Orthodontics Justified

spirit

mindbody

“ If there is a defect on the soul, it cannot be corrected on the face, but if there is a defect on the face and one corrects it, it can correct a soul. “ - Jean Cocteau

Esthetics primarily responsible for Orthodontics

Appearance - The most important motivating factor for treatment.

Physically attractive people achieve higher levels of success in life than unattractive peopleBreece & Nieberg JCO 1986

Reasons for seeking orthodontic treatment : Malaligned teeth 84% Advice of dentist 52% Facial appearance 41%

Self concept in class II malocclusion and early treatmentDan C et al Angle Orthod. 65(6) 411, 1995Silver Platter Search

Information and AwarenessPatient empowermentA right to participate in the decisions and entitled to results

“Dentofacial Appearance is a significant predictor of orthodontic patients expectations of treatment”Am J Orthod Dentofacial Orthop 2003; 123-127

TimeSociety driven by speed !!Service on Demand,Instant gratification

The Face“A singular structure that teems with

subtletiesAn enchanted terrain,a zone of sensuality

A playground of secrets,a glory of function”

Daniel McNeill Facial Appearance :-The most important characteristic in relation to self image and self esteemPeople Dissatisfied with Facial appearance express more dissatisfaction with teeth than any other feature !!

Three dimensional treatment goals

4th Dimension TIME !!The 5th Dimension Function

1. Do traditional strategies and goals in orthodontics still hold good ?

Is there a new paradigm in orthodontics ?

o Facial / Dental aesthetics decide successful outcome both may not correlateo Anterior Smile Aesthetics critical for the patiento Alteration of the skeletal bases needs to be harmonized with dentoalveolar modification

o Orthodontics and surgeons – a synergism !!

Success !!

ORTHODONTIC LIMITATIONS

Angle – Class 1 molar Relation ship 1925 – 1945

Tweed – Lower Incisor Position 1945 –1985

Surgical influence – Upper incisors/positioning anterior 6 teeth

Cephalometrics – What Value ?

Measurements based on cranial base landmarks –inaccurate in defining clinical profile Disconnect between hard & soft

tissues! No measurement is 100% accurate Soft tissue thickness / axial

inclination of incisors – the most important variables in inaccuracy

Michels & Tourne Int J Adult orthod orthog Surg 1990 5 (1) 43-52www.indiandentalacademy.com

JCO Survey 99 – traditional Ceph Analysis used by 94% orthodontistsIs it a Problem ?• Measure skeletal and dental relationships• Measure to cranial base • Soft tissue/ profile correlation ?•Did we forget to reintegrate soft and hard tissues ??

Face First – The Emerging Paradigm

NO CORRELATION BETWEEN NORMSAND PROFILE BALANCE !!OCCLUSAL /DENTOALVEOLAR CORRECTION BASED ON NORMS – LESS THAN OPTIMAL FACIAL RESULTS

PRE-TREATMENT

POST-TREATMENTwww.indiandentalacademy.com

Inheritance or mind set?Is Traditional Cephalometric and model diagnosis relevant towards a comprehensive treatment outcome ?Evidence :- Changes in facial profile during orthodontic treatment with extraction of first four premolars Am J Orthod Dentofac Orthop 95(3):220-30 Mar 89

Dobrocky and Smith found • 160 orthodontic patients treated to Class 1 models • 15% of lips excessively flat !• 30.6 % nasolabial angles excessively obtuse !!( >120)
