21. Facial and Dental Appearance
1. The face (macroesthetics)
2. Smile Frame (miniesthetics)
3. Teeth (microesthetics)
22. Smile analysis
The smile index = intercomisure width/ interlabial gap on
smiling
=7.3/1.5=4.8 (Ackerman et al )1998
** The lower the smile index, the less youthful the smile appear
Asymmetric smile
The buccal corridor ratio=(inner commissure width-visible
maxillary dentition)/inner commissure x 100%
(5-3.9)/5=15%
Medium- smile
(Frush and Fisher) 1958

same gingival level

-Amalgum restorations on LR6,UR6
-No other apparent pathologies

• Rt : palatal / Lt: within the arch
50. Prognosis
1. Canine angulation to the midline
2. A-P position of the canine apex
3. Vertical height of the canine crown
4. Canine crown overlap to the adjacent incisor
• power and short
51. 1. Canine angulation to the midline
• Grade 1=0-15 degree
• Grade2=16-30
• Grade 3= more than 30
• Average
52. 2. A-P position of the canine apex
• Grade 1: Above the region of the
canine position
• Grade 2: Above the upper first
premolar region
• Grade 3: Above the upper
second premolar region
• Average
53. 3. Vertical height of the canine crown
• Grade 1: Below the level of the CEJ
• Grade 2: Above the CEJ, but less than
half way up the root
• Grade 3: More than half way up the
root, but less than full root length
• Grade 4: Above the full length of the
root
Good
54. 4. Canine crown overlap to the adjacent incisor
• Grade 1: No horizontal overlap
• Grade 2: Less than half the root width
• Grade 3: More than half, but less than
the whole root width
• Grade 4: Complete overlap of root
width or more
• Good
57. Diagnostic Summary
• Y.K 12yrs- 5 months old male pt , MF, complaining of not having
straight teeth. Patient has fair-poor OH, a class II div 1 Malocclusion
on a class II skeletal base with increased vertical dimension. He has a
symmetrical Face with compromised smile esthetics. Complicated by
impacted upper canines and lower Rt canine. He has a ½ unit II molar
on left side, class I on right side. OJ is 4mm , OB is increased. Lower
midline is shifted 1 mm to the Rt. Upper arch has moderate crowding,
and severe crowding in the lower.
58. Problem List
• Skeletal and dental problems in transverse plane:
o
o Lower midline shifted 1mm to the right
o
• Skeletal and dental problems in A-P plane:
• Clinically convex profile
• Class 2 Skeletal base ( retrognathic mandible)
• Oj 4mm
o Lt Molar : ½ unit II
o Incisor class II div 1
• Skeletal and dental problems in vertical plane:
o Slightly increased LFH
o Increased OB
o 3 mm depth curve of spee
Pathological problems:
• Pathological problems:
• Poor OH
• Yellow discoloration around the teeth in buccal
segment
• Developmental problems
DevePatient’s concern the malaligned teeth
• Smile esthetics: compromised smile complicated
by impacted canines
• Alignment and symmerty:
o Asymmetric lower arch with with 9 mm
crowding
o Asymmetric upper arch with 7.5mm crowding
o Rotated teeth
o Impacted Ul3,UR3,LR3
59. Treatment Aims
• Improve Oral hygiene
• Improve his smile by creating more normal gingival relationships , and smile symmetry
• Relief crowding in upper and lower arches , and align the teeth (C/C)
• Correct rotated teeth
• Traction and Open space for the impacted UL3,UR3,LR3
• Correct lower midline shift
• Correct class 2 skeletal base( achieve better facial profile)
• Achieve 2mm OJ
• Achieve class I molar and canine relationship
• Achieve class 1 incisor relationship
• Restrain vertical growth
• Achieve normal OB
• Flaten curve of spee
• Finishing and detailing of occlusion.
• Retain corrected results
60. Treatment plan
1. OHI
2.Anchorage: high pull headgear, T.P.A and lingual bar
3. Upper, Lower fixed appliance(SWA MBT, roth)
4.Surgical exposure for UL3,UR3, remove soft tissue around LR3 +
traction
5.Extraction
6. Retention
61. Retention Protocol
• Short term:
• Upper and lower modified Hawley retainers (full time wear for 6
months, night time wear for another 6 months)
• Long term :
• Upper and lower permeant retainers from 3-3 (braided steel wire of
17.5 mil
62. Justification
• Anchorage reinforcement is needed because of
Traction of the displaced canines to the occlusion.
Transverse anchorage during canine traction
Preserve the extraction space.
63. Justification
• Extraction :
• Normal NLA
• Normal incisal show
• Thin gingival biotype around LLS
• severe crowding in lower arch, moderate in upper arch
• Upper 4’s to allow space for the impacted canines
• Upper canines has good prognosis
• Fixed Appliance
• Bodily teeth movement is required.
• Alignment of teeth.
• Upper MBT :to avoid retroclination of the incisors while retraction
• Lower roth: average torque needed
• Close the extraction spaces.
• Preserve / correct teeth torque.
64. Treatment details and mechanics
1. Full records
2. separators around 6’s
3. Band selection: impression for T.P.A + lingual bar
4. Cementation of T.P.A +lingual bar +delivery of headgear (wear time 8-10
hrs/day) , give instruction about how to wear it
5. Direct bonding of the brackets( upper MBT, Lower roth) positioning the
brackets incisaly to control the bite
6. Refer to surgery for exposure of canines +place attachemts
7. After assurance that canines are moving(not ankylosed) refer to extract
