Diagnosis Treatment plan Mechanotherapy history Chief complaint Clinical Examination Paraclinical Examination Cast analysis radiography Photography Medical Dental Extra oral Intraoral
14 years old girl Chief complaint : crowded teeth MH: - DH: - TMJ Exam: -
Bilateral symmetry facial height(long) Lips: * together at rest * normal lip tension Tooth show : - Mentolabial sulcus: normal Extra oral examination Concave profile (Max retrusion/ man protrusion) High nasolabial angle
Intraoral Examination Interarch relationship - AP: *right molar(cl 3) *left molar(cl 3) *right canine cl 1 *left canine cl 1 * anterior cross bite : 1mm vertical:* overbite ( 4mm) - transverse * midline( upper & lower ok) * post. Right Cross bite
* functional shift on closure : anteroposterior * tooth size/arch size : maxillary anterior crowding
Intraoral Examination Intraarch assessment _ stage : permanent _ no asymmetry in dental arches _ TS/AL: maxillary space deficiency _oral hygiene _ periodontal status _ restorative status
