35. Diagnostic summary
• M.A 15,5months years old female, denied any medical problem, presented
with concern unerupted tooth in her lower jaw & rotated upper anterior
teeth, good oral hygiene and caries in UL1st molar.
• She has a class I incisors relationship based on class III skeletal pattern,
average lower anterior facial height , straight profile, and asymmetrical soft
tissue face.
• She has missing UR 2nd premolar, over jet 2mm, incomplete overbite 50%,
no crowding in upper and lower arches, rotated lower Rt & Lt 2nd premolars,
distally tilted LL lateral incisor &LL canine, partially erupted LL 1st premolar
&LL 2nd permanent molar, retained upper primary right 2nd molar with no
mobility and good bone level, rotated upper left 2nd premolar& Rt and Lt
central incisors, lower midline shifted to the left side 2mm.
• She has cl III ¼ unit molar relationship in Rt side, cl I in Lt side & cl I canine
relationship in Rt side, cl II1/2 unit in Lt side and increased curve of spee.
36. Problems list
Pathological problems:
Caries in UL 1st molar.
Patient’s concern:
I have unerupted tooth in my
lower jaw and rotated upper
anterior teeth.
Skeletal problems:
Class III skeletal pattern.
Soft tissue problems:
• Asymmetrical face.
Dental problems:
• Missing upper right 2nd premolar and
retained upper primary right 2nd molar.
• Partially erupted LL 1st premolar.
• Rotated lower Rt & Lt 2nd premolars.
• Distally tilted LL lateral incisor &LL
canine.
• Rotated upper left 2nd premolar& Rt and
Lt central incisors.
• Lower midline shifted to the right side
2mm.
• Molars are cl III ¼ unit in Rt side and cl I
in Lt side.
• Canines are cl I in right side and cl II ½
unit in left side.
• Increased curve of spee.
37. Treatment Aims
Restoration of carious tooth.
Correct the patient complaint.
Accept skeletal cl III pattern.
Accept soft tissue problems.
Accept retained upper primary right 2nd molar and consider
future artificial replacement for the missing UR 2nd premolar.
Achieve class I molar and cl I canine relationship in Rt&Lt side.
Correction of rotated and tilted teeth.
Correction of dental midline shift in lower arch.
Correction of curve of spee.
38. Treatment plan: “ Non- Extraction Case”
“ camouflage case ”
1. Refer patient to cons. clinic to treat carious tooth.
2. Oral hygiene instruction.
3. Lower holding arch.
4. Upper & Lower Fixed Appliance: using SWA technique.
“ Pre-adjusted edgewise, Roth prescription, slot 0.022”
5. Interproximal reduction of UR 2nd primary molar.
6. Retention:
( Long term) lower bonded retainer 3-3.
Upper bonded retainer 1-1.
( Short term) Upper and lower Hawley retainer appliance.
39. Justification
1. Camouflage :
Patient passed the peak of growth spurt.
Mild cl III skeletal.
Good vertical facial proportion.
No dental compensation.
Normal overbite and overjet.
2. Non- extraction :
Upper and lower arches with no crowding.
Space can be gained by correction of rotated, tilted teeth and arch
wire expansion .
40. 3. Refer patient to cons. clinic to treat carious tooth.
4. Oral hygiene instruction to maintain stability of the
periodontal tissue.
5. Lower holding arch:
to prevent distal tipping of LL6 during opening space for
LL4 which may interfere with LL7 eruption, and maintain
cl I molar relationship.
As anchorage – to maintain molar relationship – to aid in
traction if the case necessitates .
6. Fixed appliance using Roth prescription:
For 3D tooth movement.
Average torque is needed.
41. 7. Interproximal reduction of UR 2nd primary molar:
Interproximal reduction 2.5mm(M&D sides) of UR 2nd
primary molar to achieve cl I molar relationship in the Rt side and
create accurate space for future artificial replacement of UR 2nd
premolar.
8. Retention:
(Long term )
Lower fixed retainer (3-3) to stabilize the position of anterior teeth and
prevent lower late labial segment crowding .
To maintain aligment of rotated LL3
Upper fixed retainer (1-1) to stabilize the position of central incisors.
(Short term)
Upper and lower Hawley retainer appliance for more settling and
stability.
42. Mechanics
• At direct bonding of U&L fixed appliance:
- Raising bite at lower Rt&Lt 6 –to disarticulate the occlusion in the early
phase of aligment
- lace back in all quadrents except lower left one ( 6 – 3) .
• At working arch wire (19 X 25 S.S):
- Open spring between LL3&LL5 to create space for LL4, achieve cl I
canine in Lt side and correct lower midline.
- Bonding of LL4 and piggyback for traction of partially erupted LL 4.
• At finishing stage:
- Remove lower holding arch.
- TMA wire ( 21 X 25 ) for root parallism.
- CSF .
