This case was prepared as part of a requirement during our study of the orthodontic courses.
Helps very much in elaborating the proper way to diagnose, hope you find it useful...

Orthodontic Case Presentation

  1. 1. Orthodontic CASE PRESENTATIONPrepared by: Majd Hasanin
  2. 2. • Age: 22 Years Old• Chief Complaint: Orthodontic Consultation
  3. 3.  Medical History: (Medically Fit).• Dental History:o Regular check up every 6 months.o Brushes 3 times / day.o Doesn’t floss.o Previously orthodontically treated for 4 yrs;(from grade 11 – 2nd year at uni).o Restorations: U: (# 16, 15, 25, 26 ), L: (#. 37, 36, 35, 45, 46, 47)…oBoth arches are restored with amalgam except for tooth # 25, amalgam has beenrecently replaced with composite restoration.o No history of oral or dental trauma.o Occlusal caries found during dental charting in teeth # 17, 27. Habit: (Chews gum 9 hrs / day & biting nails).
  4. 4.  Anteroposterior (A-P):- Profile: Slightly convex
  5. 5. • Vertical:- Lower anterior facial height: Normal.
  6. 6. • Transverse (non smile):-Symmetrical Face to a greatextent, “mesiofacial”.
  7. 7. •Transverse (Smiling):-Normally leveled occlusalplane(no canting)-Upper midline to facial midline:Coincident ,-Lower midline to upper midline:Off to the left side by 0.5mm.
  8. 8. •Soft Tissue:-A-P: - NLA: Acute,-Vertical: - Competent lips - Smile line: low-Transverse:- Smile: wide .
  9. 9.  Tempro-mandibular Joint (TMJ):- Clicking.- Normal range of motion.- Deviation to Rt. In Opening.
  10. 10. • Gingiva: Color: pink, Texture: normal, Shape: scalloped.• Teeth: Caries, cracks, fillings.• Frenums: Normal frenal attachmentlevel.

  14. 14. • Inter-arch: Maxilla: 37 mm, Mandible: 27 mm.• Anteroposterior:Over Jet (OJ) = 1 mmRt. Molar: II half unit. Lt. Molar,: I.Rt. Canine: I. Lt. Canine: II half unit.
  15. 15. • Vertical:• Over Bite (OB) = 4 mm ( 50 %)• Rt side: premolar touching the curve,1 mm of curveof Spee on the Lt.
  16. 16. • Transverse:• Lower midline to upper dental midline shift by 0.5mm to the left.

  18. 18. • Maxillary arch:- Symmetry: Symmetrical to a greatextent.- rotations: U Rt Canine.- Intercaninewidth:35mm- intermolarwidth:47mm-Number of teeth: missing 1st premolars(Rt & Lt).• Mandibular arch:- Symmetry: Symmetrical to a greatextent.- rotations: L Lt Canine & 2nd Premolar.- Intercaninewidth: 27.5mm- intermolarwidth:43mm- Number of teeth: missing 1st premolars(Rt & Lt).
  19. 19. • Skeletal and dental problems in antro-posterior plane:• Class II skeletal pattern, slight convex profile, with slightly prognathinc maxillary & mandibular bone.• Class I malocclusion.• Molar Rt. Cl. II (half unit).• Canine Lt. Cl. II (half unit).• Slightly proclined upper incisors.•Over-jet (OJ); 1 mm.
  20. 20. • Skeletal and dental problems in vertical plane:• Increased overbite; 4mm (50%).• Rt side: premolar touching the curve,1 mm of curve of Spee on the Lt.
  21. 21. • Skeletal and dental problems in transverse plane:• No facial asymmetry.• Slight Lower midline shift, to the Lt by 0.5 mm.• No posterior cross-bite but the left 1st molar relationship is liable to a cross-bite (because of its position)..
  22. 22. • Soft Tissues• Anteroposterior:Acute NLA. Vertical:Slightly low smile line.
  23. 23. •Alignment and symmetry in each arch:• The upper arch: Symmetry: Symmetrical to a great extent. Rotations: U Rt Canine (clockwise). Space Analysis: (0mm), no space nor crowding.• The lower arch: Symmetry: Symmetrical to a great extent. Rotations: L Lt Canine (clockwise) & 2nd Premolar (counter-clockwise). Space Analysis: (-4.5mm), moderate crowding.
  24. 24. Summary: Patient is 22 yr old, healthy, female, asking for orthodonticconsultation, with acute NLA. She has Class II Lt Canine relationship (by half unit) andClass II Molar relationship (by half unit) & the left side molar relationshiis liable to be shifted into a unilateral cross-bite.with increased overbite (4 mm), 50%. A Class II skeletal pattern with slightly increased facialproportion. She has moderate lower crowding with severalU & L rotations.Also with a (0.5 mm) lower midline shift to the left side.
