Orthodontic treatment of Class I malocclusion with severe crowding & rotations - 3
Diagnosis:
A female patient came with the chief complain of irregularly placed upper and lower teeth. The extraoral examination reveals mesoprosopic faceform, mesoocephalic headform, straight profile, competent lips, average nasolabial angle. The intraoral examination shows Class I molar relation, Class I canine relation with crowding in upper & lower anterior teeth, crossbite irt 15, severe rotation irt 15. Diagnosis is Angle's Class I malocclusion with crossbite irt 15, upper and lower crowding.
Treatment Objectives:
- To correct crowding in upper & lower anterior teeth
- To correct crossbite
- To achieve ideal overjet and overbite
- To correct smile
Treatment Plan:
- Non-Extraction
- Leveling and alignment
- Inter-proximal reduction
- 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 on 0.014 nickel‑titanium (NiTi) arch wire and GIC cement is placed on posterior teeth to open the bite. For the correction of upper right second premolar, couple force is applied. The inter-proximal reduction is performed in lower anterior teeth. The sequential change of arch wires are 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 crossbite is relieved and leveling & alignment is completed, posterior GIC bite block is removed. Finishing & detailing is done on 0.019 x 0.025 braided SS wire by settling elastics. The overall treatment duration is approximately 1 year. After removal of orthodontic appliance, lingual fixed retainer and removable essix retainer are given.
