4. INTRODUCTION
 Diagnosis
Correct determination, discrimination, estimation
& logical appraisal of conditions found during
examination as evidenced by distinctive signs,
marks & symptoms

5. INTRODUCTION
 Comprehensive database:
Case history
Clinical examination
Study casts
Radiographs
Photographs
 Diagnostic aids: Essential & Supplemental

6. DIAGNOSTIC SETUP
 H.D. Kesling (1956)
 Supplemental diagnostic aid
 Practical aid in treatment planning
 Derive maximum clinical information
 A set of trimmed & polished casts

7. DIAGNOSTIC SETUP
 Individual teeth & associated alveolar
processes- sectioned off & replaced in desired
positions
 Simulate the various planned tooth
movements
 Not necessary to coordinate with
cephalometric tracing
 Allowance for inevitable anchorage loss

8. REQUIREMENTS
 Well trimmed casts
 Fret saw with blades
 Modelling wax
 Wax knife
 Alcohol torch/ Spirit lamp

9. PROCEDURE
 Maxillary & mandibular study casts prepared
 Bases trimmed parallel to the occlusal plane
 Horizontal cuts made in the mandibular cast
3mm below the gingival margin using
Fretsaw blade

11. PROCEDURE
 Vertical cuts are made to separate individual
teeth
 All teeth except second & third molars are
removed
 Mesial & distal ends of roots of teeth are
trimmed – seating in new position

13. PROCEDURE
 Wax blocks placed in the slits formed while
cutting the teeth away
 Mandibular incisors arranged on the study cast
at an angle of 65 degrees to the Frankfort
Horizontal plane
 Canines & premolars are placed in the correct
contact relationships

15. PROCEDURE
 If the remaining space is inadequate to receive
the first molars extraction indicated
 Eliminate 1st premolars from the setup & place
2nd premolars in contact with canine or perform
incisor or proximal stripping
 Maxillary teeth cut & repositioned in the wax
setup articulating them with the mandibular
setup

18. USES
 TSALD – directly visualised
 Estimates if uprighting of the 2nd molars could
solve the arch length discrepancy
 Visualizes complex orthodontic treatment
 Possibility of aligning incisors

19. USES
 Borderline cases:
 Extraction / non extraction
 1st premolar or 2nd premolar
 Possible types of occlusal arrangement in
abnormal occlusal problems
 Patient can be motivated- simulating various
corrective procedures

20. CONCLUSION
 Diagnostic setup – very valuable diagnostic
aid
 Routine use - better treatment plan & patient
motivation
