Problem List Dental : Impacted of upper right and left canines Spacing of upper and lower anterior teeth. •lower dental midline not coincident in relation facial midline. •upper dental midline not coincident in relation facial midline. Deep overbite Treatment objective Canines traction. Closig the space. (l e veli n g a nd al i gnm en t o f u pper and lower teeth) . Obtaining a coincident upper and lower midline in relation to facial midline . Obtaining normal bite.
Extraction approach (extraction of upper right and left deciduous canines) Mechanical Strategies: • For upper arch : 1- Installment of pre-adjusted edgewise brackets(Roth prescription) 2- Installment of trans palatal arch with hooks,then canine traction to the hooks. 3- Leveling and alignment Ni-Ti round (12.14.16.18) then 16X22 Nit- ti archwire thousands of an inch. 4- Installment of S.S retangular archwire (16X22) of an inch 5-midline correction For lower arch : 5 - Installment of pre-adjusted edgewise brackets(Roth prescription) 6- Leveling and alignment Ni-Ti round (12.14.16.18) then 16X22 Nit- ti archwire thousands of an inch 7- Installment of S.S retangular archwire (16X22) thousands of an inch 8 - Finishing and occlusal settling of the case Line of orthodontic treatment and mechanical strategies :
Case Summery: Sara taha ashree is a 22 -year-old fe male patient whose chief complaint is: “ my upper frontal teeth have spaces and I can’t smile” Clinical examination revealed normal profile, normal extra-oral features, and normal function. and normal TMJ function. Intra-orally he has Class I molar relation on right side and left side , , deep overbite ,normal overjet and normal soft and hard tissue. Cephalometric analysis: showed skeletal Class I relation, normal upper incisor inclination, normal lower incisor inclination, and normal upper and lower lips. . Study cast analysis: Space discrepancy 8 mm in upper arch and 3 mm in lower arch . Proposed treatment: extraction approach , utilizing preadjusted edgewise fixed appliance (Roth prescription) Leveling and alignment of the upper arch and lower arch Retention: upper and lower Hawely retainer
