orhodontics or orthodontic space
closure to obviate the need for
prosthesis

29. Diagnostic Summary
A. Z. is a 25 year old male, medically fit, complaining “my teeth
are not straight”. He presented with a class I incisor relationship
on a class I skeletal base with slightly reduced lower facial
height. He has a normal overjet of 2 mm, 50% complete overbite,
with missing upper lateral incisors, retained primary canines,
missing all second premolars and upper right first premolar. He
has narrow upper arch and moderate crowding in the lower
arch, and a shifted upper and lower midlines of 2, and 3 mm to
the right correspondingly. He has class II molar and class I
canine relationships on the right side, class III molar and class
III ¼ unit canine relationship on the left side.
30. Problem List
1. Poor oral hygiene and gingival inflammation
2. Carious upper left primary canine, right upper and lower first molars
3. Generalized decrease in bone height
4. Pericoronitis on lower third molars
5. Chief complaint: poor smile esthetics with malaligned teeth
6. Asymmetric face with nose and philtrum deviated to the left
7. Short upper lip
8. Obtuse nasiolabial angle
9. Slightly convex profile
10. Short throat length
11. Canted occlusal line and narrow smile
12. Missing upper lateral incisors, with retained primary canines
13. Missing second premolars and upper right first premolar
14. Crossbite on the right from primary canine to first molar and upper left first premolar
15. V-shaped narrow upper arch
16. Upper central line shift of 2 mm to the right
17. Lower central line shift of 3 mm to the right
18. Moderate crowding in lower arch
19. Severely mesially tipped upper and lower right first molars
20. Class II molar relationships on the right and class III on the left
21. Canine relationships of class III ¼ unit on the left
31. Treatment Aims
Improve and maintain good oral hygiene throughout treatment
Accept facial asymmetry and skeletal relationship
Correction of crossbite
Achieve Class I canine relationships, and molar relationship on the left
side
Achieve full class II relationship on right side
Correct tooth alignment and proper angulation and inclination
Maintain overjet and overbite
32. Treatment Plan
1. Improvement of oral hygiene
2. Upper and lower fixed appliance
3. Space closure for missing premolars
4. Extraction of upper primary canine and prosthetic replacement with
implants to restore lateral incisors
5. Finishing
6. Retention
33. Treatment Mechanics
1. Roth prescription, .022” slot
2. Include upper and lower second molars
3. Start with alignment and leveling using NiTi wire sequence
4. Upper arch expansion with expanded SS wires
5. Distalize lower left molars and maintain upper left molars in position utilizing
micro implants and closing coil spring
6. Closure of lower space towards the left side to correct lower midline shift
7. Upright lower right second molar first then first molar utilizing micro implants
34. Retention Protocol
Upper and lower Hawley retainers
Maintain primary canine extraction space with acrylic teeth
until prosthetic replacement is carried out
24 hours wear for 3 months, then 12 hours/day for 1 year
35. Justification
Fixed appliance: due to the necessity of precise control of tooth movement in the
three dimensions
Roth prescription slot .022”: due to use of sliding mechanics
Upper arch expansion: to correct crossbite and provide space for space opening
Space closure of the left upper and lower buccal segments: acceptable
angulation of upper and lower first molars, and midline shift
Space closure for the right upper and lower buccal segments: due to acceptable
contact between teeth
Extraction of upper primary canines: because of increased crown/root ratio and
poor prognosis and unacceptable esthetics. Extraction delayed to maintain bone
height.
