Abstract
Abstract A segmented labial bow with lip pads for use in the correction of Class III malocclusions and malocclusions with underdeveloped maxillas. The segmented labial bow with lip pads is attached to a conventional orthopedic/orthodontic appliance. As the orthopedic/orthodontic appliance is activated, the lip pads on the segmented bow hold the upper lip away from the roots of the maxillary anterior teeth and alveolar process allowing skeletal development of the premaxillary area with resultant forward movement of the roots and alveolar bone of the premaxillary teeth.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
118 words
An orthopedic appliance for removing lip pressure from the premaxillary gum tissue for aiding in the correction of Class III type malocclusions comprising: a. a palatal appliance; b. a segmented bow consisting of two segments, each segment attached to opposite sides of a palatal appliance and extending along without contacting the premaxillary gum tissue of a patient between the premaxillary gum tissue and the upper lip to a point of disjuncture of the two segments at the extreme anterior of the premaxillary gum tissue; and c. two pads, each attached at the respective ends of the two segments at the extreme anterior of the premaxillary gum tissue and in contact with the inner surface of the upper lip.
Claim 2
Dependent Claim
118 words
An orthopedic appliance for removing lip pressure from the premaxillary gum tissue for aiding in the correction of Class III type malocclusions comprising: a. a palatal appliance; b. a segmented bow consisting of two segments, each segment attached to opposite sides of a palatal appliance and extending along without contacting the premaxillary gum tissue of a patient between the premaxillary gum tissue and the upper lip to a point of disjuncture of the two segments at the extreme anterior of the premaxillary gum tissue; and c. two pads, each attached at the respective ends of the two segments at the extreme anterior of the premaxillary gum tissue and in contact with the inner surface of the upper lip.
Claim 3
Dependent Claim
24 words
The orthopedic appliance of claim 1 wherein each of the segments of the bow is manufactured of stainless steel chromium-nickel alloys and non-ferrous metals.
Claim 4
Dependent Claim
12 words

Claim 5
Dependent Claim
14 words
The orthopedic appliance of claim 1 wherein the palatal appliance is manufactured of acrylic.
Claim 6
Dependent Claim
13 words
The orthopedic appliance of claim 1 wherein the pads are manufactured of acrylic.
Claim 7
Dependent Claim
87 words
An orthopedic appliance for removing lip pressure from the premaxillary gum tissue for aiding in the correction of Class III type malocclusions comprising: a. a palatal appliance; b. a bow attached to opposite sides of a palatal appliance and extending along without contacting a portion of the perimeter of the premaxillary gum tissue of a patient between the premaxillary gum tissue and the upper lip; and c. a pad attached at the end of the bow and in contact with the inner surface of the upper lip.
Claim 8
Dependent Claim
87 words
An orthopedic appliance for removing lip pressure from the premaxillary gum tissue for aiding in the correction of Class III type malocclusions comprising: a. a palatal appliance; b. a bow attached to opposite sides of a palatal appliance and extending along without contacting a portion of the perimeter of the premaxillary gum tissue of a patient between the premaxillary gum tissue and the upper lip; and c. a pad attached at the end of the bow and in contact with the inner surface of the upper lip.
Claim 9
Dependent Claim
19 words
The orthopedic appliance of claim 6, wherein the bow is manufactured of stainless steel chromium-nickel alloys and non-ferrous metals.
Claim 10
Dependent Claim
12 words
The orthopedic appliance of claim 6, wherein the palatal appliance is removable.
Claim 11
Dependent Claim
14 words
The orthopedic appliance of claim 6, wherein the palatal appliance is manufactured of acrylic.
Claim 12
Dependent Claim
13 words
The orthopedic appliance of claim 6, wherein the pad is manufactured of acrylic.
Claim 13
Independent Claim
163 words
A method for aiding in the influencing of the basal maxilla-mandibular relationship from a Class III type malocclusion to a Class I occlusion by removing lip pressure from the premaxillary gum tissue which comprises: a. forming an orthopedic appliance molded to fit the upper mouth and dentition of the patient to be treated having a segmented bow consisting of two segments, each segment attached to opposite sides of a palatal appliance and extending along without contacting a portion of the perimeter of the premaxillary gum tissue of a patient between the premaxillary gum tissue and the upper lip to a point of disjunction of the two segments at the extreme anterior of the premaxillary gum tissue; b. inserting the orthopedic appliance in the patient's upper mouth; and c. adjusting each of the two segments of the bow outward from time to time during the period of treatment so that the two segments remain in contact with the inner surface of the upper lip.
Claim 14
Independent Claim
163 words
A method for aiding in the influencing of the basal maxilla-mandibular relationship from a Class III type malocclusion to a Class I occlusion by removing lip pressure from the premaxillary gum tissue which comprises: a. forming an orthopedic appliance molded to fit the upper mouth and dentition of the patient to be treated having a segmented bow consisting of two segments, each segment attached to opposite sides of a palatal appliance and extending along without contacting a portion of the perimeter of the premaxillary gum tissue of a patient between the premaxillary gum tissue and the upper lip to a point of disjunction of the two segments at the extreme anterior of the premaxillary gum tissue; b. inserting the orthopedic appliance in the patient's upper mouth; and c. adjusting each of the two segments of the bow outward from time to time during the period of treatment so that the two segments remain in contact with the inner surface of the upper lip.
Claim 15
Dependent Claim
