CEPHALOMETRIC INFERENCE

MAXILLA

Prognathic suggested by readings of SNA of 92 degrees, Effective Maxillary base

length of 100 mm and maxillary base length of 55.5 mm.

MANDIBLE

Prognathic mandible suggested by SNB of 85 degrees , mandibular base length of 80

mm and Ratio of mandible to cranial base is 21.6:19.4.

Page 34: Adita Aggarwal ppt

MAXILLO-MANDIBULAR RELATIONClass IIPattern suggested by ANB of 7 degrees, Wits Appraisal of 2.0 mm,and Facial convexity of 13 degrees .

VERTICAL SKELETAL RELATIONSHIP

Horizontal growth pattern as suggested by Jarabak ratio , FMA and Y Axis.

DENTOALVEOLAR RELATION

Proclined maxillary and mandibular incisors suggested by all the readings.

SOFT TISSUE RELATIONSHIPS

Convex profile with acute nasolabial angle,decreased upper lip thickness, protrusive upper

and lower lips and increased lower lip length

Page 35: Adita Aggarwal ppt

CEPHALOMETRIC INFERENCE:

Skeletal Class II accompanied with tendancy towards horizontal growth pattern, proclined maxillary incisor along with acute nasolabial angle, decreased upper lip thickness, protrusive upper and lower lips and increased lower lip length.

Page 39: Adita Aggarwal ppt

BOLTON’S ANALYSIS Sum of maxillary 12 = 96 mmSum of mandibular 12 = 90 mmSum of maxillary 6 = 48 mmSum of mandibular 6 = 38 mm

Total Tooth Ratio (TTR) = sum of mand. 12 x 100 sum of max. 12 = 90 x 100 = 93.75 % (91.3%) 96

Mandibular Excess = Sum of mand.. 12 teeth – Max. 12 x 91.3 100  = 2.4 mm excess

Page 40: Adita Aggarwal ppt

Anterior Ratio = Sum of mand. 6 x 100 Sum of max. 6 = 38 x 100 = 79.2% ( 77.2%) 48

Amount of anterior mandibular excess = Sum of Mand. 6 – Sum of Max. 6 x 77.2 100 = 38 – 37 mm = 1 mm excess.

INFERENCE•In this patient TTR value is 93.75 %, indicating Mandibular tooth

material excess.

(Amount of total tooth material excess is 2.4 mm)•In this patient Anterior tooth ratio is 79.2 %, hence indicating Mandibular anterior tooth material excess. (Amount of anterior tooth material excess is 1mm)

ORTHODONTIC DIAGNOSIS

Skeletal Class II with convex profile and

tendency towards horizontal growth pattern,

dental Angle’s Class II Subdivision of left side

malocclusion with highly and labially erupting

tooth wrt.23, proclined maxillary incisors along

with acute nasolabial angle, decreased upper lip

thickness, protrusive upper and lower lips and

increased lower lip length.

PROBLEM LISTHighly and labially placed teeth wrt. 23.Proclined maxillary incisorsOverbiteOverjetCanine relation in left sideMolar relation in left side.Midline.

Page 46: Adita Aggarwal ppt

TREATMENT OBJECTIVES

Alignment of maxillary and mandibular anteriors.

To correct canine relationTo correct molar relationTo correct overbiteTo correct overjetTo correct midline

Page 47: Adita Aggarwal ppt

TREATMENT PLANFixed mechanotherapy Moderate anchorage case Unilateral extraction wrt. 44Leveling and aligning:

Correction of rotations. Correction of curve of spee Correction of midline.

Retention

Minimum retention in maxillary and moderate retention in mandibular arch.
