Management of Class II Division I malocclusion with subdivision on left side by Camouflage Orthodontic Treatment - 8
Diagnosis:
A female patient came with the chief complain of forwardly placed upper front teeth. The extraoral examination reveals mesoprosopic faceform, mesoocephalic headform, convex profile, incompetent lips, acute nasolabial angle. The intraoral examination shows Class II molar and Class II canine relation on right side with spacing in upper anterior & crowding in lower anterior teeth. Diagnosis is Angle's Class II Division I malocclusion with subdivision on left side, spacing in upper anterior & crowding in lower anterior teeth.
Treatment Objectives:
- To correct proclination of upper anterior teeth
- To achieve ideal overjet and overbite
- To close spacing in upper anterior teeth
- To relieve crowding in lower anterior teeth
- To correct Class II molar and canine relation on right side
- To improve profile
- To correct nasolabial angle
- To correct smile
- Extraction irt 14,24,34,45
- Leveling and alignment
- Space Closure
- Finishing and detailing
Treatment Progress:
The orthodontic treatment is started with banding and bonding in upper and lower arches with standard 0.022 inch MBT preadjusted edgewise appliance. The initial leveling and alignment process is started. The sequential change of arch wires were 0.016 nickel‑titanium (NiTi), 0.017 x 0.025 NiTi, 0.019 x 0.025 NiTi, 0.019 x 0.025 SS. After the leveling & alignment is completed, extraction of all first premolars are performed. Then retraction is started on 0.019 x 0.025 SS wire by sliding mechanics. Class II elastics are given right side to correct right side Class II molar relation. Elastomeric chain is changed every six weeks. After space closure, finishing is done on 0.019 x 0.025 braided SS wire by settling elastics. The overall treatment duration is approximate 1.5 year. After removal of orthodontic appliance, removable essix retainer are given.
Treatment Results:
The post treatment photographs showed Class I molar and canine relation, ideal overjet and overbite, average nasolabial angle, competent lips, well coordinated arches. The profile is also improved. The pleasing smile is obtained with proper interdigitation of occlusion.
