Top Ten Lessons I Have Learned in Orthodontics
Richard McLaughlin, D.D.S.
AAO 2015San Francisco, CA
TOP TEN LESSONS I HAVE LEARNED IN ORTHODONTICS
1. Diagnosis and Treatment Planning
2. Importance of Staff
3. Bracket Placement
4. Arch Form
5. Non-extraction Cases
6. First Bicuspid Extraction Cases
7. Second Bicuspid Extraction Cases
8. Surgical Considerations
9. Finishing
10. Retention
The greatest challenges in
orthodontics are in the area of
diagnosis and treatment planning
1
4/8/2015
THIS CAN INCLUDE:
1) Incorrect diagnosis and/or treatment
planning
2) Lack of acceptance by the patient
DIAGNOSIS AND TREATMENT PLANNING
• 60% - 20% - 20% Rule
• Can be very time consuming
• We need an efficient and accurate system
ACHIEVING THE GOAL
A systematic approach to each
aspect of treatment

DIAGNOSIS AND TREATMENT PLANNING CHALLENGES
• Presentation of surgical cases
• Presentation of extraction cases
• Presentation of IPR cases
Build our story before
we tell the story
DIAGNOSIS AND TREATMENT PLANNING
History Clinical Exam Records
• TMJ’S and Musculature
• Airway
• Perio Status-and Soft Tissue
• Habits
• Facial and Skeletal Pattern
• Dentition

“ I DON’T USE CEPHALOMETRICS ANY MORE”

Why is this occuring
and
is there a solution?
Cephalometrics should provide
objective back-up to
subjective observations

With Class I occlusions,the occlusal plane can vary
from 80° to 110°, or a total 30°
This can effect the position of pogonion
by 1.5 to 2 cm

Orthodontists need to
dentally compensate incisors
in many cases
“There is often a tension
in orthodontics between
stability and esthetics”
