    Study Notes

    Introduction to Orthodontics II - 1602305 Dental Occlusion and Temporomandibular Joint Disorders

    • Course: Introduction to Orthodontics II, 1st Semester - 2024/2024
    • Course code: 1602305
    • Topic: Dental Occlusion and Temporomandibular Joint Disorders
    • Instructor: Dr. Yousef Herzallah
    • Week: 13
    • Year: 2024

    Orthodontics Topics

    • Occlusion and Malocclusion
    • Important Terminology
    • When To Treat
    • Indices Of Need
    • Classifying Malocclusions
    • Risks Of Orthodontic Treatment
    • Orthodontic Patient Assessment

    Orthodontic Patient Assessment

    • History and Concerns:
      • Dental History: Patients need to be in excellent dental health, frequently visit general dentists (GDPs). Details about: previous appliance therapy, previous extractions (timing, reason, complications), previous restorative or endodontic treatments. GDP and Orthodontists need good communication.
      • Medical History: Details of medical conditions are crucial: heart defects, infectious endocarditis, bleeding disorders, asthma, bisphosphonates, learning difficulties/behavior disorders. Epilepsy, Latex allergy, Nickel allergy, Diabetes.
      • Patient information and perception:Patient's age and growth status, social and behavioral factors (compliance), expressed concerns, expectations from treatment, comparing patient concerns with parent/GDP concerns, and comparing adult vs. child patient motivation and expectations.

    Clinical Examination

    • Anteroposterior:
      • Extra-oral: Maxilla to mandible relationship (Class I, II, or III).
      • Intra-oral: Incisor classification, overjet, canine relationship, molar relationship, anterior crossbite.
    • Vertical:
      • Extra-oral: Facial thirds, angle of lower border of mandible to maxilla.
      • Intra-oral: Overbite, anterior open bite, lateral open bite.
    • Transverse:
      • Extra-oral: Facial asymmetry.
      • Intra-oral: Centrelines, posterior crossbites.
    • Extra-oral-AP:
      • Zero Meridian (ZM), Facial Convexity Assessment (Class I, II, III), Palpation.
    • Extra-oral-Vertical:
      • Rule of Thirds, Mandibular Plane Angle.
    • Extra-oral-Transverse:
      • Bird's Eye View, Rule of Fifths.

    Clinical Examination - Intra-oral

    • Oral Health: Teeth present need to be noted. Pathology (Mucosal, Periodontal, Dental) needs to be identified. Evidence of trauma needs recording and further investigation. Optimal oral hygiene crucial before orthodontic treatment.

    • Dental Arch:

      • Crowding or Spacing (0-4 mm-Mild, 4-8 mm-Moderate, >8 mm-Severe).
      • Alignment of Teeth (Displacements or Rotations of teeth).
      • Inclination of the Labial Segments.
      • Depth of Curve of Spee (Affects space needs when treatment planning).

    • Intra-oral-AP:

      • British Standard Institute Incisor Classification (Class I, II div 1, II div 2, III).
      • Overjet (Normal: 2-4 mm).
      • Canine Classification (Class I, II, III).
      • Molar Classification (Class I, II, III).
      • Anterior Crossbite.

    • Intra-oral-Vertical:

      • Overbite (Normal: one-third to one-half coverage, Increased: coverage greater than one-half, Reduced: coverage less than one-third).
      • Anterior Open Bite.
      • Lateral Open Bite.

    • Intra-oral-Transverse:

      • Centrelines (Upper and lower centreline coincident with facial midline).
      • Posterior Crossbites.

    Diagnostic Records

    • Study Models: Produced using Angle's trimming technique.
    • Photographs: Extra-oral (natural head position) + intra-oral, serve as medicolegal record, useful short videos.
    • Radiographs: Check for presence/absence of teeth, stage of development, root morphology, ectopic/supernumerary teeth, dental disease, relationship of teeth to the skull base. Include Dental/Oral Panoramic Tomograph (DPT) / OPT and Lateral Cephalometric Radiograph.

    Problem List and Treatment

    • A funnel graphic displays the flow from historical records, examination and concerns to the problem list. From this, treatment aims, treatment plans and treatment delivery are generated. Also, Problem #1, Problem #2, Problem #3 are generated and aligned with Treatment Aims 1, 2, 3. Followed by Treatment Plan 1, Treatment Plan 2, Treatment Plan 3.
