Computer Diagnosis and Planning course

Course by: Bill Arnett

Duration:  5 hours 30 min

Computer treatment planning may be a complicated and little understood procedure. Planning begins with CBCT orientation – if orientation is incorrect, the surgical result will be incorrect. This module explores and defines orientation and profile/frontal planning.



1. Facial Analysis Part 1

  • How is facial change planned during bite treatment?
  • Does facial analysis determine how to correct the bite?
  • Does facial analysis determine where to place the class I bite in the face?
  • What are cranial base cephalometric inaccuracies which may produce facial decline?
  • Does cephalometric X-Ray orientation effect the facial result?
  • Does steepening the occlusal plane produce profile imbalance?

2. Facial Analysis Part 2

  • What determines where to position the class I bite correction?
  • How is the patient postured for the frontal facial exam?
  • Does the facial examination form list important measurements, norms, and possible treatments?
  • What key vertical facial traits are measured?
  • What are the 4 factors which determine the upper incisor exposure?
  • Are the canines leveled to the pupils?
  • What key facial outline traits are measured?

3. Facial Analysis Part 3

  • Does the facial exam form list profile traits, norms, and possible treatments?
  • What are the 3 profile projection groups?
  • What are the 6 ways of increasing chin projection?
  • Does the soft tissue cephalometric analysis quantify the clinical profile examination?
  • What is the upper Lip Mirror test? 
  • What determines where to place the upper incisor tip?

4. FAB Cephalometrics

  • Does FAB stand for face, airway, and bite cephalometrics?
  • What are the true vertical line and natural head posture used to measure the face?
  • How is the lateral cephalometric x-ray taken to avoid errors?
  • Is FAB more reliable for diagnosis and treatment than Steiner and Ricketts?
  • What 13 dental and skeletal measurements control profile esthetics and the airway?
  • When upper lip projection is normal, how many millimeters is it behind the nasal tip?

5. Hands-On 2D VTO

  • Does FAB stand for face, airway, and bite cephalometrics?
  • How many dental and skeletal measurements determine the projection and height of the facial profile?
  • How many steps are involved in the profile cephalometric treatment plan?
  • Why does orthodontic lower incisor proclination lead to the need for chin augmentation?
  • What determines where the maxillary incisors are placed in the face?
  • What are the conditions necessary to only operate the lower jaw?
  • What factors indicate the need for upper jaw surgery?

6. Hands-On 3D FAB

  • What is the image library?
  • How is computer surgery done accurately?
  • What are the harmony numbers?
  • Is the profile determined with cephalometric treatment planning?
  • Is the frontal view treated by orientation of the volume?
  • What is the source of profile treatment?
  • What is the source of frontal treatment?
  • What causes condylar torque?
