means comprising a marking element that will inscribe on the surface of the tooth an easily discernible, readily removable mark.
Claim 2
Independent Claim 106 words
A device for use in marking a patient's tooth with an easily visible and removable mark at a precise distance from the occlusal surface of the tooth, comprising a body having a forward portion and a handle portion, said forward portion including: (a) a first portion defining a locating surface engagable by the occlusal surface of the tooth, and (b) a second portion including marking means for marking the surface of the tooth at a fixed distance from the occlusal surface of the tooth, said marking means comprising a marking element that will inscribe on the surface of the tooth an easily discernible, readily removable mark.
Claim 3
Dependent Claim 19 words
A device as defined in claim 1 in which said forward portion and said handle portion are longitudinally aligned.
Claim 4
Dependent Claim 40 words
A device as defined in claim 1 in which said marking element includes a body portion and a marking point spaced apart from said locating surface by a first distance, said body portion extending generally parallel to said locating surface.
