INTRODUCTION:

A Visual Treatment Objective (VTO) islike a blueprint used in building a house.

It is a visual plan to forecast the normalgrowth of the patient and the anticipated

inuences of treatment! to establish theindividual objectives we want to achievefor that patient.

Treatment for a growing patient must be

planned and directed to the face andstructure that can be anticipated in thefuture! not to the skeletal structure thatthe patient presents initiall".

The treatment plan should takeadvantage of the bene#cial aspects of

The Visual Treatment Objective permitsthe development of alternativetreatment plans.

After setting up the teeth ideall" withinthe anticipated or &grown' facial pattern!the orthodontist must decide how far hemust go with mechanics and orthopedics

to achieve his goals! whether it is possible to achieve them! and what thealternatives are.

A stepb"step procedure to construct a

VTO for ase * in the following se+uence(putting in average growth for anestimated two"ear period of activetreatment and the objectives ,

-. the cranial base prediction. the mandibular growth prediction

/. the ma0illar" growth prediction

1. the occlusal plane position2. the location of the dentition

3. the soft tissue of the face

SUPERIMPOSITION:

After completion of the steps! Take VTOand superimpose it in the #vesuperimposition areas to establish

individual objectives for the case. The use of superimposition areas and

evaluation areas to establish treatmentdesign include changes due to normal

growth and changes due to varioustreatment mechanics are di%erent foreach individual because of his individualmorpholog" and facial t"pe.


11/25

In order to forecast e%ectivel" anddecide upon the correct treatmentdesign! it is necessar" for us to

#rst understand the individual patientand describe his basic facial! skeletaland dental structures.

secondl" we should be able to anticipate

normal growth in amount and directionin the various areas of the face and the

jaws.

thirdl" we should understand the

response of his individual skeletal and

The cephalometric 0ra" and tracing areused as the basic tools of treatmentdesign and the following four objectives

are A basic description of the cranial

structures.

An anal"sis of normal growth change

A treatment design An evaluation of growth and treatment

results.

The #ve superimposition areas are used toevaluate the face in the following order,

-. The chin.

. The ma0illa./. The teeth in the mandible.

1. The teeth in the ma0illa.

2. The facial pro#le.
