18. •100% incisal show when smiling
• no gingival show
•Smile extends from ur4 to to ul5
19. • Buccal corridors: average
• The smile arc: the contour
of the incisal edges of the
maxillary anterior teeth
does’nt match the curvature of
the lower lip.
27. Class II div. 2 incisor relationship
Midlines : lower midline is deviated to the
right by 2mm
Overjet = 2 mm
Overbite = Deep 90 % complete to tooth.
28. Molar relationship: L: ¾ Class II
Canine relationship: L: ½ class II
R: Class I

44. H.M is a 14.5 years old female, medicaly fit, with history of
routine dental check up, filling LR6. Presented complaining
of “ my upper teeth are malaligned “ . she has class II/II
incisor relationship based on class II skeletal pattern,slightly
decreased LFH, she has asymmetrical face with nose
deviated to the right side with compromised smile esthetics.
O.J of 2 mm, deep complete O.B to tooth. complicated lower
midline deviated to the right by 2 mm , moderate crowded
lower arch (localized anteriorly), moderate crowding in the
upper arch. Upper right 4 in scissor bite, molar on left side is
¾ class II , Canine on left side is ½ class II,.
45. Pathological problems :
1. poor oral hygiene
Developmental problems :
Patients’s concern : the malaligned
upper teeth.
Alignment and symmerty:
Asymmetric lower arch with 7mm crowding.
lingually inclined lower molars.
rotated LR3, LL3.
Retroclined lower incisor
Asymmetric upper arch with 5 mm crowding
retroclined upper incisors
UR4 scissor bite
rotated UL6,UR3 UL3
Skeletal and dental problems in transverse plane:
Asymmetric skeletal
upper midline deviated to the right by 2mm
lower midline deviated to the right by 2 mm
46. Skeletal and dental problems in A-Pplane:
Mild class 2 skeletal base (retrognatheic mandible)
insicor class 2 div 2
left Molar: Class II ¾
left Canine : Class II ½
Skeletal and dental problems in vertical plane:
slightly decreased LFH
increased complete OB
Soft tissue problems :
high lower lip line
obtuse nasolabial angle
47. Improve OH
Improve her smile by creating more normal gingival relationships , and smile
symmetry
Relief crowding in upper and lower arches , and level and align the arches
Correct rotated teeth
Corret retroclination of upper and lower teeth
Correct bolton discrepancy
Correct upper and lower midline shift
Correct scissor bite on upper right 4.
Accept class 2 skeletal base
Correct lower facial height.
Accept Asyymetrical face.
Achieve 2mm OJ
Achieve class I molar and class I canine relationship
Achieve class 1 incisor relationship
Achieve normal OB- correct edge-centroid relationship

6. Retention.
49. Short term:
Upper and lower hawley (full time wear
for 6 months, night time wear for another
6 months).
Long term :
Upper and lower permenant retainers from

50. Camouflage:
Skeletal is mild class 2 .
Chief complain is mainly related to malaligned teeth.
Nongrower patient.
Non –extraction:
- mild class 2 skeletal
- decreased lower facial height (deep bite)
- obtuse nasolabial angle
- Moderate crowding in the lower arch provided by IPS and
proclination of lower incisors and by uprightinng of the lingually tipped lower
buccal segment.
-Moderate crowding in upper arch. space can be gained by molar
distalization, proclination of upper incisors, and correction of rotated teeth.
Fixed Appliance
Alignment of teeth
Bodily movement
Upper and lower arch coordination
Upper roth : normal torque values needed
51. Modified Pendulum appliance with ABP
-unilateral distalization.
-decreased LAFH -Deep overbite.
-Class II ½ unit molar relationship.
-moderate crowding in the upper arch.
-Retroclined upper incisors.
- To disocclude the teeth
Nance
-to preserve cl I molar relationship
Lower stripping :
-to gain space in lower arch
- correct Bolton dixcrepancy.
Retention ( Upper and Lower fixed retainer ),
Upper fixed retainer: presence of rotated teeth
Lower fixed retainer: prevent late anterior mandibular crowding
