IOTN Esthetic ComponentNot Applicable

Diagnostic SummaryR.S is a 16 years old, female, denied any medical history. She came complaining that her upper teeth dont show while smiling.She has poor oral hygiene.Class III Incisors relationship based on mild skeletal Class III with Average anterior facial height.She has asymmetrical face with chin deviated to the Right side. Compromised smile esthetics.She has Class I molar with Class I canine relationships on right side and a Class I molar with ClassI canine relationships on left side. OJ is -1.2mm with decreased OB to 20% incompleteUpper midline shifted to the left by 1 mm and lower shifted to the right by 1 mm.Mild crowding in the upper and well-aligned lower arch.Crossbite on UR 1,2and UL 1.

Problem list Pathological problems:Poor O.H. Visible Plaque AccumulationLL6 needs refilling or crowning Patients concern I dont like how my upper teeth dont show when I smile Skeletal and dental problems in transverse plane:Chin deviated to the right side.Upper midline shifted to the left by 1mm.Lower midline shifted to the right by 1mm.Skeletal and dental problems in A-P :Skeletal Class III prognathic mandible

OJ -1.2 mmSkeletal and dental problems vertically Decreased OB. 20%

Treatment AimsImprove O.H.Restorative treatment LL6.Accept skeletal discrepancy.Accept facial asymmetry Correct Anterior crossbite.Correct centerlines shift.Achieve and maintain Class I molar and canine relationships.Achieve Positive OJ Increase OB.Finishing and detailing of occlusion.Retain corrected results

Treatment PlanNon-ExtractionO.H. improvement.Upper and Lower Fixed MBT 0.22 slot.Bite raising on the lower Incisors .Stripping in the lower arch6. Conventional Retention Upper/Lower Hawley Retainer.

High pull head gear Midpalatal closure: Females 12-13Males 13-1440

JustificationOHI : Visible Plaque Camouflage :Patients chief complaintAge of the patient Good vertical facial proportions Mild Class III skeletal within orthodontics treatment limitsNormal soft tissue features Non Extraction :Space will be provided by proclination of the upper incisors and stripping in the lower incisors Fixed appliance using MBT prescription: For 3D tooth movement .Maxillary incisors palatal torque.Retroclination of the lower incisors .

Justification Bite Raising : Disoclussion allow freedom in movement of upper incisors Lower stripping to gain space to retrocline lower incisors .Conventional Retention :Upper and Lower Hawley 6month full time wear and 6 month night time . After Achieving overbite the results are generally stable

Mechanics

To get further proclination of ULS, use MBT in the ULSLingual crown torque on LLS Contra-lateral canine brackets (to avoid LLS proclination)Lacebacks in LA (to avoid LLS proclination)Cinch back in LA (to avoid LLS proclination)Closing space created by stripping on a round wire in the lower arch will facilitate retroclination of the lower incisors.
